Activate Tethering in Java:

private void activeTethering(){
    Intent tetherSettings = new Intent();
    tetherSettings.setClassName("com.android.settings", "com.android.settings.TetherSettings");

    startActivity(tetherSettings);
}

and in Kotlin:

private fun activeTethering(){
    val tetherSettings = new Intent().apply {
        setClassName("com.android.settings", "com.android.settings.TetherSettings")
    }

    startActivity(tetherSettings);
