重启后android通知 [英] android notification after reboot

问题描述

我想在通知栏中放置一个通知，按下时将启动我的应用程序.虽然我这样做没有问题，但我的用户也希望在重新启动后出现通知.他们有来自其他供应商的应用程序可以执行此操作.

I want to put up a notification in the notification bar that will launch my app when pressed. While I have no problems doing this, my users want the notification to come up after a reboot as well. They have an app from another vendor that does this.

我能找到的一切都表明应用程序必须正在运行才能显示通知.有什么想法吗?

Everything I can find states that the app must be running for the notification to display. Any ideas?

推荐答案

您需要添加一个在重启后启动服务的接收器.

You need to add a receiver that launches a Service after a reboot.

在您的清单中注册 Boot Complete

In your manifest register for Boot Complete

<service android:name="com.meCorp.service.MeCorpServiceClass"/>
...
<receiver android:name="com.meCorp.receiver.MyRebootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
...
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>

在您的启动接收器中，启动一项服务.

In your boot receiver, launch a service.

public class MyRebootReceiver extends BroadcastReceiver {

       @Override
       public void onReceive(Context context, Intent intent) {
          Intent serviceIntent = new Intent(context, MeCorpServiceClass.class);
          serviceIntent.putExtra("caller", "RebootReceiver");
          context.startService(serviceIntent);
       }
}

这是一个在后台运行的服务类的示例.

Here is an example for a service class to run in the background.

    public class MeCorpServiceClass extends IntentService{

         @Override
         protected void onHandleIntent(Intent intent){
             String intentType = intent.getExtras().getString("caller");
             if(intentType == null) return;
             if(intentType.Equals("RebootReceiver"))
                  //Do reboot stuff
             //handle other types of callers, like a notification.
         }
     }
