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. } }

或者只需使用 Urban AirShip 等第三方，它会为您处理所有这些.
