I have a class (CameraView) that I use to take pictures within my app.
When running on a LG Nexus 4 (Android 4.2.1) there is no callback to onPictureTaken. Below is a basic example of how I am trying to achive this (i've obmitted all the initialisation stuff but it does happen). This code works and takes pictures on Galaxy Nexus (Android 4.2.1) and Galaxy S3 (Android 4.0.3) but not on a Nexus 4. I've tested for the callback onShutter() and all the onPictureTaken() ones too, raw, postview and jpeg but None of them are called when running on a Nexus 4.
EDIT:
In my first activity I have a button which starts the camera.
mImage = (Button) findViewById(R.id.takeimg);
mImage.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
startActivityForResult(new Intent(MyClass.this, CameraView.class), ACTION_ACTIVITY_PHOTO);
}
});
In my camera activity I have the following:
public class CameraView extends Activity implements PictureCallback{
private Camera mCamera;
private ImageButton mShutterBtn;
public void onCreate(Bundle savedInstanceState) {
mCamera = Camera.open();
mShutterBtn = (ImageButton) findViewById(R.id.shutter);
mShutterBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
mShutterBtn.setImageResource(R.drawable.shutter_pressed);
close_shutter();
}
});
}
protected void onResume() {
mCamera.startPreview();
}
private void close_shutter(){
mCamera.takePicture(null, null, this);
}
public void onPictureTaken(byte[] data, Camera camera) {
//save image...
setResult(RESULT_OK);
finish()
}
}
Below is the verbose LogCat log for what happens from the time the Activity starts, through attempting to take the image and then finishing the activity. I can't see anything in it that points me to an issue with my code. Any help will be apreciated.

So, based on the info in this zxing issue i've been playing around with this today, my current code (that doesn't work) is:
List<Size> supportedPreviewSizes = mCamera.getParameters().getSupportedPreviewSizes();
parameters.setPreviewSize(supportedPreviewSizes.get(2).width, supportedPreviewSizes.get(2).height);
If i change this to:
List<Size> supportedPreviewSizes = mCamera.getParameters().getSupportedPreviewSizes();
parameters.setPreviewSize(supportedPreviewSizes.get(0).width, supportedPreviewSizes.get(0).height);
Then it gets the callbacks. Now I know (from being in debug) that getSupportedPreviewSizes returns me a list with 12 items in it so there is no index out of bounds exception going on. I don't know why this works but it does (in my case). Anyone who can provide an explination? Or a comment on how others choose which size to use, is there some logical way to determine which size is "the best"? Unfortunately "the best" is subjective depending on what you want to use the image for?
