我的proguard和Gson库有问题.我的代码是

AdServerResult result = (AdServerResult) new Gson().fromJson(json, 
      AdServerResult.class);

(我AdServerResult使用Gson库创建一个新对象)

我的AdServerResult班级:

public class AdServerResult {

    public ArrayList<AdServerObject> shorts ;
    public ArrayList<AdServerObject> longs ;

    public ArrayList<AdServerObject> getShorts() {
        return shorts;
    }
    public void setShorts(ArrayList<AdServerObject> shorts) {
        this.shorts = shorts;
    }
    public ArrayList<AdServerObject> getLongs() {
        return longs;
    }
    public void setLongs(ArrayList<AdServerObject> longs) {
        this.longs = longs;
    }

    //for debug
    @Override
    public String toString(){

        StringBuilder sb = new StringBuilder() ;

        if (shorts!=null && shorts.size()>0){
            for (AdServerObject s: shorts){
                sb.append("url: "+s.getPicture_url()); …
