• Set up Gitosis, but can't clone

  - by Tim Rupe

  I've set up Gitosis on a remote Ubuntu box which I will refer to as linuxserver as my host in the following commands. I'm also connecting from a Windows box using Cygwin. I followed the instructions according to: http://scie.nti.st/2007/11/14/hosting-git-repositories-the-easy-and-secure-way I had no problems up until I needed to clone the gitosis-admin repository to my local machine git clone git@linuxserver:gitosis-admin.git When I do this, the command executes, but hangs there displaying nothing until I ctrl-c to get back to a command prompt. No messages are displayed at all. I'm pretty sure I have my ssh keys set up properly, because logging in using "ssh linuxserver" into my regular account works perfectly without asking for a password. Edit: Over the weekend I set up a near identical Ubuntu box at home, and had no problem setting up Gitosis. The only difference was that I was connecting from OSX instead of Cygwin. Edit: I've also discovered that when using the Bash Shell provided with "Git Extensions", I have no problems, so the issue definitely seems to be some kind of Cygwin conflict. Edit: Just an update, but about a month after posting this question, I switched to Mercurial, and found that I prefer it much more than git. Thanks for the suggestions, but I don't plan on going back to git to try any of them out.

• GitHub solution for personal repo

  - by Luke Maurer

  So I've got my private SVN repo on my home server, and it has maybe 30 different modules thrown together in it, ranging from abortive throw-away larks to a few endeavors that might actually go somewhere someday. But a recent filesystem failure (BTW, never ever EVER use XFS without a battery-backed hardware RAID) has me spooked and thinking of using a DVCS for all that. I've also just had quite the swig of the Git koolaid, and I've been working with GitHub of late, so that's where I'm looking right now. Of course, it would be silly to shell out major cash for a separate private Git repo for every little project, and I don't want to have to be selective about what I throw up there (I love all my children :-D ), so I'll have to be somewhat creative about this. I can happily use SSH to my home box to use Git the way I've been using SVN, and I'm thinking from there I could amalgamate everything into, say, a big project with 30 submodules, which I then push to GitHub. What'd be a sane way to set this up? Does using submodules sound feasible? How do I sync it all to my private GitHub repo? Cron job? Git hook? I'd love to hear it if anyone's done something similar. I'm not really married to Git or GitHub, so a sufficiently compelling feature of another solution might sway me. But if your answer does involve a different system (especially a different VCS), be advised it'll be a tougher sell :-)

• Is there a good way of automatically generating javascript client code from server side python

  - by tat.wright

  I basically want to be able to: Write a few functions in python (with the minimum amount of extra meta data) Turn these functions into a web service (with the minimum of effort / boiler plate) Automatically generate some javascript functions / objects for rpc (this should prevent me from doing as many stupid things as possible like mistyping method names, forgetting the names of methods, passing the wrong number of arguments) Example python: def hello_world(): return "Hello world" javascript: ... <!-- This file is automatically generated (either dynamically or statically) --> <script src="http://myurl.com/webservice/client_side_javascript"> </script> ... <script> $('#button').click(function () { hello_world(function (data){ $('#label').text(data))) } </script> A bit of research has shown me some approaches that come close to this: Automatic generation of json-rpc services from functions with a little boiler plate code in python and then using jquery and json to do the calls (still easy to make mistakes with method names - still need to be aware of urls when calling, very irritating to write these calls yourself in the firebug shell) Using a library like soaplib to generate wsdl from python (by adding copious type information). And then somehow convert this into javascript (not sure if there is even a library to do this) But are there any approaches closer to what I want?

• Gzip and subprocess' stdout in python

• DVCS with a Windows central repository

  - by Mikko Rantanen

  We are currently using VSS for version control. Quite few of our developers are interested in a distributed model (And want to get rid of VSS). Our network is full of Windows machines and while our IT department has experience maintaining Linux machines they would prefer not to. What DVCS systems can host their central repository on Windows while providing.. Push access to the repository. Basic authentication. Mostly just a way to allow or deny access to the whole repository. No need for fine grained access. Server process so users don't need write right to the repository reducing the risk of accidentally messing with it. On the client side a GUI such as Tortoise would be more or less a requirement (Sorry, Windows shell sucks. :|). Ease of installation would be a huge plus as our IT department is already quite low on resources. And using windows credentials for authentication would be an advantage but not a requirement as long as the client is able to store the credentials. I have had a (really) quick look at Git, Mercurial and Bazaar. Git seemed to use ssh or simple WebDAV for repository access, requiring write permission for the users. Mercurial had a built in http server, but this seemed to be only for pull purposes. Update: Mercurial supports push as well. Bazaar Seemed to use sftp for repository access, again requiring a write permission for the users. Are there windows server processes for any DVCS systems and has anyone managed to set one up in a Windows land? And apologies if this is a duplicate question. I couldn't find one. Update Got Mercurial working for push purposes! Detailed list what was required can be found as an answer below.

