• wsimport and Android or any other ProxyGenerator for android?

  - by Shoaib Shaikh

  I am currently developing an Android app i previously developed for IPhone. My Backend is built using WCF service with basichttpEndpoint, i also enabled RESTful methods for better support with other Mobile platforms as well. Now i want to access my existing WCF service(SOAP/REST endpoint) on Android but i need some good ProxyGenerator to consume my services. I just google around for some solution and i found wsimport and wsdl2java(Axis) are two options in java domain. But i am still unable to find any solution related to Android. Can anyone suggest me the best practice in such scenario?

• Insert new relationship data in core data

  - by michael

  Hoping someone can shed some light on what I might be doing wrong here. Trying to add an "event" to a list of events, represented by a one to many (inverse) relationship: MyEvents <--- Event This is the code: MyEvents *myEvents = (MyEvents *)[NSEntityDescription insertNewObjectForEntityForName:@"MyEvents" inManagedObjectContext:context]; NSLog(@"MYEVENTS: %@", myEvents); NSLog(@"EVENT: %@", event); [myEvents addEventObject:event]; My context is fine, and both the myEvents and event print perfectly valid information. When I try to add the event that I have (which is passed into this view controller, having been retrieved from core data previously) with this code [myEvents addEventObject:event]; It falls over with *** -[NSComparisonPredicate evaluateWithObject:]: message sent to deallocated instance MyEvents and Event are just the default generated code. MyEvents contains only the relationship to event. Thanks.

• XCode 3.2 does not mark unit test assert failures in the editor

  - by Cliff

  I've been off in Java land for about a month or so and now, upon returning to XCode I feel lost. I've upgraded 1st to 3.1.2 then recently to 3.2 and also got a new Mac with Snow Leopard so I'm not exactly sure when the problem surfaced. I just know that I used to get little red bubbles in my unit test next to the failing asserts and that no longer seems to happen. Is there a way to restore this? I've been trying to use Apple's own SenTesting framework instead of GoogleTools for mac like I used to. Should I revert to Google Tools? Does anyone have an answer?

• Architecting iPhone Views - seeking help on a specific issue + general advice

  - by Ev

  Hi there, I am a web developer (rails, python) that is new to iPhone development. I've done some desktop development in the past within the MS environment (C#). I'm trying to build a really simple iPhone application and I am confused by the way that views work in general. If someone can provide advice for my particular problem, along with some resources where I can learn how to architect iPhone views in the future, that would be awesome. I feel like a lot of the Apple documentation that I've come across is too specific - I am lacking a fundamental understanding of how views work on the iPhone. My particular problem looks like this: I need one view that displays some downloaded text content. This is the view that shows when the app loads, and it is pretty straightforward. Then I need a settings area (I've already decided I don't want to use the iPhone settings area). The settings area main page will have some text fields on it. It will also have a 2-row grouped table. Each cell in that table will take you to another view which also has a grouped table used for multi-select. I suspect that I can reuse the same view for these two final "detailed setting" views. In summary: home page settings main page detailed setting 1 detailed setting 2 Any help and advice appreciated.

• How to debug EXC_BAD_ACCESS that occurs only on release target for an iPhone app?

  - by Bobby Moretti

  I'm developing an iPhone application. I have an EXC_BAD_ACCESS that occurs only in the release target; when I build the debug target the exception does not occur. However, when I set the NSZombieEnabled environment variable to YES, I still get the EXC_BAD_ACCESS with no further information. Is it even possible for NSZombieEnabled to work when executing the release target? I don't see why not, since gdb is running in both cases...

• custom button: properties change, button should be redrawn

  - by Rutger

  Hi I'm developing an Android app. I have class derived from button to represent a special type of button. This special type has some properties (integers) and according to these one or more circles have to be drawn on top of the button. So I overrode the onDraw function, which looks the values up and accordingly draws the circles. But the class has a function to set new values for its properties. So new values are set but the changes are not reflected in the UI. It seems like the onDraw function is not called. When later I click the button or show a pop up message above my interface the onDraw function is called and the button is drawn correctly. So my question: when changing the properties how can I say that the button has to be redrawn? Thanks a lot!

• How do I handle calls to AudioTrack from jni without crashing?

