最近看到应用宝最新版也加了新功能“省心装”，觉得这玩意挺不错，就研究了下，奈何网上资料少的渣渣，便参考了如下几篇文章自己动手简单实现了下。

添加权限

<uses-permission android:name="android.permission.BIND_ACCESSIBILITY_SERVICE"/>

在清单文件里注册service

<!--省心装--><service android:name=".module.accessibility_service.MAcessibilityService"android:label="@string/acc_auto_install_service_name"android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE"android:enabled="@bool/atLeastIceCreamSandwich"><intent-filter><action android:name="android.accessibilityservice.AccessibilityService" /></intent-filter><meta-data
                android:name="android.accessibilityservice"android:resource="@xml/accessibility_config" /></service>

atLeastIceCreamSandwich”是判定当前系统是否api-14及以上版本，14以下的便自己手动安装吧>~<：
accessibility_config是配置文件,在res的xml文件夹下：

配置文件

<?xml version="1.0" encoding="utf-8"?>
<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"android:description="@string/acc_auto_install_service_description"android:accessibilityEventTypes="typeAllMask"android:accessibilityFlags="flagDefault"android:accessibilityFeedbackType="feedbackGeneric"android:notificationTimeout="100"android:canRetrieveWindowContent="true"android:packageNames="com.android.packageinstaller"
/>

description：是描述，在辅助功能里展示。
packageNames：就是要监听的包名，可以有多个，中间用逗号隔开。比如 “packageName1, packageName2”。

}

自定义服务中的字符串

values/strings

 <!-- 省心装--><string name="install">INSTALL</string><string name="installing">Installing…</string><string name="done">DONE</string><string name="next">NEXT</string>

values-zh-rCN/strings

 <!-- 省心装--><string name="install">安装</string><string name="installing">正在安装...</string><string name="done">完成</string><string name="next">下一步</string>

总结

如上，很简单就实现了自动安装的功能，当然这里没有对所有机型进行适配。在使用的时候要注意一点是，在使用的时候添加如下一行代码,这样服务才会进行检查：

MAcessibilityService.setEnable(true);
