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

java.lang.reflect.InvocationTargetException at java.lang.reflect.Method

Permission is not your problem. You need something like this code :

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (!Settings.System.canWrite(getApplicationContext())) {
    Intent intent = new Intent(Settings.ACTION_MANAGE_WRITE_SETTINGS, Uri.parse("package:" + getPackageName()));
    startActivityForResult(intent, 200); //You need a callback for activity result so that check if user enabled this feature, go for starting hotspot (google for it)
} else {
    // Do your stuff about starting hotspot (in network thread)
}

}
