i am using Android Studio 3.2v and i am getting this error when i run my main_activity

Question

Execution failed for task ':app:transformClassesWithInstantRunForDebug

Answer 1

NoClassDefinationFound error

Means that it couldn't find class com/google/protobuf/message . Perhaps you missed one of the dependencies in the Build.gradle which is related to com/google/protobuf/message . You can try to add this dependency however:

https://mvnrepository.com/artifact/com.google.protobuf/protobuf-java/2.0.3

Which seems to be related.

• Also, use implementation instead of compile .
• Try disabling multidex or, update it to the latest version ( 1.0.3 ).
