Building the OneSignal Xamarin.Android Binding

• Clone OneSignal-Android-SDK.
• Build the Android SDK Framework using

gradle assemble

• Import onesignal-main.aar from there into OneSignal.Android.Binding's Jars folder.
• Build the binding!
• Import the resultant binding OneSignal.Android.Binding.dll in your Xamarin.Android application.

Building the OneSignal Xamarin.iOS Binding

• Clone OneSignal-iOS-SDK.
• Build the iOS SDK Framework in Xcode.
• Using the Objective Sharpie tool, generate ApiDefinitions.cs and StructAndEnums.cs targetting iPhone OS 9.2.

sharpie bind -framework iOS_SDK/Framework/OneSignal.framework -sdk iphoneos9.2 -namespace Com.OneSignal.iOS

• Add the generated ApiDefinitions.cs, StructAndEnums.cs, and the OneSignal library (from iOS_SDK/Framework/OneSignal.framework/Versions/A/OneSignal) into the OneSignal.iOS.Binding.
• Rename the OneSignal library to OneSignal.a to clearly denote it as a static library.
• In ApiDefinitions.cs, make the following changes:
  • Remove using OneSignal;
  • Remove all Verify references.
  • Change ONE_S_LOG_LEVEL references to OneSLogLevel.
• In OneSignal.linkwith.cs, change [assembly: LinkWith ("OneSignal.a", SmartLink = true, ForceLoad = true)] to [assembly: LinkWith ("OneSignal.a", SmartLink = true, ForceLoad = true, Frameworks="SystemConfiguration", LinkerFlags="-ObjC")].
• In StructAndEnums.cs, change nuint to ulong.
• Build the binding!
• Import the resultant binding OneSignal.iOS.Binding.dll in your Xamarin.iOS application.
