Study Notes
Application Lifecycle Events
- Application initialization (
onCreate
) - Maintaining user information (
userInfo:false
,IS_FIRST_PRIVACY:true
,userToken:false
) - Loading PDF documents (
PDF pdf 初始化成功 version:9.0.0.1127
) and potential reflection errors in accessing storage (StorageUtils, getReflectRootInPath: 反射获取失败
) - Utilizing file paths (
getExternalFilesDirs
) - Managing and updating notes data
- Optimization measures (using LRU cache and handling potential cleanup (
LifeCycle level=40
)) - Handling various events and thread activity
Note Management
DirtyStrokeHandler
threads manage note data (initial count, handling, and completion).StrokeUpgradeHandler
processes note updates and upgrade status.UpgradeManager
oversees note upgrade operations (pre-processing and counts).
Library Interactions
MMkvSPUtils
manages key-value storage (mmkv init
,user info
,IS_FIRST_PRIVACY
,userToken
).- StorageUtils handles file system interactions, potentially using reflection (
getReflectRootInPath
).
System Activities
- Application startup sequence, possibly across different devices based on tablet status (
isTablet
).
UI Interactions
BaseActivity
andSubscribeVipActivity
handling lifecycle events.- Operations like
onResume
andonCreate
are observed within these activities (BaseActivity.onCreate, BaseActivity.onResume
). PhoneNoteListActivity
manages list views and note details, demonstrating activity lifecycle and background operations.
Other Observations
- Specific error messages or warnings related to processing or system interactions are noted.
LifeCycle
levels provide insight into application status and related memory management.- Application state changes (e.g., foreground/background transitions and corresponding actions).
- Version information(
PDF version:9.0.0.1127
) is documented.
