Android : White screen of death on Facebook Login Android

I am completely stuck on this. I have tried absolutely everything, and searched and tried every answer on the internet. I have firbase login using facebook with javascript using cordova. I have inappbrowser installed, my Facebook app is set up with firebase callback. it allows me to enter credentials, and takes me to a blank white screen. Cordova is included, inappbrowser is included, hashkey is set up. Using latest libraryies. HELPPPP!!!
