Connected put not working after wifi changed

[joe80-80]

Hi,
I have a project in my university that uses openvpn, and I facing problem in some cases, when wifi is changed or (wifi turned off for a while), the problem is when is return back the app automatically connect again and it seems to be connected, but not working until manually reconnect again

is there any configuration that force the vpn to be reconnect when its paused (or no network),
if not, I am trying to modify the code ( I built it successfully using android studio ) and the question is where to modify and what I have to add ?

Information:
Android Version: 13 (I tested the same case on android 10 and no problem)
Device: samsung galaxy s20
Version of the app (0.7.53)

thanks

So at what point/time in the log did you switch wifi? I see a succesfull reconnect in the log is that the change?

[schwabe]

That sounds really like it can be only reproduced on the Samsung phone with the Android 13 which means that this hard for me to reproduce as my only Samsung device is an old S6.

[joe80-80]

I agree with you,
Now in my case which must includes android 13, I have to solve it, so I asked a help in modifying the code (to disconnect and connect again when no network), would you please help me

by the way, solving it with this discussion will presented in my report in university, and will be useful for my degree :)

[schwabe]

To be honest since we already opening a new VPN with OPENTUN again, so we are already basically going through the whole disconnect/connect cycle. So short of actually figuring out what is happening, you probably really have to stop and start the OpeNVPN daemon again. And that is something that will need more effort. You can also try what happens if you use the OpenVPN 3.x core and see if that makes a difference.

[joe80-80]

Yes, that's good approach, but due of the deadline and the environment that I already prepared for my project, I have to continue with the path of modifying the source code, all what I need is a help or some hints if available, about that, I made some research and found that I may modifying in this file main/src/main/java/de/blinkt/openvpn/core/DeviceStateReceiver.java in this function networkStateChange like this:

`public void networkStateChange(Context context) {
ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
// Check if network is available
if (activeNetwork != null && activeNetwork.isConnected()) {
reconnectVPN();
} else {
VpnStatus.updateStateString("NONETWORK", "", R.string.state_nonetwork, ConnectionStatus.LEVEL_NONETWORK);
}
}

private void reconnectVPN() {
final Handler handler = new Handler();
final Runnable reconnectRunnable = new Runnable() {
@OverRide
public void run() {
if (isNetworkAvailable()) {
startOpenVPN();
} else {
handler.postDelayed(this, 5000); // Retry every 5 seconds
}
}
};
handler.post(reconnectRunnable);
}

private boolean isNetworkAvailable() {
ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
return activeNetwork != null && activeNetwork.isConnected();
}
`
Is that logic is rights?

• How to use startOpenVPN(); function ?
• Is I have to specify a profile?
• What to import?

[schwabe]

Directly calling startOpenVPN will not work. You probably want to generate yourself an intent from the profile to start yourself. See LaunchVPN.java for all the extra stuff that is done around startVPN.
