如何在线制作印章湘潭seo快速排名

环境

系统：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。
