Android: NotificationListenerService was not created again
After the first application crash due to some errors the NLService was created and linked again, but after the second or third time ..., the NLService was no longer created or linked, not even the checkbox in
Settings > Security > Notification access
How can i do this?
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>

Still a problem?
I'm in the same situation and this NLService doesn't seem to cooperate ...
As a "fake" workaround , I noticed that if you check and uncheck the box Settings > Security > Notification access
during a debug session and put a breakpoint in onCreate (), you can intercept when the service starts, but it's not clear why sometimes it stops ...
Another possibility is to reboot the device ...
try it, maybe you can find a way to solve, I am still trying ...
UPDATE
Perhaps something has changed in the service. This is my test that works on multiple devices (I've tried it for a few days).
After installing the app, you can enable notification access in settings and 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'
}
The AndroidManifest.xml file . Here we declare and add a service with a NotificationListener (the name of the class to be created).
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="insert_your_package">

sendBroadcast(i);
}
@Override

}
as you can see the text adds every notification posted or removed that happens. Now that the service is working properly, we can do what we want.
Try to tell if it works.
