  • Is it possible to start an activity in a different apk using startActivity on Android using the acti

    - by icecream
    I have tried to write an Android application with an activity that should be launched from a different application. It is not a content provider, just an app with a gui that should not be listed among the installed applications. I have tried the code examples here and it seems to be quite easy to launch existing providers and so on, but I fail to figure out how to just write a "hidden" app and launch it from a different one. The basic use case is: App A is a normal apk launchable from the application list. App B is a different apk with known package and activity names, but is is not visible or launchable from the application list. App A launches app B using the package and class names (or perhaps a URI constructed from these?). I fail in the third step. Is it possible to do this?

  • Where are graphically pleasing examples of Lists

    - by slim
    Anyone know of good code examples of how to make lists look different than your everyday average black list or more graphically pleasing than you usually see in android apps. I've looked through google code but haven't found too many. I'm looking for different and eye catching lists. I hope this question isn't too generic. Also i'm open to anything, code, examples, blog posts, etc, you name it. I've really struggled with lists and making them look more snazzy. I'm talking more the code level not the graphics or icons used.

  • Keyboard problem on iPhone OS 4.0 (8A248c)

    - by Newbee
    Hi! I have view with text field -- subclassed from UIAlertView. In the textFieldShouldReturn delegate I call resignFirstResponder for text field and dismissWithClickedButtonIndex for view. On the 3.x version everything fine, but on 4.0 keyboard still present on screen after view dismissing and doesn't disappear while app running. App compiled for 3.0 target and tested on 4.0 iPhone OS. One more thing - sometimes after dismissing alert - Done button on the keyboard replaces with Return button.. Any suggestions ?

    - by Denis Hoss
    From today, when I tried to run an app in NetBeans on a 2.3.3 Android platform, it shows me that: Failed to allocate memory: 8 This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. and the Emulator doesn't want to start. This is for the first time when I see it, and google has no asnwers for this, I tried even with 2 versions of NetBeans 6.9.1 and 7.0.1, still the same error.

  • Android remote code loading

    - by sehugg
    I am developing a library for Android that requires frequent updates from a central server. I was thinking how nice it would be if my library could update itself -- or if I could just release a bootstrap library that downloads the target library when the app is installed. I see this class in 1.5 called "DexClassLoader" but there seems to be precious little on the web besides the API docs. Has anyone used this successfully for the scenario which I described? Also, do the terms of the Android Market permit such a thing?

  • Pushing View from UITableView Problem

    - by golfromeo
    Basically, what I want is to be able to press a record in a table, and have it push to another view. To do this, I created a nib file and a UIViewController subclass (for the "pushed" view). I set the nib file's "File Owner" to be the controller I created. Then, in the view controller of the table that will push that view, I set the didSelectRowIndexAtPath: method to include the following: SearchTableController *vc = [[SearchTableController alloc] initWithNibName:@"SearchTable" bundle:[NSBundle mainBundle]]; [self.navigationController pushViewController:vc animated:YES]; [vc release]; (where "SearchTableController" is the name of the UIViewController subclass and "SearchTable" is the name of the nib file) However, when I run this code and click on the record, nothing happens- the app doesn't crash, but the view doesn't get pushed. The code is getting run, because it works when I NSLog(), but it doesn't seem to be pushing the view. Thanks for any help in advance.

  • How to tell if a user updated my app or installed a new one

    - by user310318
    I need a way to tell if the app being used by a user is a fresh new install (new user), or was a pre-existing user who updated. The previous app version did not track UDID's, and didn't save anything (it just ran as a simple app). Is there a way for an update to tell if the user previously installed the app? Even if that app didn't save anything into the documents folder, and the app didnt communicate with a server (UDID post)? (id like to be able to offer bonus features to my existing loyal users who had already installed the original app and updated) thanks!!

