Running Android Studio Volley in different API levels

The app I made ran on different API levels but the volley library only works API level 26.

I was puzzled when I can't login in the app using my phone (android 9) but a later model works just fine. I found out that I can only login in Android 8 phones (API level 26). I tested multiple virtual devices with different API levels and API level 26 let's me login and the rest just doesn't work. I was wondering how can I make volley library work on API level 26 and higher.

Edit: It was a big mistake for me but I now enabled the log for errors and I found these.
