IllegalStateException thrown sometimes resulting in app crash when searching for location (Google Maps)

Question

I have a map activity which uses Google Maps where it searches for the location and outputs the address of it. My problem is, it works most of the time, but sometimes when searching for the location, it crashes. This is my logcat:

According to http://developer.android.com/reference/android/location/Geocoder.html#getFromLocationName(java.lang.String, int):

getFromLocationName(...) throws an IllegalArgumentExceptionif locationName is null and an IOException if the network is unavailable or any other I/O problem occurs.

In your LogCat, we can see that getFromLocationName(...) is throwing an IOException:

java.io.IOException: Unable to parse response from server

So there you have it: the problem is that either the network is unavailable or another I/O problem occurred.
