  • How do I get the WVGA Android browser to stop scaling my images?

    - by Dan Fabulich
    I'm designing an HTML page for display in Android browsers. Consider this simple example page: <html> <head><title>Simple!</title> </head> <body> <p><img src="http://sstatic.net/so/img/logo.png"></p> </body> </html> It looks just fine on the standard HVGA phones (320x480), but on HDPI WVGA sizes (480x800 or 480x854) the built-in browser automatically scales the image up; it looks ugly. I've read that I should be able to use this tag to force the browser to stop scaling my page: <meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0; minimum-scale=1.0; user-scalable=0;" /> ... but all that does is disable user scaling (the zoom buttons disappear); it doesn't actually prevent the browser from scaling my image. Adjusting the scale factors (setting them all to 2.0 or 0.5) has no effect at all. How can I force the WVGA browser to stop scaling my images?

  • Why do I get an error while trying to set the content of a tabspec in android?

    - by rushinge
    I have an android activity in which I'm using tabs. public class UnitActivity extends TabActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.unit_view); TabHost tabHost = getTabHost(); TabSpec spec; spec = tabHost.newTabSpec("controls"); spec.setIndicator("Control"); spec.setContent(R.layout.unit_control); tabHost.addTab(spec); spec = tabHost.newTabSpec("data"); spec.setIndicator("Data"); spec.setContent(R.layout.unit_data); tabHost.addTab(spec); } } However when I run the program it crashes with the error: "Could not create tab content because could not find view with id 2130903042". I don't understand what the problem is because R.layout.unit_data refers to a layout file in my resource directory (res/layout/unit_data.xml) as far as I can tell unit_data.xml is well formed and I've even referenced it successfully in another activity class UnitData extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.unit_data); Toast.makeText(this, "Hi from UnitData.onCreate", 5); } } which does not give an error and renders the layout just fine. What's going on? Why can't I reference this layout when creating a tab?

  • Why does my Android App crash when loading image from gallery the 2nd time?

    - by Sebastian
    Hi folks, I've written an app, thats loading images either using the android gallery app or by taking a photo using the cam. When I now load an image using the gallery, everything is fine. When the code is being executed a second time (for loading another image), the application crashes. try { Uri data = intent.getData(); ContentResolver cr = this.getContentResolver(); Bitmap mBitmap = null; mBitmap = Media.getBitmap(cr, data); imageView.setImageBitmap(mBitmap); } catch(Exception e){ showToast(this, "Failed loading image from gallery"); return; } The code crashes at the line mBimap = Media.getBitmap(cr, data);. Everything is initialized, there are no null values etc. The strange thing is: no exception is thrown, I don't get into the catch block to determine whats going wrong. Does anyone have an idea about this? Am I not allowed to "re-use" the content resolver? Do I have to free it after the first usage or something like this?

  • iPhone or Android apps that use SMS based authentication?

    - by JSW
    What are some iPhone or Android applications that use SMS as their primary means of user authentication? I'm interested to see such apps in action. SMS-auth seems like a natural approach that is well-situated to mobile contexts. The basic workflow is: to sign up, a user provides a phone number; the app calls a backend webservice which generates a signed URL and sends it to the phone number via an SMS gateway; the user receives the SMS, clicks the link, and is thus verified and logged in. This results in a very strong user identity that is difficult to spoof yet fairly easy. It can be paired with a username or additional account attributes as needed for the product requirements. Despite the advantages, this does not seem to be in much use - hence my question. My initial assumption is that this is because products and users are wary of asking for / providing phone numbers, which users consider sensitive information. That said, I hope this becomes an increasingly more commonplace approach.

  • How to easily Generate Synth Chords Sounds in Android?

    - by barata7
    How to easily Generate Synth Chords Sounds in Android? I wanna be able to generate dynamically an in game Music using 8bit. Tried with AudioTrack, but did not get good results of nice sounds yet. Any examples out there? I have tried the following code without success: public class BitLoose { private final int duration = 1; // seconds private final int sampleRate = 4200; private final int numSamples = duration * sampleRate; private final double sample[] = new double[numSamples]; final AudioTrack audioTrack; public BitLoose() { audioTrack = new AudioTrack(AudioManager.STREAM_MUSIC, sampleRate, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_8BIT, numSamples, AudioTrack.MODE_STREAM); audioTrack.play(); } public void addTone(final int freqOfTone) { // fill out the array for (int i = 0; i < numSamples; ++i) { sample[i] = Math.sin(2 * Math.PI * i / (sampleRate / freqOfTone)); } // convert to 16 bit pcm sound array // assumes the sample buffer is normalised. final byte generatedSnd[] = new byte[numSamples]; int idx = 0; for (final double dVal : sample) { // scale to maximum amplitude final short val = (short) ((((dVal * 255))) % 255); // in 16 bit wav PCM, first byte is the low order byte generatedSnd[idx++] = (byte) (val); } audioTrack.write(generatedSnd, 0, sampleRate); } public void stop() { audioTrack.stop(); }

