Prevent user to change WIFI/SSID

[yckhor]

Hi,
We are giving away Android devices (non-phone) to our users to make VOIP calls using CSipSimple app over WIFI SSID:WIFIVOIP but frequently, we found that users fiddling with the settings and connected to another SSID thus making the VOIP calls not possible. Can anyone advice what should we do?

1. How can we prevent the change? listen to the broadcast of intent and block it? how to do that?

2. Develop an app/service to reconnect back to SSID:WIFIVOIP when an intent/change is being detected

3. Prevent user to access Android device "Settings" and prompt for a password

Looking forward to hear from you

Hi,

you might try to create a service (with "Start at boot" option) using this library here:

http://www.b4x.com/forum/additional...tes/17150-wifi-manager-library.html#post98044

This library allows you to detect the current wifi state and sets wifi on or off.

So the service should check if wifi is on. If not, the service should set wifi on.

Best regards,

Carsten

Dear Carsten,
Thanks for the prompt reply. We developed an app and did just that. It seems to work at the moment. Will share findings when further tests being conducted tomorrow.

Also, if the user exits the CSipSimple app, how can we intercept the intents to quit the app so that we can start another instance of the app to resume communication?

Thanks in advanced.

Hi,

Could your app check if communication is possible (which would mean that CSipSimple is running)?

If so, you could use this to launch the CSipSimple app again, if communication fails:

dim pm as PackageManager
dim in as Intent
in = pm.GetApplicationIntent("CSIPSimple.package.name")
StartActivity(in)

Replace "CSIPSimple.package.name" with the correct package name of that app...

Best regards,

Carsten
