Hi,

I got this during compile:

Dex: c:\android\android-sdk\tools\..\extras\b4a_remote\com\google\android\datatransport\transport-api\3.2.0\unpacked-transport-api-3.2.0\jars\classes    Error
Exception in thread "main" java.lang.UnsupportedClassVersionError: com/android/tools/r8/D8 has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

This is after installing resources_7_24.zip.

Can someone tell me what's wrong?

Kind regards,
André

You are probably using a lower java version than the jar you are using.

What java version are you using?

I guess it should be at least java 11
