Get Network on android.intent.action.BOOT_COMPLETED

Question

I've an app that has a receiver of android.intent.action.BOOT_COMPLETED and start a private VPN. But when I receive a android.intent.action.BOOT_COMPLETED the network isn't ready yet. What can I do to start a android.intent.action.BOOT_COMPLETEDand wait to have a network status? for example I can have a android.intent.action.BOOT_COMPLETED but the phone has no internet connection, or I can have a android.intent.action.BOOT_COMPLETED and 5 seconds later a internet Access.

Answer 1

You could register a broadcast receiver listening on the android.net.conn.CONNECTIVITY_CHANGE action.

then check if you are connected like this:

public boolean isOnline(Context context) {

ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo netInfo = cm.getActiveNetworkInfo();
//should check null because in air plan mode it will be null
return (netInfo != null && netInfo.isConnected());

}

Answer 2

You can always listen to multiple items on one receiver:

<receiver android:name=".ReceiverName" >
    <intent-filter >
        <action android:name="android.net.wifi.STATE_CHANGE" />
        <action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
        <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</receiver>

So after boot you just wait for connectivity change and do your stuff.
