“is package not installed?” exception for project have different build variants [duplicate]
问题 This question already has answers here : RuntimeException: Unable to instantiate application (12 answers) Closed 2 years ago . 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? 06-15 10:58:19.104
