Setting permission as boot_completed works but before my application is loaded, the homescreen is shown for 5 seconds. How to disable android from showing any homescreen launcher before my application

Answer 1

This mode is called kiosk mode, and android has provision for running devices in Kiosk mode, you can refer to this guide for the complete set up. Basically what you do is set up your app to listen to the RECEIVE_BOOT_COMPLETED broadcast and disable all actions such as back button home button minimize buttons etc. Also don't forget to set up an exit mechanism. Just follow the guide and you should be fine.
