Hi guys,
I don't know if this thread is still active, but I spent some hours
trying to make the EMMA instrumented code generation works.
I actually came pretty close of getting it, I think. You can use the
EMMA_INSTRUMENT:=true on the project Android.mk file to turn on the
EMMA instrumentation for that project. Everything seems to work, but
at the end I get a bizarre error on Calendar Tests:
target Java: Calendar (out/target/common/obj/APPS/
Calendar_intermediates/classes)
Note: Some input files use or override a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
EMMA: processing instrumentation path ...
EMMA: instrumentation path processed in 703 ms
EMMA: [119 class(es) instrumented, 11 resource(s) copied]
EMMA: metadata merged into [/work/android3/out/target/common/obj/APPS/
Calendar_intermediates/coverage.em] {in 51 ms}
Copying: out/target/common/obj/APPS/Calendar_intermediates/classes.jar

UNEXPECTED TOP-LEVEL EXCEPTION:
com.android.dx.cf.code.SimException: local variable type mismatch:
attempt to set or access a value of type java.lang.String[] using a
local variable of type java.lang.String. This is symptomatic of .class
transformation tools that ignore local variable information.

Really strange error. I'll keep trying to find out how to fix this.
Thanks
