I know there has been a lot of questions on the site about the IOExeption : service not available.....I have checked all the answers i could find on the subject... i'm running it as async task which seems to be working fine but still getting the same exception.
I have used isPresent() on previous attempts although it is not in the following code and i am using the same phone. i have the internet permission. i have tried to change target to google api to see if that was the problem but it made no difference.
This is a vital part of a forth year project so any help would be serious. ps never worked with java or android before very recently so forgive any rookie looking coding ty..

heres the logcat

Geocoder.isPresent() can return false on some devices.
If it returns true and you still have problems you can create your own Geocoder by using The Google Geocoding API
I made a platform-independent Geocoder library which is available at github and Maven Central
dependencies {
compile 'com.github.doctoror.geocoder:library:[version]'
}
Edit: the previous answer contained a short example implementation of implementing Geocoder.
