Starting March 27, 2025, we recommend using android-latest-release instead of aosp-main to build and contribute to AOSP. For more information, see Changes to AOSP.

After building Android, ensure that you can change the aconfig flag's value.
To change an aconfig flag value at runtime:
Ensure your device is running and connected to your development machine.
Check to see the flag's current setting:
adbshellaflagslist|greppackage.flagname
If the flag is enabled and your code is executing, continue with step 4 to
disable the flag. If the flag is disabled, skip to step 6 to enable your code.
Disable your code. From the command line, run:
adb shell aflags disable your.full.flag.name
For example, to disable the append_injected_content flag, run:
Check the status your code either by attempting to execute it on the device
or by rerunning the aflags list command again:
adbshellaflagslist|greppackage.flagname
If your code was enabled, it should be disabled. Conversely, if your code was
disabled, it should be enabled.
