Android android.permission.SEND_SMS not working [duplicate]

Question

I'm trying to send a SMS from my emulator to the second emulator

The main problem is that Android android.permission.SEND_SMS is not working probably.

I'm not sure is the problem because I have the latest SDK installed or what ?

I get the following expectation error that I don't have android.permission.SEND_SMS.

Since I'm using API 23 , I fixed it just by adding the request permission to my activity

ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.SEND_SMS},1);
