Jumping right in, let’s create a Glass GDK project from scratch: Create New Android Project Configure GDK Imports Code qwe To create a new project…See our Part 1 of the tutorial. Make sure to configure the Glass GDK Sneak Peek Manually if it didn’t get configured by Android Studio or Eclipse on set up. As it turns out, even if you create a project setting GDK as the Compile for API, it doesn’t get created as such. You must double check in your build.gradle file (CAREFUL, there are 2 such files. You need to modify your inner most gradle file) and make sure it looks something like this: And you… Read More

Before jumping into Glass dev, let’s understand how to create a Hello World project in Android Studio (AS) and run it on our device. Create New Project Get to know the guts Add Imports Add Code Tweak guts Run on Device Create New Project When you select New Project from the File Menu, you get this Wizard screen: Fill in the Application Name in a natural language and the Module Name without spaces.

Click Next and in the next screen just leave everything as is (the launch icon selector screen).… Read More

My First Android App Android is based on Java much like iOS is based on ObjectiveC. If you are coming from an iOS background, itll be a bit jarring at first. Even though ObjC “comes from” C, C formats are a bit different. So I thought Id start with that first. ObjC: [myObject methodForDoingThis:someParameter]; is a method call which refers to this declared method: -(void)methodForDoingThis: (id)someParameter{ //1. Take the passed in parameter //2. Do something to with that parameter value //3. Call some other method… //4. Or if this were a method that returned an object instead of void //4. Return a new object value } C: myObject.methodForDoingThis(someParameter); is… Read More

Continue ReadingDevelop apps for Google Glass – Part 3 – Setting up!
If you have experience in Android (Java) development, this will be even easier. What you’ll need: Google Glass – to test your apps on Eclipse or Android Studio for coding Android SDK 15 & Glass Development Kit Sneak Peek (GDK) Configure adb Glass Well you either borrow a pair or get your own, but you will need Google Glass to test your apps. The reason being that there is no Glass emulator as there is for Android as of yet. Eclipse or Android Studio Eclipse is the most widely known IDE for Android programming but its worth getting to know Android Studio, the new IDE for developing on Android &… Read More

Feedback system Responsiveness Do one thing right Socialize & Gamify A few clicks Website match Analytics Off-line Customize user experience It’s a mobile device Every app needs to provide the user with a direct connection to the company’s customer service department Above all an app must be responsive and quick. The best app in the world is useless if it takes too long to open. Great apps do one thing and do it right! If you try to juggle too much functionality into one app, the user gets overwhelmed. The best way nowadays to keep users interested is to Gamify or Socialize. Gamify means give your users that carrot they… Read More
Continue ReadingPresence3:NSThread & NSOperation
Im looking through Presence3, understand the LetsMakeAThread project, its pretty straight forward, detachNewThread creates a separate thread and performSelectorOnMainThread returns you to the MT, but in ThreadedFlickrTableView, whats the deal? beginLoadingFlickrData calls a new invocation operation, which loads synchronousLoadFlickrData: which gets the data from Flickr and returns to MT via didFinishLoadingFlickrDataWithResults: which in turn creates the arrays from the FlickrData. Then cachedImageForURL gets called from the cellForRowAtIndexPath? And so that same method calls the ImageLoadingOperation which then returns to the main thread via didFinishLoadingImageWithResult:? Is this chronology correct? The MT gets separated or stopped 2x in this app? Once in beginLoadingFlickrData and then in cachedImageForURL? The difference being that in… Read More
Continue ReadingStanford Assignment 3 HelloPoly: 1 Control/Multiple Actions
I should have known this from my experience in Flash! The solution to why it only draws the first polygon is that the same buttons, Increase and Decrease, required multiple, in this case 2, actions, not just one. Basically you need to define another method, inside the polygonview, which calls setNeedsDispaly. And hook up the same buttons in the nib file to that method.
