Android Question

Why the unsigned application does not find the Application class?

The application that I am developing is crashing in some mobiles when it is not signed. When I sign the application, it works perfectly on the same devices that previously made the application crashes.

The error is:

Process: com.my.application, PID: 10293 java.lang.RuntimeException: Unable to instantiate application com.my.application.di.base.App: java.lang.ClassNotFoundException: Didn't find class "com.my.application.di.base.App" on path: DexPathList[[zip file "/data/app/com.my.application-1/base.apk"],nativeLibraryDirectories=[/data/app/com.my.application-1/lib/arm, /vendor/lib, /system/lib]]

I'm not obfuscating my code, nor use instant run. I'm using multidex.

Answer Source

For creating debug apk create it from Build>Build APK. The issue you are facing is because of instant run.
