MIME types and ACTION_SEND intent chooser

I'm using very standard code to send images from my app. A user emailed me that their default messaging app doesn't show up in the chooser, and oddly enough the same happens on my phone. I was playing around with the MIME type of the intent. "text/plain" shows a set of options including my Messages app, and "*/*" shows a ton. Would I be lazy to set the MIME type to "*/*" so that I don't get filtered by apps that should be an option for the user to send images? Or is that pretty much the way to go?

        Intent intent = new Intent(Intent.ACTION_SEND);
        intent.setType("image/jpeg");
        Uri uri = Uri.fromFile(file);
        intent.putE开发者_JAVA百科xtra(Intent.EXTRA_STREAM, uri);
        activity.startActivity(Intent.createChooser(intent, "Custom Heading..."));

One side effect of this that I don't like is that a few apps (Facebook, Handcent) have multiple intents registered to send various MIME types, so they show up in the list more than once when the MIME type is "*/*".

The built in messaging should handle your mime type, so it may be a platform specific issue:

       <intent-filter>
           <action android:name="android.intent.action.SEND" />
           <category android:name="android.intent.category.DEFAULT" />
           <data android:mimeType="image/*" />
       </intent-filter>