• python eval weirdness

  - by amadain

  Hi Folks I have the following code in one of my classes along with checks when the code does not eval: filterParam="self.recipientMSISDN==tmpBPSS.split('_')[3].split('#')[0] and self.recipientIMSI==tmpBPSS.split('_')[3].split('#')[1]" if eval(filterParam): print "Evalled" else: print "Not Evalled\nfilterParam\n'%s'\ntmpBPSS\n'%s'\nself.recipientMSISDN\n'%s'\nself.recipientIMSI\n'%s'" % (filterParam, tmpBPSS, self.recipientMSISDN, self.recipientIMSI) I am not getting anything to 'eval'. Here are the results: Not Evalled filterParam 'self.recipientMSISDN==tmpBPSS.split('_')[3].split('#')[0] and self.recipientIMSI==tmpBPSS.split('_')[3].split('#')[1]' tmpBPSS 'bprm_DAILY_MO_919844000039#892000000' self.recipientMSISDN '919844000039' self.recipientIMSI '892000000' So I used the outputs from the above to check the code in a python shell and as you can see the code evalled correctly: >>> filterParam="recipientMSISDN==tmpBPSS.split('_')[3].split('#')[0] and recipientIMSI==tmpBPSS.split('_')[3].split('#')[1]" >>> tmpBPSS='bprm_DAILY_MO_919844000039#892000000' >>> recipientMSISDN='919844000039' >>> recipientIMSI='892000000' >>> if eval(filterParam): ... print "Evalled" ... else: ... print "Not Evalled" ... Evalled Am I off my rocker or what am I missing? A

• How to set permissions or alter a git commit process when using local repositories

  - by Tony

  I have a server that contains a central git repository and one of my co-worker's development environment. My co-worker's repository's origin is the central git repository and he pushes there when he has some code to share. Likewise, I develop locally and push to the central git repository when I have some code to share, so my repository's origin is also the central git repository. The issue is that I have the central git repository under a "git" user's home directory. So when I push I am actually SSH'ing into the the server as the "git" user. To be even more clear, my config has these lines: $ more .git/config [remote "origin"] fetch = +refs/heads/*:refs/remotes/origin/* url = [email protected]:fsg [branch "master"] remote = origin merge = refs/heads/master When I push, git handles this SSH + push seamlessly with I am guessing some sort of git shell. The issue is that when my coworker pushes, he is logged in as himself for a user and gets a bunch of crazy permission errors. Is there a typical way to solve this problem without opening up git's directories to a group? I think this will be problematic when I push and therefore overwrite the the repository and those permissions are reset. Thanks!

• Powershell 2.0 Hang When Run From MsDeploy pre- post- ops using c/

  - by SonOfNun

  I am trying to invoke powershell during the preSync call in a MSDeploy command, but powershell does not exit the process after it has been called. The command (from command line): "tools/MSDeploy/msdeploy.exe" -verb:sync -preSync:runCommand="powershell.exe -NoLogo -NoProfile -NonInteractive -ExecutionPolicy Unrestricted -Command C:/MyInstallPath/deploy.ps1 Set-WebAppOffline Uninstall-Service ",waitInterval=60000 -usechecksum -source:dirPath="build/for-deployment" -dest:wmsvc=BLUEPRINT-X86,username=deployer,password=deployer,dirPath=C:/MyInstallPath I used a hack here (http://therightstuff.de/2010/02/06/How-We-Practice-Continuous-Integration-And-Deployment-With-MSDeploy.aspx) that gets the powershell process and kills it but that didn't work. I also tried taskkill and the sysinternals equivalent, but nothing will kill the process so that MSDeploy errors out. The command is executed, but then just sits there. Any ideas what might be causing powershell to hang like this? I have found a few other similar issues around the web but no answers. Environment is Win 2K3, using Powershell 2.0. UPDATE: Here is a .vbs script I use to invoke my powershell command now. Invoke using 'cscript.exe path/to/script.vbs': Option Explicit Dim oShell, appCmd,oShellExec Set oShell = CreateObject("WScript.Shell") appCmd = "powershell.exe -NoLogo -NoProfile -NonInteractive -ExecutionPolicy Unrestricted -Command ""&{ . c:/development/materialstesting/deploy/web/deploy.ps1; Set-WebAppOffline }"" " Set oShellExec = oShell.Exec(appCmd) oShellExec.StdIn.Close()

