“is package not installed?” exception for project

This question already has an answer here:

RuntimeException: Unable to instantiate application 12 answers

I have a question. When project is run, I rarely get fatal exception. I have two different android applications in the same project for different build variants. But their package name are different. In manifest file, my first application's package name is written. I rarely get fatal exception, when I run my second project.

How can I fix this error?

You should control your architecture, does anywhere else control your build variants or have your project any xml file regarding build-variants as static string.
