While this message is not really something that will affect your web app, people like me tend to see warning messages as annoying and as such will go to great lengths to find a solution that will avoid having this warning message appear in the console.

The sample below indicates an Ext.Label declaration is missing.

To fix this, all you need to do is go to app.js and add this class in the requires field.

You can also add them within your view, controller and other classes if you wish to specifically require them within those scopes. However, the global option is more hassle free.

That’s it! That should clear those warning messages.

Finally, Android users need not despair. Electronic Pages launched its Electropages Android app to deliver real time news to estabished component buying engineers and designers worldwide.

Sure, one can view such news in their website. But considering that majority of us nowadays use smartphone, it is imperative that users get updated anytime, anywhere.

Apps are one way for users to check up on news and updates and ElectroPages finally gave Android users the convenience to check up on real time news regarding products that benefit designers, engineers and many others interested to learn about specific topics.

Look at Electronics News as a press release platform that whenever such new product details emerge, those running the app will then be able to read up on the news itself.

This app brings buyers and sellers together within a dedicated professional forum that delivers the right information to the right person at exactly the right time.

When it comes to technology, being updated is a necessity. Using the app, users can gain direct access to exclusive content from premier providers like Mouser, Farnell element-14, RS Components and Digi-Key along with options to Buy Direct.

Not only that, there are also videos with a catalog of hundreds of educational videos designed for engineers and designers. From an information standpoint, this is not just a platform for news but also contains a plethora of resources to helping electronics engineers and designers source new electronics products.

The good thing about this app is that it is free so go give it a download.

Information is critical in the technology industry. I am glad ElectroPages did not leave Android users behind iOS. The app is pretty easy to navigate. Everything is self explanatory.

I am sure you will not have a hard time using the app. In case you are interested, you can also get the iOS version of this Electropages iPhone app.

This one is fairly easy. The common cause for this is when you have a Dialog popup that shows itself whenever the user quits the app.

This happens when you call finish() to close the Activity without closing the Dialog object.

Make sure you call dismiss() first before finish().
