title: Video recording without preview
body: <p>I am able to record a video on Android, but can I do so without previewing the video on my screen?</p>
  <p>Here is the working code for the <code>surfaceView</code>:</p>
  <pre><code>surfaceView = (SurfaceView) findViewById(R.id.surface_camera);
  surfaceHolder = surfaceView.getHolder();
  surfaceHolder.addCallback(this);
  surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
  </code></pre>
  <p>Can I manually input the size of <code>surfaceHolder</code> instead of doing</p>
  <pre><code>surfaceHolder = surfaceView.getHolder();
  </code></pre>
  <p>Thank you</p>
