title: Open Picture stored in res/drawable with buildin Android Image Viewer
body: <p>is it possible to open an picture, which is stored in the res/drawable folder with the Android build in Image Viewer? I don't get it work. I tried the follwoing way</p>
  
  <pre><code>Button ButtonPhase2 = (Button) findViewById(R.id.button1);
      ButtonPhase2.setOnClickListener(new View.OnClickListener() {
          public void onClick(View view) {
  
              Intent myIntent = new Intent(android.content.Intent.ACTION_VIEW);
              myIntent.setData(Uri.parse("android.resource://de.test.app/" + R.drawable.testbild));
              myIntent.setType("image/png");
              startActivityForResult(myIntent, 1);
  
          }
  
      });
  </code></pre>
  
  <p>But I get the Error:</p>
  
  <pre><code>Unable to start Activity ComponentInfo{com.android.gallery/com.android.camera.ViewImage}: java.lang.nullPointerException
  </code></pre>
  
  <p>I think it is the wrong path?</p>
