Launching external application from my app

Question

I would like to launch an app the user selects from within my application. However, I\'m not sure how I\'d go about doing this. I\'ve tried this:

Intent inte         


        

Answer 1

I use this code for that purpose:

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setClassName("com.android.settings", "com.android.settings.Settings"); 
startActivity(intent);

This will launch the Settings app, you can use these also:

intent.setClassName("com.android.music", "com.android.music.MediaPlaybackActivityStarter");
intent.setClassName("com.android.contacts", "com.android.contacts.DialtactsContactsEntryActivity");
intent.setClassName("com.android.contacts", "com.android.contacts.DialtactsActivity");

The first starts the default music app, the second the contacts, and the third the dialer. Hope this helps.
