Android 监听程序的安装和卸载

有些时候,需要监听到程序是否安装或者卸载成功,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。

    所以,只需要自定义一个BroadcastReceiver,来对系统广播进行监听和处理。

    1、自定义广播
          自定义广播MyInstalledReceiver继承自BroadcastReceiver,实现其onReceive()方式,具体代码如下:


[html]
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){ 
        //接收安装广播  
        if (intent.getAction().equals("android.intent.action.PACKAGE_ADDED")) {    
            String packageName = intent.getDataString();    
            System.out.println("安装了:" +packageName + "包名的程序");      
        }    
        //接收卸载广播   
        if (intent.getAction().equals("android.intent.action.PACKAGE_REMOVED")) {    
            String packageName = intent.getDataString();    
            System.out.println("卸载了:"  + packageName + "包名的程序"); 
  
        } 
    } 

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){
        //接收安装广播
        if (intent.getAction().equals("android.intent.action.PACKAGE_ADDED")) {  
            String packageName = intent.getDataString();  
            System.out.println("安装了:" +packageName + "包名的程序");    
        }  
        //接收卸载广播 
        if (intent.getAction().equals("android.intent.action.PACKAGE_REMOVED")) {  
            String packageName = intent.getDataString();  
            System.out.println("卸载了:"  + packageName + "包名的程序");
 
        }
    }
}      2、注册监听

            1) xml 方式:在AndroidManifest.xml 配置文件的Application节点下,添加自定义的注册监听 MyInstalledReceiver,在AndroidManifest.xml 添加的注册监听,其生命周期默认是整个应用的生命周期。          


[html]
<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.example.apk" 
    android:versionCode="1" 
    android:versionName="1.0" > 
 
    <application 
        android:icon="@drawable/ic_launcher" 
        android:label="@string/app_name" > 
        <activity 
            android:name=".MainActivity" 
            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=".MyInstalledReceiver" > 
            <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="3" /> 
</manifest> 

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.apk"
    android:versionCode="1"
    android:versionName="1.0" >

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