• Nothing gets displayed when debugging Microsoft Surface

  - by leftend

  I am trying to write my first Microsoft Surface application, and am doing the development on the Surface unit itself. I successfully re-created the quick "Photos" application that is shown on the PDC Video, however, now that I'm trying to create my own app - nothing actually shows up when I run it. I'm mainly just adding ScatterViews right now - and they show up fine in the designer, but as soon as I hit F5 - the shell is shown on the surface - but none of the ScatterViews show up. Here's my xaml code so far.

• Port Win32 DLL hook to Linux

  - by peachykeen

  I have a program (NWShader) which hooks into a second program's OpenGL calls (NWN) to do post-processing effects and whatnot. NWShader was originally built for Windows, generally modern versions (win32), and uses both DLL exports (to get Windows to load it and grab some OpenGL functions) and Detours (to hook into other functions). I'm using the trick where Win will look in the current directory for any DLLs before checking the sysdir, so it loads mine. I have on DLL that redirects with this method: #pragma comment(linker, "/export:oldFunc=nwshader.newFunc) To send them to a different named function in my own DLL. I then do any processing and call the original function from the system DLL. I need to port NWShader to Linux (NWN exists in both flavors). As far as I can tell, what I need to make is a shared library (.so file). If this is preloaded before the NWN executable (I found a shell script to handle this), my functions will be called. The only problem is I need to call the original function (I would use various DLL dynamic loading methods for this, I think) and need to be able to do Detour-like hooking of internal functions. At the moment I'm building on Ubuntu 9.10 x64 (with the 32-bit compiler flags). I haven't been able to find much on Google to help with this, but I don't know exactly what the *nix community refers to it as. I can code C++, but I'm more used to Windows. Being OpenGL, the only part the needs modified to be compatible with Linux is the hooking code and the calls. Is there a simple and easy way to do this, or will it involve recreating Detours and dynamically loading the original function addresses?

• Directly call distutils' or setuptools' setup() function with command name/options, without parsing

  - by Ryan B. Lynch

  I'd like to call Python's distutils' or setuptools' setup() function in a slightly unconventional way, but I'm not sure whether distutils is meant for this kind of usage. As an example, let's say I currently have a 'setup.py' file, which looks like this (lifted verbatim from the distutils docs--the setuptools usage is almost identical): from distutils.core import setup setup(name='Distutils', version='1.0', description='Python Distribution Utilities', author='Greg Ward', author_email='[email protected]', url='http://www.python.org/sigs/distutils-sig/', packages=['distutils', 'distutils.command'], ) Normally, to build just the .spec file for an RPM of this module, I could run python setup.py bdist_rpm --spec-only, which parses the command line and calls the 'bdist_rpm' code to handle the RPM-specific stuff. The .spec file ends up in './dist'. How can I change my setup() invocation so that it runs the 'bdist_rpm' command with the '--spec-only' option, WITHOUT parsing command-line parameters? Can I pass the command name and options as parameters to setup()? Or can I manually construct a command line, and pass that as a parameter, instead? NOTE: I already know that I could call the script in a separate process, with an actual command line, using os.system() or the subprocess module or something similar. I'm trying to avoid using any kind of external command invocations. I'm looking specifically for a solution that runs setup() in the current interpreter. For background, I'm converting some release-management shell scripts into a single Python program. One of the tasks is running 'setup.py' to generate a .spec file for further pre-release testing. Running 'setup.py' as an external command, with its own command line options, seems like an awkward method, and it complicates the rest of the program. I feel like there may be a more Pythonic way.

• Why doesn't this simple regex match what I think it should?

