these are only a few of the errors there are a million more

Answer 1

You should not add the appcompat library jar only. What you need to do is "import" the library as a full project along with its resources so it is another project in eclipse.

After that you add it to your current project as a reference.

This error is happening because it can not find resources. Resources are not bundled with the jar file

Answer 2

The errors here maybe due to one of the following reasons :

1. You are using appcompat-v7 library in your project and you forgot to open this library by double clicking on it in eclipse project

2. You have not imported the library and just copied the jar file into the libs folder of your project directory.

Make sure, you check both of the above issues and let me know if I can help you further..
