An Android app that captures and displaysaccelerometer data on a professionally looking gauge and uploadsthe data to PubNub where it can be viewed on a web page.This app is used as a coding example for Android developers onhow to capture and display accelerometer data on a professionallylooking gauge in real-time.Data is also uploaded to PubNub where it can also be viewed on aweb page in almost real-time.The gauge contains a button that lets you cycle through 4modes:* Speed* Current distance* Total distance* DemoIn Speed mode, speed is shown when you move the device. Shakingthe device faster will result in a larger value beingdisplayed.In Current Distance mode, the app accumulates distance from thetime the app starts and any motion is detected. Distance isdisplayed on the 7 segment display as a value and also shown on thecolored bar segments.In Total Distance mode, the app displays the total distanceaccumulated since the app first started. By "first started", thismeans that the very first time you started the app after installingit. If you exit the app and start it again, that would be thesecond time. Total Distance is shown only on the 7 segmentdisplay.In Demo mode, the accelerometer data is ignored and fake speedvalues are incremented from zero till 10 and then back down to zeroand then repeats.After installing the app, you can also see the data on a webpage by visiting:http://niketestapp.github.io/Accel/index.htmlThe gauge also displays a small connection icon. When it is red,it means that no data is being uploaded to PubNub. This could bebecause the device's wifi is turned off, or possibly becausePubNub's servers are not available. When data is successfully sent,the icon will be green.If multiple devices run the app simultaneously, the gauge dataon the web page will update for each device. This is because PubNubforwards the data to whatever clients subscribe to the data. In areal application, you would probably not want multiple devicesupdating a single gauge at the same time. The purpose here howeveris simply to demonstrate how data can be easily transmitted from adevice to a web page in near real-time.The app only forwards 5 data points per second to PubNub.Source code available at:https://github.com/JohannBlake/Accel

This is a demo app for Android developers.This widget is a virtual keyboard that lets you enterCanadianpostal codes. The keyboard does not implement any AndroidAPIs thatreplace it's own virtual keyboard. Instead, it's a popupview thatis implemented as a library component that you attach toEditTextcontrols. When the user taps on an EditText to enter data,thevirtual keyboard is displayed. Any characters entered inthekeyboard are not entered into the EditText until the Save buttononthe keyboard has been pressed. A textview above the keyboardkeysshows the postal code being entered. Logic is applied tothekeyboard so that the user can only enter a valid postalcode,meaning that the keys alternate between letters and numbers astheyare typed in and only valid characters and numbers aredisplayed onthe keybord. There are some minor postal code rules aswell thatenforce the validation.The keyboard resizes to the width of the parent view that itispart of. A demo app is included that shows how to implementthekeyboard.Source code available at:https://github.com/JohannBlake/CanadianPostalCodeKeyboard
