Have you seen this:
startActivity() from BroadcastReceiver

It doesn’t look like you are using Context.registerReceiver() so you would have to statically add your receiver to the manifest, if you haven’t already:

make sure you have the following in your manifest

<receiver android:name=".AlarmNotificationReceiver">
    <intent-filter>
            <action android:name="android.intent.action.PHONE_STATE" />
    </intent-filter>
</receiver>

Above, PHONE_STATE is just an example of an intent that may be used in conjuntion with the BroadcastReceiver
