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, we recommend utilizing android-latest-release instead of aosp-main. The android-latest-release manifest branch will always reference the most recent release pushed to AOSP. For more information, see Changes to AOSP.

DeviceSettingChecker

public DeviceSettingChecker ()

Public methods

postExecutionCheck

public StatusCheckerResult postExecutionCheck (ITestDevice device)

Check system condition after test module execution. Subclass should override this method if a check is desirable here. Implementation must return a boolean value to indicate if the status check has passed or failed.

Parameters
`device`	`ITestDevice`: The `ITestDevice` on which to run the checks.

Returns
`StatusCheckerResult`	result of system status check

Throws
`DeviceNotAvailableException`

preExecutionCheck

public StatusCheckerResult preExecutionCheck (ITestDevice device)

Check system condition before test module execution. Subclass should override this method if a check is desirable here. Implementation must return a boolean value to indicate if the status check has passed or failed.

It's strongly recommended that system status be checked after module execution, and this method may be used for the purpose of caching certain system state prior to module execution.

Parameters
`device`	`ITestDevice`: The `ITestDevice` on which to run the checks.

Returns
`StatusCheckerResult`	result of system status check

Throws
`DeviceNotAvailableException`
