Android(安卓)监控程序安装和删除的实现

通过阅读Android SDK里关于intent.action这部分里面的描述，我们可以找到一些与package相关的系统广播

     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

其中

ACTION_PACKAGE_ADDED

在SDK里的描述是

Broadcast Action: A new application package has been installed on the device.

ACTION_PACKAGE_REMOVED

在SDK里的描述是

Broadcast Action: An existing application package has been removed from the device.

ACTION_PACKAGE_REPLACED

在SDK里的描述是

Broadcast Action: A new version of an application package has been installed, replacing an existing version that was previously installed.

通过这三个广播消息我们已经可以监控到Android 应用程序的安装和删除

详细的实现代码如下:

     packagezy.Broadcast;
   importandroid.content.BroadcastReceiver;
   importandroid.content.Context;
   importandroid.content.Intent;
   importandroid.widget.Toast;
   publicclassgetBroadcastextendsBroadcastReceiver{
   @Override
   publicvoidonReceive(Contextcontext,Intentintent){
   
   if(Intent.ACTION_PACKAGE_ADDED.equals(intent.getAction())){
   Toast.makeText(context,"有应用被添加",Toast.LENGTH_LONG).show();
   }
   elseif(Intent.ACTION_PACKAGE_REMOVED.equals(intent.getAction())){
   Toast.makeText(context,"有应用被删除",Toast.LENGTH_LONG).show();
   }
   /*elseif(Intent.ACTION_PACKAGE_CHANGED.equals(intent.getAction())){
   Toast.makeText(context,"有应用被改变",Toast.LENGTH_LONG).show();
   }*/
   elseif(Intent.ACTION_PACKAGE_REPLACED.equals(intent.getAction())){
   Toast.makeText(context,"有应用被替换",Toast.LENGTH_LONG).show();
   }
   /*elseif(Intent.ACTION_PACKAGE_RESTARTED.equals(intent.getAction())){
   Toast.makeText(context,"有应用被重启",Toast.LENGTH_LONG).show();
   }*/
   /*elseif(Intent.ACTION_PACKAGE_INSTALL.equals(intent.getAction())){
   Toast.makeText(context,"有应用被安装",Toast.LENGTH_LONG).show();
   }*/
   
   }
   
   }

然后在AndroidManifest.xml中声明这几个Action的<intent-filter>即可在系统里捕获这些广播消息

具体的源代码如下

     <receiverandroid:name="getBroadcast"android:enabled="true">
   <intent-filter>
   <actionandroid:name="android.intent.action.PACKAGE_ADDED"></action>
   <!--<actionandroid:name="android.intent.action.PACKAGE_CHANGED"></action>-->
   <actionandroid:name="android.intent.action.PACKAGE_REMOVED"></action>
   <actionandroid:name="android.intent.action.PACKAGE_REPLACED"></action>
   <!--<actionandroid:name="android.intent.action.PACKAGE_RESTARTED"></action>-->
   <!--<actionandroid:name="android.intent.action.PACKAGE_INSTALL"></action>-->
   <dataandroid:scheme="package"></data>
   </intent-filter>
   </receiver>

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

package:com.android.myapp
