I am using the class JavaCameraVIew and CvCameraViewListener2 for a Android application. With these classe, i am trying to get each frame and analyze it but my application works a few minutes and crashes with these errors:

W/InputMethodManagerService(  765): Session failed to close due to remote exception

I could find the error but i don't know how i should fix it .... The error is if i want to copy a frame in order to apply another operations...

My main Activity.java is:

public class TrackerActivity extends Activity implements CvCameraViewListener2 {
    private JavaCamResView openCVCameraView;
    public TrackerActivity() {
        Log.i(TAG, "Instantiated new " + this.getClass());      
        appContext = (new AppContextFactory()).create();

    }
        ...
        ..
        .

    @Override
    public Mat onCameraFrame(CvCameraViewFrame frame) {
        Mat outputFrame = outputFrame = frame.rgba().clone();   <- the ERROR is here....    
        return outputFrame;
    }

Is it normal that i can not copy input frames..? In my opinion, it shouldn't be a problem.... Furthermore, Does somebody know how i could do to fix this error?

I didn't add all the stacktrace and classes because it can be tedious, but i uploaded in a pastebin web:
