Look Counter app and more!

Hi there,

It’s been a long time since I talked about my app’s release, but finally this day came! Today, I want to present you Look Counter – a simple app for counting how many times a day you have turned on and unlocked your phone (or tablet). It counts this in background and displays the latest numbers on the main view. You, as a user, can delete this data at any moment of time (Clear all Data option, with a quick Undo if you change your mind).

I’ve put an About view, if somebody is confused with the minimalist design and doesn’t follow what those numbers in circles mean, or maybe, wants to contact me right away, and say that counting doesn’t work for him at all! 😛

Anyway, the source code is on GitHub, so you can check what’s inside and grab tasty pieces, as well as point me at my mistakes 😉

Tutorial: How to use a Handler?

Hello,

Today I will show you how to benefit from Handlers in Android 🙂

First of all, Handlers aren’t some new concept, they were there long ago. How long? Well, from API level 1. Still, I always felt Android developers don’t use them enough, me included.

When I’ve discover the brilliance of Handlers, I was surprised how handy they are and how easy is to use them.

So, what does a Handler do? A few things, really.

Tutorial: Parse JSON with LoganSquare

Hi, guys!

Today I want to present you a new JSON-parsing library – LoganSquare, written by BlueLine Labs. It is told to be the fasted available and quite easy to use, so I couldn’t miss it 😉 Below you will find an example Android project, which serializes and parses some objects.

Also, I have run Logan’s Benchmark project myself and indeed, the results are good. Not as good, as on their GitHub’s page, but still. Just to make everything clear, I have used Nexus 5 running Android 6.0.1 (ART).

As you can see, LoganSquare wins in every category. Lets check how we can use it in our project, shall we?

Tutorial: PIN input view in Android

Hi, guys!

Today’s post will be about PIN-like view in Android. I’m sure that many Android developers would like to have it by default, me included. And so I wanted to show you how I handled the problem caused by lack of such view. But first, how should it look like? Well, it should like an input field where every character has it’s own box and while typing, characters should automatically populate those boxes. Sounds pretty easy, isn’t it? But later, when you think about all of the aspects, you will realize it’s not that simple at all…

First, I wanted to mention that this particular example is for text passwords (or text pin). The code for just numerical PIN view would be much easier. But it wasn’t the case with the app I was writing and I definitely needed the default keyboard. Because I could change my soft keyboard from text to numerical at any point of typing, I couldn’t have a collection of EditTexts because switching from one to another would have changed a keyboard either to text or numerical and I didn’t want that.
