我一直试图在我的Android应用中更新7digital SDK，而且我已经碰壁了。我对search的电话给了我以下的崩溃：

我用来拨打search的代码是：
SDIApi myApi = MyApplication.getSDIApi();
SDIApi.Track myTrack = myApi.track();
final SDITrackSearchRequest.Result searchResults = myTrack.search(artist.mName + " " + track.mTrackName);
...当我尝试跨过search行时，崩溃和堆栈跟踪出现了。有谁知道这里会发生什么？自从使用旧版本的库以来，我没有改变我的非库代码（并且没有错误）。
