Android监听程序的安装和卸载

在android系统中，安装和卸载都会发送广播，当应用安装完成后系统会发android.intent.action.PACKAGE_ADDED广播。可以通过intent.getDataString()获得所安装的包名。当卸载程序时系统发android.intent.action.PACKAGE_REMOVED广播。同样intent.getDataString()获得所卸载的包名。应用程序无法监听自己的安装与卸载，但覆盖安装可以监听到自己的android.intent.action.PACKAGE_REMOVED广播。public class PackageReceiver extends BroadcastReceiver{@Override public void onReceive(Context context, Intent intent) { if (intent.getAction().equals("android.intent.action.PACKAGE_ADDED")) { String packageName = intent.getDataString(); Log.i("Test","---------------" + packageName); } if (intent.getAction().equals("android.intent.action.PACKAGE_REMOVED")) { String packageName = intent.getDataString(); Log.i("Test","---------------" + "PACKAGE_REMOVED" + packageName); }}}复制代码<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.test" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="测试"> <receiver android:name=".PackageReceiver" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.PACKAGE_ADDED" /> <action android:name="android.intent.action.PACKAGE_REMOVED" /> <data android:scheme="package" /> </intent-filter> </receiver> </application> <uses-sdk android:minSdkVersion="7" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.RESTART_PACKAGES"/> <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/></manifest>这里是手动注册广播
