Question

I have compiled Android source code already (which I downloaded using GIT)
and I am being editing the source code of an Application for testing on Emulator
each time I wanna see results I have to re-Compile the source code again using ‘make’
I am pretty sure that there is a way to partly-compile the image

Notes: I use Ubuntu ,and Android Eclair source

Answer 1

you can use this command
mmm packages/apps/yourApp
or whatever the path of your APP is

Assuming that :

1. your working directory is the same of your source files (which YOU downloaded using GIT)
2. you already run these commands source build/envsetup.sh and lunch 1

Next step: to update your emulator to see your changes
Run these commands
adb remount
adb sync

Finally, an advice , using Eclipse will make life easier for you
