how to create new project by copying from another one?

I created a new project and copied Assets and ProjectSettings folders from another project.
I did not copy Libraries and Temp folders. Of course the name of new project is different.
It works fine on the Unity simulator. But It does not work on Android phone.
When I am doing ‘Build and Run’, it stops with a message ‘Not a file’ like this. No APK file.

Error: Not a file ‘/Users/davidkim/MyNewProject’
UnityEditor.HostView:OnGUI()

Did I miss something? Should I do something more after copying?
Any comments will be very appreciated. Thanks in advance.

This is the list of the project folder…
Folders: Assets, Library, ProjectSettings, Temp
Files: Assembly-CSharp-firstpass-vs.csproj, Assembly-CSharp-firstpass.csproj, Assembly-CSharp-vs.csproj,
Assembly-CSharp.csproj, Myproject-csharp.sin, Myproject.sin, Myproject.userprefs

I think that there are some absolute paths involved and therefore can´t simply copy all your stuff. To solve it I create a unity package containing all my proyect files and then extract it into a new proyect.
