title: Share Bitmap() on android to twitter, facebook, mail
body: <p>maybe an easy question: I want to share a bitmap I received over the net to twitter/facebook/etc with the default share "intent".</p>
  
  <p>The code I found</p>
  
  <pre><code>        Intent sendIntent = new Intent(Intent.ACTION_SEND);
          sendIntent.setType("image/jpeg");
          sendIntent.putExtra(Intent.EXTRA_STREAM, "IDONTKNOW");
          sendIntent.putExtra(Intent.EXTRA_TEXT,
                  "See my captured picture - wow :)");
          startActivity(Intent.createChooser(sendIntent, "share"));
  </code></pre>
  
  <p>needs to be filled at the point "IDONTKNOW" with the bitmap. (this.bitmap)</p>
  
  <p>I found no way to handle this without saving the bitmap to internal sd..</p>
  
  <p>regards</p>
