Android-programmatically bypass remove default lock screen

Question

I've defined a default application as a launcher with a HOME intent so it always runs when I boot the device. But I still see the default lock screen(with clock) first when I power up.

Is there a way to remove the lock screen entirely when the device powers up?

Using following command you can disable the existing lockscreen of course if it doesn't contain any security(like patterns and pin code):

KeyguardManager keyguardManager = (KeyguardManager)getSystemService(Activity.KEYGUARD_SERVICE);
KeyguardLock lock = keyguardManager.newKeyguardLock(KEYGUARD_SERVICE);
lock.disableKeyguard();

you need also to declare permission in manifest:

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

Than detect the user presence (clicking on Power Button):

<receiver android:name=".Receive">
    <intent-filter android:enabled="true" android:exported="false">
        <action android:name="android.intent.action.USER_PRESENT" />
    </intent-filter>
</receiver>

and start custom lockscreen Activity
