Fb vs G+ android sdk

Recently I had an opportunity to implement facebook and google plus login into android application. So i decided to write a small comparison of those two (fb v4.3, google services v4.3.23)

Google plus

  • server side setup required (create new app)
  • adding generated key into android manifest
  • implementation consists of a few methods, activity implements ConnectionCallbacks and OnConnectionFailedListener

Facebook

  • server side setup required (create new app)
  • adding generated key into android manifest, and declaration of one activity
  • sdk is not compatible with eclipse (there can be found an easy workaround on stackoverflow)
  • xml customization of fb button can be done only by overwriting styles in Fb SDK (which is not a recommended solution)
  • implementation consists of only a few lines of code (initialization, button listener, onActivityResult)
  • if user enters invalid fingerprint of debug/release key, the error shows value of your key (very helpful)

Conclusion

Apart from two fb drawbacks I have to admit their documentation is really helpful. Both tutorials have the initialization process split into few short articles but I was stuck for about a half day with g+ implementation. I wasn't able to revoke user's already granted access. Finally I found out (on stackoverflow) that I missed one line which was not in main documentation. 

       
/* Client used to interact with Google APIs. */
mGoogleApiClient = new GoogleApiClient.Builder(this)
    .addConnectionCallbacks(this)
    .addOnConnectionFailedListener(this)
     //use 
    .addApi(Plus.API, Plus.PlusOptions.builder().build())
     //instead of 
     //addApi(Plus.API)
    .addScope(Scopes.PLUS_LOGIN)
    .addScope(Scopes.PLUS_ME)
    .build();

Counting dice and train wagons using computer vision

Computer vision exercises with preprocessing Before the next project I decided to do some computer vision exercises. Each example is based on a simple logic image preprocessing. No data structure or learning is required. Dice I got this idea while browsing the net. I was curious about how hard can it be to write such a script. I'll describe the algorithm in steps. movement detection : Comparing few frames with thresholds gives us the information, whether something is moving in the frame. Adding some small time frame after the movement stops gives us more precise information. remove background : Thresholding gray frame removes the background and gives us binary image with objects cropping the objects : Using contours to detect object and then separate them by cropping. detecting dots : Inverting the image we get objects that can be again simply detected using contours. filtering dots : If dice is visible also from the side therefore dots from that side can be recogn

Play table

Using proximity sensors for playing midi tones combined with LED visualization Description The aim of this project was to create a table sized device with multiple proximity sensors that can play midi tones. Each sensor had a few LEDs to show hand distance above the table. This table could be used by one or more persons at once. Hardware setup First I created a prototype from a cardboard to test sensors and some logic behind. Than I ordered a customized plottered sticker with a design which was painted with bare conductive paint. Afterwards I drilled some holes and connected the touchboard with 7 arduino Nanos. Each arduino was connected to 13 LEDs diodes. At the end I added two potentiometers. One for controlling volume and one for changing notes setup. Programming Programming consists of two parts. Master(touchboard) program that reads values from proximity sensors and sends messages to slaves(arduinos). Second program for slaves that reads messages from m

Skate tricks recognition using gyroscope

Image
In this article we're going to describe how to recognize a skateboard trick using a gyroscope. This sensor is already present in most of the smartphones but in case you are not familiar with it, here is a description . Before we begin, small disclaimer. This project was originally as a part of hackathon that was used with Slido and the purpose was to confirm that it's possible to recognize a trick using a gyroscope. For the sake of simplicity of this project we're not considering skater's stance on a board and we're only trying to recognize 2 simple tricks. So, let's begin by splitting the problem into several smaller ones. We need to record the trick, store it, describe it, understand it, and then of course recognize it. Recording the trick Let's start with the trick recording. To have a precise data we need to have a device with a gyroscope that is attached directly to a skateboard. We need to place it on the bottom of the board, otherwise it might interfe
