Fullscreen Mode

Hi, I’m working on a simple game app. I am struggling to get my expo app into fullscreen mode. I have successfully hidden the status bar but I am facing problems with the navigation bar(Android). Help please :slight_smile:

Looks like support for hiding the navigation bar has been merged very recently. It looks like it’s a static configuration and not something you can control dynamically:


I think you’ll need to wait for SDK 35 if you don’t want to eject, but I don’t think you’ll have to wait very long for SDK 35, since the Expo team has said they plan to release it before iOS 13 is released and that’s expected soon

Awesome! Thank you so much, appreciate you :smiley:

It is not working for me tho. I have added it into my app.json file, and tried building it. It gave me an error saying that I should not have additional property “androidNavigationBar”. Here is my code:
“android”: {
“package”: “com.yokai.testing123”,
“androidNavigationBar”: {
“visible”: false

As I mentioned in my comment you will have to wait for SDK 35, which I think should include this change.

Otherwise you will have to build a version of Expo yourself that has the change included. I am not 100% sure how to do that, but maybe you can figure it out :slight_smile:. Here is the repository:

and the change was merged into the master branch in this commit:


okay okay, thanks for the help!

Well, apparently SDK 35 is out! Not sure why Medium removed their article about it… https://blog.expo.io/expo-sdk-35-is-now-available-7a73a065e71e

I think they’re still in the process of releasing it. Two days ago they said it was expected between Tuesday and Friday next week:

At least the docs are already updated! :smiley:

And now it has been released. Apparently they were a bit too pessimistic two days ago :grinning:

Yup! Going through the pain right now… Font.loadAsync error like last time.


1.- Delete the node_modules folder
2.- Delete the package-lock.json file
3.- Run npm install

Then run expo start -c

Did you guys manage to make the fullscreen work yet? I get this error:

Error: Problem validating fields in app.json. See https://docs.expo.io/versions/v35.0.0/workflow/configuration/

EDIT: When I try this

…Only androidStatusBar is recognized.
