android自动点击的实现流程记录

一个android下自动点击触屏的程序，类似于windows下的按键精灵，自动帮我玩捕鱼达人

目标：用户可以通过配置脚本文件，自定义一系列的操作，例如：点击/长按/拖动/延时/颜色判断/循环，然后用音量+/-键启动/关闭脚本

思路：

1.linux下做一个c程序gameplug.c，此程序负责读取配置文件，完成用户定义的一系列操作。

2.init.rc中添加服务，该服务启动gameplug.c

3.framework用音量+/-开启/关闭服务。

4.settings中增加gameplug的选项，打开后音量+/-键用作启动/关闭脚本服务，关闭后做正常音量+/-用



流程：

1.写好自己的linux服务程序

android\system\core\toolbox\gameplug.c

修改android\system\core\toolbox\Android.mk，增加gameplug.c的编译选项



2.制作libgameplug.so供上层调用
新建android\system\core\libgameplug\文件夹，增加gameplug.c和Android.mk，gameplug.c负责启动
android\system\core\include\gameplug\gameplug.h，和JNI的接口
自己添加的自定义so文件库在编译的时候出现以下错误
-----------------------------------------------------------------------------
build/core/base_rules.mk:78: *** Module name: libgameplug

-----------------------------------------------------------------------------
需要在android\build\core\user_tags.mk中添加你在Android.mk中LOCAL_MODULE定义的名字
这里是LOCAL_MODULE := libgameplug

3.init.rc增加service gameplug
android\system\core\rootdir\init.rc
service gameplug /system/bin/gameplug
disabled
oneshot



4.注册framework层JNI接口函数

添加 android\frameworks\base\services\jni\com_android_server_GameplugService.cpp

修改 android\frameworks\base\services\jni\onload.cpp

修改 android\frameworks\base\services\jni\Android.mk

修改 android\frameworks\base\services\java\com\android\server\SystemServer.java

修改 android\frameworks\base\services\java\com\android\server\GameplugService.java

增加 android\frameworks\base\core\java\android\os\IGameplugService.aidl

修改 android\frameworks\base\Android.mk

5.控制,volume+ start , volume- stop
修改 android\frameworks\base\media\java\android\media\AudioManager.java

6.package/app/settings增加选项enable/disbale gameplug，打开此选项后音量+/-当启动/关闭gameplug用，关闭此项还做音量键使用

修改 android\packages\apps\Settings\res\values\strings.xml

修改 android\packages\apps\Settings\res\xml\display_settings.xml

修改 android\packages\apps\Settings\src\com\android\settings\DisplaySettings.java

修改 android\frameworks\base\core\java\android\provider\Settings.java



7.编译

make update-api
make android
