Read Notification Bar title, message using Accessi

Question

Using Accessibility Service I am being able to read notification bar title & message, the issue I am facing is when first notification appear I am reading all these perfectly but after first notification & onward I am only getting title & text "you have 2 messages" and so on, not the entire message. Waiting for your expert advice.

Code :

@Override
    protected void onServiceConnected() 
    {
        Log.d("AccessibilityServiceNotification", "ServiceConnected");
    try
    {
        AccessibilityServiceInfo info = new AccessibilityServiceInfo();

        info.eventTypes = AccessibilityEvent.TYPE_NOTIFICATION_STATE_CHANGED;

        info.feedbackType = AccessibilityServiceInfo.FEEDBACK_ALL_MASK;

        info.notificationTimeout = 100;

        setServiceInfo(info);
    }
    catch(Exception e)
    {
        Log.d("ERROR onServiceConnected", e.toString());
    }
    }

    @Override
    public void onAccessibilityEvent(AccessibilityEvent event) 
    {
        try 
        {
            LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);

            Parcelable data = event.getParcelableData();

            if(data !=null)
            {
                Notification notification = (Notification) data;

                RemoteViews remoteView = notification.bigContentView;

                ViewGroup localView = (ViewGroup) inflater.inflate(remoteView.getLayoutId(), null);

                remoteView.reapply(getApplicationContext(), localView);

                Resources resources = null;

                PackageManager pkm = getPackageManager();

                try 
                {
                    resources = pkm.getResourcesForApplication("com.user.package");
                }
                catch (NameNotFoundException e) 
                {
                    e.printStackTrace();
                }

                if (resources == null)
                    return; 

                int TITLE = resources.getIdentifier("android:id/title", null, null);

                int INBOX = resources.getIdentifier("android:id/big_text", null, null);

                int TEXT = resources.getIdentifier("android:id/text", null, null);

                String packagename = String.valueOf(event.getPackageName());

                title = (TextView) localView.findViewById(TITLE);

                inbox = (TextView) localView.findViewById(INBOX);

                text = (TextView) localView.findViewById(TEXT);

                Log.d("NOTIFICATION Package : ", packagename);

                Log.d("NOTIFICATION Title : ", title.getText().toString());

                Log.d("NOTIFICATION You have got x messages : ", text.getText().toString());

                Log.d("NOTIFICATION inbox : ", inbox.getText().toString());
        }
        }
        catch(Exception e)
        {
            Log.e("onAccessibilityEvent ERROR", e.toString());
        } 
    }

Example Notification 1:

package : com.whatsapp, title : Hello, message: How are you

Example Notification 2:

package : com.whatsapp, title : Hello, message: you have 2 messages (instead of : What are you doing)

Answer 1

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.

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> 

Answer 2

It is rather simple by using the extras field in the notification. The key that holds the expanded text lines is EXTRA_TEXT_LINES.

This is working for me:

Notification notification = (Notification) event.getParcelableData();
CharSequence[] lines = notification.extras.getCharSequenceArray(Notification.EXTRA_TEXT_LINES);
int i = 0;
for(CharSequence msg : lines)
{
    Log.d("Line " + i, (String) msg);
    i += 1;
}

Answer 3

This code works perfectly for me:

List<String> msgs = new ArrayList<String>();
msgs.add("Info: " + notif.extras.getString(Notification.EXTRA_INFO_TEXT));
msgs.add("Title: " + notif.extras.getString(Notification.EXTRA_TITLE));
msgs.add("Text: " + notif.extras.getString(Notification.EXTRA_TEXT));

I researched some days to get this method, i have tested it on Android 4.4, 5.5 and 6.0. You can also use the method

if(event.getEventType() == AccessibilityEvent.TYPE_VIEW_TEXT_CHANGED){  
  if(event.getPackageName().toString().equalsIgnoreCase("com.whatsapp")){
Log.d("msg", event.getText().toString().replace("[", "]").replaceAll("]", ""), Logger.EXTRA_LOG);
 }
}

Then you can get all written messages. Hope it helps.
