Android Studio: NoClassDefFoundError on all classes of the app module

Initially I was using
OkHttpClient
for network calls. The app used to crash while initializing the AsyncTask with the same
NoClassDefFoundError
. Search for a solution but couldn't find a suitable one. Then I observed that the app crashes during all the network calls with the same error. Then I replaced the
AsyncTask
with Volley
JsonArrayRequest
. The app still crashes while initializing the
JsonArrayRequest
with the same error
NoClassDefFOundError
.

Can someone help me in resolving this issue?

UPDATE: Later I found that this was not the issue with the
AsyncTask
or
JsonArrayRequest
but I was thrown NoClassDefFoundError for all the classes in my app library except for the activities. Some how in some mobiles, class definitions for the classes in the app module were not found. Observed in mobiles like MI 3, MI 4, Google Nexus.

Answer

Thanks for your answers. The original reason for the NoClassDefFoundError is I forgot to enable MultiDex by setting

 multiDexEnabled true

in the gradle file as suggested here.