  • Is it possible to pull a webpage or content from the web into a widget on the android home screen

    - by cdg
    Hi there. I have a php web page that will randomize an image that is 158x154. I was able to get the android application to work, but would also like to get it to work as a widget. How the heck can I get a widget to pull information from the net? I got the widget to work and layout correctly with a black sample image. I have tried to look at the wiki sample, but it is a bit too complicated for my little brain to grasp. The data that gets pulled looks something like: <html><body bgcolor="#000000">center> <a href="http://www.website.com" target="_blank"> <img border="0" src="http://www.webiste.com//0.gif"></a> <img src="http://www.webiste.com" style="border:none;" /> </center></body></html> Help please. I am pulling my hair out trying to figure this out.

  • How to find a particular string in a paragraph in android?

    - by user1448108
    In my project the data is stored in html format along with image tag. For example the following data is stored in html format and it contains 2 to 3 images. Mother Teresa as she is commonly known, was born Agnes Gonxha Bojaxhiu. Although born on the 26 August 1910, she considered 27 August, the day she was baptized, to be her "true birthday". “By blood, I am Albanian. By citizenship, an Indian. By faith, I am a Catholic nun. As to my calling, I belong to the world. As to my heart, I belong entirely to the Heart of Jesus." img ----- src="image1.png" ---- Mother Teresa founded the Missionaries of Charity, a Roman Catholic religious congregation, which in 2012 consisted of over 4,500 sisters and is active in 133 countries.img ----- src="image2.png" ----. She was the recipient of numerous honours including the 1979 Nobel Peace Prize. She refused the conventional ceremonial banquet given to laureates, and asked that the $192,000 funds be given to the poor in India. img ----- src="image3.png" ---- Now from the above data I need to find how many images the paragraph has and need to get all the image names along with the extensions and should display them in android. Tried with splitting but did not work. Please help me regarding this. Thanks in advance

  • Why does my SQL database not work in Android?

    - by user1426967
    In my app a click on an image button brings you to the gallery. After clicking on an image I want to call onActivityResult to store the image path. But it does not work. In my LogCat it always tells me that it crashes when it tries to save the image path. Can you find the problem? My onActivityResult method: mImageRowId = savedInstanceState != null ? savedInstanceState.getLong(ImageAdapter.KEY_ROWID) : null; @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if(requestCode == PICK_FROM_FILE && data != null && data.getData() != null) { Uri uri = data.getData(); if(uri != null) { Cursor cursor = getContentResolver().query(uri, new String[] { android.provider.MediaStore.Images.ImageColumns.DATA}, null, null, null); cursor.moveToFirst(); String image = cursor.getString(0); cursor.close(); if(image != null) { // HERE IS WHERE I WANT TO SAVE THE IMAGE. HERE MUST BE THE ERROR! if (mImageRowId == null) { long id = mImageHelper.createImage(image); if (id > 0) { mImageRowId = id; } } // Set the image and display it in the edit activity Bitmap bitmap = BitmapFactory.decodeFile(image); mImageButton.setImageBitmap(bitmap); } } } } This is my onSaveInstanceState method: private static final Long DEF_ROW_ID = 0L; @Override protected void onSaveInstanceState(Bundle outState) { outState.putLong(ImageAdapter.KEY_ROWID, mImageRowId != null ? mImageRowId : DEF_ROW_ID); super.onSaveInstanceState(outState); } This is a part from my DbAdapter: public long createImage(String image) { ContentValues cv = new ContentValues(); cv.put(KEY_IMAGE, image); return mImageDb.insert(DATABASE_TABLE, null, cv); }

  • SCOM 2007 versus Zenoss (or other open source)

    - by TheCleaner
    I've taken the liberty to test both SCOM 2007 and Zenoss and found the following: SCOM 2007 Pros: Great MS Windows server monitoring and reporting In-depth configuration and easily integrates into a "MS datacenter" Cons: limited network device monitoring support (without 3rd party plugins) expensive difficult learning curve Zenoss Pros: Open Source (free) decent server monitoring for Windows, great monitoring for Linux decent network device monitoring Cons: not as in-depth as SCOM (for Windows at least) So my question to you folks is this: Given the above, and given that I'm trying to monitor 55 Windows servers, 1 Linux server, 2 ESX servers, and Juniper equipment...which would you recommend?

