1) Firstly determine whether it's a bug within the android, the third party libraries or your device, so you can know which way to proceed.
This answer gives a solution of how to do this:
If you have written (or are using) a plugin that in turn uses native C/C++ code through the NDK, this may indicate a bug in that native code.
Otherwise, this is a bug in the firmware of the device or emulator you are testing upon.
If you can reproduce this in an emulator, on a Nexus device with the original ROM, or on a variety of devices from different manufacturers, it is probably a bug in Android itself. In that case, please create a sample project that can reproduce the error, and post it along with the entire stack trace to http://b.android.com, the Android OS issue tracker.
If you are only encountering this on one device or one third-party ROM, it is probably a more specific bug -- your best bet is to contact the device manufacturer or ROM publisher with your symptoms.
There are these two questions which discuss the error you are receiving in detail:
Android Fatal signal 11 (SIGSEGV) at 0x636f7d89 (code=1). How can it be tracked down?
Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1) - PhoneGap
2) In terms of parsing your geobounds values (as it would seem is where the problem may lie), ensure you are handling your parsing between Gson and Json correctly, with the correct geobound values. It appears how you are storing the values is not in accord with how you are retreiving them.
From Mykong:
toJson() – Convert Java object to JSON
Gson gson = new Gson();
Staff obj = new Staff();
// 1. Java object to JSON, and save into a file
gson.toJson(obj, new FileWriter("D:\file.json"));
// 2. Java object to JSON, and assign to a String
String jsonInString = gson.toJson(obj);
fromJson() – Convert JSON to Java object
Gson gson = new Gson();
// 1. JSON to Java object, read it from a file.
Staff staff = gson.fromJson(new FileReader("D:\file.json"), Staff.class);
// 2. JSON to Java object, read it from a Json String.
String jsonInString = "{'name' : 'mkyong'}";
Staff staff = gson.fromJson(jsonInString, Staff.class);
// JSON to JsonElement, convert to String later.
JsonElement json = gson.fromJson(new FileReader("D:\file.json"), JsonElement.class);
String result = gson.toJson(json);
From this answer:
public class YourObject {
private String appname;
private String Version;
private String UUID;
private String WWXY;
private String ABCD;
private String YUDE;
//getters/setters
YourObject parsed = new Gson().fromJson(jsons, YourObject.class);
String jsons = "{'appname':'application', 'Version':'0.1.0', 'UUID':'300V', 'WWXY':'310W', 'ABCD':'270B', 'YUDE':'280T'}";
YourObject parsed = new Gson().fromJson(jsons, YourObject.class);
JsonObject object = new JsonParser().parse(jsons).getAsJsonObject();
object.get("appname"); // application
object.get("Version"); // 0.1.0

3) Ensure you are passing the correct values for your geobound co-ords.
This question Value does not fall within the expected range GeoboundingBox WinRT (although it is C# gives a good example of how to break down the components of information you are trying to store and retrieve.
The answer is straightforward.
var nw = new BasicGeoposition();
nw.Latitude = Max(pos.Coordinate.Latitude, pos2.lat);
nw.Longitude = Min(pos.Coordinate.Longitude, pos2.lng);
var se = new BasicGeoposition();
se.Latitude = Min(pos.Coordinate.Latitude, pos2.lat);
se.Longitude = Max(pos.Coordinate.Longitude, pos2.lng);
