How Android devices display strings differently and the process of generating the build.prop.

In Android, the principles of how device strings are displayed and the generation process of build.prop are as follows:

1. Principle of String Display:
2. The way Android devices display strings is mainly related to language and region settings. Android will choose the appropriate string resource file to display based on the language and region set by the user. Each application has a default string resource file, usually stored in the res/values (default language) or res/values-xx (other languages) folder, where xx represents the corresponding language code.
3. Android loads the corresponding string resource file based on the language and region settings of the current device, and then displays the corresponding string content based on the respective key value. If there is no corresponding string resource file for the current device’s language and region settings, Android will use the default string resource file for display.
4. The process of generating the build.prop file:
5. Build.prop is a configuration file for the Android system, containing settings for various system properties. This file is typically located in the /system directory and is a text file. The process of generating the build.prop file is as follows:

   When the Android system initializes, it reads the /system/build.prop file and loads the property values into the system’s properties.
   The build.prop file can be modified by device manufacturers or ROM developers to adjust some system properties.
   While some property values can be modified using adb commands or other tools, in most cases, root permission is required to modify the build.prop file.

In conclusion, the way Android devices display strings is based on language and region settings to select the appropriate string resource file for display, and the build.prop file is a configuration file of the Android system containing settings for some system properties that can be modified and loaded into the system by device manufacturers or ROM developers.
