How can I make my application work instead of the Android launcher?

Question

Android

Hello, the next task is to remove the standard launcher from the firmware, all possible software and services and run your apk as a launcher.
You need a tablet just to work with one program.
Tell me how to do the following:
1) My application was launched after Android was loaded (similar to how the launcher does it)
2) Remove the ability to exit from the application
3) If the application is frozen or merged, you need to restart (as in the launcher)
4) And also tell me how to remove the top and bottom drain in android (tablet)
