Create android framework.jar only

Question

By adding some debugging information to androd.opengl.GLSurfaceView , I want to rebuild framework.jar only in the Android source tree. I made mm in $ ANDROID_ROOT, but that would also create applications, and some applications could not compile, but I was not worried about the applications. How could I only create framework.jar ?

In addition, it was pointed out in build/core/main.mk that incrementaljavac could speed up compilation. How can this flag be used here?

Thanks.

OK

mm command in framework/base will do the job, however it compiles both framework.jar and framework-ext.jar.
