title: OpencvAndroidSDK : Switching between Front camera and Back camera at run-time?
body: <p>I have this NativeCameraView :</p>
  
  <pre><code>&lt;org.opencv.android.NativeCameraView
              android:id="@+id/tutorial1_activity_native_surface_view"
              android:layout_width="350px"
              android:layout_height="350px"
              android:layout_marginLeft="5dp"
              android:layout_marginTop="5dp"
              opencv:camera_id="front" /&gt;
  </code></pre>
  
  <p>By changing <code>opencv:camera_id="front"</code> to <code>opencv:camera_id="back"</code>, I can change from front camera to back camera at design time( Can I call it compile time ?! )<br>
  But now I need to switch between them at run-time ? Is it possible?</p>
