<p>I try to invoke MMS's Attach Image ACtivity, this is my code:</p>

<pre><code>          Intent intent2 = new Intent("com.android.mms.action.ATTACH_IMAGE");

          intent2.setType("image/*");
          intent2.putExtra(Intent.EXTRA_STREAM, mUri);

          try {
              startActivity(intent);

          } catch (ActivityNotFoundException e) {

             e.printStackTrace(System.err);
          }
</code></pre>
