第1、 新建監聽類:BootReceiver繼承BroadcastReceiver android
package com.rongfzh.yc; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; public class BootReceiver extends BroadcastReceiver{ @Override public void onReceive(Context context, Intent intent){ //接收安裝廣播 if (intent.getAction().equals("android.intent.action.PACKAGE_ADDED")) { String packageName = intent.getDataString(); System.out.println("安裝了:" +packageName + "包名的程序"); } //接收卸載廣播 if (intent.getAction().equals("android.intent.action.PACKAGE_REMOVED")) { String packageName = intent.getDataString(); System.out.println("卸載了:" + packageName + "包名的程序"); } } }
第2、 修改AndroidManifest.xml配置文件,添加廣播介紹,添加監聽的權限api
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.rongfzh.yc" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="7" /> <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" > <activity android:name=".PakDetectActivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <receiver android:name=".BootReceiver" 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-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.RESTART_PACKAGES"/> <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/> </manifest>
三、運行程序,卸載一個程序ApiDemos程序打印日誌以下app
System.out(1513): 卸載了:package:com.example.android.apis包名的程序ide
四、安裝騰訊微博,打印日誌以下:.net
System.out(1513): 安裝了:package:com.tencent.WBlog包名的程序日誌
程序監聽成功。xml
