I am trying to split a post on facebook. login, permission to publish works for the first time. if I remove the application from the facebook website, it doesn’t ask me to reinstall the login and “Publish on your behalf”, publish the permission window below, this is my code. Please help, what I did wrong. I have tried a lot, but not working properly. Thank you for your good advice, and therefore I can improve the work in Android. Below is my code ...
