I began completing Homepwner in a version of SDK 3. I recently downloaded SDK 4. I began Chapter 13, and opened the Homepwner project. I tried Building and Running it before I began any new code. There was one error and it said that the “Base SDK was missing”. This is because I worked on the project in SDK 3, and I am now trying to run it in SDK 4. How do I fix this problem? Is there any way I can salvage my work and find a way to convert the project to SDK 4 so it can correctly Run?
P.S. Thanks a lot. I’m a beginner, I apologize if this is a simple fix.
