Clear granted Expo.Permissions, show Permissions popup again onButtonPress

Expo SDK
1

I noticed that Expo automatically saves a cache of the permission granted by the user.
For eg: I granted a Permissions.CAMERA, the next time the app is run on Expo, it automatically calls a status of granted or denied.

Now when the permission is denied, I have a button to show the Permissions popup again, but it doesn’t work, cause the permission is already set to denied. Is there any way to clear the permissions or the async/await function? Thanks.

componentDidMount() {
      this.getCameraPermission();
    }

onButtonPress() {
    this.getCameraPermission();
  }

async getCameraPermission() {
    const { status: existingStatus } = await Permissions.getAsync(Permissions.CAMERA);
    let finalStatus = existingStatus;
    if (existingStatus !== 'granted') {
      const { status } = await Permissions.askAsync(Permissions.CAMERA);
      finalStatus = status;
    }

    if (finalStatus !== 'granted') {
      return;
    } else if (finalStatus === 'granted') {
      Actions.showCamera();
    }
  }

Hi! Can you tell us which platform you’re using? On Android the user can select “Never ask for this permission again” which means that askAsync will return without prompting the user.
