Android camera locked after force close

Question

I have an application where I use devices camera.

Now I only release camera in normal flow.

@Override
public void surfaceDestroyed(SurfaceHolder surf         


        

Answer 1

As @CommonsWare suggested, if you want to make sure, that your application releases Camera before crashing you should use Thread.setDefaultUncaughtExceptionHandler().

Or if you're using Bugsense:

private class MyCameraActivity extends Activity implements SurfaceHolder.Callback, ExceptionCallback {

    @Override
    protected void onCreate(Bundle sSavedInstanceState) {
        super.onCreate(sSavedInstanceState);

        BugSenseHandler.setExceptionCallback(this);
    }

    @Override
    public void surfaceCreated(SurfaceHolder holder) {
        this.camera = open();

        try {
            camera.setPreviewDisplay(holder);
        } catch (IOException e) {
            Log.e(TAG, e.getMessage(), e);
        }

        // other camera stuff
    }

    @Override
    public void surfaceDestroyed(SurfaceHolder surfaceHolder) {
        releaseCamera();
    }

    @Override
    public void lastBreath() {
        releaseCamera();
    }

    private void releaseCamera() {
        if (camera != null) {
            camera.stopPreview();
            camera.release();
        }
    }
}
