jnjft Member Licensed User Longtime User May 26, 2017 #1 Hello! I began writing an app with b4a version 3.82 and upgraded to version 7.01 yesterday. When I load the code into v7.01 it is not possible to compile it, it stops with an error message ('... java.lang.UnsupportedClassVersionError: com/android/dx/command/Main : Unsupported major.minor version 52.0 ...) Can anybody help me please? Thank you
