To get the applications that can successfully open a given intent you'll use the PackageManager. Simply construct the intent as above and then use this code to get the applications that can handle the intent.

Intent myIntent = new Intent();
myIntent.setAction(Intent.ACTION_VIEW);
myIntent.addCategory("android.intent.category.LAUNCHER");
myIntent.setType("mp3");    

PackageManager manager = getPackageManager();
List info = manager.queryIntentActivities(
    myIntent, PackageManager.MATCH_DEFAULT_ONLY);

This will give you all the information on the programs that can handle the intent, including icon, and packagename. You can then create a dialog box with these options and save the option the user chooses.
