Android(安卓)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><PRE></PRE><P><BR></P><P><PRE class=javascript name="code">import android.content.BroadcastReceiver;  import android.content.Context;  import android.content.Intent;  import android.util.Log;    public class UninstallApp extends BroadcastReceiver {        @Override      public void onReceive(Context context, Intent intent) {          Log.e("intent", "intent="+intent.getAction());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", Toast.LENGTH_LONG).show();               }                /*   else  if(Intent.ACTION_PACKAGE_CHANGED.equals(intent.getAction())){                      Toast.makeText(context, "有应用被改变", Toast.LENGTH_LONG).show();              }*/                   else  if(Intent.ACTION_PACKAGE_REPLACED.equals(intent.getAction())){                       Toast.makeText(context, "有应用被替换", Toast.LENGTH_LONG).show();               }                  /* else  if(Intent.ACTION_PACKAGE_RESTARTED.equals(intent.getAction())){                      Toast.makeText(context, "有应用被重启", Toast.LENGTH_LONG).show();              }*/                 /*  else  if(Intent.ACTION_PACKAGE_INSTALL.equals(intent.getAction())){                      Toast.makeText(context, "有应用被安装", Toast.LENGTH_LONG).show();              }*/     }    }  </PRE><BR>另： intent.getDataString()可以得到安装的是哪个apk，如：<P></P><SPAN style="FONT-WEIGHT: normal">  package:com.android.myapp</SPAN><BR><BR><P></P><BR>