  - by icecream

  I was trying to write to an AudioTrack from a jni callback, and I get a signal 7 (SIGBUS), fault addr 00000000. I have looked at the Wolf3D example for odroid and they seem to use a android.os.Handler to post a Runnable that will do an update in the correct thread context. I have also tried AttachCurrentThread, but I fail in this case also. It works to play the sound when running from the constructor even if I wrap it in a thread and then post it to the handler. When I do the "same" via a callback from jni it fails. I assume I am braeaking some rules, but I haven't been able to figure out what they are. So far, I haven't found the answer here on SO. So I wonder if anyone knows how this should be done. EDIT: Answered below. The following code is to illustrate the problem. Java: package com.example.jniaudiotrack; import android.app.Activity; import android.media.AudioFormat; import android.media.AudioManager; import android.media.AudioTrack; import android.os.Bundle; import android.os.Handler; import android.util.Log; public class JniAudioTrackActivity extends Activity { AudioTrack mAudioTrack; byte[] mArr; public static final Handler mHandler = new Handler(); /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mArr = new byte[2048]; for (int i = 0; i < 2048; i++) { mArr[i] = (byte) (Math.sin(i) * 128); } mAudioTrack = new AudioTrack(AudioManager.STREAM_MUSIC, 11025, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_8BIT, 2048, AudioTrack.MODE_STREAM); mAudioTrack.play(); new Thread(new Runnable() { public void run() { mHandler.post(new Runnable() { public void run() { mAudioTrack.write(mArr, 0, 2048); Log.i(TAG, "*** Handler from constructor ***"); } }); } }).start(); new Thread(new Runnable() { public void run() { audioFunc(); } }).start(); } public native void audioFunc(); @SuppressWarnings("unused") private void audioCB() { mHandler.post(new Runnable() { public void run() { mAudioTrack.write(mArr, 0, 2048); Log.i(TAG, "*** audioCB called ***"); } }); } private static final String TAG = "JniAudioTrackActivity"; static { System.loadLibrary("jni_audiotrack"); } } cpp: #include <jni.h> extern "C" { JNIEXPORT void Java_com_example_jniaudiotrack_JniAudioTrackActivity_audioFunc(JNIEnv* env, jobject obj); } JNIEXPORT void Java_com_example_jniaudiotrack_JniAudioTrackActivity_audioFunc(JNIEnv* env, jobject obj) { JNIEnv* jniEnv; JavaVM* vm; env->GetJavaVM(&vm); vm->AttachCurrentThread(&jniEnv, 0); jclass cls = env->GetObjectClass(obj); jmethodID audioCBID = env->GetMethodID(cls, "audioCB", "()V"); if (!audioCBID) { return; } env->CallVoidMethod(cls, audioCBID); } Trace snippet: I/DEBUG ( 1653): pid: 9811, tid: 9811 >>> com.example.jniaudiotrack <<< I/DEBUG ( 1653): signal 7 (SIGBUS), fault addr 00000000 I/DEBUG ( 1653): r0 00000800 r1 00000026 r2 00000001 r3 00000000 I/DEBUG ( 1653): r4 42385726 r5 41049e54 r6 bee25570 r7 ad00e540 I/DEBUG ( 1653): r8 000040f8 r9 41048200 10 41049e44 fp 00000000 I/DEBUG ( 1653): ip 000000f8 sp bee25530 lr ad02dbb5 pc ad012358 cpsr 20000010 I/DEBUG ( 1653): #00 pc 00012358 /system/lib/libdvm.so

• How to save video from a url to disk, also how to begin playback after some buffering?

  - by Shizam

  First question is, given a url to an mp4 video, how can I save that file to disk? The followup to that is while its saving, can I begin playback after its buffered some of the video to disk or do I have to wait for the entire file to be written and then: MPMoviePlayerController* theMovie=[[MPMoviePlayerController alloc] initWithContentURL:theURL]; using the path to the local file. Thanks, Sam

• OpenGL ES, UIView and Status Bar mess

  - by sfider

  I have iPhone (iPhoneOS 3.x) OpenGL ES app that: can be in landscape/portrait orientation can be with/without status bar shown I do this by changing status bar orientation and hidden state, then updating OpenGL view frame so it won't overlap status bar and setting projection matrix appropriately. OpenGL view is in portrait orientation at all time. View controller's shouldAutorotateToInterfaceOrientation: method returns false always, so the status bar won't start autorotating when app is in landscape mode. The problem I have is that I want to use some other UIViews, like: UIWebView, MFMailComposeView, MPMediaPicker. I could show them as modals, but this this have some drawbacks: views will always show in portrait orientation, even if they support landscape orientation views will not autorotate, even if they support it What I do is I take OpenGL view of the window with removeFromSuperview, set transform to the other view so it will be in portrait/landscape orientation when it shows up and place the other view on the window with addSubview:. This works fine without the status bar, but with it there are some problems I cannot work out: MPMediaPicker is sized to fit under status bar, but it slides under it anyway MFMailComposeView does not show navigation bar until it autorotates on device orientation change Does anyone has an idea how can I get it to work?

