Hello, I'm sorry you're experiencing issues. Please understand that while we try our best sometimes our games don't work for all Android devices for various reasons including the fact that there are a large amount of different models/devices as well as versions of Android being run out there. Some things you can try are below.
Please try to make room/free space up in root on your Android and then reinstall. You must have a large amount of free space on your device if you don't already.
If that doesn't work then another option is to try using JoiPlay on your Android device with the PC version I believe.
