仅限Android 4.0设备上的Phonegap getCurrentPosition超时

Question

I have developed an app which is now live on Google Play store. The app uses the getCurrentPosition method to get the current location of a user.

I have tested on a few devices, and the code works perfectly. Those devices being the Nexus 4, Nexus 5, Samsung Galaxy S3 and S4. Perfect.

I have now found issues with the app on Android devices lower than 4.1 (namely 4.0.4, which seems the most used version other than those mentioned).

The app constantly returns a timeout error. I know location services are switched on on the device.

I have amended the options for getCurrentPosition and included a maximumAge , timeout and enableHighAccuracy . I have tried all sorts of options; from reasonable timeouts/ages, low timeouts/ages to high timeouts/ages. I have tried turning enableHighAccuracy on ( true ) and off ( false ) in all permutations. The timeout is being taken into account (eg. the error callback isn't being hit until timeout is reached).

There are a few similar threads on StackOverflow, but none match my problem. I have tried turning the device off, deleting and re-adding the app, and recompiled it several times. Same issue.

The device being tested is a HTC Sensation, but I have also tried on a HTC Wildfire, and there are similar bug reports coming from users out in the wild - all the same.

Below is sample code, but like I say, I've tried all sorts of options (higher age than timeout, higher timeout than age, high accuracy on and off in both cases, etc).

if (navigator.geolocation) navigator.geolocation.getCurrentPosition(function(pos) {
        console.log('Working...');
    }, function(error, msg) {
        console.log(error.code + ' - '+ error.message);
    },
    { maximumAge: 90000, timeout: 9000, enableHighAccuracy: false });

LogCat spits out: 3 - Position retrieval timed out. at file:///[...] 3 - Position retrieval timed out. at file:///[...]

Update : Changing to watchPosition has no effect, the device will not find the location still.

Answer 1

This was a problem with the device rather than a problem with Android (possibly) or Phonegap (certainly). Location based services were not working on the default Android Browser, or anything that uses the native browser (Maps app DOES work).

I fixed this on the device by turning off location services, rebooting the device and restarting all location services, forcing re-acceptance of terms/certificates/etc. Location services then sprung into life, browser found where I was and the app worked as it should.

Found a few people complaining of this online, and I've experienced it on more than one device running the same Android version.

For me, the geolocation plugin had not successfully installed for some reason. Run cordova plugins list to make sure that cordova-plugin-geolocation is there. If not, run cordova plugins add cordova-plugin-geolocation . Sometimes removing and re-adding a plugin or entire platform will fix errors as well.
