Android 监控程序安装和删除的实现

android.intent.action.PACKAGE_ADDED       
android.intent.action.PACKAGE_CHANGED       
android.intent.action.PACKAGE_DATA_CLEARED       
android.intent.action.PACKAGE_INSTALL     
android.intent.action.PACKAGE_REMOVED     
android.intent.action.PACKAGE_REPLACED       
android.intent.action.PACKAGE_RESTARTED 

两种方法：

1、代码

1, Define a class extends BroadcastReceiver;
2, Register broadcast receiver;
UninstallApp receiver = new UninstallApp();
IntentFilter filter = new IntentFilter(Intent.ACTION_PACKAGE_INSTALL);
filter.addAction(Intent.ACTION_PACKAGE_REMOVED);
filter.addDataScheme("package"); //This line is very important. Otherwise, broadcast can't be received.这一行很得要
registerReceiver(receiver, filter);

2、XML

<data android:scheme="package"></data> This line is very important. Otherwise, broadcast can't be received. 这一行很重要

<PRE class=javascript name="code"><receiver android:name="getBroadcast" android:enabled="true" >   
         <intent-filter>   
             <action android:name="android.intent.action.PACKAGE_ADDED"></action>   
             <!-- <action android:name="android.intent.action.PACKAGE_CHANGED"></action>-->   
             <action android:name="android.intent.action.PACKAGE_REMOVED"></action>   
             <action android:name="android.intent.action.PACKAGE_REPLACED"></action>   
             <!-- <action android:name="android.intent.action.PACKAGE_RESTARTED"></action>-->   
           <!--    <action android:name="android.intent.action.PACKAGE_INSTALL"></action>-->   
               <data android:scheme="package"></data>   
         </intent-filter>   
</receiver></PRE>

另： intent.getDataString()可以得到安装的是哪个apk，如：<P></P>
