Why is it not possible to compile with JDK 8

[Jacques]

Hello,

I tried to run the mapsforge-master project from android studio to a virtual android emulator but it gives an error and couldn't be compiled with JDK 8. Why is that?

I tried to point to openJDK 7 on android studio project structure window, but seems android studio doesn't recognize openJDK.

Here are the errors:

Error:com.android.dx.cf.iface.ParseException: bad class file magic (cafebabe) or version (0034.0000)

 

Error:Execution failed for task ':Applications:Android:Samples:transformClassesWithDexForOldpermissionsDebug'.
> com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/usr/lib/jvm/java-8-oracle/bin/java'' finished with non-zero exit value 1

Thanks

Android had mostly Java 6 compliance and Java 7 support was added from Android KitKat SDK era.

"Added support for Java 7 language features like multi-catch, try-with-resources, and the diamond operator. These features require version 19 or higher of the Build Tools. Try-with-resources requires minSdkVersion 19; the rest of the new language features require minSdkVersion 8 or higher."

There is not any official recommendation for Java 8 yet.

About AS look here:

Thanks.

The issue has been resolved by installing oracle JDK 7 and pointing out it on AS. 

Anyway my new android projects in AS have had no problem with JDK 8 and are compiled via that.

Regards
