用gradlew编译打包的app，如何添加进Android源码做build

对于用android studio编辑完的app源码如何添加到系统的source去做编译呢？如果要求作为launcher启动呢？

没错就是写一个牛逼一点的Android.mk即可，上码子：

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := XXX

LOCAL_OVERRIDES_PACKAGES := Launcher3

LOCAL_SRC_FILES := $(LOCAL_MODULE).apk

LOCAL_MODULE_CLASS := APPS

LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)

LOCAL_CERTIFICATE := platform

LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/operator/app

PRIVATE_LOCAL_PATH := $(LOCAL_PATH)

PRIVATE_LOCAL_MODULE := $(LOCAL_MODULE)

$(LOCAL_PATH)/$(LOCAL_MODULE).apk: .git/modules/vendor/vinci/packages/apps/XXX/src/HEAD

find $(PRIVATE_LOCAL_PATH)/src -name *.apk -exec rm {} \;

echo "org.gradle.java.home=/usr/lib/jvm/java-7-openjdk-amd64" > $(PRIVATE_LOCAL_PATH)/src/gradle.properties

echo "sdk.dir=/workspace/share/android-sdk-linux" > $(PRIVATE_LOCAL_PATH)/src/local.properties

path=`pwd`; cd $(PRIVATE_LOCAL_PATH)/src; ./gradlew build; cd $$path

echo $(PRIVATE_LOCAL_PATH)/src/gradle.properties

rm $(PRIVATE_LOCAL_PATH)/src/gradle.properties

rm $(PRIVATE_LOCAL_PATH)/src/local.properties

cp $(PRIVATE_LOCAL_PATH)/src/app/build/outputs/apk/app-debug.apk $(PRIVATE_LOCAL_PATH)/$(PRIVATE_LOCAL_MODULE).apk

include $(BUILD_PREBUILT)

用此makefile编译出来之后，该app是以Launcher的位置出现在系统中的。
