java.lang.RuntimeException: Unable to start activity ComponentInfo{com.razorTest.razorpayMe/host.exp.exponent.MainActivity}: java.lang.IllegalArgumentException: unexpected url

I have an expo app ejected to use ExpoKit, where I have followed the steps listed here to get react-native-razorpay integrated. My app when run with Android Studio throws the following error stack:

E/MQSEventManagerDelegate: failed to get MQSService.
I/Process: Sending signal. PID: 15077 SIG: 9
Application terminated.

Also, on running the example project using react-native run-android, I am getting this: ERROR: Could not find method implementation() for arguments [com.facebook.react:react-native:0.20.+] on project ':react-native-razorpay'.

I do not have any prior experience with native programming to make any calculated guesses, and couldn’t find a direction after a few hours of googling and trying. Please help!

@devautor Looks like this issue is because of some changes needs to be done in build.gradle file. Will check it at our end and update you soon.

@devautor By native I mean native - iOS and native-android modules and not react-native modules. Our package uses a native-iOS and Android framework as react-native supports it but not expo.
