Find out which branches exist (both locally and remotely) and which one is active (marked with an asterisk) by executing the following:
% git branch -a
android
* android-mydevice
origin/HEAD
origin/android
origin/android-mydevice
origin/android-mychipset
To only see local branches, omit the -a flag.
To build the kernel, execute:
% make -j4
When building for a particular product, it's often useful to have minor variations on what is ultimately the final release build. These are the currently-defined build variants:
eng
|
This is the default flavor. A plain make is the same as make eng.
Installs modules tagged with: eng, debug, user, and/or development.
Installs non-APK modules that have no tags specified.
Installs APKs according to the product definition files, in addition to tagged APKs.
ro.secure=0
ro.debuggable=1
ro.kernel.android.checkjni=1
adb is enabled by default.
|
user
|
make user
This is the flavor intended to be the final release bits.
Installs modules tagged with user.
Installs non-APK modules that have no tags specified.
Installs APKs according to the product definition files; tags are ignored for APK modules.
ro.secure=1
ro.debuggable=0
adb is disabled by default.
|
userdebug
|
make userdebug
The same as user, except:
Also installs modules tagged with debug.
ro.debuggable=1
adb is enabled by default.
|
If you build one flavor and then want to build another, you should run make installclean between the two makes to guarantee that you don't pick up files installed by the previous flavor. make clean will also suffice, but it takes a lot longer.
