    Study Notes

    Error Handling

    • NameNotFoundException occurs when trying to access package information for an application
    • This exception is caught by the android.content.pm.PackageManager

    Package Management

    • ApplicationPackageManager is used to get package information
    • The getPackageInfoAsUser method is called to retrieve package information for a specific user
    • This method is called from the getPackageInfo method

    OAID (Open Advertising ID) Implementation

    • OAID is implemented using the SamsungImpl and MsaImpl classes
    • These implementations use the OAIDFactory class to create an instance of the OAID
    • The OAIDFactory class has methods c and a which are used to create the OAID instance
    • The DeviceID class is used to store the OAID instance

    Coroutine Scheduling

    • Coroutines are scheduled using the CoroutineScheduler class
    • The Worker class is used to run coroutines
    • The startState method is used to start the coroutine
    • The resumeWith method is used to resume the coroutine
    • The DispatchedTask class is used to dispatch tasks to the coroutine

    Kotlin Coroutines

    • Kotlin coroutines are used to implement asynchronous programming
    • The SynchronizedLazyImpl class is used to implement lazy initialization of coroutines
    • The BaseContinuationImpl class is used to implement the coroutine continuation
    • The CoroutineScheduler class is used to schedule coroutines
    • The Worker class is used to run coroutines
