title: View image in ACTION_VIEW intent?
body: <p>I'd like to show a png or jpg I downloaded from the next in an image viewer intent, but can't get it to work.</p>
  
  <pre><code>Bitmap bmp = getImageBitmap(jpg);
  String path = getFilesDir().getAbsolutePath() + "/test.png"; 
  File file = new File(path); 
  FileOutputStream fos = new FileOutputStream(file);
  bmp.compress( CompressFormat.PNG, 100, fos ); 
  fos.close(); 
  
  Intent intent = new Intent();
  intent.setAction(android.content.Intent.ACTION_VIEW);
  intent.setDataAndType(Uri.fromFile(new File(path)), "image/png");
  startActivity(intent);
  </code></pre>
  
  <p>I know the bitmap is downloaded ok (use the same routine for supplying it my ImageView instances elsewhere in my app) - I think it wrote to file ok, I can see it on disk and the file size is correct. The intent is launched but an exception is thrown:</p>
  
  <blockquote>
    <p>ERROR/ImageManager(1345): got exception decoding bitmap java.lang.NullPointerException</p>
  </blockquote>
  
  <p>then the new activity just sits there, blank. How does this work?</p>
