Android widget rendering error

How can I fix it? I created the project and bam, instant error without touching any code. Any fixing method is appreciated. I have tried sync, clean code, clean cache. None of these methods work.

Android studio. Rendering problems. The following classes could not be found

When I try to look at my layout file I take this error:
Error
The following classes could not be found: - android.support.v7.widget.RecyclerView
I know there are many same questions in stackoverflow, but I didn't find solution for my problem. Full text of error is below. I use buildToolsVersion 23.0.2 and support library - 23.2.0. If I try to see how looks layout file in API version 22 or 23 it works right, but if API version is 21 or less I take this error.
Here is full text of error:

java.io.FileNotFoundException config\security.properties when running from IDEA

When I run my application from IDEA I'm getting the following warning (see below). When running the same code from outside IDEA, this warning does not appear (even though the file isn't really there as well.
Seems like everything is working OK, but still, it's kind of annoying... how can I get rid of it?
(BTW I'm using Tomcat embedded).

From your question it isn't clear which logger is logging this warning (looks like one of the Tomcat's) and neither which version of Tomcat you are using, but you can generally fine tune the log levels in Tomcat. More information here:
http://tomcat.apache.org/tomcat-6.0-doc/logging.html
I wouldn't really advise you to disable warnings however.

Here's my app main entry point class:
public class MainAppEntryPoint implements EntryPoint {
private final ClientGinjector ginjector = GWT.create(ClientGinjector.class);
#Override
public void onModuleLoad() {
// Inject global styles
GWT.<Resources>create(Resources.class).style().ensureInjected();
// This is required for Gwt-Platform proxy's generator
DelayedBindRegistry.bind(ginjector); // Line 10, reference from the stack trace above
ginjector.getPlaceManager().revealCurrentPlace();
}
}

This was solved by doing a project cleanup with Eclipse
