Служба Accessibilty не запущена

Question

У меня есть сервис специальных возможностей, который я использую для отслеживания использования некоторых приложений и информирования пользователей. Все работало нормально. Не уверен, вдруг моя служба доступности перестала работать. Это даже не начало. Разрешение предоставлено. Но служба все равно не запускается.

в файле манифеста

<service android:name=".Services.AutoStartReceiverService" android:enabled="true"></service>

        <service
            android:name=".Services.WindowChangeDetectingService"
            android:label="@string/accessibility_service_name"
            android:enabled="true"
            android:exported="false"
            android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE">
            <intent-filter>
                <action android:name="android.accessibilityservice.AccessibilityService" />
            </intent-filter>

            <meta-data
                android:name="android.accessibilityservice"
                android:resource="@xml/accessibilityservice" />
        </service>

Код услуги доступности:

                                    }

    }
}

в строковом файле:

<string name="accessibility_service_name">@string/app_name</string>
    <string name="accessibility_service_description">ভার্চুয়াল অ্যান্টিভাইরাস er je karone ei permission ti dorkar</string>

XML-файл службы доступа:

<?xml version="1.0" encoding="utf-8"?><!-- These options MUST be specified here in order for the events to be received on first
 start in Android 4.1.1 -->
<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:accessibilityEventTypes="typeWindowStateChanged"
    android:accessibilityFeedbackType="feedbackGeneric"
    android:accessibilityFlags="flagIncludeNotImportantViews"
    android:description="@string/accessibility_service_description"
    tools:ignore="UnusedAttribute" />

я получаю разрешение на доступ к моей основной деятельности, например:

accessPermissionButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(android.provider.Settings.ACTION_ACCESSIBILITY_SETTINGS);
                startActivityForResult(intent, 0);
            }
        });

И заметил, что он отлично работает на симуляторе.

Изменил xml службы доступа к ниже, и он снова начал работать

<?xml version="1.0" encoding="utf-8"?>
<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"
    android:description="@string/accessibility_service_description"
    android:accessibilityEventTypes="typeWindowStateChanged"
    android:accessibilityFlags="flagDefault"
    android:accessibilityFeedbackType="feedbackSpoken"
    android:notificationTimeout="100"
    android:canRetrieveWindowContent="true"
    android:settingsActivity="com.example.android.accessibility.ServiceSettingsActivity"
    />
