This Gradle plugin helps make the OneSignal Android SDK compatible with your Android Studio / Gradle project. It automatically fixes and notifies you of required changes to make the OneSignal SDK compatible with your app.

This repository has been deprecated and will no longer be maintained. The OneSignal gradle plugin for Android was designed to (1) ensure the compileSdkVersion is 31 or higher and (2) ensure (mostly) firebase dependent libraries in use by the app & onesignal are compatible. The dependent library compatibility problem has been less of an issue, making the plugin less useful. However inclusion of the plugin itself can sometimes cause side-effect issues during build. As a result, including the OneSignal Gradle plugin is no longer considered standard when configuring an app to use the OneSignal SDK.

If you experience issues related to what this plugin was designed to solve, please open a question in the onesignal-android-sdk repository.

1. In your root build.gradle, under buildscript, add the following 2 new lines to your existing repositories and dependencies sections

buildscript {
    repositories {
        // ...
        gradlePluginPortal()
    }
    dependencies {
        // ...
        // OneSignal-Gradle-Plugin
        classpath 'gradle.plugin.com.onesignal:onesignal-gradle-plugin:[0.14.0, 0.99.99]'
    }
}

2. Add the following to the top of your app/build.gradle

apply plugin: 'com.onesignal.androidsdk.onesignal-gradle-plugin'

3. Android Studio - Sync gradle
4. Clean and rebuild

• Automatically aligns versions of module dependencies under the same group. This fixes compile and runtime errors due to mismatched interdependencies. Applies to the following libraries:
  • com.google.android.gms
  • com.google.firebase
  • com.android.support
• Ensures com.android.support is never higher than compileSdkVersion
• Ensures a compatible OneSignal SDK version for the targetSdkVersion you're using
• Ensures new enough OneSignal SDK is included when com.android.support is upgraded
• Calculates intersecting range of 2 version ranges
  • Including backwards capability with Gradle 2.14.1
• Future: Other warnings and checks specific to OneSignal such as app_id and notification icons

• Recommend using AGP 3.0.0 or newer (Android Gradle Plugin) and Gradle 4.1 or newer.
  • Compatible with Gradle 2.14.1+ and AGP 2.2.3+
  • Tested up to Gradle 7.0.2 and AGP 4.2.1
