系统#xff1a;Android 8 CPU:MTK 理论上改法适用于其他平台#xff0c;比如展讯。 不适用于安卓11。安卓11请参照android 11预装APP到data/app目录
实现
假设要内置test这个应用。 第一步把test添加到系统编译配置中#xff0c;不同平台或cpu文件不一样。 比如Android 8 CPU:MTK 理论上改法适用于其他平台比如展讯。 不适用于安卓11。安卓11请参照android 11®预装APP到data/app目录
实现
假设要内置test这个应用。 第一步把test添加到系统编译配置中不同平台或cpu文件不一样。 比如 device/mediateksample/xx/device.mk PRODUCT_PACKAGES test 然后是创建Android.mk, 这一步很关键很多种写法都可能要问题。
错误写法1
Adroid.mk有问题的写法
LOCAL_PATH : $(call my-dir)
include $(CLEAR_VARS)LOCAL_MODULE : testapp
LOCAL_MODULE_TAGS : optional
LOCAL_SRC_FILES : $(LOCAL_MODULE).apk
LOCAL_MODULE_CLASS : APPS
LOCAL_MODULE_SUFFIX : $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE : PRESIGNED
LOCAL_PRIVILEGED_MODULE : true
LOCAL_MODULE_PATH : $(TARGET_OUT)/system/vendor/operator/app
include $(BUILD_PREBUILT)错误写法2
另外一种写法是针对Android新版本的在安卓8中不能这么写 LOCAL_MODULE_PATH : $(TARGET_OUT)/system/vendor 这种改法会出错 Non-symlink out/target/product/xx/system/vendor detected! You cannot install files to out/target/product/xx/system/vendor while building a separate vendor.img!
错误写法3
使用这个目录也有问题 $(TARGET_OUT)/system/vendor/operator/app 2023-11-01 08:02:24.012 635-635/system_process I/PackageManager: /vendor/operator/app/xx changed; collecting certs 2023-11-01 08:02:24.174 635-635/system_process W/PackageManager: Failed to scan /vendor/operator/app/test: Failed to collect certificates from /vendor/operator/app/test/test.apk
错误写法4
也不能放data/app/目录下 注意如果这么写可能会出错
LOCAL_PATH : $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE : test
LOCAL_MODULE_CLASS : APPS
LOCAL_MODULE_TAGS : optional
LOCAL_MODULE_SUFFIX : $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_MODULE_PATH : $(TARGET_OUT_DATA_APPS)
LOCAL_CERTIFICATE : PRESIGNED
LOCAL_PRIVILEGED_MODULE : true
LOCAL_DEX_PREOPT:false
LOCAL_SRC_FILES : $(LOCAL_MODULE).apk
include $(BUILD_PREBUILT)2023-11-01 08:01:01.132 634-634/system_process W/PackageManager: Failed to scan /data/app/test: Failed to collect certificates from /data/app/xx/text.apk
正确写法
Android.mk要按这样写
LOCAL_PATH : $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE : test
LOCAL_POST_PROCESS_COMMAND : $(shell mkdir -p $(TARGET_OUT_DATA_APPS)/$(LOCAL_MODULE)
LOCAL_POST_PROCESS_COMMAND : $(shell cp -r $(LOCAL_PATH)/$(LOCAL_MODULE).apk $(TARGET_OUT_DATA_APPS)/$(LOCAL_MODULE)/)修改PackageManagerService.java注释掉PackageManagerException(INSTALL_FAILED_INVALID_INSTALL_LOCATION 否则启动会报这个异常。
