Accessing Android Inbox/Messaging from Activity?

Question

Is it possible to open up the default Android Messaging activity from inside an activity you write yourself? Like for example: I press a \"Mail\" button inside my program,

Answer 1

If you want to open the messaging app to view messages and not for sending a message, this should do the job:

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
intent.setPackage("com.google.android.apps.messaging");
startActivity(intent);
