  • which aspect of golang proposal solve?
  • it has potencial reduce binary size of apk (binary of android) it also can reduce call java, but it is not mainly goal (benefit) and in practical maybe unmeasured, although it seems like avoid dalvik and it's GC, it couldn't have effect to go bind , it can brings more control and better debug ...

the gomobile use java code which use NativeActivity and load binary (.so), which has of course advantage too, but it is big binary size (pure C estimate 1-2MB) and at debug it is terible ... so The discusion and proposal is: there is technology, which allow reduce binary size to 25-45KB(at C side), better debug and have more control on code (it is without java code)..., so why do not use it in gomobile?

Thanks. This doesn't sound like it has to be a proposal, so taking it out of the proposal process.
