kandi X-RAY | gson Summary

gson is a Java library typically used in Utilities, JSON Processing applications. gson has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has high support. You can download it from GitHub, Maven.

Gson is a Java library that can be used to convert Java Objects into their JSON representation. It can also be used to convert a JSON string to an equivalent Java object. Gson can work with arbitrary Java objects including pre-existing objects that you do not have source-code of. There are a few open-source projects that can convert Java objects to JSON. However, most of them require that you place Java annotations in your classes; something that you can not do if you do not have access to the source-code. Most also do not fully support the use of Java Generics. Gson considers both of these as very important design goals.

OK, It took some time, but I've found what was going wrong and how to workaround that.

When Android Studio's emulators running in Windows series OS (checked for 7 & 10) receive json-typed reply from server with retrofit it can with various probability loose 1 or 2 last symbols of the body when it is decoded to string, this symbols contain closing curly brackets and so such body could not be parsed to object by gson converter which results in throwing exception.

The idea of workaround I found is to add an interceptor to retrofit which would check the decoded to string body if its last symbols match those of valid json response and add them if they are missed.

I suspect the Android emulator might be interfering with you here. I’ve seen issues with it misbehaving, particularly on Windows.

https://issuetracker.google.com/issues/119027639

If you'd like to workaround, consider changing your server to use something other than Connection: close to terminate your response body. Perhaps chunked encoding or a content-length header.

I'm not sure what you're using to code, but in order to set it in Android Studio, open the manifest of your project and under the "activity" section, put android:exported="true"(or false if that is what you prefer). I have attached an example.

As I understand your question, this is less to do with retrofit and more with JSON parsing. Because the payload structure is a bit awkward I suggest you consume it in two steps:

step 1. Consume the content success, cache_last_updated and total
step 2. Add the id

ANSWER

Answered 2022-Jan-20 at 05:58

In my case, firebase UI (com.firebaseui:firebase-ui-auth:8.0.0) was using com.google.android.gms:play-services-auth:19.0.0 which I found with the command './gradlew -q app:dependencyInsight --dependency play-services-auth --configuration debugCompileClasspath'

This version of the play services auth was causing the issue for me.

I added a separate

implementation 'com.google.android.gms:play-services-auth:20.0.1'

to my gradle and this issue disappeared.
