Cannot resolve import com.google.api.client.json.gson.GsonFactory

Question

Am trying to use the GsonFactory class in my app:

StudentApi.Builder builder = new StudentApi.Builder(AndroidHttp.newCompatibleTransport(), new GsonFactory(), null);

but it says cannot resolve symbol 'GsonFactory'

I have the import in my class

import com.google.api.client.json.gson.GsonFactory;

but gson couldn't be resolved so I tried Alt-Enter - Find jar on web but the library couldn't be found.

I have this in my build.gradle dependencies:

dependencies {
   ...
   compile 'com.google.code.gson:gson:2.3'
   compile 'com.google.api-client:google-api-client-android:1.19.0'
}

I can confirm that this class does exist.

You can also use JacksonFactory if possible. #17232222 – Booklet

Answer 1

You need to use this library:

compile 'com.google.http-client:google-http-client-gson:1.19.0'

You can also use JacksonFactory() in lieu of GsonFactory for those API builders if there is some trouble with the dependency. – Skindeep

One more comment: For some reason if using the maven dependency doesn't download the Gson library -- you can just include the library manually. central.maven.org/maven2/com/google/api-client/… – Skindeep

Answer 2

GsonFactory is from the older version.

Now, you should use JacksonFactory.getDefaultInstance() instead.

Import it like this import com.google.api.client.json.jackson2.JacksonFactory;

Answer 3

As of 2022, GsonFactory is back and JacksonFactory is deprecated. Replace JacksonFactory with GsonFactory.getDefaultInstance().

In Gradle: use

implementation 'com.google.http-client:google-http-client-gson:1.41.0'

Answer 4

In your gradle.build you need to add:

compile ('com.google.http-client:google-http-client-gson:1.19.0') {
    exclude module: 'httpclient'
}

after

compile('com.google.http-client:google-http-client-android:1.19.0') {
    exclude(group: 'com.google.android', module: 'android')
}

After doing so, you will be able to use:

com.google.api.client.json.gson.GsonFactory()
