Android Question [SOLVED] Monitor phone to network connection ?

[lemonisdead]

Hello,

I am facing a problem I can not solve : I am in need of detecting if the phone is connected to its network and warn if the connection is lost.

The only way I had found was to use a service and use PhoneEvents then ConnectivityChanged event. But this seems only to catch the lost of connection when the data are on only.

Using a broadcast receiver on android.net.conn.CONNECTIVITY_CHANGE won't return the "reason" any time.

Please, do you know a way to detect if the phone is connected to its network without data ?

Many thanks

You can also check the device ip address with ServerSocket. It should be different than 127.0.0.1.

Eventually the best way to make sure that there is a live connection is to send a real request and check the result. You can use a timer to send a small http request every minute.

I think she cares about connectivity to the radio network.

As Erel said, checking a real site is the only way to detect that you are not stuck in a captured portal (those login pages to wifi networks you get to regardless of which URL you specify).

Hello,

Excuse me, I had some technical troubles I couldn't reply previously. Thanks for your ideas. I will try.

Yes, you are right. Thanks for the word "radio network". I will be able to make further googling about.

Thanks to your help, I have got my solution : PhoneStateListener
- android : http://developer.android.com/reference/android/telephony/PhoneStateListener.html
- b4a : https://www.b4x.com/android/forum/threads/phonestatelistener.12377

The idea is to receive the onServiceStateChanged and especially STATE_OUT_OF_SERVICE
Leaving this here for others
