android ajax/gps connectivity problems

[Michael]

I am developing a hybrid mobile app with icenium. There are two troubling issues when testing on android devices:

1) many ajax calls fail and return a 404 error

2) attempts to grab gps coordinates using the geolocation feature fails.

There are no such issues on iOS devices. I am wondering if these are common issues, or if there is a procedure to follow for looking into the problems.

Hi Michael,

For the GPS issue try setting the enableHighAccurancy option to true and set maximumAge and timeout options to higher value like this:

navigator.geolocation.getCurrentPosition(onSuccess, onError, {
  enableHighAccuracy: true,
  timeout: 10000,
  maximumAge: 7000
});

Check if you haven't turned off some of the needed android Permissions in Project Properties.

If that doesn't do the trick you might try restarting the phone.



In order to help you with the ajax issue, I will need some more information. To where the ajax requests are sent (server, local file system)? Have you tried if a plain XMLHttpRequst works fine?

Looks like everything is running well for the time being.

Hi Kristian,

I have tried the same setting in my app but when I set enableHighAccuracy: true, application is not returning location and even I have set my geo location also on with all required permission, even when I am trying to run sample app then that is also not working. when I am setting it false that works correct.

Do you know what is the issue behind this?

Thanks,
Amit

Hi Jeremy,

The lack of strong GPS connection is probably the reason for this behavior on Android device.
You can try our KendoUI template available in AppBuilder clients and check its implementation.

Furthermore try watchPosition method (if you haven't) in order to update the current position and if this does not help refer your issue to Cordova's issue tracker as they are the developers of the plugin.

Meanwhile we will contact you if we find anything new on your case.
