I've encountered a particular issue in my Android app: • when a user clicks the login button, a progress bar appears to authenticate their credentials. • Following this, the main activity is displayed. • However, during this transition, an undesirable black screen briefly appears. • This situation persists until I clear the cache memory or reinstall the application. I am eager to find a permanent solution to this problem. Your assistance and time are greatly appreciated in helping me address this issue. Thank you for your support
