Why is Android studio having problems with capitalized package names?

Question

I have an app that started in eclipse. The package name starts with a capital, and it always compiled and installed correctly. Now that I have moved the project into android

Answer 1

In Android Studio rename the package name and in build.gradle leave old applicationId. Although your project's package name matches the application ID by default, you can change it. You should never change the application ID. More: https://developer.android.com/studio/build/application-id.html#change_the.package_name
