接收器停止在Oreo中接收 [英] Receiver stopped receiving in Oreo

问题描述

我了解服务，并且此类服务受到限制，因此我的接收器已停止在Android Oreo中工作。

I understand services and such are being clamped down on, so my receiver has stopped working in Android Oreo.

我有这段代码可以启动服务-

I have this code starting the service -

Intent intent = new Intent(this, MyService.class);
intent.putExtra("Time", locationUpdatesTime);
intent.putExtra("Dist", locationUpdatesDistance);
startService(intent);

我在我的服务中有此服务-

I have this in my service -

Intent intent = new Intent();
intent.setAction("com.androidandyuk.laptimerbuddy");
intent.addFlags(Intent.FLAG_INCLUDE_STOPPED_PACKAGES);
intent.putExtra("Lat", thisLat);
intent.putExtra("Lon", thisLon);

sendBroadcast(intent);

但是我的接收器从未被呼叫。搜索后，我认为我必须注册接收器，但是我无法确定如何使用正确的语法对此进行编码。有人可以帮忙吗？

But my receiver is never called. Having searched around I think I have to register my receiver, but I can't figure how I code this with the correct syntax. Can anyone help please?

如果您想对我投反对票，请多加说明一下，我们将不胜感激，因此我可以在寻找答案的同时学习，找不到/理解它，我想我已经按要求列出了问题：-）

If you wish to downvote me, I'd appreciate if you would comment why, so I can learn as I've looked for an answer, couldn't find/understand it and I think I've laid the question out as I should :-)

非常感谢！

更新。尝试使用LocalBroadcastManager。

UPDATE Trying to use a LocalBroadcastManager.

在MainActivity中，我有-

In MainActivity I have -

BroadcastReceiver mMessageReceiver;

onCreate我有-

onCreate I have -

mMessageReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            // Get extra data included in the Intent
            String message = intent.getStringExtra("message");
            Log.i("receiver", "Got message: " + message);
        }
    };
    LocalBroadcastManager.getInstance(this).registerReceiver(mMessageReceiver, new IntentFilter("custom-event-name"));

在我的服务中，onLocationChanged

In my service, onLocationChanged

    Log.i("sender", "Broadcasting message");
                Intent intent = new Intent();
                intent.setAction("custom-event-name");
                intent.putExtra("message", "This is my message!");

 LocalBroadcastManager.getInstance(getApplicationContext()).sendBroadcast(intent);

这在我看到发件人消息时起作用。

This works as I see the sender message.

我在做什么错？

推荐答案

自Android Oreo以来，必须在运行时使用context.registerReceiver（receiver注册接收者，intentFilter）;接收隐式意图

Since Android Oreo, receivers must be registered in runtime using context.registerReceiver(receiver, intentFilter); to receive implicit intents

您仍然可以接收显式意图和一些特殊的隐式动作，例如boot_completed或locale_changed

You can still receive explicit intents and some special implicit actions, as boot_completed or locale_changed for example
