I have WEB VIEW app and I ask for help. I have the following scripts: SharedPreference.java, FirebaseInstanceIDService.java and login.php, where is login.php hosted on the server.
I need to send the recorded token from SharedPreference to the MySQL database using the login.php script that contains the session.
When I delete the session from login.php, the token is record to the MySQL, when I return the session to the login.php the token is not recorded in the database.
Where am I wrong? Please Help.
MainActivity.java
SharedPreference.java
FirebaseInstanceIDService.java
login.php
