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, and it opens the Android Messaging app just like as if I was to press the Messaging icon on the main screen.

I did something similar to this with the Contacts activity, but only the contact list comes up, no extra functionality like Adding/Modifying/Deleting, etc.

Any ideas?

edit: I found this way to open the "Compose New Message" Activity, I just need to back it up a step. Does anyone know the correct MIME type instead of this one?

Intent sendIntent = new Intent(Intent.ACTION_VIEW); 
sendIntent.setType("vnd.android-dir/mms-sms"); 
m_activity.startActivity(sendIntent); 

Answer 1

This starts the messaging app from another app:

Intent intent = new Intent("android.intent.action.MAIN");
intent.setComponent(new ComponentName("com.android.mms","com.android.mms.ui.ConversationList"));
startActivity(intent);

Just put it inside a button listener or whatever user input you want to open it from.

Enjoy :-)
