Android Studio: ClassNotFoundException

Question

i was busy with my app for over a week, when suddenly:

11-12 07:59:17.860    1653-1653/nl.test.myapp E/AndroidRuntime﹕ FATAL EXCEPTION: main
java.lang.Runtim         


        

Answer 1

You can check Multidex mechanism. The reason may be method numbers overflow.

1. Add MultiDex.install(this); to your Application:

   @Override
   protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        MultiDex.install(this);
   }
   

2. and add

   afterEvaluate {
      tasks.matching {
          it.name.startsWith('dex')
      }.each { dx ->
          if (dx.additionalParameters == null) {
              dx.additionalParameters = []
          }
          dx.additionalParameters += '--multi-dex' // enable multidex
      }
   }
   

to your app module's gradle.build
