In what way do you close all network connections?

[iwaitu]

I found the point. When connection be disconnected, httpResponse.getBodyString() will return null.
so I modify JSONHelper.java to this, It work fine.

public class JSONHelper {

    public static JSONObject ToJSONObject(String text)
    {
        JSONObject json;
        if (text == null) {
            return null;
        }
        try {
            json = new JSONObject(text);
        } catch (JSONException e) {
            json = null;
        }
        return json;
    }
}

It seems to be same with your code ,but when I changed to this , It never be crashed again. I don't know why...

By the way , I disconnected all network by disable mobile wifi and close gprs .

Modify JSONHelper.java to this, it will return null when it throw some Exception, and write Exception to Log if it have other Exception.

public class JSONHelper {

public static JSONObject ToJSONObject(String text)
{
    JSONObject json = null;
    try {
        json = new JSONObject(text);
    } catch (JSONException e) {
    } catch (NullPointerException e){
    } catch (Exception e){
       //Log it
    }
    return json;
}

}

can you fix this and include in signala-longpolling-0.20.aar? I'm use Eclipse Juno, and cant modify .class file without decompile.
