I’d like to know if it’s necessary to rebuild and redeploy my whole AOSP tree after I make modifications to Java source files in framework.jar.
I have working (buildable) trees os ICS and JellyBean and can successfully install them onto my virtual machine.
I’m aware about CCACHE to help speed up builds, and I imagine if I’m modifying C/C++ code then a rebuild and reinstall of the whole tree is my only option.
However, for small changes, such as one of the view or activity source files, is there a quicker method available? A rebuild and reinstall each time makes development a slow and painful process. I’m sure vendors and what not have faster methods at their disposal.
I had no luck with this method:
Running mm in frameworks/base (compiled successfully) and replacing the framework.jar/framework.odex files on the running system.
Rebooted – but then the system hung before the boot screen.
I tested my code by rebuilding the whole image and reinstalling and that image booted okay.
For me I discovered the following way. However, I develop for a real device, thus, maybe my approach is not applicable for your case.
- As you do,
mmm frameworks/base -jN(if you want to add changes
also to image and build image you can add
snodbut this will slow
down the build process)
- Run adb remount (to make system image writable) – you need to do
this only once after you reflash all the device.
adb sync system
