Hello everyone.
I tried to compile some program and got this error message from the compiler:
Signing package file (debug key). Error
java.lang.UnsupportedClassVersionError: com/android/apksigner/ApkSignerTool has been
compiled by a more recent version of the Java Runtime (class file version 53.0), this version
of the Java Runtime only recognizes class file versions up to 52.0
Having read similar topics on this forum I learnd that it needs to update SDKs.
But trying to do so I learned that my SDK manager doesn’t sees any versions of SDK higher then 29. And B4A says that it needs SDK of version 30 or 31.
I have installed on my system (Windows 7 32bit):
Installed SDK platforms: android-14, android-27, android-29
Installed JDKs: jdk-8u201, jdk.80_311
Can anyone help me with this problem?
