failed to crunch file

Failed to crunch file means studio can't process the file as the file path has reached the max file path length of the operating system.  for windows

->Crude way  to solve it is move the project to some folder in the root of your drive, so in this case.

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

allprojects {  

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

...

}
