Effective in 2026, to align with our trunk stable development model and ensure platform stability for the ecosystem, we will publish source code to AOSP in Q2 and Q4. For building and contributing to AOSP, use android-latest-release. The android-latest-release manifest branch will always reference the most recent release pushed to AOSP. For more information, see Changes to AOSP.

Git source editor
Stay organized with collections
Save and categorize content based on your preferences.
Overview
Git source editor (ci.android.com/edit) is a
browser-based tool for editing files in the Android Open Source Project (AOSP)
and uploading changes to Gerrit. It’s intended for making minor changes to a
small number of files, and provides a faster workflow than
downloading the Android source tree.
You should be familiar with the full process of submitting changes to AOSP using
Git, Repo, and Gerrit before using Git source editor.
When you edit a file using Git source editor, all of the work happens on your
local machine, until you upload changes to create a Gerrit changelist.
Caution: Because changes are stored only in the browser, they're lost if you
refresh or close the browser tab before uploading them.
Log in
Load Git Source Editor in a browser.
Click Log in to log in to your account.
Note: Make sure to log in with the account that has Gerrit privileges for the
branches you want to edit.
Figure 1. Login button
Edit files and changes
Git Source Editor has these main workflows:
Edit one or more files of your choice, in the branch that you choose.
Edit a change. When you edit a change, the result depends on who created the
change:
If you created the change, your Git Source Editor edits get patched into
the change as a new patchset.
If someone else created the change, your Git Source Editor edits create
a new change that you own, based on the change you loaded.
Load what you want to edit
Start an editing session by loading either a file or a change.
Load files
Enter the URL of the file you want to edit in the file/change path box
at the top of the page.
Sample file path:
https://android.googlesource.com/platform/build/+show/refs/heads/android17-release/Changes.md
Click Load file or change.
Figure 2. Loading a file or change
The file loads in the editor pane. The navigation pane to the left of the
editor pane is a file browser, which opens the repo, with your file
preloaded.
Figure 3. A file loaded into the editing pane
Note: Be sure to follow the remaining steps to submit your CL before refreshing
or closing your browser tab. Because the edited files are stored on your local
machine, refreshing or closing your browser tab here loses any changes you
made.
You can use the navigation pane to open more files within the same repo. If you
open multiple files, each file appears as a tab in the row above the editing
pane. Click a tab to open that file in the editing pane.
Figure 4. Tabs for loaded files
Load a change
Navigate to the change you want to edit by entering the URL of a Gerrit
changelist into the file/change path box at the top of the page (see
Figure 2).
Sample change link:
https://android-review.googlesource.com/c/platform/build/soong/+/1284176
The files in the change open in the editing pane (see Figure 3).
If the change includes multiple files, each file appears as a tab in the row
above the editing pane (see Figure 4). Click a tab to open that file in the
editing pane.
Note: Be sure to follow the remaining steps to submit your CL before refreshing
or closing your browser tab. Because the edited files are stored on your local
machine, refreshing or closing your browser tab here loses any changes you
made.
Make your edits
Edit files using the text editing pane. Files you edit appear in the Pending
changes list below the editing pane. If you accidentally close the tab of a file
with edits, you can reopen the file with the edits intact by clicking its name
in the Pending changes list.
Submit changes
You create and publish your change to Gerrit in Git Source Editor. Then you
track the change's approval in Gerrit.
Create and publish the changes
Follow this procedure to create and publish the changes you’ve made.
Click the appropriate button:
Click Create change if you're creating a new change.
Click Update change if you are updating an existing change.
A dialog box opens.
Figure 5. Create Change dialog box
Enter a change description, which will become the change description in
Gerrit. This description is required. If you are editing an existing change,
you can edit its description if you want.
Optionally, clear or select the Publish on create checkbox.
This box is selected by default.
If this box is selected when you create the change, the change is
immediately published to Gerrit. If the box isn't selected, the change is
uploaded to Gerrit but not published.
Click Create.
The change is uploaded to Gerrit. If you selected the Publish on create
checkbox, the change is also published in Gerrit. The change is linked in a
notification at the top of the screen.
Figure 6. Change created notification
Track change approval in Gerrit
Track change submission status directly in Gerrit, as you would any other
change.
Figure 7. Tracking change submission status in Gerrit
View file diffs
Select the Diff checkbox below the editing pane to view the diffs of edits
you’ve made to the file that’s active in the editing pane. This is useful when
changing a file and when editing an existing change.
Figure 8. Viewing file diffs
Revert files
You can revert changes from a single file or from all the files in the pending
changelist. Both revert options revert changes only in Git Source Editor. They
will NOT update the change in Gerrit.
Revert a single file
To revert a single file, click the X next to the filename in the Pending
changes list.
Figure 9. Pending changes section
Revert all files
To revert all files at once, click Revert all files below the editing pane.
Figure 10. Revert all files button
A popup dialog box opens. Click Revert all to revert changes in
all pending files, or click Cancel to retain the changes and continue
editing.
Figure 11. Revert all files confirmation dialog box
Edit a page directly from Android code search
You can open a file in Git Source Editor directly from
Android code search. This is helpful if you
need to locate the file before editing it.
Follow this procedure to edit a file directly from Android code search.
In Android Code Search (cs.android.com), navigate to the file you are
interested in editing.
Click Edit code.
Figure 12. Android Code Search Edit code button
Git Source Editor opens with the file preselected for editing.
Select the Git branch in which you want to edit the file from the Select a
git branch dropdown list, then click Pick branch.
Figure 13. Selecting a Git branch to edit
The file opens in the editing pane.
Continue editing as described in the Making Your Edits
section.
You can open additional files to edit as described in the
Loading files section
Resolve conflicts
To resolve conflicts:
In the Source Editor, navigate to the change. After the change is loaded,
the conflicting files are listed in the bottom portion of the screen.
For example, Figure 14 shows that theAndroid.pb file has a conflict.
Figure 14. Source editor conflict
Click a conflicting file. The file loads and shows conflicting blocks of
content in succession and within Git markers (<<<<<<< and >>>>>>>).
Figure 15. Source editor conflict markers
Fix the conflict by editing the file and manually removing the conflict
markers around the content you want to keep. Also, remove the content and
conflict markers for content you don't want to keep.
Click Create Change to create a new change. The Create Change
dialog appears.
Figure 16. Create change
Type a change description and click Create.
Send feedback
Use the bug button
in the top right corner to provide feedback about Git Source Editor.
