Code coverage for monkeyrunner using JaCoCo

[jeffcomlin]

I tried updating the profile for monkeyrunner as below. But the app crashes when the test runs and this happens only on instrumented build.

I am looking for some insight on this.

Thanks,
Jeff

Error:

W/dalvikvm( 6413): VFY: invoke type does not match method type of Lcom/abc/xyz/model/Article;._getPartsMap

Useful comment from the link:

I figured it out!

Turns out that the methods which were not getting executed from the
constructor were private and final. However, the byte-compiler of
Rhino was emitting invoke-virtuals in the constructor for those
methods. dx faithfully converted them and retained their invoke-
virtual character. I changed them to invooke-direct with the effect
that the compilation now works! Thanks for all your help!

My experiment:

Changed _getPartsMap from private to public.
It stopped complaining about _getPartsMap and complained about the next. I change the next method to public and it went on to the once after that.

I don't think making these methods public is a solution, but I am hoping it might have some clues.

Rest of the error message: (Below is the error message I see after Dalvikvm error, mentioned above)

@stephanenicolas Could you please take a peek at this? If you can share some suggestions or pointers, I will definitely look into this further.
