java.lang.UnsupportedOperationException at java.nio.ByteBuffer.arrayOffset

[frank0123]

private final IFrameCallback callback = new IFrameCallback() {
    @override
    public void onFrame(final ByteBuffer frame) {
        new Thread(new Runnable() {
            byte[] bytes = new byte[frame.remaining()];
            frame.get(bytes);

            if(bytes.length > 0) {
                int offset = frame.arrayOffset();
                Bitmap bitmap = BitmapFactory.decodeByteArray(bytes, offset, bytes.length - offset);
                ......
            }
        }).start();
    }
}

use createBitmap instead of decodeByteArray, I got this exception:

java.lang.RuntimeException: Buffer not large enough for pixels at android.graphics.Bitmap.copyPixelsFromBuffer

private final IFrameCallback callback = new IFrameCallback() {
    @override
    public void onFrame(final ByteBuffer frame) {
        new Thread(new Runnable() {
            Bitmap bitmap = Bitmap.createBitmap(UVCCamera.DEFAULT_PREVIEW_WIDTH, UVCCamera.DEFAULT_PREVIEW_HEIGHT, Bitmap.Config.ARGB_8888);
            bitmap.copyPixelsFromBuffer(frame);
            ......
        }).start();
    }
}

PS: First, I applied this uvcCamera.setFrameCallback(frameCallback, UVCCamera.PIXEL_FORMAT_NV21);

And, when I check this: if(frame.hasArray()) { }

it returns false!
