android - Where to place SlidingTabLayout.java and SlidingTabStrip.java files in project? -

-

i'm new android studio , i'm following tutorial implements sliding tab layout application. tutorial says put slidingtablayout.java , slidingtabstrip.java in our project, doesn't where. now, put declared them 2 classes , put them under java folder. (...app\src\androidtest\java). however, when try include slidingtablayout object in xml file, says "the following classes not be: found:com.android4devs.slidingtab.slidingtablayout", means must have put 2 files in wrong place. used these files before , know put them?

thank you

the error says could not found slidingtablayout class. means have tell correctly slidingtablayout file placed.

in xml change com.android4devs.slidingtab package name. can find package name in slidingtablayout.java or in manifest file.
