How to configure a static IP address netmask gateway programmatically on Android 3 x or 4 x

Question

It's true that I can retrieve the values I set using android.provider.Settings.System.getString(). It demonstrates that the setting is saved somewhere but is just ignored by the system.

Instead of using android.provider.Settings, the system utilises another setting.

As the setting is set according to the SSID of the access point, system on Android 3.x and 4.x. Can I change a single SSID's setting in the same way as Android 2.3 does?

Answer 1

Your application will be rejected if you try to use the solution for Android 5.x on 6.x. You'll probably need to root your device and give the application device ownership in order to accomplish this.

I've looked into the issue a bit, and what I've discovered is that if the application is set to be the device owner, the code that used to function for Android 5.x might still work.

Using adb shell, issue the following command:

Device Owner Receiver: dpm set-device-owner com.example.android.deviceowner

will provide the application device ownership, and a static IP address can be specified.
