This cannot resolve symbol

I think that many developers are troubled by cannot resolve symbol, but this time I made a jar with eclipse and added it to Android Studio and got hooked.

I hope it helps someone as one of the solutions. (Although it was my simple mistake after all)

Cause

The eclipse package became the default package

solution

I made a package properly and moved the class files contained in the default package. that's all.
