You can't load any of your Android Application when device is in the booting state. However if you are system kind of developer that loads ROM Data, then it might be possible.

As an android Developer all you can do is to make your application works only once the booting process is completed. Nothing before it.

How it is possible? Can you explain? – user987362 Sep 17 '12 at 09:45
Its only possible if you do machine coding, like Assembly. Also you require special tool to load such code in to Android Device. – Lucifer Sep 17 '12 at 09:53

You can use android.intent.action.BOOT_COMPLETED intent and show your login screen

if you are tried to implement Device boot up means, first of all you must consider the device Android OS version. If you have OS version 3.1+ means it won't works, the BOOT_COMPLETED permission is not called in those OS's. If you are using below 3.1 means, you can enable device boot up functionality. Refer this question for your problem Device Boot up. I met the same problem in my application too.
