Location always instantly returns with a timeout

[jesseruder]

Ok we figured out how to reproduce this. Will fix it in the next release.

[jesseruder]

I think that's the same error @alexprice91. We're doing a release this week and we'll see if that fixes these issues.

@jesseruder It works for me in iOS and Android > 6. As for Android < 6, it works fine if the location is turned on. However, if the location on the phone is turned off, the app would keep waiting when running await Location.getCurrentPositionAsync({enableHighAccuracy: true}) and no error is triggered. Not sure if it is the intended behavior.

We ended up setting a timeout for this situation as shown below, but it would be nice if an error would be triggered with the message saying the phone's location is not available.

      await Promise.race([
          Location.getCurrentPositionAsync({enableHighAccuracy: true}),
          // 2s Timeout for Android phones system version < 6
          new Promise((resolve, reject) => setTimeout(()=>reject(new Error('timeout')), 2000)),
      ])
          .then(result => {
            console.log("location", location);
            location = result
          })
          .catch(error => {
            console.log("get location timed out", error);
          });

I've tried watchPositionAsync() too with the same code and it doesn't seem to be working either.

EDIT: I solved this by placing the function as an async function within the component itself

  async _getPosition() {
    const {Location, Permissions} = Exponent;
    const {status} = await Permissions.askAsync(Permissions.LOCATION);
    if (status === 'granted') {
      Location.getCurrentPositionAsync({enableHighAccuracy: true}).then((position) => {
        this.setState({lon: position.coords.longitude, lat: position.coords.latitude});
        this.callAPI();
        }).catch((e) => {
         // this one is firing the error instantly
          alert(e + ' Please make sure your location (GPS) is turned on.');
        });

    } else {
      throw new Error('Location permission not granted');
    }
  }

This is how I am calling it.

componentDidMount() {
    this._getPosition();
}

Thanks for the information. We're heard multiple reports of this but don't hit it on our devices. Will try your code.

@jesseruder I am getting the error:

{"framesToPop":1,"code":"E_TIMEOUT"}

Is this related?

[jesseruder]

Should be fixed. Can you try it out and let me know?

[nikki93]

This should be fixed in SDK 18, will close once released and confirmed by users.

[nikki93]

Released! @ciokan @andrewrd @alexprice91 @ChenLi0830 Let me know if this is still happening for you in SDK 18.

[atinder]

still happening on sdk 18.0.4

Same happens to me.
Android 5.1.1

Edit:
It happens when the location in android settings is set to GPS only, but it works if it's set to use both wi-fi, gps, ...
