如何访问在Android应用程序中具有较高响应时间的API？

Question

I have a java API that is taking around 50 sec to return the response and improvement in API is not possible. User can not proceed in next page until the response is complete and it is kind of blocker in the android app which is using the API. Please suggest some alternate approach on this.

For example: we can have two table and API will return the data from table instead waiting for the result of query which is taking more time and we can spawn a thread to run the query in the background and update the table data with the result. Based upon time stamp in response data android app can know the data is old or latest and in case of old data they can request it again after some time to get the latest data.

Please let me know if the question or approach is not clear.

Answer 1

There is specific way of doing such things. There is a thing called Loader in android. CursorLoader is used for content providers. and AsyncTaskLoader for api calls

Answer 2

Try this

  if (BuildConfig.DEBUG) {
    HttpLoggingInterceptor httpLoggingInterceptor = new HttpLoggingInterceptor();
    httpLoggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
    httpClient.addInterceptor(httpLoggingInterceptor);
}

also add this dependencies in gradle app level

compile 'com.squareup.okhttp3:logging-interceptor:3.2.0'
