I spent a lot of time debugging different problems that were reproducible only on a specific devices.
For instance I left my attempts to take a picture from a camera using an Intent. Because only a limited set of the devices behave as expected.
Another example is when I use a byte array from the onPictureTakenCallback:
public void onPictureTaken(byte[] data, Camera camera) {
byte[] tempData = new byte[data.length];
System.arraycopy(data, 0, dataTemp, 0, data.length);
///...
}
So if I don't make a copy, but use original "data" array some time later then I fall into troubles because some devices clean this array up after a time. But other devices don't do such cleaning so it works perfectly without doing a copy.
One more example: Some devices return null when:
Camera.Parameters params = camera.getParameters();
List<Camera.Size> sizes = params.getSupportedPreviewSizes();
// sizes is null
But most of devices (I think) return a list of supported sizes.
So I wonder if is there any kind of knowledge base / FAQ assembled of such problems? If not, let's post here issues with which we faced?
