Android – how do I get an image from another application’s notification?

I'm creating a notification management application. I want to get the notification content displayed by other applications. At present, I use this Code:

statusBarNotification.getNotification().extras.getString(Notification.EXTRA_TITLE);

And this:

statusBarNotification.getNotification().extras.getString(Notification.EXTRA_TEXT);

Read the title and text of the notice. But after a few hours, I couldn't find a way to get the image attached to the notice text. For example, the profile picture displayed in WhatsApp's notice. I knew it wasn't a small icon or a large icon. I checked it several times

Therefore, if anyone can help in any way, we will be very grateful

resolvent:

I assume you use notificationlistenerservice to listen to notifications from other applications

In the notificationservice class, in the additional notification.extra_ SMALL_ Extract the icon resssource ID from icon and access other app packages to get drawable

Notification.EXTRA_ Picture contains the large image sent in the notification:

public class NotificationService extends NotificationListenerService {

    Context context;

    @Override

    public void onCreate() {
        super.onCreate();
        context = getApplicationContext();

    }

    @Override
    public void onNotificationPosted(StatusBarNotification statusBarNotification) {

        // a notification is posted

        String pack = statusBarNotification.getPackageName();

        Bundle extras = statusBarNotification.getNotification().extras;

        int iconId = extras.getInt(Notification.EXTRA_SMALL_ICON);

        try {
            PackageManager manager = getPackageManager();
            Resources resources = manager.getResourcesForApplication(pack);

            Drawable icon = resources.getDrawable(iconId);

        } catch (PackageManager.NameNotFoundException e) {
            e.printStackTrace();
        }

        if (extras.containsKey(Notification.EXTRA_PICTURE)) {
            // this bitmap contain the picture attachment
            Bitmap bmp = (Bitmap) extras.get(Notification.EXTRA_PICTURE);
        }

    }

    @Override

    public void onNotificationRemoved(StatusBarNotification statusBarNotification) {
        //call when notification is removed
    }
}
