title: How to use setImageUri() on Android
body: <p>Can you help me please? I've tried :</p>
  
  <pre><code>ImageButton imgbt=(ImageButton)findViewById(R.id.imgbutton);
  Uri imgUri=Uri.parse("/data/data/MYFOLDER/myimage.png");
  imgbt.setImageUri(imgUri);
  </code></pre>
  
  <p>but I didn't see anything, simply a void button.</p>
