Having trouble synching gradle when implementing PebbleKitAndroid2

[jstevensog]

I am using Android Studio 2022.3.1 Patch 3 which is sued by the xDrip+ developers.
When I implementation("com.github.pebble-dev.PebbleKitAndroid2:client-java:4acc0485a1") instead of implementation 'com.getpebble:pebblekit:4.0.1', I get an error:
Null extracted folder for artifact: ResolvedArtifact(
componentIdentifier=com.github.pebble-dev.PebbleKitAndroid2:client-java:4acc0485a1,
variant=com.github.pebble-dev.PebbleKitAndroid2:client-java:4acc0485a1variant releaseVariantReleaseApiPublication,
variantName=null,
artifactFile=C:\Users\jstev.gradle\caches\modules-2\files-2.1\com.github.pebble-dev.PebbleKitAndroid2\client-java\4acc0485a1\3cc34b06e3d58151f20be7c6ca5c736c8a4ef21b\client-java-5e7b8e3.aar,
isTestFixturesArtifact=false,
extractedFolder=null,
publishedLintJar=null,
dependencyType=ANDROID, isWrappedModule=false,
buildMapping={current_build=C:\Users\jstev\StudioProjects\xDrip-plus}
)

I have inbvalidated the caches etc to no avail. The files are in the Gradle cache ready to go, but Android Studio appears not to be able to extract client-java-4acc0485a1.aar
Any advice on how to resolve this would be appreciated. I have not looked at xDrip+ code for 10 years, and am limited to this version of Android Studio to develop new Pebble integrations and resolve other issues for all the new Pebble models.

Is the aar in your cache identical to the https://jitpack.io/com/github/pebble-dev/PebbleKitAndroid2/client-java/4acc0485a1/client-java-4acc0485a1.aar?

[jstevensog]

Yes, they are identitcal. I am concerned that the older Android Studio, or older Gradle are the issue with extracting it.

[matejdro]

It certainly appears so. Does building from the command line (gradlew assemble) work?

[jstevensog]

TBH, I am not expert on Android development or gradle. When I try to run .\gradlew assemble (yes, Windoes machine) in the project root it complains that JAVA_HOME is not set and I have no idea how to set it correctly. Newbie problem ;)

I think this should help https://stackoverflow.com/a/52740410

Thanks for the tip, but no matter what I set the JAVA_HOME to, it is telling me it is invalid.
I have set it currently as follows:
Name Value

---

JAVA_HOME C:\Program Files\Android\Android Studio\jbr\bin;

And "where java" shows me no other java exists in my path.

If this were C or pretty much anything else, I would be fine. But Java has never been something I have gotten under the hood with.

BTW, what is the minimum Android Studio version you would expect to be able to use PebbleKitAndroid2?

[matejdro]

I think the error above is not complete. It only shows the symptom, not the cause.

One possible cause could be jetifier: https://issuetracker.google.com/issues/225025703#comment10 . Could you try removing enableJetifier=true from the gradle.properties?

Other than that, we would need full logs to proceed. I think the best way to do it, would be through command line build. Can you try installing JDK 21 and point java home to that?

[jstevensog]

Well, I guess I have had some success. Removing enableJetifier=true from gradle.properties at least fixes the sync issue I was having. Thanks. Now I will continue to replace all the old PebbleKitAndroid code with the v2 code. Thanks for the assistance. Will keep you posted if anything else crops up. Cheers
