Android系统之路(初识MTK) ------ 内置三方apk到Rom可移动/可卸载

客户给了一个内置他们自己apk的需求，定制到Rom里，我们需要在编译系统源码的时候配置好相关的文件即可将apk一起打包到ROM里面，下面我们就来一起打包apk到系统

首先需要在 device/mediatek/common/device.mk 配置如下语句

$(call inherit-product-if-exists, vendor/公司名/product/您的命名.mk)

在mk文件里面配置需要内置的apk label

eg:

#apps
PRODUCT_PACKAGES += \
			BDDataPlan\
			Facebook\
			MultiLingBengaliPlugin\
			Multilingkeyboard\
			SHAREit\
			Skype\
			Viber\
			WPSOffice\
			WST_WAL_C

配置好之后还需要导入 apk文件并且配置宏，就写一个例子吧，也在这个文件夹下写

路径：vendor\公司名\ThirdpartyApps\

配置如下mk文件，没有的自己创建

LOCAL_PATH := $(call my-dir)
#
include $(CLEAR_VARS)
LOCAL_MODULE := BDDataPlan
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/operator/app
#LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/thirdparty_apps
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE := PRESIGNED
include $(BUILD_PREBUILT)

#
include $(CLEAR_VARS)
LOCAL_MODULE := Facebook
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/operator/app
#LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/thirdparty_apps
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE := PRESIGNED
include $(BUILD_PREBUILT)

#
include $(CLEAR_VARS)
LOCAL_MODULE := MultiLingBengaliPlugin
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/operator/app
#LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/thirdparty_apps
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE := PRESIGNED
include $(BUILD_PREBUILT)

#
include $(CLEAR_VARS)
LOCAL_MODULE := Multilingkeyboard
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE_CLASS := APPS
#LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/operator/app
LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/thirdparty_apps
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE := PRESIGNED
include $(BUILD_PREBUILT)

#
include $(CLEAR_VARS)
LOCAL_MODULE := SHAREit
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/operator/app
#LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/thirdparty_apps
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE := PRESIGNED
include $(BUILD_PREBUILT)

#
include $(CLEAR_VARS)
LOCAL_MODULE := Skype
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/operator/app
#LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/thirdparty_apps
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE := PRESIGNED
include $(BUILD_PREBUILT)

#
include $(CLEAR_VARS)
LOCAL_MODULE := Viber
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/operator/app
#LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/thirdparty_apps
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE := PRESIGNED
include $(BUILD_PREBUILT)

#
include $(CLEAR_VARS)
LOCAL_MODULE := WPSOffice
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/operator/app
#LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/thirdparty_apps
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE := PRESIGNED
include $(BUILD_PREBUILT)

#
include $(CLEAR_VARS)
LOCAL_MODULE := WST_WAL_C
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/operator/app
#LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/thirdparty_apps
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE := PRESIGNED
include $(BUILD_PREBUILT)

工作算是完成了一半，接下来还需要修改frameworks下的java文件，让内置的三分apk可卸载等操作

/frameworks/base/services/core/java/com/android/server/pm/PackageManagerService.java

添加：

+            final File thirdpartyAppDir = new File(Environment.getRootDirectory(), "/vendor/thirdparty_apps");

+            scanDirLI(thirdpartyAppDir, PackageParser.PARSE_IS_SYSTEM

+                    | PackageParser.PARSE_IS_SYSTEM_DIR, scanFlags, 0);

添加：

+    private static boolean isThirdpartyApp(int parseFlags) {

+               return (parseFlags & PackageParser.PARSE_IS_THIRDPARTY_APP) != 0;

+       }

public static int PackageParser.PARSE_IS_THIRDPARTY_APP = 1<<11;

修改：

+        if (isSystemApp(pkg) && !isUpdatedSystemApp(pkg) && !isThirdpartyApp(parseFlags)) {

不知道在那行的，可以搜索关键字，ctrl+L 索引行

修改完之后编译工程，发现以下异常：

 No rule to make target `vendor/rmt/ThirdpartyApps/WST_WAL_C.apk', needed by `out/target/product/rmt8382_tb_l/obj/APPS/WST_WAL_C_intermediates/package.apk'.  Stop

检查了下配置文件，发现客户提供的apk文件跟我们的mk冲突了，于是修改

WST_WAL_C.APK 为 WST_WAL_C.apk

重新编译工程，完美运行

最终效果，内置9个apk，7个可见，2个后台
