Okay, so my programming teacher sent me an app that I should look at and modify. I downloaded the APK file, and turned it into a source code following these instructions: [how to extract code of apk file](https://stackoverflow.com/questions/7888102/how-to-extract-code-of-apk-file).

I have the java (src) files, the resources files, and the XML files. I have the Manifest file too.

I imported them successfully on eclipse, but now it has like 2000 errors.

I really don't know what to do. The apk works fine on my phone.

Why is it doing this?

If anyone needs the apk, I'll upload it.

If someone can be so generous to convert it into a working eclipse workspace for me, I'll be more than grateful.
