Android pattern lock/unlock screen programmatically

Part of my app is to lock screen using a certain pattern the user chooses and unlocks it with the same pattern. I wish to use the same android default Pattern lock screen. I want the user to be able to set up multiple patterns and unlock the screen with these patterns.

Any ways I can do that? Is there some intent or class I can call to do that? Or do I have to develop such mechanisim from scratch? I have no idea where to start with

Heeeelp! Thank you

You can call lockNow method by DevicePolicyManager.

public class MobileDeviceAdminReceiver extends DeviceAdminReceiver {


}

ComponentName deviceAdminReceiver = new ComponentName(this, MobileDeviceAdminReceiver.class); // Register BroadcastReceiver in manifest;
Intent intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);// admin permission intent
intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN,deviceAdminReceiver);

Or create your custom lock screen that monitoring top activity and block it.
