washingtonbr I publish 3 app made in C2 to Google Play and Amazon using CocoonJS and they work very good. Check them out SynapseOne
Sometimes CoonJS has problem when using Physics plugin, but beside that it.s ok.
I usually compile to CocoonJS, resulting apk is 10 MB. I decompile it, delete one of the 2 cocoonjs library to make 2 version of the apk, one for armeabi and other for armeabiv7a, that way I got 5MB per apk and cover all the devices.
I am not using Eclipse for decompile/recompile/sign/zipalign, just some desktop shortcuts that I made that contain the parameters for the above actions.
P.S. Unfortunately apk compiled with CocoonJS does not work with android-sdk compiler. You must have a real device to test the resulting apk
