I’m trying to build on Android, with UE 5.3 from the engine source.
I’ve got my setup, and it’s worked for 5.2 and back but seems to run into an issue with Gradle in 5.3.
Could not resolve com.android.tools.build:gradle:7.4.2.
This was the only informative error message. It’s weird though because the logs indicate that it’s trying to use Gradle 7.5, but I’ve got nothing on my machine that has installed Gradle 7.5 nor specifically lists Gradle 7.5.
I’ve run the SetupAndroid.bat files, checked every bit of documentation and googled my issue into the ground. I’ve uninstalled and reinstalled Android Studio multiple times, checked every environment variable.
I’m at a complete loss, especially since I’ve been able to successfully build in 5.2, all the way back to 4.26.
Get the same error using source build from ue5-main, version: [c55a60b]

I did actually manage to get it building.
The Android documentation going into 5.3 will need quite a bit of overhauling to explain the bigger issue.
In the SetupAndroid.bat, it’s actually now setting pretty much all of the environment variables for you instead of you having to do them yourself, with the exception of your ANDROID_HOME is set.
The default setup will only support Android 32 and newer. Because of this, you will need to install Java 11 and make sure that JAVA_HOME is pointing to that location.
Mine is
C:\Program Files\Android\Android Studio\jbr
. Also, I know the Android setup page tells you do change SetupAndroid.bat to use the path to 8.0 instead of latest, but make sure you leave it on latest.
You can run the SetupAndroid.bat with parameters for older versions if you’d like, and if you do, make sure your JAVA_HOME is pointing to the correct place.
I hope this helps.
My 5.2 setup did not work going into 5.3. But my environment is also a little messy as I have to constantly move between UE5 and UE4 and there are things that just don’t get along. 5.2 is when the SetupAndroid.bat changed, but I guess in some cases it played just fine because the Gradle plugin requirements?
So I changed the SetupAndroid.bat to latest instead of 8.0
In AndroidStudio I installed Command-line Tools (latest) 11.0
SDK Manager/SDK Tools/ Also needed to check Show Package Details
Don’t know if that step is necessary to be honest
