Check when mobile data is connected using BroadcastReceiver | Android

Question

I would like to know how can I check when mobile data is connected using BroadcastReceiver.

Here's what I have so far:

    private BroadcastReceiver MobileDataStateChangedReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        int state = intent.getIntExtra(TelephonyManager.EXTRA_STATE,
                TelephonyManager.DATA_DISCONNECTED);

        if (state == TelephonyManager.DATA_CONNECTED) {
            mobileStatus.setText("Connected");
        } else if (state == TelephonyManager.DATA_DISCONNECTED) {
            mobileStatus.setText("Disconnected");
        }
    }
};

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.status_page);

    mobileStatus = (TextView) this.findViewById(R.id.textView4);

    registerReceiver(MobileDataStateChangedReceiver, new IntentFilter(
            TelephonyManager.ACTION_PHONE_STATE_CHANGED));
}

What am I doing wrong in here?

I used the same concept on Wi-Fi checking and it worked great? I am using the permissions of:

<uses-permission android:name="android.permission.INTERNET"/>

The TelephonyManager.ACTION_PHONE_STATE_CHANGED does not seem to work because as I could read in TelephonyManager class description it only fires with calls, but not with networks or mobile data. Instead of this, I suggest you try setting a listener. It would be something like this:

1) Get the service with TelephonyManager tm = (TelephonyManager)Context.getSystemService(Context.TELEPHONY_SERVICE)

2) Set a listener with tm.listen(myCustomPhoneStateListener, PhoneStateListener.LISTEN_DATA_CONNECTION_STATE);

3) Once you have the listener you will be able to send custom intents to your BroadcastReceiver, if you still want to do that.

Thank you very much.. it worked and after what u said I searched for PhoneStateListener.LISTEN_DATA_CONNECTION_STATE and also got this: http://stackoverflow.com/questions/6179906/how-can-i-receive-a-notification-when-the-device-loses-network-connectivity – dinbrca Jul 05 '13 at 22:44
You are welcome. I also was looking for something similar for my Android application in order to prevent long downloads :) – José Molina Jul 06 '13 at 00:23
