Gson library in Android Studio

Question

Can someone give me step by step guide to add the Gson library to an Android project?

I tried the JSON built-in library but that seems to be a bit tedious right now. I saw a couple of examples based on Gson, and that seems really easy.

Add following dependency to build.gradle:

implementation 'com.google.code.gson:gson:2.8.7'

Or download the JAR file from Maven by clicking a release and finding the .jar file.

Replace 2.8.7 with the latest version from Maven.

Visit the GitHub repo for documentation and more.

It didn't owrked immediatley after adding in dependencies and trying to build my app. I had restarted my android studio and tried to rebuild it. It worked :) – Jagadish Dharanikota Mar 11 '17 at 17:14

@JagadishDharanikota I noticed this as well. I think you can fix without restarting by using File -> Sync Project with Gradle Files – okhobb Oct 03 '20 at 01:52

Read Google-gson

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.

Add the following line to your MODULE LEVEL build.gradle configuration:

dependencies {
     implementation 'com.google.code.gson:gson:2.8.8' // Old 2.8.6
}

Use gradle dependencies to get the Gson in your project. Your application build.gradle should look like this-

dependencies {
  implementation 'com.google.code.gson:gson:2.8.2'
}

If you are going to use it with Retrofit library, I suggest you to use Square's gson library as:

implementation 'com.squareup.retrofit2:converter-gson:2.4.0'

Any specific reasons for Squares Gson being better than Googles Gson? – Prasad Pawar Mar 22 '21 at 13:21

Gradle:

dependencies {
   implementation 'com.google.code.gson:gson:2.8.5'
}

Maven:

<dependency>
  <groupId>com.google.code.gson</groupId>
  <artifactId>gson</artifactId>
  <version>2.8.5</version> 
</dependency>

Gson jar downloads are available from Maven Central.

There is no need of adding JAR to your project by yourself, just add dependency in build.gradle (Module lavel). ALSO always try to use the upgraded version, as of now is

dependencies {
  implementation 'com.google.code.gson:gson:2.8.5'
}

As every incremental version has some bugs fixes or up-gradations as mentioned here
