I have installed onesignal push on my ionic app, it worked well but when i send web push and by clicking on that specific notification on my Android device it takes me to external browser to open that notification.
Now I want what ever type of notification i will send from one signal to my app it should only open app, not browser not more than that.
You must omit setting a Launch URL on the OneSignal dashboard or the
urlfield if you are using the REST API. You will need to send two different notifications if you need to still direct the user to a specific URL for your web push users.
