retrofit convertor factory can not access GsonConverterFactory

Question

I have included these dependencies to my project:

compile \'com.squareup.retrofit:retrofit:2.0.0-beta2\'
compile \'com.squareup.retrofit:convert

Answer 1

Try to use same version for retrofit and converter-gson - 2.0.0-beta2. You are using beta2 for retrofit and beta1 for converter.

implementation 'com.squareup.retrofit:retrofit:2.0.0-beta2'
implementation 'com.squareup.retrofit:converter-gson:2.0.0-beta2'

Important note!

Retrofit change its package name since 2.0.0-beta3 version. Now you should use com.squareup.retrofit2. Here is example:

implementation 'com.squareup.retrofit2:retrofit:2.2.0'
implementation 'com.squareup.retrofit2:converter-gson:2.2.0'
