android : location api asking for wifi
This is weird. I mean, I have strong network, and GPS is turned On, still it asks for Wifi !!
I'm using new Location Api with class FusedLocationProviderClient.
This is how I am checking if Location Settings are enabled or not:
private void checkIfLocationSettingsAreEnabled() {
LocationRequest locationRequest = new LocationRequest();
locationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);
locationRequest.setInterval(10000);
locationRequest.setFastestInterval(5000);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder();
builder.addLocationRequest(locationRequest);
builder.setAlwaysShow(true);
SettingsClient client = LocationServices.getSettingsClient(context);
Task<LocationSettingsResponse> locationSettingsResponseTask = client.checkLocationSettings(builder.build());
locationSettingsResponseTask.addOnSuccessListener(locationSettingsResponse -> {
getLastKnownLocation();
});
locationSettingsResponseTask.addOnFailureListener(e -> {
if (e instanceof ResolvableApiException) {
myLocationListener.onResolutionNeeded(e);
} else {
myLocationListener.onLocationFailure(e);
}
});
}
With the above code, I am able to get below image:
But then, after clicking OK, again I make call to checkIfSettingsAreEnabled() this shows another popup as below:
I wonder why enabling Wifi is mandatory, even if I am on desert safari, where there is no Wifi to connect to !!
Is there any way to Skip this Wifi option, and work as normal as Google Maps does ?
In fact, Google Maps uses priority PRIORITY_HIGH_ACCURACY and still once, the first settings dialog has been shown, it doesn't ask second time to turn on Wifi.
Solution
With the below solution, I am able to skip this Wifi Settings Dialog. This is not a perfect solution, but just a workaround till I find perfect solution.
Problem was, even after clicking "Ok" on Settings Dialog, it returned result as Activity.RESULT_CANCELLED. Reason was, Wifi was still turned off. So, as a quick fix, made a check in result Activity.RESULT_CANCELLED, that if I could get Location by checking LocationSettingStates.
You can use my MyLocationUtils.java and Base classes LocationActivity.java or LocationFragment.java. Happy Coding..!!
