root - Create VPN profile on Android

Question

Is it possible to programmatically create VPN profile on Android (assuming that I have a rooted device)?

If is possible, how?

Thanks.

Answer 1

You should look at the com.android.settings.vpn2 package. There it uses the @hidden KeyStore methods to manipulate VPNs:

• KeyStore.getInstance().saw(Credentials.VPN) returns an array of String VPN IDs

• VpnProfile.decode(KeyStore.getInstance().get(Credentials.VPN + vpn_id)) gets the VPN configuration data for the given VPN ID and decodes it as a VpnProfile object.

• VpnProfile.put(Credentials.VPN + vpn_id, someVpnProfileInstance.encode()) will create/update a VPN connection with the given ID using the settings in the VpnProfile instance.

However, you will need to execute this as the system process -- otherwise, the KeyStore instance you get will not be connected to the one that the OS uses.

If there is a way to do this without a rooted device, I'd be interested in knowing how...
