AOSP–Make a Change and Push Code for Code Review

1. cd frameworks/native

2. upgautam@amd:/opt/aosp/frameworks/native$ repo start make_a_change .
Starting make_a_change: 100% (1/1), done in 0.102s
upgautam@amd:/opt/aosp/frameworks/native$ repo branch
*  make_a_change             | in frameworks/native


3. Edit: services/surfaceflinger/SurfaceFlinger.cpp
4. Find: void SurfaceFlinger::updateColorMatrixLocked() { .... }
5. Add "mClientColorMatrix = mat4(vec4{1.0f, 0.0f, 0.0f, 0.0f}, vec4{0.0f, -1.0f, 0.0f, 0.0f},
                          vec4{0.0f, 0.0f, -1.0f, 0.0f}, vec4{0.0f, 1.0f, 1.0f, 1.0f});" at the start of the body.
6. Build the code: m # you can run from this directory /opt/aosp/frameworks/native/services/surfaceflinger

If cuttlefish emulator is already running then update the build on the device

adb root
adb remount -R
adb root
adb sync
adb reboot

If not, simply starting an emulator should show your updated screen of the emulator. Reference: https://source.android.com/docs/setup/start

Push your code to google source (this is being AOSP contributor)

cd frameworks/native
git add .
git commit

Enter commit message repo upload

You will see synapsis something like this
