Cannot Resolve Symbol 'request_code_read_contacts

I'm trying to request permission to access the ringer using this: if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && ActivityCompat.checkSelfPermis

Solution 1:

If you copied the code above from answer in this topic then just initialize it with 1 and add this method in your code

publicvoidonRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults){

    switch (requestCode){
        case REQUEST_CODE_READ_CONTACTS:
            if(grantResults.length>0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){
                READ_CONTACTS_GRANTED = true;
            }
    }
    if(READ_CONTACTS_GRANTED){
        loadContacts();
    }
    else{
        Toast.makeText(this, "Allow permission in settings", Toast.LENGTH_LONG).show();
    }
}

Solution 2:

The value is a request code that you have to define yourself.

privatestaticfinalint REQUEST_CODE_READ_CONTACTS = 99; // Can be any value >= 0

You can use it to determine which permission request the user has responded to in the onRequestPermissionsResult() callback by checking for the matching value.

publicvoidonRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults){
    switch (requestCode) {
        case REQUEST_CODE_READ_CONTACTS:
            // Do your thingbreak;
        case ...
    }
}
