title: Can I make a texture from specific fragment?
body: <p>I want to make a texture from fragment(with FragmentActivity)'s content.
  I use OpenGL ES2.0.</p>
  
  <p>I try to render fragment to frame buffer by binding frame buffer in onCreate().
  I think that if it is possible, the fragment won't be displayed. However, it doesn't work. It was displayed.</p>
  
  <p>I have no idea to do this, now.
  How can I do this?</p>
