Samples not working on Samsung Galaxy SL

edit

So, here is what I did, not a real solution, but it may point someone where the real problem is. As I commented, it seems obvious that you can't draw on the same surface used for the camera preview...

I modified SampleViewBase.java in the Tutorial 0 this way to have it working:

public SampleViewBase(Context context) {
[...]
mHolder.setType( SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS );

}

public void setPreview() throws IOException { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) mCamera.setPreviewTexture( new SurfaceTexture(10) ); else mCamera.setPreviewDisplay(mHolder); }

public void surfaceCreated(SurfaceHolder holder) { Log.i(TAG, "surfaceCreated"); mHolder = holder; (new Thread(this)).start(); }

public void run() { [...] while (mThreadRun) { [...]

    if (bmp != null) {
        /*
        Canvas canvas = mHolder.lockCanvas();
        if (canvas != null) {
            canvas.drawBitmap(bmp, (canvas.getWidth() - getFrameWidth()) / 2, (canvas.getHeight() - getFrameHeight()) / 2, null);
            mHolder.unlockCanvasAndPost(canvas);
        }
        */
    }
}

}
