### Unlock and wake-up
A wake-up turns on the screen while unlocking moves the app to foreground even the device is locked.
```js
// Turn screen on
cordova.plugins.backgroundMode.wakeUp();
// Turn screen on and show app even locked
cordova.plugins.backgroundMode.unlock();
```
### Notification
To indicate that the app is executing tasks in background and being paused would disrupt the user, the plug-in has to create a notification while in background - like a download progress bar.
