Android 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:

package zy.Broadcast;   
import android.content.BroadcastReceiver;   
import android.content.Context;   
import android.content.Intent;   
import android.widget.Toast;   
public class getBroadcast extends BroadcastReceiver {   
        @Override   
        public void onReceive(Context context, Intent intent) {   
                  
                  if(Intent.ACTION_PACKAGE_ADDED.equals(intent.getAction())){   
                    Toast.makeText(context, "有应用被添加", Toast.LENGTH_LONG).show();   
            }   
                else  if(Intent.ACTION_PACKAGE_REMOVED.equals(intent.getAction())){   
                    Toast.makeText(context, "有应用被删除", To
