When you reinstalled the SDK, did you restart your computer between uninstalling and reinstalling the SDK? This can help ensure that all of the original installation is gone. Also, are you installing the SDK provided with the editor or one downloaded online?
Can you show a screenshot of exactly what you’re installing through the SDK manager? Please try installing through the suggested method in our documentation, by installing the CodeWorksforAndroid-1R5-windows.exe located in your engine installation at Epic Games\4.15\Engine\Extras\AndroidWorks\Win64
First thing - when you change something crutial in Java - delete the E:\Project\UNreal\RisekingdomProject\Intermediate\Android\ directory. Unreal has nasty problems with cacheing and sometimes You have to clear the cache yourself. I’m usually do it every build, just in case.
Second - always use the recommended codeworks, unless You are really good in modifying the engine and in Android overall You are using 1r5 now - so good.
Third - download all of the extras from Android SDK Manager. It doesn’t weight much, but for instance - I can see You doesn’t have Google Play Services downloaded which might be an issue.
Now, from the log I can see that there is an issue with extracting google play services from AAR:
Error: E:\Project\UNreal\RisekingdomProject\Intermediate\Android\APK\JavaLibs\play-services-ads-9.2.0 is not a valid project (AndroidManifest.xml not found).
Most of the JavaLibs are the directories extracted from AAR files located somewhere here:
