Answer 1

In Android 3.0 and higher, an bootup reciever will not run until the activity has been launched at least once by hand. So most likely you aren't ever running.

You aren't appearing in the grid because you have no launcher activity. Add this to the activity tag in your manifest

        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>

Then run the app once. After that it ought to work.
