无法在Android平台中调用地理位置插件

Question

We use Worklight 6.2 or MobileFirst Foundation 7.0 and want to use navigator.geolocation.getCurrentPosition to get the GPS position, but there is not any response and no error, does anyone know why?

It works on older versions.

Answer 1

If you're not getting not success nor failure, and since you did not supply your implementation, I am left in thinking that you did not implement it correctly.

I tested the below in the Android Emulator in MFPF 7.0, and it worked:

common\\main.js:

function wlCommonInit(){
    var options = {
            enableHighAccuracy: true,
            timeout: 5000,
            maximumAge: 0
    };

    navigator.geolocation.getCurrentPosition(success, error, options);
}

function success(pos) {
     var crd = pos.coords;
      alert('Your current position is:' + crd.latitude + " " + crd.longitude + " " + crd.accuracy);
}

function error(err) {
      alert('ERROR(' + err.code + '): ' + err.message);
}

And of course also added the following two permissions in AndroidManifest.xml:

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

If you're also testing in the emulator and getting a timeout, either increase the timeout value or force the location change in the DDMS view in Eclipse: https://stackoverflow.com/a/23152773/1530814
