Answer 1

You need to add the permission into manifest xml:

AND, you need to ask for the permission at runtime. Until android 6, the permissions were granted automatically on installation. In android 6 and above, you can install application and not grant the permission. You can use this function in your activity class:

private void requestSmsPermission() {
    String permission = Manifest.permission.RECEIVE_SMS;
    int grant = ContextCompat.checkSelfPermission(this, permission);
    if ( grant != PackageManager.PERMISSION_GRANTED) {
        String[] permission_list = new String[1];
        permission_list[0] = permission;
        ActivityCompat.requestPermissions(this, permission_list, 1);
    }
}

this - your activity.
