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

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.

In your manifest:

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

And add Intent filter:

<receiver android:name=".BootReciever">
<intent-filter >
    <action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>

And then Now you can start your application's first activity from onReceive method of Receiver class:

if your device has been rooted, uninstall system applications on your device, but be careful that every app can not be uninstalled. install "Root-Uninstaller-Pro-8.3" app and do this. you must uninstall important system apps one by one and any time restart your device to see result until Achieve goal. if you uninstall an app that make your device Messed up, you should flash your device to restore apps and retry uninstallations. by this uninstallations, your boot time become too short and that 5 second will be disappear. good luck!
