Answer 1

No need to Use getToken() new token already returned by onNewToken argument

@Override
public void onNewToken(String refreshedToken) {
    // No need to assign refreshedToken with getToken,
    // this method called when token refreshed then use returned refreshedToken directly,
    // use `instanceIdResult.getToken()` described below when you need to use token later throw app usage.

    // refreshedToken = FirebaseInstanceId.getInstance().getInstanceId().getResult().getToken();
    Log.d(TAG, "Refreshed token: " + refreshedToken);
    storeToken(refreshedToken);
}

getToken(); is also deprecated

Get Token in your Activity : .getToken(); is also deprecated if you need to get token in your activity then use as following:

FirebaseInstanceId.getInstance().getInstanceId().addOnSuccessListener( MyActivity.this,  new OnSuccessListener() {
     @Override
     public void onSuccess(InstanceIdResult instanceIdResult) {
           String newToken = instanceIdResult.getToken();
           Log.e("newToken",newToken);

     }
 });
