判断应用是安装还是卸载了

<receiver android:name="com.haolianluo.net.session.module.HAPKInstallReceiver">
   <intent-filter>
   <category android:name="android.intent.category.DEFAULT" /> 
  <action android:name="android.intent.action.PACKAGE_ADDED"></action>
   <data android:scheme="package"/>
   </intent-filter>
  
  <intent-filter>
   <category android:name="android.intent.category.DEFAULT" /> 
  <action android:name="android.intent.action.PACKAGE_REMOVED"></action>
   <data android:scheme="package"/>
   </intent-filter>
</receiver>
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

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", 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();
            }*/
           
        }
      
}
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
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="zy.Broadcast"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".Broadcast"
                  android:label="@string/app_name">

                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
      <receiver android:name="getBroadcast" android:enabled="true" >
         <intent-filter>
         <action android:name="android.intent.action.PACKAGE_ADDED"></action>

           <data android:scheme="package"></data>
              </intent-filter>
</receiver>
    </application>
    <uses-sdk android:minSdkVersion="7" />
   
</manifest>
