开始启动一个Android的通知 [英] Starting an Android notification at startup
问题描述
此问题不基于我的这个previous问题: Android的 - 设置通知永远不会消失
This question is based off of this previous question of mine: Android - Set notification to never go away
我现在意识到我需要的东西在启动时被触发,触发通知。
I now realize that I need something to be triggered at startup to trigger the notification.
从我的previous问题,它看起来像我可以采取两种途径。无论是启动一个服务,或者使用一个BroadcastReceiver。我认为,启动的服务是有点矫枉过正(但我知道什么)。同时与广播接收器的路线去我被困。它的工作原理一般,但是当我把我的code的通知我收到了一堆错误。
From my previous question, it looks like I can take two routes. Either start a service, or use a BroadcastReceiver. I think that starting a service is a little overkill (but what do I know). I am stuck while going with the BroadcastReceiver route. It works in general, but when I take my code for a notification I get a bunch of errors.
这是我的code:
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("My notification")
.setContentText("Hello World!");
// Creates an explicit intent for an Activity in your app
Intent resultIntent = new Intent(this, ResultActivity.class);
//Intent.putExtra("My Notification");
// The stack builder object will contain an artificial back stack for the
// started Activity.
// This ensures that navigating backward from the Activity leads out of
// your application to the Home screen.
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
// Adds the back stack for the Intent (but not the Intent itself)
stackBuilder.addParentStack(ResultActivity.class);
// Adds the Intent that starts the Activity to the top of the stack
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent =
stackBuilder.getPendingIntent(
0,
PendingIntent.FLAG_UPDATE_CURRENT
);
mBuilder.setContentIntent(resultPendingIntent);
NotificationManager mNotificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// mId allows you to update the notification later on.
mNotificationManager.notify(i, mBuilder.build());
我的错误:
My errors:
在这个任何想法?
摘要:
是一个服务或广播接收器(在这种情况下)更好?
如何在我的code解决这些错误(当你徘徊,他们说,他们是不确定的)?
Summary: Is a service or broadcast receiver better (in this situation)? How do I solve these errors in my code (when you hover they say they are undefined)?
推荐答案
替换的所有实例这种
与情况下错误行
。
BroadcastReciever没有实现不同的活动和服务环境。在其中有错误的所有方法都需要上下文的实例
BroadcastReciever does not implement a context unlike Activity and Service. All methods in which you have error require an instance of context
