android - How to handle gson error

In my application if you click on the button then it calls the web service for the response and after mapping this response to some class using GSON at the time of mapping I'm getting the following error:

com.google.gson.JsonParseException: The JsonDeserializer com.google.gson.DefaultTypeAdapters$CollectionTypeAdapter@44c51f20 failed to deserialized json object

How to handle it. can anybody help me

My Code

private OnClickListener exit3Listener = new OnClickListener(){

    if(!exit3status){   
        System.out.println("exit3 visible");
        //System.out.println("size"+RB_Constant.upcomingexits_obj.response.size());
        // Web service calling for exit restaurants.
        Exitexpand_pd = ProgressDialog.show(RB_UpcomingExits.this, "", "Please wait...", true);
        Thread t = new Thread(){

                    ExitRestaurantsResponse = getExitsRestaurants();
                    System.out.println("exit3response"+ExitRestaurantsResponse);
                } catch (SoapFault e) {

By using a try-catch-block?

try{
  // Try your GSON thing
} catch (JsonParseException e){
  // Do your Error handling
}
