java - I can't extend Form -

-

i started using android studio recently, , i'm following this guide can't seen extend form, android studio highlights form in red , gives me option alt+enter. once alt+enter import form, show 

import java.text.normalizer;

but guide show 

import com.google.devtools.simple.runtime.components.android.form;

"alt-enter" give options available on local build. tutorial gives assets , if not placed in project, not work.

you should able manually add import:

import com.google.devtools.simple.runtime.components.android.form;

if fails, assume did not add ".jar" file in tutorial. there several ways add jars (like put in "libs" folder). search , can select works best , should fix problem.

once it's imported project, should see import option. if don't manually entering works, maybe restart android studio if happens. either way, should have build @ point, , that's matters.
