Maintain screen visibility while using the web application

Currently working on a web app that utilizes Three.js (Javascript) and the VR features for mobile devices, with a focus on Android. One issue I've encountered is that after a while, the screen dims and shuts off. I've searched for an API to prevent this, but haven't had any luck finding information. Interestingly, when you visit and run their demos, the screen remains active. I attempted to analyze their code but couldn't locate the solution. How are they achieving this? Thank you.

Answer №1

To ensure your screen stays on, include a flag within the onCreate function of your activity.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
}

Answer №2

If you're using a Browser such as Chrome to run the app, it's not possible to prevent the screen from going to sleep since JavaScript cannot modify device behavior.

To achieve this functionality, you can opt for a third-party app like KeepScreenOn (), or embed the app in a WebView using a hybrid App framework like PhoneGap or Titanium. These frameworks allow you to utilize plugins, such as this one:
