Android Camera : data intent returns null

Question

I have an android application which contains multiple activities.

In one of them I'm using a button which will call the device camera :

public void onClick(View view) {
    Intent photoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(photoIntent, IMAGE_CAPTURE);
}

In the same activity I call the OnActivityResult method for the image result :

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == IMAGE_CAPTURE) {
        if (resultCode == RESULT_OK) {
            Bitmap image = (Bitmap) data.getExtras().get("data");
            ImageView imageview = (ImageView) findViewById(R.id.pic);
            imageview.setImageBitmap(image);
        } else if (resultCode == RESULT_CANCELED) {
            Toast.makeText(this, "CANCELED ", Toast.LENGTH_LONG).show();
        }
    }
}

The problem is that the intent data is null and the OnActivityResult method turns directly to the (resultCode == RESULT_CANCELED) and the application returns to the previous avtivity.

How can I fix this issue and after calling the camera, the application returns to the current activity which contains an ImageView which will contains the picture taken?

Thanks

The default Android camera application returns a non-null intent only when passing back a thumbnail in the returned Intent. If you pass EXTRA_OUTPUT with a URI to write to, it will return a null intent and the picture is in the URI that you passed in.

You can verify this by looking at the camera app's source code on GitHub:

• https://github.com/android/platform_packages_apps_camera/blob/gingerbread-release/src/com/android/camera/Camera.java#L1186

  Bundle newExtras = new Bundle();
  if (mCropValue.equals("circle")) {
      newExtras.putString("circleCrop", "true");
  }
  if (mSaveUri != null) {
      newExtras.putParcelable(MediaStore.EXTRA_OUTPUT, mSaveUri);
  } else {
      newExtras.putBoolean("return-data", true);
  }
  

I would guess that you're either passing in EXTRA_OUTPUT somehow, or the camera app on your phone works differently.
