Hello!
The facebook login window crashes the application on Android devices (Android 6 and 7 too)
The error is:
02-17 10:09:52.624: E/AndroidRuntime(13559): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.eclickmobile.tinygravity/com.facebook.FacebookActivity}: android.content.res.Resources$NotFoundException: File res/layout/com_facebook_activity_layout.xml from xml type layout resource ID #0x7f040019
It works on iOS
