Android 6.0.1 couldn't enable wifi hotspot programmatically

Question

When I tried to enable wifi tethering from the following code it throws the exception

Answer 1

Set target SDK version 21 and ask for write_settings permission in your activity. Also add android.permission.WRITE_SETTINGS permission in manifest.

if (ActivityCompat.shouldShowRequestPermissionRationale(this,
                Manifest.permission.WRITE_SETTINGS)){

}else {
    ActivityCompat.requestPermissions(this,
            new String[]{Manifest.permission.WRITE_SETTINGS},
            121);
}
