Google Drive Android API tutorial issue -

following this tutorial, pasted code main activity:

@override public void onconnectionfailed(connectionresult connectionresult) {     if (connectionresult.hasresolution()) {         try {             connectionresult.startresolutionforresult(this, resolve_connection_request_code);         } catch (intentsender.sendintentexception e) {             // unable resolve, message user appropriately         }     } else {         googleplayservicesutil.geterrordialog(connectionresult.geterrorcode(), this, 0).show();     } } 

i end having import buncha libraries, still can't fix error:

resolve_connection_request_code cannot resolved variable 

any ideas??? can't figure out library contains constant...

turns out when tutorial specifies start android project, mean google drive android project, has different imports , class definitions, aren't made clear tutorial. give starter code google drive android project, mislabeled "android quickstart" assumed no different other android project.

here's link goes: google drive android quickstart, , tutorial makes alot more sense if use code reference.

if curious fix original issue is, constant should request_code_resolution, again, there alot more changes use google drive android quickstart
