Need to start app immediately after the boot completed

I need to know why my app didn't run immediately after booting in android real phone? My app runs but after a few second of booting.

My Code is 

public class AutoStart extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub
         if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)){
                Intent i = new Intent(context, MyActivity.class);
                i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                context.startActivity(i);
            }
    }

}

My activity is running, but after few Seconds of the boot completed. Is it Possible to reduce this few second?

I want to run my app immediately. I Don't want to allow user to access the phone.

I run through this problem too. To anyone still searching for solution:

Consider turning your app into home launcher. Make changes in the manifest:

Add to your activity

android:launchMode="singleTask"

Add to intent filter in activity

<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.HOME" />

After that it will launch immediately with system, not showing to user anything else.

This can increase you priority but still there would be some delay. Since android first load its OS and the all the other activity starts.

<receiver
    android:name=".AutoStart"
    android:enabled="true"
    android:exported="true"
    <intent-filter android:priority="1000">
        <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</receiver>

Android system does lot of work on boot completed. hence the intent might be delayed. Depending on the phone capabilities, the intent delay times will vary.
