Android: NotificationListenerService wasn't created again

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>

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.

build.gradle file

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
       applicationId "your_application_id"
       minSdkVersion 18
       targetSdkVersion 23
       versionCode 1
      versionName "1.0"
}
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
}

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

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="insert_your_package">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity
            android:name=".AMain"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <service
            android:name=".NotificationListener"
            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>
    </application>

</manifest>

package insert_your_package;

import android.content.BroadcastReceiver;

        textView = (TextView) findViewById(R.id.textview);

        notificationReceiver = new NotificationReceiver();

        intentFilter.addAction("com.dev.name.test");

        registerReceiver(notificationReceiver, intentFilter);
    }

    @Override

        return true;
    }

    @Override

        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

    class NotificationReceiver extends BroadcastReceiver {

        @Override
        public void onReceive(Context context, Intent intent) {

            String temp = intent.getStringExtra("notification_event") + "\n" + textView.getText();

            textView.setText(temp);
        }
    }
}

NotificationListener.java file

package insert_your_package;

import android.content.Intent;
import android.service.notification.NotificationListenerService;
import android.service.notification.StatusBarNotification;
import android.util.Log;

public class NotificationListener extends NotificationListenerService {

    private String TAG = this.getClass().getSimpleName();

    @Override
    public void onNotificationPosted(StatusBarNotification sbn) {

        Log.i(TAG, "**********  onNotificationPosted");
        Log.i(TAG, "ID :" + sbn.getId() + "\t" + sbn.getNotification().tickerText + "\t" + sbn.getPackageName());

        Intent i = new Intent("com.dev.name.test");
        i.putExtra("notification_event", sbn.getPackageName() + " posted");

        sendBroadcast(i);
    }

    @Override
    public void onNotificationRemoved(StatusBarNotification sbn) {

        Log.i(TAG, "**********  onNotificationPosted");
        Log.i(TAG, "ID :" + sbn.getId() + "\t" + sbn.getNotification().tickerText + "\t" + sbn.getPackageName());

        Intent i = new Intent("com.dev.name.test");
        i.putExtra("notification_event", sbn.getPackageName() + " removed");

        sendBroadcast(i);
    }

    @Override
    public void onDestroy() {

        super.onDestroy();
    }
}

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.
