从服务中删除持续通知
我有一项在启动时创建通知的服务。
然后 ondestroy() 我希望将其删除。
我只是使用 .cancel(NOTIFICATION_ID);
当它是正常通知时它效果很好，但当我使用正在进行的事件时它不会取消它。
我确实读到过一些关于如果 Android 有资源的话服务就不会停止的内容，但是如何克服这个问题呢？
我使用此代码来启动服务
final Intent bg_service = new Intent(BackgroundService.class.getName());
btn_start = (Button)findViewById(R.id.btn_start);
btn_stop = (Button)findViewById(R.id.btn_stop);
btn_start.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
startService(bg_service);
}
});
btn_stop.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
stopService(bg_service);
}
});
我在创建时使用
notificationManager = (NotificationManager)
getSystemService(NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.ic_launcher,
"A new notification", System.currentTimeMillis());
notification.flags |= Notification.FLAG_FOREGROUND_SERVICE;
Intent intent = new Intent(this, mainapp.class);
PendingIntent activity = PendingIntent.getActivity(this, 0, intent, 0);
notification.setLatestEventInfo(this, "...",
"...", activity);
notificationManager.notify(19314, notification);
此代码 在销毁时使用此代码
noficationManager.cancel(19314);
I have a service that create a notification when it is started.
And then ondestroy() i want it to be removed.
I just use .cancel(NOTIFICATION_ID);
It works great when it is a normal notification but when i am using ongoing event it just won't cancel it.
I did read something about that services doesn't stop if android have the resources for it, but how to overcome this?
I use this code to start the service
final Intent bg_service = new Intent(BackgroundService.class.getName());
btn_start = (Button)findViewById(R.id.btn_start);
btn_stop = (Button)findViewById(R.id.btn_stop);
btn_start.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
startService(bg_service);
}
});
btn_stop.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
stopService(bg_service);
}
});
I use this in on create
notificationManager = (NotificationManager)
getSystemService(NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.ic_launcher,
"A new notification", System.currentTimeMillis());
notification.flags |= Notification.FLAG_FOREGROUND_SERVICE;
Intent intent = new Intent(this, mainapp.class);
PendingIntent activity = PendingIntent.getActivity(this, 0, intent, 0);
notification.setLatestEventInfo(this, "...",
"...", activity);
notificationManager.notify(19314, notification);
And this in on destroy
noficationManager.cancel(19314);

如果可以的话，我会以不同的方式看待“持续”通知。
Service上有一些方法专门用于添加和删除“正在进行的”通知。Service.startForeground （int，通知）Service.stopForeground(boolean)也许您可以尝试从
onDestroy()调用stopForegroud(boolean)代码>方法优先...I would look at doing 'ongoing' notifications a bit differently if you can. There are methods that live on
Servicethat are dedicated to adding and removing an 'ongoing' notification.Service.startForeground(int, Notification)Service.stopForeground(boolean)Perhaps you could just try calling
stopForegroud(boolean)from youronDestroy()method first...
