No class found exception com.squareup.okhttp.logging.HttpLoggingInterceptor

Question

Even after adding the dependencies and importing the class I am getting java.lang.NoClassDefFoundError: com.squareup.okhttp.logging.HttpLoggingInterceptor.

Can anyone please help?

Answer 1

Could be a compatibility problem with retrofit.

Try with :

implementation 'com.squareup.okhttp:logging-interceptor:2.5.0'

Answer 2

In my case, I found that the versions of the okhttp3 and okhttp3:logging-interceptor dependencies needed to exactly match. So for example:

...
compile 'com.squareup.retrofit2:converter-gson:2.1.0'
compile 'com.squareup.okhttp3:okhttp:3.4.1'
compile 'com.squareup.okhttp3:logging-interceptor:3.4.1'
...
