安卓：NotificationListenerService没有再创造 [英] Android: NotificationListenerService wasn't created again
本文介绍了安卓：NotificationListenerService没有再创造的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
应用程序崩溃，因为一些错误的第一次后，NLService创建并再次绑定，但第2次或第3次之后...，该NLService没有创建和约束的多，连复选框
设置＆gt;安全＆GT;通知使用权
被选中，我该怎么做这种情况呢？
NLService：

解决方案
不过有问题？
我在同样的情况，这似乎NLService不会是协作...
作为假的解决方法我已经注意到，如果你检查，并取消设置＆gt;安全＆GT;通知使用权在调试会话期间，把一个断点在OnCreate（），您可以拦截服务启动时，但还不是很清楚，为什么有时会停止...
另一种可能性是重新启动设备...
尝试也许你会找到一个方法来解决，我还在努力...
结果的更新
或许真的是在服务改变。
这是我的测试工作在多个设备（我已经尝试好几天）。
安装应用程序可以在启用设置的通知，访问和比你可以试试code后。

你可以看到文本添加的每个通知的发布或删除发生这种情况。现在，该服务是否正常工作我们可以做我们想要的。

尝试，并告诉它是否工作。
After the app crashed because of some bugs for the first time, the NLService was created and bound again, but after 2nd time or 3rd time..., the NLService wasn't created and bound any more, even the checkbox in
Settings > Security > Notification access
is checked, how can I do with this situation?
NLService:
import android.content.Intent;
import android.os.IBinder;
import android.service.notification.NotificationListenerService;
import android.service.notification.StatusBarNotification;
import android.util.Log;
public class NLService extends NotificationListenerService {
private String TAG = this.getClass().getSimpleName();
@Override
public void onCreate() {
super.onCreate();
Log.d(TAG, "==onCreate==");
}
@Override
public void onDestroy() {
super.onDestroy();
Log.d(TAG, "==onDestroy==");
}
@Override
public void onNotificationPosted(StatusBarNotification sbn) {
Log.i(TAG, "********** onNotificationPosted");
Log.i(TAG, "ID :"
+ sbn.getId()
+ "\t"
+ sbn.getNotification().tickerText
+ "\t"
+ sbn.getPackageName());
}
@Override
public void onNotificationRemoved(StatusBarNotification sbn) {
Log.i(TAG, "********** onNOtificationRemoved");
Log.i(TAG, "ID :"
+ sbn.getId()
+ "\t"
+ sbn.getNotification().tickerText
+ "\t"
+ sbn.getPackageName());
}
@Override public int onStartCommand(Intent intent, int flags, int startId){
Log.d(TAG, "==onStartCommand==");
return super.onStartCommand(intent, flags, startId);
}
@Override public IBinder onBind(Intent intent) {
Log.d(TAG, "==onBind==");
return super.onBind(intent);
}
@Override public void onRebind(Intent intent) {
super.onRebind(intent);
Log.d(TAG, "==onRebind==");
}
@Override public boolean onUnbind(Intent intent) {
Log.d(TAG, "==onUnbind==");
return super.onUnbind(intent);
}
}
and registered in manifest.xml
<service android:name="com.kpbird.nlsexample.NLService"
android:label="@string/app_name"
android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE">
<intent-filter>
<action android:name="android.service.notification.NotificationListenerService" />
</intent-filter>
</service>
解决方案
Still got the problem?
I am in the same situation and this NLService seems won't to be collaborative...
As a "fake" workaround I have notice that if you check and uncheck the Settings > Security > Notification access during a debug session and put a breakpoint in the onCreate() you can intercept when the service starts but is not so clear why sometimes stops...
Another possibility is to reboot the device...
try maybe you'll find a way to solve, I'm still trying...
UPDATE
Maybe something is changed in the service. This is my test that is working on multiple devices (I've try it for days).
After install the app you can enabling the notification access in settings and than you can try the code.

Here we declare and add the service with NotificationListener (name of the class that we create)

as you can see the text add every notification posted or removed that happens. Now that the service is working properly we can make what we want.
Try and tell if it works.
