- A new
PushSDKDependencies.xmlfile is generated for them to use.
InsertPushNotificationDependenciesIntoGradleScriptwill not run to prevent duplication from gradle.
- Fixed errors appearing in the Editor Play Mode due to platform specific classes instantiating.
- Added necessary post notification permission to manifest.
