Retrofit 2 synchronous call error handling for 4xx Errors

由 与世无争的帅哥 提交于 2019-12-04 19:13:54
问题 I'm using a android-priority-jobqueue and I use retrofit to make synchronous calls to my rest api but i'm unsure how to handle errors like 401 Unauthorized errors which I send back json stating the error. Simple when doing async calls but I'm adapting my app for job manager. below is a simple try catch for IO exceptions, but 401's 422's etc? How to do this? try { PostService postService = ServiceGenerator.createService(PostService.class); final Call<Post> call = postService.addPost(post);

OKHttp Authenticator custom http code other than 401 and 407

由 大憨熊 提交于 2019-12-04 19:08:17
I have oauth token implemented on server side but upon Invalid token or Token expirey i am getting 200 http status code but in response body i have {"code":"4XX", "data":{"some":"object"} When i try to read string in interceptor i get okhttp dispatcher java.lang.illegalstateexception closed because response.body().string() must be called only once. Also i read from here Refreshing OAuth token using Retrofit without modifying all calls that we can use OkHttp Authenticator class but it works only with 401/407 i havent triedn as i will not get this. Is there any way we can customize Authenticator

Rx 2 Android what is better Single or Observable for api calls?

由 岁酱吖の 提交于 2019-12-04 16:25:49
问题 when we use retrofit2 for doing API rest calls with Rx, What is the best approach to use, Single or Observable? public interface ApiService{ Single<Data> getDataFromServer(); Observable<Data> getDataFromServer(); } 回答1: I'd suggest using a Single as it is more accurate representation of the data flow: you make a request to the server and the you get either one emission of data OR an error: Single: onSubscribe (onSuccess | onError)? For an Observable you could theoretically get several

Implementing Retrofit2 service interface

由 ￣綄美尐妖づ 提交于 2019-12-04 15:28:13
Imagine the following scenario. I am using Retrofit as my API client and I am going to use a caching mechanism to persist some responses locally in let's say SQLite database, so some of the data is obtained only once. It seems like a perfect case to create a custom implementation for the following interface which is going to fetch the data from local database when network is not available. public interface CommentsService { @GET("posts/{postId}/comments") Call<List<Comment>> getCommentsOfPost(@Path("postId") int id); } The problem is that all service methods in retrofit2 should be wrapped in a

Realm and Retrofit2: sending auto-managed objects

由 本小妞迷上赌 提交于 2019-12-04 14:03:15
When using Realm and Retrofit2 for sending auto-managed RealmObjects to our server, Retrofit2 (using Gson) only sends the ints in the RealmObject. It completely ignores the Strings and other fields, and does not put these in the json. No errors are logged. If I however, disconnect the RealmObject from Realm: realm.copyFromRealm(myRealmObject) then it does send all fields. What could be the problem? Is there a proper solution? Before we dive in In one of my posts here on Stackoverflow, I have explained what's happening when using Gson and Realm together (Retrofit is just using Gson as a data
