    MMkvSPUtils

    A library or class used for managing shared preferences or lightweight key-value storage in an Android application.

    Initialization of MMkv

    Study Notes

    Lifecycle Events

    • Application lifecycle events, including onCreate (initialization)
    • MMkvSPUtils (likely a module for managing data) functions (mmkv init, user info, privacy status)
    • StorageUtils for retrieving file directories, and potentially PDF file initialization
    • getExternalFilesDirs accesses storage
    • DirtyStrokeHandler manages/processes data, possibly related to strokes or drawing (multiple threads used)

    System Level Details

    • LifeCycle level 80, indicating position in the cache
    • Process termination may be influenced by this LRU cache position
    • Potential implications for process priority and termination

    Specific Data Points

    • Various dates and timestamps recorded (e.g., 2024-11-16, 07:35:50)
    • Version numbers (e.g., 2.9.9.8)
    • Thread information (e.g., Thread: 309)
    • File paths (/storage/emulated/0/Android/data/...)