• Are these AVAudioSettings right?

  - by Dyldo42

  self.recordSettings = [NSMutableDictionary dictionary]; [recordSettings setValue:[NSNumber numberWithInt:kAudioFormatAppleIMA4] forKey:AVFormatIDKey]; [recordSettings setValue:[NSNumber numberWithFloat:44100.0] forKey:AVSampleRateKey]; [recordSettings setValue:[NSNumber numberWithInt:1] forKey:AVNumberOfChannelsKey]; recordSettings is declared in my view's header file and initialised in its viewDidLoad method. For some reason, everything is working in the simulator, but on a device, the [recorder record] method is returning NO. The only theory I have is that something in the recordSettings isn't compatible with an actual device. Any ideas?

• Background image for list view still shows white behind text for cells.

  - by MonkeyTroy

  I wanted to put a background image partially visible behind a list view. I created a list view in my nib with an image view behind it and made the list view background 20% opacity. This allows the background image to show thru but my text in the cells show a white background behind and if I create the cells in cellForRowAtIndexPath the cells have a white background too. I am creating and setting the cell textLabel and the detailTextLabel in the cellForRowAtIndexPath event. Not sure how to get rid of that, or if there is a better way to do the background image.

• UiDatePicker displays but not UIPickerView

  If I drop a UIDatePicker onto a UIView in IB and run the app, the date picker displays. If I delete the date picker, drop a UIPickerView onto the same UIView and run the app, the UIPickerView doesn't display. What is the difference?

• Android - Clicking on notification in status bar binds the intent with the target activity

  - by araja

  I have created an activity which sends a number of notifications to status bar. Each notification contains an intent with a bundle. Here is the code: String ns = Context.NOTIFICATION_SERVICE; NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns); int icon = R.drawable.icon; long when = System.currentTimeMillis(); Notification notification = new Notification(icon, "Test Notification", when); Context context = getApplicationContext(); Bundle bundle = new Bundle(); bundle.putString("action", "view"); Intent notificationIntent = new Intent(this, MainActivity.class); notificationIntent.putExtras(bundle); PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, Intent.FLAG_ACTIVITY_NEW_TASK); notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent); mNotificationManager.notify(1, notification); When user clicks this notifications, I read the bundle string "action" and performs that action. Here is the code: Bundle bundle = this.getIntent().getExtras(); if(bundle != null) { String action = bundle.getString("action"); performAction(action) } Everything works as expected. But, when I minimize the app using "arrow" button on device and then press and hold home button and clicks on my app icon the application starts and performs the same last action which have been performed by clicking the last notification. I figured out that when we click the app icon the application starts with last intent triggered by the notification. Can anyone help in this?

• How to detect a Triangle gesture with kinect?

  - by Akhilesh Mishra

  I am trying to implement a gesture recognition system which interprets the geometric gestures user makes and draws it on screen, I have some idea of how circle can be recognized, however i have no clue how to get started with triangle recognition. the data I have is X and Y coordinates of all points the gesture passed through. I get this data by tracking right hand. I found something online called Hough Transform , which is used for detecting lines but i am not sure whether it will work for discrete collection of points, Any ideas folks?

• Easiest way to support multiple orientations? How do I load a custom NIB when the application is in

  - by Peter Hajas

  Hi there, I have an application in which I would like to support multiple orientations. I have two .xib files that I want to use, myViewController.xib and myViewControllerLandscape.xib. myViewController.xib exists in project/Resources and myViewControllerLandscape.xib exists in the root project directory. What I want to do is use a separate NIB (myViewControllerLandscape.xib) for my rotations. I try detecting rotation in viewDidLoad like this: if((self.interfaceOrientation == UIInterfaceOrientationLandscapeLeft) || (self.interfaceOrientation == UIInterfaceOrientationLandscapeRight)) { NSLog(@"Landscape detected!"); [self initWithNibName:@"myViewControllerLandscape" bundle:nil]; } But I can see in gdb that this isn't executed when the app is started with the device in landscape. The NSLog message doesn't fire. Why is this? What have I done wrong? Also, if I explicitly put the initWithNibName function call in the viewDidLoad method, that nib is not loaded, and it continues with the myViewController.xib file. What's wrong with my call? Should I specify a bundle? Thanks!
