当我尝试调试它时，我的应用程序崩溃，但在运行模式下运行正常。我查看了堆栈跟踪，我知道这是由于回调代码而发生的。
为什么应用程序仅在调试模式下崩溃？
这是片段：
public class MoviePosterFragment extends Fragment {
private void updateMoviePosters(final RecyclerView rv) {
MovieAPI mMovieAPI = NetworkAPI.createService(MovieAPI.class);
Callback<movieGeneral> callback = new Callback<movieGeneral>()
{
@Override
public void success(movieGeneral mMovieGeneral, Response response) {
updateMovieGrid(rv, mMovieGeneral);
Toast.makeText(getActivity(), "callback success!",
Toast.LENGTH_LONG).show();
}
@Override
public void failure(RetrofitError error) {
int a =0;
//show error message
//set adapter to null
Toast.makeText(getActivity(), "fail!",
Toast.LENGTH_LONG).show();
}
};
mMovieAPI.fetchPopMovies(MOST_POPULAR, API_KEY, callback);
}
}
网络API：
public class NetworkAPI {
//Volatile keyword ensures that multiple threads handle the unique/instance correctly
private volatile static NetworkAPI uniqueInstance;
public static final String POP_MOVIES_URL = "http://api.themoviedb.org/3/discover/movie?";
private final String API_KEY = "xxxxxxxxxxxxxxxxxxxxxx";
final String SORT_PARAM = "sort_by";
final String PAGE = "page";
final String KEY = "api_key";
private static RestAdapter.Builder builder = new RestAdapter.Builder()
.setEndpoint(POP_MOVIES_URL) //API endpoint
.setClient(new OkClient(new OkHttpClient())); //setClient: the HTTP client used for requests
public static <S> S createService(Class<S> serviceClass) {
RestAdapter adapter = builder.build();
return adapter.create(serviceClass);
}
}
接口：
public interface MovieAPI
{
@GET("/3/discover/movie")
void fetchPopMovies
(
//@Query: specifies the query key name with the value of the annotated parameter.
@Query("sort_by") String SORT_PARAM,
@Query("api_key") String API_KEY,
retrofit.Callback<movieGeneral> cb //last parameter must be a Callback so API call can run asynchronously
);
}
