BroadcastReceiver for BOOT_COMPLETED is too slow

Question

The below is my manifest file.

Answer 1

Is there any what to start the application immediately after reboot?

No.

There are many, many apps that want to get control at boot time. How quickly yours will get its turn will depend on many variables, such as the number of installed apps, the CPU speed of the device, the amount of system RAM on the device, etc.

Also, starting an activity from a BroadcastReceiver at boot time is fairly evil. If you want to be the first thing the user sees after a reboot, write a home screen implementation.
