Android - share images with Instagram, Google+ etc

Question

I have this code which I found on another SO

  Bitmap icon = myBitmap;
  Intent share = new Intent(Intent.ACTION_SEND);
  share.setType("image/jpeg");

  ContentValues values = new ContentValues();
  values.put(Images.Media.TITLE, "title");
  values.put(Images.Media.MIME_TYPE, "image/jpeg");

  ContentResolver contentResolver = getContentResolver();
  Uri uri = contentResolver.insert(Media.EXTERNAL_CONTENT_URI, values);

  OutputStream outstream = null;
  try {
      outstream = getContentResolver().openOutputStream(uri);
      icon.compress(Bitmap.CompressFormat.JPEG, 100, outstream);
      outstream.close();
  } catch (Exception e) {
      System.err.println(e.toString());
  }

  share.putExtra(Intent.EXTRA_STREAM, uri);
  startActivity(Intent.createChooser(share, "Share Image"));

However, it creates an exception in the call to insert - maybe because I do not have a SD card in my phone. I can not say for sure since no log seems to be generated. And when I step through code, it seems I am stepping through comments, so it would appear something is wrong in my Eclipse installation. (Normally logs are generated and stepping works fine.)

Ideally, I would like to have code that is not dependent on external storage (I believe Instagram and Google+ image sharing requires this from what I can read), but which would fallback to local app storage if SD card not available. I know that wouldy limit share options, but sthat is till better than nothing.

Later-on, I need to merge this with camera functionality which is why the input currently is myBitmap.

You need to follow this guide provided by Google. As this feature is included as standard by Android 4.0 it should not be difficult to implement.
