How to change WifiConfigration in Oreo device

Question

I used https://github.com/aegis1980/WifiHotSpot code to start and stop Hotspot from my application. But it will only start and stop the hotspot that cannot change the Wifi configuration, I also want to change the SSID and password. I know how to do that thing under the Oreo device. Can anyone help me get the same result in Oreo.

Answer 1

ONLY POSSIBLE IF YOUR APP IS RUNNING AS SYSTEM APP

In that case, I'm able to do this by using the below class:

it's not working it throw exception "java.lang.SecurityException: App not allowed to read or update stored WiFi AP config (uid = 10495)" – Afflux

Method getConfigMethod = manager.getClass().getMethod("getWifiApConfiguration"); works below the oreo version only – Afflux

@Afflux indeed it's need some permissions <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" /> <uses-permission android:name="android.permission.WRITE_SETTINGS"></uses-permission> <uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" /> <permission android:name="android.permission.OVERRIDE_WIFI_CONFIG" android:protectionLevel="signature|privileged" /> It's working for me on system app – Tagmeme

how can i define my app as system app? – Afflux

It can only possible if you are having configuration pemx509 and pk8 files to sign your apk – Tagmeme

configuration pemx509 and pk8 files ? What does it actually means and How can I get this ? – Meganmeganthropus

@Meganmeganthropus you can only do all this if your app is a system app, an app can only be a system app if it is placed on the ROM, and from the ROM vendor you can get this keys. – Tagmeme
