So what's Your problem?
That arrow looks the way you want? Then read this.
Or that it is displayed on the home screen? Well you gave true to the method.
Shouldn't it appear on the home screen? - maritza_Lueilwitz commented on September 26th 19 at 07:36
In Android there is no notion of the main screen. Simply put, all screens are equal. The application consists of components. Aktiviti(screen) is one of them. There is a starter activity. You can make several starting activities. How can you make the arrow the icons in the start-up activiti. This is normal. If you don't need it - remove. - Baby.Waters commented on September 26th 19 at 07:39