  - by Kevin Stargel

  I have a data file that looks like the following example. I've added '%' in lieu of \t, the tab control character. 1234:56% Alice Worthington alicew% Jan 1, 2010 10:20:30 AM% Closed% Development Digg: Reddit: Update%% file-one.txt% 1.1% c:/foo/bar/quux Add%% file-two.txt% 2.5.2% c:/foo/bar/quux Remove%% file-three.txt% 3.4% c:/bar/quux Update%% file-four.txt% 4.6.5.3% c:/zzz ... many more records of the above form The records I'm interested in are the lines beginning with "Update", "Add", "Remove", and so on. I won't know what the lines begin with ahead of time, or how many lines precede them. I do know that they always begin with a string of letters followed by two tabs. So I wrote this regex: generate-report-for 1234:56 | egrep "^[[:alpha:]]+\t\t.+" But this matches zero lines. Where did I go wrong? Edit: I get the same results whether I use '...' or "..." for the egrep expression, so I'm not sure it's a shell thing.

• Starting a process in one HTTP call and getting results in another

  - by KillianDS

  Hi, I'm writing a very simple testing framework for my application, the design isn't perfect, but I don't have time to write something more complex. Essentially, I have a client and server-application, on my server I want a small python web server to start the server application with given test sequences on a GET or POST call. Also, the application prints some testdata to stderr which I'd like to catch and return in another HTTP call. At the moment I have this: from subprocess import Popen, PIPE from BaseHTTPServer import BaseHTTPRequestHandler, HTTPServer p = None class MyHandler(BaseHTTPRequestHandler): def do_GET(self): global p if self.path.endswith("start/"): p = Popen(["./bin/Release/simplex264","BBB-360","127.0.0.1"], stderr=PIPE) print 'started' return elif self.path.endswith("getResults/"): self.wfile.write(p.stderr.read()) return self.send_error(404,'File Not Found: %s' % self.path) def main(): try: server = HTTPServer(('localhost', 9876), MyHandler) print 'Started server...' server.serve_forever() except KeyboardInterrupt: print 'Shutting down...' server.socket.close() if __name__ == '__main__': main() Which 'works', except for one part, when I try to open http://localhost:9876/start/, it does not return before the process ended. However, the 'started' appears in my shell immediately (I added this because I thought the Popen call would only return after execution). I do not know the perfect inner workings of Popen and BaseHTTPRequestHandler however and do not really know where it goes wrong. Is there any way to make this work asynchronously?

• php, user-uploaded files, version control, and website deployment

  - by user151841

  I have a website that I regularly update the code to. I keep it in version control. When I want to deploy a new version of the site, I do an export and then symlink the served directory name to the directory of the deployment. There is a place where users can upload files, and I noticed once that, after I had deployed a new version, the user files were gone! Of course, I hadn't added them to the repository, and since the served site was from an export, they weren't uploaded into a version-controlled directory anyways. PHP doesn't yet have integrated svn functionality, so I couldn't do much programmatically to user uploaded files. My solution was to create an additional website, files.website.com, which sits in a parallel directory to the served website, and is served out of a directory that is under version control. That way they don't get obliterated when I do an upgrade to the website. From time to time, I manually add uploaded files to the svn project, deleted user-deleted ones, and commit the new version. I'm working on a shell script to run from cron to do this, but it isn't my forte, so it's on the backburner as it's not a pressing need. Is there a better way to do this?

• Access violations in strange places when using Windows file dialogs

  - by Robert Oschler

  A long time ago I found out that I was getting access violations in my code due to the use of the Delphi Open File and/or Save File dialogs, which encapsulate the Windows dialogs. I asked some questions on a few forums and I was told that it may have been due to the way some programs add hooks to the shell system that result in DLLs getting injected in every process, some of which can cause havoc with a program. For the record, the programming environment I use is Delphi 6 Professional running on Windows XP 32-bit. At the time I got around it by not using Delphi's Dialog components and instead calling straight into comdlg32.dll. This solved the problem wonderfully. Today I was working with memory mapped files for the first time and sure enough, access violations started cropping up in weird parts of the code. I tried my comdlg32.dll direct calls and this time it didn't help. To isolate the problem as a test I created a list box with the exact same files I was using during testing. These are the exact same test files I was selecting from an Open File dialog and then launching my memory mapped file with. I set things up so that by clicking on a file in the list box, I would use that file in my memory mapped file test instead of calling into a comdlg32.dll dialog function to select a test file. Again, the access violatons vanished. To show you how dramatic a fix it was I went from experiencing an access violation within 1 to 3 trials to none at all. Unfortunately, it's going to bite me later on of course when I do need to use file dialogs. Has anyone else dealt with this issue too and found the real culprit? Did any of you find a solution I could use to fix this problem instead of dancing around it like I am now? Thanks in advance.

