The boot animation of Android 12 is achieved using system properties and the init process. Below is a detailed explanation of the code and process of Android 12 boot animation.<\/p>\n

    \n
  1. The configuration file for the system, located at \/system\/build.prop.<\/li>\n<\/ol>\n
    # \u5f00\u673a\u52a8\u753b\u63a7\u5236\u5c5e\u6027\r\npersist.sys.bootanimation.enable=1\r\npersist.sys.bootanimation.name=bootanimation.zip\r\n<\/code><\/pre>\n
      \n
    1. The persist.sys.bootanimation.enable property is used to enable or disable the boot animation. Setting it to 1 enables the animation, while setting it to 0 disables it.<\/li>\n
    2. The persist.sys.bootanimation.name property specifies the name of the boot animation file.<\/li>\n<\/ol>\n
        \n
      1. init.rc is the initial script file for the Android operating system.<\/li>\n<\/ol>\n
        on property:persist.sys.bootanimation.enable=1\r\n    start bootanim\r\n<\/code><\/pre>\n
        When the value of the persist.sys.bootanimation.enable property is set to 1, the init process will start a service named bootanim.<\/p>\n
          \n
        1. start-up configuration file<\/li>\n<\/ol>\n
          service bootanim \/system\/bin\/bootanimation\r\n    class core\r\n    user graphics\r\n    group graphics\r\n    disabled\r\n    oneshot\r\n<\/code><\/pre>\n
          This code segment defines a service named bootanim, which starts the boot animation using the \/system\/bin\/bootanimation executable file.<\/p>\n
            \n
          1. The implementation of the boot animation: The boot animation file bootanimation.zip is a compressed file that contains a series of image files and description files. The main logic of the boot animation implementation is in the \/system\/bin\/bootanimation file.<\/li>\n
          2. Analyze the boot animation file: the \/system\/bin\/bootanimation file will read the bootanimation.zip file, parse the description file desc.txt within it, and extract information such as the frame rate and interval of the boot animation.<\/li>\n
          3. Playing the boot animation: The \/system\/bin\/bootanimation file will sequentially display the image files in bootanimation.zip according to the frame rate and frame interval to achieve the animation effect.<\/li>\n<\/ol>\n
            The above provides a detailed explanation of the code and process of the Android 12 boot animation. Developers can customize the implementation logic and effects of the boot animation according to their own needs.<\/p>\n","protected":false},"excerpt":{"rendered":"
