You need to change to Java 7 in the Java code or you must need to change in B4A to 7 too?. I changed to Java 7 in B4A too and I got this error

B4A :: Java 7
Eclipse:: Java 7

B4A version: 5.50
Parsing code.  (0.00s)
Compiling code.  (0.09s)
Compiling layouts code.  (0.00s)

Compiling debugger engine code.  Error
Error: Could not find or load main class com.sun.tools.javac.Main

Use Java 8 with B4A.

Looks like you are wrapping a non-Android library.

OK, I use Java8 with B4A but my problem persist. I am compiling the java code in eclipse with JDK 7

It looks like you are still compiling with Java 8.
