Java Android Studio Interface Builder not working - java

Here is a gyazo because I don't know what's going on.
Basically it won't show up on the iphone, I'm currently watching a tutorial on YT and it worked for him. Any help appreciated!
One more thing is that the Hello world that's supposed to appear when you start the application won't show up either. Is there a setting or something?

Working CandidatesView code on Android Studio?

I tried everything before comin' here, I swear.
But there's no way I'm gonna make this thing work without help.
Does anybody have any CandidatesView class that's actually working?
I couldn't find anything about CandidatesView in android studio website.
I created everything else in the keyboard, but this I can't manage to.
Or does anybody have some example keyboard working?

google mobile ads - using libgdx and Android studio

Ive got my whole game together, using libgdx, working in android studio, and now I'm in the process of putting ads into it. I've done the tutorial here but it doesnt work when youre using libgdx(I cant just follow the steps).
OK, so I managed to get a banner ad to display.
What I did was follow this spanish tutorial, with its accompanying video, but wherever you recognise pieces from the official tutorial i linked in my original question, use the official snippets. basically the part from the spanish/video tutorial that is needed is putting the game into a FragmentActiviy and making a layout file.

How to turn java game code into an android application to play on a phone

Heyyy,
I was recommended this site by a friend who does Computer Science and he said it was the place to go to.
I have the following code for a 'Java' breakout (brickbreaker) game:
http://pastebin.com/fN8WBKpW
A group I am working in needs this code to run as an application on an android device so we can do surveys on it for our work project.
I know little about 'Java code' but one of the guys in our group has android studio + eclipse and has run it on his computer using one of the programs. He doesn't know how to get this code to be an application that he can transfer on to his phone.
If anyone can help us it would be much appreciated.
thankyouuu

Android operates slightly differently than Pure Java. If you want your application to work natively on android, you are going to have to use android specific libraries and classes.

Hello World program for Google Glass - Step by Step

I started reading stuff on Google Glass development one week ago, including this. However, I still could not find a tutorial to develop a "complete hello world program". What I meant by "complete" is; where to get the API, how to set up the API, how to write the hello world UI, how to write the code for the UI, how to install the emulator/simulator and test it. For an example, if you take a Java / Android / C++ / C# book, the first chapter is a hello world program, the "complete note" which explains how to develop it, step by step, making sure the new user is not in a mess. I went through the developer guide, and it is not what I am looking for.
Since I couldn't find anything, what I did is wrote the HTTP code in here, in the given small text box.
But I saw some people have developed code and tested it, so I would like to have "step-by-step guidance for writing Hello world for Google Glass". I am sure it will benefit a lot of new comers as well.
Please note that my favorite language is Java and Android, I do not have a Google Glass and I am not a registered "glass explorer" (as they have asked here) if it matters.
Please provide me step by step instructions / Link to step by step instructions for writing Hello world for Google Glass, because even after a one week of reading, I am totally empty handed, giving so much stress to my student life.
You say that your favorite language is Java and Android so I'm not sure if you are looking for a mirror-api solution or GDK solution. If you want a GDK solution I've created a hello world application and it can be downloaded here: https://github.com/DasCody/Hello-Glass
From the sounds of it you're looking for a GDK solution.
Start with the Android SDK here: http://developer.android.com/guide/index.html
Then move onto the Glass GDK here: https://developers.google.com/glass/develop/gdk/
You can then find a step by step GDK "Hello World" article here: http://www.straza.co.uk/latest/google-glass-gdk-tutorial
