<action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
<action android:name="android.intent.action.BOOT_COMPLETED" />
I don't understand if it's needed to be notified. If it were true any app could call my receiver with those actions? So If I make it false the system can send the actions to my receiver?
Actually, others apps cannot "call your receiver". Other apps can just send broadcast
Intents. The System will then call all registered receivers.
In general you shouldn't worry about this. Most of these broadcast
Intents are protected so that only system apps can broadcast them anyway. An attempt by another app to broadcast
BOOT_COMPLETED, for example, would just be ignored. What would happen if your
BroadcastReceiver gets triggered by a rogue app because it broadcast
CONNECTIVITY_CHANGE? Probably nothing, because your app should check the real connectivity state in
onReceive() anyway, and if there isn't any change you can just ignore it.
Also, you don't need to specify
android:enabled="true" because this is the default state. You also don't need to specify
android:exported="true" because you have an
<intent-filter> attached to your
<receiver> which automatically sets
