Black screen shown after camera intent

Question

I modified the StopWatch demo application for Glass to start working with the camera on demand when the side is being listened. The intent code is copied from the Google documentation.

When I click, the onPause callback for my application starts, but the screen goes black, not the camera’s preview. Pressing it again does nothing - onResume is not called. However, scrolling brings me back to StopWatch activity.

Is this like a bug with a camera aimed at Glass, or is it something at my end?

Stopwatch operation

private static final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 100; // 1337 also doesn't work public boolean onKeyDown(int keyCode, KeyEvent event) { switch (keyCode) { case KeyEvent.KEYCODE_DPAD_CENTER: case KeyEvent.KEYCODE_ENTER: Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE); intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); // file:///mnt/sdcard/Pictures/MyCameraApp/IMG_20130812_105617.jpg // start the image capture Intent startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE); return true; default: return super.onKeyDown(keyCode, event); } }

It looks like your code is correct. Please write a bug report in our problem tracking .

Alternatively, you can try using the Camera class to take photos.
