带有源码的apk预置到系统

带有源码的apk预置到系统

如何将android stuido 下的android代码内置到 android源码中去呢？

在package/apps/下需要预置的APK的名字创建爱你一个新文件夹。 例如创建的应用名称是TopActivity

将在android studio下的TopActivity的\app\src\main目录下的 java res AndroidMainfest.xml文件拷贝到 创建的目录下

在TopActivity下创建 android 下创建Android.mk 文件

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE_TAGS:=optional
LOCAL_STATIC_JAVA_LIBRARIES:=android-support-v4
LOCAL_SRC_FILES := \
$(call all-java-files-under, java)
LOCAL_RESOURCE_DIR := $(LOCAL_PATH)/res
LOCAL_PACKAGE_NAME := TopActivity
LOCAL_CERTIFICATE := platform
LOCAL_PRIVILEGED_MODULE := true
include $(BUILD_PACKAGE)

TopActivity 应用需要android-support-v4的jar包，因此需要使用LOCAL_STATIC_JAVA_LIBRARIES 指定一些

LOCAL_CERTIFICATE := platform 是系统的平台签名

LOCAL_PRIVILEGED_MODULE := true 表示应用需要系统的权限

在package/apps/TopActivity/下 mmm .

在android源码的目录下 make snod 打包

带有jni文件的app

需要在 java res 下建立jni的文件目录

在目录下新建Android.mk

LOCAL_PATH:$(call my-dir)
#include $(CLEAR_VARS)
LOCAL_SHARED_LIBRARIES :=liblog libc
LOCAL_PRELINK_MODULE:=false
LOCAL_C_INCLUDES:=$(JNI_H_INCLUDE)
LOCAL_SRC_FILES: = \
hardcontrol.cpp
LOCAL_MODULE:=libhardcontrol
include $(BUILD_SHARED_LIBRARY)

在源码的目录下新建的Android.mk

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE_TAGS:=optional
LOCAL_SRC_FILES := \
$(call all-java-files-under, java)
LOCAL_RESOURCE_DIR := $(LOCAL_PATH)/res
LOCAL_PACKAGE_NAME := LEDdemo
LOCAL_CERTIFICATE := platform
LOCAL_PRIVILEGED_MODULE := true
LOCAL_JNI_SHARED_LIBRARIES :=libhardcontrol
LOCAL_REQUIRED-MODULED:= libhardcontrol
include $(BUILD_PACKAGE)

此时需要指出JNI动态库

编译记录

Install: out/target/product/tiny4412/system/priv-app/LEDdemo/LEDdemo.apk
mkdir -p out/target/product/tiny4412/system/priv-app/LEDdemo/lib/arm  ;ln -sf /system/lib/libhardcontrol.so out/target/product/tiny4412/system/priv-app/LEDdemo/lib/arm/libhardcontrol.so

无源码的apk内置android系统

内置讯飞输入法

将官网下载的讯飞输入法的apk明明为 FlyIME.apk

在package/apps/下创建FlyIME文件夹，在创建apps

目录：/packages/apps/FlyIME/apps

├── Android.mk

└── FlyIME.apk

创建的Android.mk的内容为

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
# Module name should match apk name to be installed
LOCAL_MODULE := FlyIME
LOCAL_MODULE_TAGS := optional
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX) LOCAL_PREBUILT_JNI_LIBS:=                   \
@lib/armeabi/libcom_iflytek_inputmethod_mmp.so \
@lib/armeabi/libdexopt.so  \
@lib/armeabi/libmsc-v8.so  \
@lib/armeabi/libNativeCrashCollect.so \
@lib/armeabi/libsmartaiwrite-jni-v22.so \
@lib/armeabi/libvadLib-v5.so \
@lib/armeabi/libwatchdog.so
LOCAL_CERTIFICATE := PRESIGNED
LOCAL_PRIVILEGED_MODULE := true
include $(BUILD_PREBUILT)

需要注意的是，如果这个apk带有so文件。需要将lib/arm下的so文件按照LOCAL_PREBUILT_JNI_LIBS:= \

@lib/armeabi/libcom_iflytek_inputmethod_mmp.so

这样的格式来写。