• Processing command-line arguments in prefix notation in Python

  - by ejm

  I'm trying to parse a command-line in Python which looks like the following: $ ./command -o option1 arg1 -o option2 arg2 arg3 In other words, the command takes an unlimited number of arguments, and each argument may optionally be preceded with an -o option, which relates specifically to that argument. I think this is called a "prefix notation". In the Bourne shell I would do something like the following: while test -n "$1" do if test "$1" = '-o' then option="$2" shift 2 fi # Work with $1 (the argument) and $option (the option) # ... shift done Looking around at the Bash tutorials, etc. this seems to be the accepted idiom, so I'm guessing Bash is optimized to work with command-line arguments this way. Trying to implement this pattern in Python, my first guess was to use pop(), as this is basically a stack operation. But I'm guessing this won't work as well on Python because the list of arguments in sys.argv is in the wrong order and would have to be processed like a queue (i.e. pop from the left). I've read that lists are not optimized for use as queues in Python. So, my ideas are: convert argv to a collections.deque and use popleft(), reverse argv using reverse() and use pop(), or maybe just work with the int list indices themselves. Does anyone know of a better way to do this, otherwise which of my ideas would be best-practise in Python?

• How to minor updates to Drupal-6 with shared hosting

  - by marty.fried

  I've got Drupal working on a shared host, and I uploaded some modules from my home system successfully, but I've got the message that there is a security update for my version, and I should update immediately. I'm not sure how I'm supposed to do that. It seems like the update is an entire new installation. I originally installed it using the hosting company's installer, Fantastico. Should I simply over-write the existing installation with the new files? Or ignore the message? I realize I shouldn't over-write the sites folder, or anything I've modified. The instructions that come with the download seem to be for a major version upgrade, and are way too much trouble for frequent security updates. Searching Drupal's site shows many other methods, but no indication of anything official. And some were ridiculously error-prone, and not really useful. I don't have shell access to the hosting site, although I can pay extra to get it if I really need to. Or, maybe I can clone the site on my local Linux system, do the update using a script, then upload the whole thing. Does anyone have experience with this situation?

• Is there a way to easily convert a series of tarballs of a source tree into a git repository?

  - by Hotei

  I'm new to git and I have a moderately large number of weekly tarballs from a long running project. Each tarball has on average a few hundred files in it. I'm looking for a git strategy that will allow me to add the expanded contents of each tarball to a new git repository, starting from version 1.001 and going through version 1.650. As of this stage of the project 99.5% of tarball(n) is just a copy of version(n-1) - in other words, a perfect candidate for git. The desired end result is to have only the master branch remaining at the end of the process. I think I know git well enough to do this "by hand". As I understand it there is no possibility of a merge conflict since there will be no opportunity to change the master before the next version is added and committed. A shell script is my first guess, but I'm not sure how well bash will like it when git checkout branch_n gets processed while bash is executing in branch_n-1. For the purposes of this project the host environment is Ubuntu 10.4, resources available are 8 Gig RAM, 500 Gig Disk space free and 4 CPU processor at 3.ghz . I don't need someone else to solve the problem but I could use a nudge in the right direction as to how a git expert would approach it. Any advice from someone who's "been there done that" would be appreciated. Hotei PS: I have looked at site's suggested "related questions" and found nothing relevant.

• How can I automatically elevate a COM interface used for automation?

  - by Jim Flood

  I have a Windows service built with ATL to expose a LocalServer32 COM interface for a set of admin commands used for configuring the service, and these can be used from VBScript for example: Set myObj = WScript.CreateObject("MySvc.Administrator") myObj.DoSomething() I want DoSomething to run elevated, and I would like the UAC prompt to come up automatically when this is called by the VBScript. Is this possible? I know I can run the script in an elevated command shell, and that I can use objShell.ShellExecute WScript.FullName, Chr(34) & WScript.ScriptFullName & Chr(34), vbNullString, "runas" for example, to run the VBScript itself elevated, and either of those work fine -- the COM method finds itself elevated. However, AFAIK getting an elevated Explorer window on the desktop is convoluted (it's not as simple as right-clicking Start/Accessories/Windows Explorer/Run as Administrator, which doesn't actually elevate.) I want a user in the local admin group to be able to drag-and-drop files and folders onto the script, and then have the script call the admin COM interface with those pathnames as arguments. (And I am hoping for something simpler than monkeying around with the args and using ShellExecute "runas".) I've tried setting UAC Execution Level to requireAdministrator in the service EXE's manifest, and setting Elevated/Enabled = 1 and LocalizedString in the registry for the MySvc.Administrator class, and these don't do the trick.

