For example, this allows a plug-in to modify an Android APK AndroidManfiest.xml file or an IOS IPA plist file. While UPL is a general system for modifying and querying XML it is specifically used to allow plug-ins to effect the global configuration of the package that they are a part of. I am going to assume you are familiar with it, if not it’s basically: Unreal Plugin Language will help us to achieve both of these goals. What about the other libs that have dependencies on old support libs? See the jetifier lines above? Jetifier takes care of that. Modify the java source files before the build begins to replace the imports of classes that use the old support libs.Append eAndroidX=true and android.enableJetifier=true to gradle.properties file in the intermediate project before the build begins.What the migration does are basically two things that we must automate: The problem is that every time you launch the game from the editor the intermediate Gradle project gets overwritten and it’s not practical to ask our clients to do so. With Android Studio 3.2 and higher, you can migrate an existing project to AndroidX by selecting Refactor > Migrate to AndroidX from the menu bar. If you are looking for a quick and dirty approach could simply run the AndroidX migration in Android Studio after opening this intermediate project. When you build an Android project it creates and intermediate Gradle project in the project folder in YourProjectName\Intermediate\Android\APK\Gradle and then builds it to create the APK.
This was a complete blocker that urged us to find the solution.Īn issue with older Vungle SDK The Solution Up until the point when one of our client’s apps has been rejected from Google Play for using the outdated Vungle SDK as a part of mediation in our AdMob Plugin. You could, however, say - “Hey, what’s the big deal, why don’t you just use the older versions of SDKs that still use old support libs?”.
And all the newest versions of these SDKs use AndroidX and require it to be enabled in the project. We enable developers to use native mobile AdMob, Firebase, Facebook, and other SDKs. We in the business of developing mobile native plugins for the Unreal Marketplace.
Why do we need it?Īt the time of writing, the latest Unreal Engine (4.25.3) still uses old Android support libraries instead of AndroidX. In this article, I will describe how to make the plugin handle the automatic upgrade of the Android Unreal Engine project to AndroidX. How to force the Unreal Engine Android project to use AndroidX?
