build android framework.jar only

Question

Having add some debug information to androd.opengl.GLSurfaceView , I want to rebuild the framework.jar only in the android source tree. I did a mm in $ANDROID_ROOT but that would build the apps as well and some apps failed to compile but I did not bother with the apps.How could I build the framework.jar only?

Furthermore, in the build/core/main.mk,incrementaljavac was said to be able to speed up the compilation. How that flag could be used here?

Thanks.

Answer 1

OK.

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