Android应用程序升级后自动进入新版本

在新版本中创建一个Receiver接收手机应用的安装和卸载（可以监听到旧版本的卸载）

package
com.justsy.lpi.receiver;

import
android.content.BroadcastReceiver;
import
android.content.Context;
import
android.content.Intent;

public
class PkInstallReceiver extends BroadcastReceiver {

     
@Override
     
public void onReceive(Context context, Intent intent) {

           
if (intent.getAction().equals("android.intent.action.PACKAGE_ADDED" )) {  
            String packageName = intent.getDataString().substring(8);
            System.
out.println( "安装:" +packageName + "包名的程序" );
        }  
       
//接收卸载广播 
       
if (intent.getAction().equals("android.intent.action.PACKAGE_REMOVED" )) {  
            String packageName = intent.getDataString().substring(8);  
            System.
out.println( "卸载:"  + packageName + "包名的程序" );
            Intent newIntent =
new Intent();
            newIntent.setClassName(packageName,packageName+
".AutoStartProTestActivity" );   
            newIntent.setAction(
"android.intent.action.MAIN");               
            newIntent.addCategory(
"android.intent.category.LAUNCHER" );               
            newIntent.setFlags(Intent.
FLAG_ACTIVITY_NEW_TASK);      
            context.startActivity(newIntent);
        }
     }

}

AndroidManifest.xml进行配置

         <receiver android:name="com.justsy.lpi.receiver.PkInstallReceiver"  
                  android:label=" @string/app_name">   
            <intent-filter>  
             <action android:name="android.intent.action.PACKAGE_ADDED" /> 
             <action android:name="android.intent.action.PACKAGE_REMOVED" /> 
              <data android:scheme="package" /> 
            </intent-filter>  
        </receiver>

      <uses-permission android:name= "android.permission.RESTART_PACKAGES" /> 
    <uses-permission android:name= "android.permission.RECEIVE_BOOT_COMPLETED" />
