StrictMode is a mechanism provided by the Android development platform to help developers discover and solve potential performance issues and violations during the development process. It helps developers identify time-consuming operations, network requests, database operations, and other code that may cause performance issues, providing warnings or exception messages in a timely manner.<\/p>\n

How to use StrictMode is as follows:<\/p>\n

    \n
  1. In the main thread of the application, you can utilize StrictMode by using various static methods of the StrictMode class.<\/li>\n
  2. Set the thread policy using StrictMode.setThreadPolicy() to monitor time-consuming operations on the main thread.<\/li>\n
  3. Set the virtual machine policy using StrictMode.setVmPolicy() to detect memory leaks, file operations, and more.<\/li>\n
  4. You can set the detection policy for StrictMode by following these methods:<\/li>\n
  5. detectAll(): identify all issues.<\/li>\n
  6. detect custom slow calls: identify operations that take a long time to execute.<\/li>\n
  7. detectNetwork(): check network connection.<\/li>\n
  8. Detect disk reads: detects disk read operations.<\/li>\n
  9. detectDiskWrites(): Detecting disk write operations.<\/li>\n
  10. penaltyLog(): write warning information into the log.<\/li>\n
  11. penaltyDeath(): throw an exception to halt the program.<\/li>\n
  12. Call the set method of StrictMode in the appropriate location in the application, such as in the onCreate() method of the Application.<\/li>\n<\/ol>\n
    public<\/span> void<\/span> onCreate<\/span>()<\/span> {\r\n    super<\/span>.onCreate();\r\n    if<\/span> (BuildConfig.DEBUG) {\r\n        StrictMode.setThreadPolicy(new<\/span> StrictMode<\/span>.ThreadPolicy.Builder()\r\n                .detectAll()\r\n                .penaltyLog()\r\n                .build());\r\n        StrictMode.setVmPolicy(new<\/span> StrictMode<\/span>.VmPolicy.Builder()\r\n                .detectAll()\r\n                .penaltyLog()\r\n                .build());\r\n    }\r\n}\r\n<\/code><\/pre>\n
    Developers can use StrictMode to identify potential performance issues during the development phase and improve them to enhance the performance and user experience of the application. It is important to note that StrictMode should only be used during the development and testing phases, and should be disabled in the release version to avoid unnecessary interference for users.<\/p>\n","protected":false},"excerpt":{"rendered":"
