How to Programmatically Force Your Android App into Fullscreen Mode (Notch-Friendly)

In the world of mobile app development, providing a seamless user experience is paramount. One common issue developers face is ensuring that their apps can display properly on modern devices that feature notches or display cutouts. If you're encountering problems with a blank or black screen surrounding the notch area when your app enters fullscreen mode, this post is for you. Here, we’ll walk you through the steps to programmatically force your Android app to enter fullscreen mode without worrying about those pesky notches!

Understanding the Issue

As smartphones evolve, so do their designs. Many Android devices now come with notches—small cutouts at the top of the screen to house front-facing cameras and sensors. These notches can complicate the fullscreen experience, as they may lead to parts of your app being obscured or displaying a black screen if not handled properly. The good news is, Android provides tools to help developers manage display cutouts effectively.

Step-by-Step Solution

Follow these steps to ensure your application adapts beautifully to notch-enabled devices when going fullscreen:

1. Create a New Values-v28 Folder

First, you’ll need to create a new folder within your resources directory. This folder will specifically target devices running Android 8.1 (API level 28) or higher:

Navigate to your res directory.

Create a new folder named values-v28.

2. Copy the Default Styles.xml File

Next, you will need to copy the existing styles.xml from your previous values directory into the new values-v28 folder. This allows you to customize styles specifically for devices that require notch handling.

3. Edit the Styles.xml File

Now, it’s time to update the copied styles.xml file. If you had already been using a theme, you can modify that; otherwise, create a new theme for your activity:

Open your styles.xml file located in the values-v28 folder.

Add or locate the activity's theme and include the following attribute:

4. Apply the Theme to Your Activity

Make sure that the newly created or modified theme is applied to your activity in your AndroidManifest.xml file:

Conclusion

That’s it! After making these changes, your app will no longer display a black screen around the notch area when entering fullscreen mode. By following these straightforward steps, you ensure a smooth and visually appealing experience for users on all modern Android devices.

Key Takeaway

When developing for devices with notches, it's crucial to adapt your application's layout programmatically. Implementing android:windowLayoutInDisplayCutoutMode with the value shortEdges is an effective solution that enhances user experience without compromising on design.
