Question

我在我的应用中通过Retrofit轻松调用了Google Map API 我在GooglePlay控制台和一部手机中看到了错误，但无法在模拟器和其他手机上重现该错误-一切正常。这是java.lang.IndexOutOfBoundsException

只有在应用保持几天或几周不变的情况下，才会出现类似错误的提示而且PlayConsole表示该问题在低于7.0的Android版本中不会出现

请在下面显示代码当“ try-catch”循环开始时，Stacktrace指示该行上的错误。我以为我只是有错误，因为当没有数据响应时，我试图“ get（0）”。但是我已经重现了这种行为，并且我的“ catch”块可以完美地解决此问题，该应用并未崩溃

毕竟堆栈跟踪为什么指示字符串76而不是实际发生调用的字符串77？

这是有错误的方法

    Call<Geocod> response = geocoding_interfaces.CoordinatesFactory.getInstance().getCoordinates(coordinates, private_key);

        try {      //HERE IS STRING 76 
            incomelocation = response.execute().body().getResults().get(0).getGeometry().getLocation();
            askinglocation = from_loc_to_string(incomelocation);
        } catch (IOException | IndexOutOfBoundsException e) {
            askinglocation = locations;
        }

这是回调

   @Override
        public void onLoadFinished( Loader<List<Datum>> loader, List<Datum> data) {
            int id = loader.getId();
            if (id == R.id.weather_loader_id) {
                if (data != null) {
                      // here some methods to work with data
                } else
                {
                     // here some methods to work errors out 
                }

这是主要的改装界面
