I'm using an ODROID-U2 that I upgraded to Android version 4.2.1.8., openCV 2.4.7.1, USB web-camera After the running examples(camerapreview) the frames don't move.But if we move the mouse,the frames begin exchange(only when the mouse is moved).And when the mouse stop moving,the exchange of frames stop too.

I solved the same problem by changing following lines in JavaCameraView.java (in OpenCV4Android Library):

1) Size frameSize = calculateCameraFrameSize(sizes, new JavaCameraSizeAccessor(), width, height);

to

Size frameSize = new Size(width,height);

2) Log.d(TAG, "Set preview size to " + Integer.valueOf((int)frameSize.width) + "x" + Integer.valueOf((int)frameSize.height));

to

Log.d(TAG, "Set preview size to " + Integer.valueOf(640) + "x" + Integer.valueOf(480));

3) params.setPreviewSize((int)frameSize.width, (int)frameSize.height);

to

params.setPreviewSize((int)640, (int)480);
