title: How to change maxFrameSize of JavaCameraView at runtime
body: <p>I have an Android App with OpenCV which should be able to change the frame size of the JavaCameraView at runtime.
  Because a lot processing on the delivered frame I set the resolution of the frame at App start on 320 x 280. I do this like that:</p>
  
  <pre><code>protected void onCreate(Bundle savedInstanceState) {
      cameraView = (JavaCameraView) findViewById(R.id.cam_view);
      cameraView.setMaxFrameSize(320, 280);
      cameraView.setCvCameraViewListener(this);
  </code></pre>
  
  <p>I created a RadioButton Group in which I can choose the resolution for the frame. Here is my code;</p>
  
  <pre><code>resolutionChange = new Dialog(this);
      resolutionChange.requestWindowFeature(Window.FEATURE_NO_TITLE);
      resolutionChange.setContentView(com.finarx.opencv.camera.R.layout.resdialog);
  
      RadioGroup resChange = (RadioGroup) resolutionChange.findViewById(com.finarx.opencv.camera.R.id.resChange);
      resChange.setOnCheckedChangeListener(new OnCheckedChangeListener() {
  
          @Override
          public void onCheckedChanged(RadioGroup group,
                  int checkedId) {
              if (checkedId == com.finarx.opencv.camera.R.id.lowest) {
                  cameraView.setMaxFrameSize(320, 280);
                  resolutionChange.dismiss();
              } else if (checkedId == com.finarx.opencv.camera.R.id.low) {
                  cameraView.setMaxFrameSize(480, 320);
                  resolutionChange.dismiss();
              } else if (checkedId == com.finarx.opencv.camera.R.id.vga) {
                  cameraView.setMaxFrameSize(640, 480);
                  resolutionChange.dismiss();
              } else if (checkedId == com.finarx.opencv.camera.R.id.higher) {
                  cameraView.setMaxFrameSize(800, 600);
                  resolutionChange.dismiss();
              } else if (checkedId == com.finarx.opencv.camera.R.id.highest) {
                  cameraView.setMaxFrameSize(1280, 720);
                  resolutionChange.dismiss();
              }
          }
      });
  </code></pre>
  
  <p>In fact, nothing happens to the resolution of the frame when I choose another resolution. Of course I also tried to reinitiate the cameraView object. Is there anything I miss?</p>