  • Installing the Newest KeePass for MacOSX from Source

    - by firebush
    I've transitioned our passwords to KeePass. LastPass looks cool, but I prefer a system where we control the database locally rather than it being kept in the cloud. I have a windows and Linux system and both are able to access our KeePass database easily. On my Linux system (Ubuntu), I simply installed KeePass via synaptic and it just worked. So everything was working great, until my wife tried to set up things on her MacBook to access the database. Huge problems. It was so easy on Linux that I didn't expect there to be issues there. In case it's helpful, she's running a fresh install of Mac OSX 10.5.8, Leopard. We simply went to the download site for KeePass: http://keepass.info/download.html Clicked on the link titled KeePass 2.x for Mac OS X from which we retrieved Mono 2.10.5 and KeePass 2.18 from that site (the packages posted there at the time of this writing). Mono installed without problems (at least, none that we saw). She opened the KeePass image and dragged it to the Application side, unpackaging it there. According to the instructions on the KeePass installation instructions, she opened a terminal, changed to the directory in /Applications containing KeePass.exe, and ran it through mono: mono KeePass.exe No application opens at all - we see a blip for it, but then it immediately goes away, indicating to us that it is crashing. Also disconcerting, I see that people are throwing fits about copy-and-paste not working for KeePass 2.18 on MacOSX. Judging from the 2.19 addresses the copy/paste issue. I'm hoping that version will solve all our issues. So here's my question: how can I try out 2.19 on her system. It doesn't seem to be packaged like the 2.18 one is. But we're not scared of building it. I see that the source for 2.19 is here (at the bottom of the page). Can I just download that to her machine somewhere and run something to build it? I'm familiar with automake but not with building .NET source, so please answer gently if this is stupidly easy. :^) btw: tomorrow's my wife's birthday, and this is getting her down. If you know how to navigate these issues, it would be a nice birthday gift for her. Thanks in advance! Update I'll post this since it might be helpful to someone else: I got KeePass 2.18 to run by updating Mono to 2.10.9 (rather than the 2.10.5 given by the site above). With the later version of Mono, it runs without crashing. And yet, I do see the copy and paste issue that others see. I can open a database on her machine, but the incorrect data get's copied. So again, can someone help me install KeePass 2.19? Thanks!

  • Freeware (preferably open-source) tool for creating multi-file spanning archives as a self merging SFX

    - by Lockszmith
    I have a large file I want to transfer using either Internet storage hosting, DVD-Rs or USB storage, which sometimes is limited to FAT file-systems (for example: mobile phones) What I'm basically looking for is a tool that create multiple files/volumes (less than 2GB each - FAT's file size limit) which are packed with a self-extracting executable. Currently the only tool I found doing this is WinRAR, but that's shareware, and not free. Is there any Free, preferably Open-Source tool that does that? Thank in advance

  • Keep source IP after NAT

    - by John Miller
    Until today I used a cheapy router so I can share my internet connection and keep a webserver online too, while using NAT. Users IP ($_SERVER['REMOTE_ADDR']) was fine, I was seeing class A IPs of users. But as traffic grown up everyday, I had to install a Linux Server (Debian) to share my Internet Connection, because my old router couldn't keep the traffic anymore. I shared the internet via IPTABLES using NAT, but now, after forwarding port 80 to my webserver, now instead of seeing real users IP, I see my Gateway IP (Linux Internal IP) as any user IP Address. How to solve this issue? I edited my post, so I can paste the rules I'm currently using. #!/bin/sh #I made a script to set the rules #I flush everything here. iptables --flush iptables --table nat --flush iptables --delete-chain iptables --table nat --delete-chain iptables -F iptables -X # I drop everything as a general rule, but this is disabled under testing # iptables -P INPUT DROP # iptables -P OUTPUT DROP # these are the loopback rules iptables -A INPUT -i lo -j ACCEPT iptables -A OUTPUT -o lo -j ACCEPT # here I set the SSH port rules, so I can connect to my server iptables -A INPUT -p tcp --sport 513:65535 --dport 22 -m state --state NEW,ESTABLISHED -j ACCEPT iptables -A OUTPUT -p tcp --sport 22 --dport 513:65535 -m state --state ESTABLISHED -j ACCEPT # These are the forwards for 80 port iptables -t nat -A PREROUTING -p tcp -s 0/0 -d xx.xx.xx.xx --dport 80 -j DNAT --to 192.168.42.3:80 iptables -t nat -A POSTROUTING -o eth0 -d xx.xx.xx.xx -j SNAT --to-source 192.168.42.3 iptables -A FORWARD -p tcp -s 192.168.42.3 --sport 80 -j ACCEPT # These are the forwards for bind/dns iptables -t nat -A PREROUTING -p udp -s 0/0 -d xx.xx.xx.xx --dport 53 -j DNAT --to 192.168.42.3:53 iptables -t nat -A POSTROUTING -o eth0 -d xx.xx.xx.xx -j SNAT --to-source 192.168.42.3 iptables -A FORWARD -p udp -s 192.168.42.3 --sport 53 -j ACCEPT # And these are the rules so I can share my internet connection iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE iptables -A FORWARD -i eth0:1 -j ACCEPT If I delete the MASQUERADE part, I see my real IP while echoing it with PHP, but I don't have internet. How to do, to have internet and see my real IP while ports are forwarded too? ** xx.xx.xx.xx - is my public IP. I hid it for security reasons.
