Android Accessibility Service Detect Notification

How to read Notifications using Accessibility Services

https://developer.android.com/reference/android/view/accessibility/AccessibilityRecord#getParcelableData()

Different types of event carry different data; For this particular kind you use getParcelableData() to get the notification body.

case AccessibilityEvent.TYPE_NOTIFICATION_STATE_CHANGED:
                Notification notification = (Notification) accessibilityEvent.getParcelableData();
                if (notification == null) return;
                String title = notification.extras.getCharSequence(Notification.EXTRA_TITLE).toString();
                String text = notification.extras.getCharSequence(Notification.EXTRA_TEXT).toString();
                String text2 = notification.extras.getCharSequence(Notification.EXTRA_BIG_TEXT).toString();
                String package_name = accessibilityEvent.getPackageName().toString();
                break;

Android accessibility service detect notification

Accessibility services in Android 4.0 and above can behave strangely if there is no accessibility-service meta-data tag defined in the manifest. Try defining the meta-data as in the examples below. You should continue to use setServiceInfo() to maintain backward compatibility with pre-4.0 devices.

Also, I would recommend specifying a feedback type that is specific to your service, rather than using "all".

AndroidManifest.xml

    <service
        . . .
        android:name=".NotificationService"
        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>

res/xml/accessibilityservice.xml

<?xml version="1.0" encoding="utf-8"?>
<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"
    android:accessibilityEventTypes="typeNotificationStateChanged"
    android:accessibilityFeedbackType="feedbackAllMask"
    android:notificationTimeout="100" />

There was an error in your feedbackType. Corrected below. Still, consider using a more specific feedback type.

NotificationService.java

@Override
protected void onServiceConnected() {
    AccessibilityServiceInfo info = new AccessibilityServiceInfo();
    info.eventTypes = AccessibilityEvent.TYPE_NOTIFICATION_STATE_CHANGED;
    info.feedbackType = AccessibilityServiceInfo.FEEDBACK_ALL_MASK;
    info.notificationTimeout = 100;
    setServiceInfo(info);
}

Android accessibility service

I added a meta data element inside the service tag

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

And in the xml resources file I have

<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"
                       android:accessibilityEventTypes="typeNotificationStateChanged"
                       android:accessibilityFeedbackType="feedbackAllMask"
                       android:notificationTimeout="100" />

Cannot access notification through Android AccessibilityService

I got it working on L though, it's not really working on api 16, I tested on one. Can anyone suggest an addition to make it work on api 14+

Accessibility service notification removed

You should use NotificationListenerService for this purpose (To catch Notification of application NotificationListenerService is another option like Accessibility Service).

Where onNotificationRemoved gives StatusBarNotification into parameter. By reading this param you can get all information about notification.

You can read NotificationListenerService-Example for more details.

Read Notification Bar title, message using Accessibility Service Programmatically

try this, below code works for me -

Notification notification = (Notification) event.getParcelableData();
RemoteViews views = notification.contentView;
Class secretClass = views.getClass();

try {
    Map<Integer, String> text = new HashMap<Integer, String>();

    Field outerFields[] = secretClass.getDeclaredFields();
    for (int i = 0; i < outerFields.length; i++) {
        if (!outerFields[i].getName().equals("mActions")) continue;

        outerFields[i].setAccessible(true);

        ArrayList<Object> actions = (ArrayList<Object>) outerFields[i]
                .get(views);
        for (Object action : actions) {
            Field innerFields[] = action.getClass().getDeclaredFields();

            Object value = null;
            Integer type = null;
            Integer viewId = null;
            for (Field field : innerFields) {
                field.setAccessible(true);
                if (field.getName().equals("value")) {
                    value = field.get(action);
                } else if (field.getName().equals("type")) {
                    type = field.getInt(action);
                } else if (field.getName().equals("viewId")) {
                    viewId = field.getInt(action);
                }
            }

            if (type == 9 || type == 10) {
                text.put(viewId, value.toString());
            }
        }

        System.out.println("title is: " + text.get(16908310));
        System.out.println("info is: " + text.get(16909082));
        System.out.println("text is: " + text.get(16908358));
    }
} catch (Exception e) {
    e.printStackTrace();
}

hope it will help you.

EDITED

create a folder named xml inside your res folder - create a xml in it named -"accessibilityservice" and paste below code -

<?xml version="1.0" encoding="utf-8"?>
  <accessibility-service  xmlns:android="http://schemas.android.com/apk/res/android"
 android:accessibilityEventTypes="typeNotificationStateChanged"
 android:accessibilityFeedbackType="feedbackSpoken"
 android:notificationTimeout="100" />

and inside manifest update your service tag to below code -

<service
        android:name=".YourServiceClassName"
        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> 

Android: How do you check if a particular AccessibilityService is enabled

I worked this one out myself in the end:

public boolean isAccessibilityEnabled() {
    int accessibilityEnabled = 0;
    final String LIGHTFLOW_ACCESSIBILITY_SERVICE = "com.example.test/com.example.text.ccessibilityService";
    boolean accessibilityFound = false;
    try {
        accessibilityEnabled = Settings.Secure.getInt(this.getContentResolver(),android.provider.Settings.Secure.ACCESSIBILITY_ENABLED);
        Log.d(LOGTAG, "ACCESSIBILITY: " + accessibilityEnabled);
    } catch (SettingNotFoundException e) {
        Log.d(LOGTAG, "Error finding setting, default accessibility to not found: " + e.getMessage());
    }

    TextUtils.SimpleStringSplitter mStringColonSplitter = new TextUtils.SimpleStringSplitter(':');

    if (accessibilityEnabled==1) {
        Log.d(LOGTAG, "***ACCESSIBILIY IS ENABLED***: ");

        String settingValue = Settings.Secure.getString(getContentResolver(), Settings.Secure.ENABLED_ACCESSIBILITY_SERVICES);
        Log.d(LOGTAG, "Setting: " + settingValue);
        if (settingValue != null) {
             TextUtils.SimpleStringSplitter splitter = mStringColonSplitter;
             splitter.setString(settingValue);
             while (splitter.hasNext()) {
                 String accessabilityService = splitter.next();
                 Log.d(LOGTAG, "Setting: " + accessabilityService);
                 if (accessabilityService.equalsIgnoreCase(ACCESSIBILITY_SERVICE_NAME)){
                     Log.d(LOGTAG, "We've found the correct setting - accessibility is switched on!");
                     return true;
                 }
             }
        }

        Log.d(LOGTAG, "***END***");
    }
    else {
        Log.d(LOGTAG, "***ACCESSIBILIY IS DISABLED***");
    }
    return accessibilityFound;
}
