I have recently downloaded Android Studio, I thought it has more features than eclipse.
I created a new project, with a log in activity, but it seems there is an error with the activity :![enter image description here][1]
**Error:(78, 31) error: cannot find symbol class Builder Error:Execution failed for task ':app:compileDebugJava'. > Compilation failed; see the compiler error output for details.** import com.google.android.gms.plus.PlusClient; // This is the helper object that connects to Google Play Services. private PlusClient mPlusClient; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // Initialize the PlusClient connection. // Scopes indicate the information about the user your application will be able to access. mPlusClient = new PlusClient.Builder(this, this, this).setScopes(Scopes.PLUS_LOGIN, Scopes.PLUS_ME).build(); }
