Rockchip平台Android应用预安装功能(基于Android13)
1. 预安装应用类型
Android上的应用预安装功能主要是指配置产品时根据厂商要求将事先准备好的第三方应用预置进Android系统。预安装分为以下几种类型
安装不可卸载应用安装可永久卸载应用安装卸载后恢复出厂设置后自动恢复的应用
2. 功能启用说明
2.1 配置和使用
在进行以下操作之前首先需要输入命令 get_build_var TARGET_DEVICE_DIR 来找到对应的目标文件夹比如 device/rockchip/rk3126c/。
在目标文件夹下有三个文件夹分别为
preinstallpreinstall_del_foreverpreinstall_del
请将需要预置的应用放入对应的文件夹注意apk文件名尽量使用英文避免空格。
顺利的话执行make之后会在$OUT/oem目录生成对应的文件夹
bundled_persist-appbundled_uninstall_gone-appbundled_uninstall_back-app
仍旧对应概述中的几种类型。在烧录后系统会自动安装这些应用到对应目录。
注意不支持带systemuid应用的预制请使用Android原生方式编写mk文件。可参考vendor/rockchip/common/apps/RkDeviceTest/的集成方式。
2.2 编译结果
编译后配置文件将会输出到odm分区$OUT/oem/增加后请确认烧写了odm.img来使其生效。
3. 预编译脚本
预置应用编译脚本通过下面脚本完成
ifneq ($(strip $(TARGET_PRODUCT)), )$(shell python device/rockchip/common/auto_generator.py $(TARGET_DEVICE_DIR) preinstall bundled_persist-app $(TARGET_ARCH))$(shell python device/rockchip/common/auto_generator.py $(TARGET_DEVICE_DIR) preinstall_del bundled_uninstall_back-app $(TARGET_ARCH))$(shell python device/rockchip/common/auto_generator.py $(TARGET_DEVICE_DIR) preinstall_del_forever bundled_uninstall_gone-app $(TARGET_ARCH))-include $(TARGET_DEVICE_DIR)/preinstall/preinstall.mk-include $(TARGET_DEVICE_DIR)/preinstall_del/preinstall.mk-include $(TARGET_DEVICE_DIR)/preinstall_del_forever/preinstall.mk
endif可以看到预置应用的Android.mk主要通过auto_generator.py完成