  • Core Data NSFetchedResultsController sorting in certain sequence

    - by Moze
    I'm writing iphone app that has UITableView and uses Core Data. Data in UITableView is shown using NSFetchedResultsController. I use NSPredicate operator "IN" to fetch only needed entries. NSArray *filterArray = [NSArray arrayWithObjects:@"789", @"963", @"445", @"198", nil]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"id IN %@", filterArray]; Now the problem is that I need to show entries in same sequence they are in filterArray. How can I do it? How I can create NSSortDescriptor that would sort all entries in that way? I tried without sort descriptor, but I get error that NSFetchedResultsController needs sortDescriptor to be set.

  • iphone: Implement delegate in class

    - by Nic Hubbard
    I am trying to call up a modal table view controller using presentModalViewController but I am not sure what to do about the delegate. The following code gives me an error: MyRidesListView *controller = [[MyRidesListView alloc] init]; controller.delegate = self; [self presentModalViewController:controller animated:YES]; [controller release]; Error: Request for member 'delegate' is something not a structure or union Now, I realized there is no delegate property in my MyRidesListView class. So, how would I add a reference to my delegate there? What am I missing here?

  • Finding user location before map loads

    - by 4thSpace
    I'm trying to find the user's location using: CLLocationCoordinate2D _location; CLLocation *userLoc = nil; if(appDelegate.clLocationManager.locationServicesEnabled){ userLoc = mapView.userLocation.location; _location = userLoc.coordinate; } The problem is that I haven't yet initialized the map so the above doesn't work. Is there a way to get the user's location without using mapkit? Or should I be using a different technique?

  • Google Doclist API : bug in revision history?

    - by Jerbome
    I'm trying to manage revisions of files (not documents) stored in google docs programatically using gdata document list java library v3. I can create files and revisions using this tool : I can see them in the web UI. The thing is : the content of my revisions seems wrong. Here is my test protocol : I create a plain text file with "Hello World" in it. I upload it to gdocs without converting it. I create a revision of this file, its content changing to "Content of the second version" I create another revision, its content is now "Content of the third version" At each step, I check the content of each revision, using my app AND using the web UI. Here is what I get : First step : no problem i see one version containing the "Hello world" text Second step : no problem either, i see 2 versions, containing Hello World for the first one and Content of the second version for the second. Third step : here the problems comes. I see my 3 versions, but only the third and last seems to be correct. when i download the second version, the content is "Content of the second versio" (not a typo, it misses the 'n'). And i cannot even download the initial version, it seems to timeout. Important thing : I did not have this problem three weeks ago, my revision management worked well. I have no idea of what happens there, except it seems to be server-related, as the problem is seen either with my app or the google native webapp. Last thing : I tried using the google drive API as gdocs had been merged with drive. When i request revisions of my file, the API returns me an error saying that revisions are not supported for files, even if i can see them in the UI. I tried on converted documents, it worked. I'm looking for a workaround for this problem. Has anyone ever encountered such a problem ? Thanks in advance, Jérôme

  • Conditional interface programming for iPad?

    - by Fyrian
    Hi everyone! I'm working on an app for the iPad and am a little over my head with one issue. Is it possible to build an app for iPad that uses a function to control which interface layout is displayed? Something like "if these parameters are met, use XIB file "a" else use XIB file "b". I know that's not in any kind of legitimate format, but you get the idea. If this is possible, does anyone know of any tutorials on how to do it or sample code I could look at? Thanks!

  • inputAccessoryView not hide the view when -resignFirstResponder?

    - by Sam Jarman
    I have attached a toolbar with a UITextField and UIButton to the keyboard when it becomes the first responder via the user taping inside the textfield textField.inputAccessoryView = theToolbar; Problem is, the toolbar disappears when the keyboard is dismissed, thus preventing any further input. Any ideas on how to make the toolbar go back to the bottom of the screen rather than off it completely? I'm thinking a delegate method might help but Im really not too sure. It seems once the inputAccessoryView always the inputAccessoryView :( Cheers

  • iPhone UIImage number recognition

    - by Skeep
    Hi All, I have a small UIImage (jpg) with a single typed number. I want to be able to read the number with some kind of pattern recognition. I'm really not sure where to start, so any help would be appreciated. my initial idea was to compare this image with other images. For instance compare the image with that of a 1,2,3, etc until a match was found. That just seems slow and cumbersome and wondered if there was a better way to do it? Thanks
