You need to add:

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

so your full intent-filter section looks like this:

        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
            <category android:name="android.intent.category.HOME" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>

Not this still won't FORCE the app to run at boot. This will just add it to the list of launchers. It will only launch at boot if the user chooses it as their default launcher.

If you want to run an activity at launch, you can register a broadcast receiver to handle the ON_BOOT_COMPLETED action, but think very carefully before doing so; is this what all users of your app would want?