On each TabItem i crate a Composite and set the TabItem.setControl() to the Composite. I then use this Composite as the page on which i draw my items. I draw a set of Controls, including Textbox's and Labels. For the First, Default Tab, this works fine. No problems. Problem On tabs that is not the first tab i have the following problems: I am unable to visually alter then Edited/Enabled state of my Controls. I am unable to visually set the Text content of my elements My Controls look disabled and have a Greyed out look. But i am able to Select the content with my mouse and use CTRL+C to copy it out. So the text contet is there and they are Editable. Visually it is just not updated. Any comments are appeciated, Any requests for code, examples will be supplied and help Welcommed. Updates I tried added the suggest debug loop to the code, where i attempt to enable my Controls. This was the result: [main] INFO [dk.viking.controller.LayerController] - f038.stklok is now Editable [true] and enabled [true] [main] INFO [dk.viking.controller.LayerController] - true Text {} [main] INFO [dk.viking.controller.LayerController] - true Composite {} [main] INFO [dk.viking.controller.LayerController] - true TabFolder {} [main] INFO [dk.viking.controller.LayerController] - true Shell {Viking GUI}

• JSF: Avoid nested update calls

  - by dhroove

  I don't know if I am on right track or not still asking this question. I my JSF project I have this tree structure: <p:tree id="resourcesTree" value="#{someBean.root}" var="node" selectionMode="single" styleClass="no-border" selection="#{someBean.selectedNode}" dynamic="true"> <p:ajax listener="#{someBean.onNodeSelect}" update=":centerPanel :tableForm :tabForm" event="select" onstart="statusDialog.show();" oncomplete="statusDialog.hide();" /> <p:treeNode id="resourcesTreeNode" > <h:outputText value="#{node}" id="lblNode" /> </p:treeNode> </p:tree> I have to update this tree after I added something or delete something.. But whenever I update this still its nested update also call I mean to say it also call to update these components ":centerPanel :tableForm :tabForm"... This give me error that :tableForm not found in view because this forms load in my central panel and this tree is in my right panel.. So when I am doing some operation on tree is it not always that :tableForm is in my central panel.. (I mean design is something like this only) So now my question is that can I put some condition or there is any way so that I can specify when to update nested components also and when not.... In nut shell is there any way to update only :resoucesTree is such a way that nested updates are not called so that I can avoid error... Thanks in advance.

• Magic function `bash ` not found

  - by inspectorG4dget

  I have a bunch of simulations that I want to run on a high-performance cluster, on which I should make reservations to get computing time. Since the reservations are bounded by time, I am developing an automation script that I can scp into the cluster and run. This script will then download the relevant simulation files, run them, and upload the results. Part of this automation script is in bash (cp, scp, etc) and the rest is in python. In order to develop this automation, I am using an IPython notebook. So far, I've coded all the python automation stuff in my IPython notebook and am trying to write the bash part of it now. However, it seems that the magic %%bash doesn't work in my IPython notebook. I get the following error when I have this code in my cell: Cell %%bash echo hi Error File "<ipython-input-22-62ec98e35224>", line 3 echo hi ^ SyntaxError: invalid syntax On a whim, I tried this: Cell %%bash print "hi" Error hi ERROR: Magic function `bash` not found. So I tried this with %%system, %%! and %%shell. But none of those work; they all give me the same error. Why is this happening? How can I fix this?

• Android, how to use DexClassLoader to dynamically replace an Activity or Service

  - by RickNotFred

  I am trying to do something similar to this stackoverflow posting. What I want to do is to read the definition of an activity or service from the SD card. To avoid manifest permission issues, I create a shell version of this activity in the .apk, but try to replace it with an activity of the same name residing on the SD card at run time. Unfortunately, I am able to load the activity class definition from the SD card using DexClassLoader, but the original class definition is the one that is executed. Is there a way to specify that the new class definition replaces the old one, or any suggestions on avoiding the manifest permission issues without actually providing the needed activity in the package? The code sample: ClassLoader cl = new DexClassLoader("/sdcard/mypath/My.apk", getFilesDir().getAbsolutePath(), null, MainActivity.class.getClassLoader()); try { Class<?> c = cl.loadClass("com.android.my.path.to.a.loaded.activity"); Intent i = new Intent(getBaseContext(), c); startActivity(i); } catch (Exception e) { Intead of launching the com.android.my.path.to.a.loaded.activity specified in /sdcard/mypath/My.apk, it launches the activity statically loaded into the project.
