- Android Studio 4.0.1
- gradle-wrapper.properties: distributionUrl=https://services.gradle.org/distributions/gradle-4.4-all.zip
- build.gradle:
dependencies { classpath "com.android.tools.build:gradle:3.0.0" // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } When assembling the release apk, it fails with an error:
Warning: Exception while processing task java.io.IOException: Can't read [C:\Users\derek_y\AppData\Local\Android\Sdk\platforms\android-30\android.jar] (Can't process class [android/annotation/Nullable.class] (Unsupported class version number [53.0] (maximum 52.0, Java 1.8))) :app:transformClassesAndResourcesWithProguardForRelease FAILED
FAILURE: Build failed with an exception.
Why is android-30\android.jar requiring Java version 53.0 (Java 9)? Android Studio 4.0.1 is not supporting Java 9 right?
P.S. I tried
- gradle-wrapper.properties: distributionUrl=https://services.gradle.org/distributions/gradle-6.1.1-all.zip
- build.gradle:
dependencies { classpath "com.android.tools.build:gradle:4.0.1" // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } But then running the compiled apk triggered another error which is from a third-party SDK:
java.lang.VerifyError: Rejecting class a.b.c because it failed compile-time verification I want a quick fix, and requesting the third-party to update takes time, so this is not helping at this moment. Or anyone could explain why this VerifyError occur and how to fix it?
Thank you a lot.
