Meticulus's Android Bin Tools

Description

Various tools and prebuilts I use in the course of developing and build android roms on UbuntuMate 14.04 LTS.

Patch System

The patch system works by having a patchset in the $devicetree/patches. In this folder is a "common" folder and various "$rom" folders. Each recreates the directory structure from the "$TOP" of the AOSP source with corresponding patches inside. The "patcher" tool will find all these patches and apply them to the correct repo. Other tools are there to help make it easy to create and modifiy patches quickly. Each "$rom" folder should hold patches that are specific to that rom. I.E. lineage folder for lineage and slim for slim. The "common" folder is used for patches that apply to all roms. This makes it possible to build several AOSP based ROMs using the same branch of the same tree.

EXAMPLE: https://github.com/Meticulus/android_device_huawei_hi6250/tree/master/patches

NOTE: All patches should be cleared before repo sync'ing. Use "clearpatches". Then "patcher" to re-apply after repo sync'ing.

License

Any tools written by me are subject to the AGPL. Other prebuilt tools are subject to their own licenses.

Setup

I keep these in ~/bin and add them to the PATH variable.

git clone https://github.com/Meticulus/android_bintools -b master ~/bin

Add ~/bin to the PATH variable.

echo PATH=~/bin:$PATH

For a more permanent solution:

echo "PATH=~/bin:\$PATH" >> ~/.bashrc

Session Setup

Before using these tools you should have the typical build android build environment setup.

. build/envsetup.sh
lunch your_buildtarget-buildvariant

Workflow

Create a patch

cd to the repo you wish to patch and clear the repo of all patches first.

clearrepo

Make your modifications and then create the patch

makepatch

Re-patch the repo including the patch you just created

patchrepo

Fix a patch
