Question

Error:Failed to crunch file C:\\Users\\marschall\\

Answer 1

Failed to crunch file means studio can't process the file. Its too long and it has reached the max file path line of the operating system.

-> Crude way to solve it is move the project to some folder in "C:\".

-> Better way is to change the build directory of the project in the build.gradle file (Project)

allprojects {
    buildDir = "C:/tmp/${rootProject.name}/${project.name}"
    .
    .
}
