Collecting All Cheat Sheets

Mobiletuts+ will be covering all major mobile platforms – iPhone, Windows, Android and Blackberry. Today we’ll be taking a look at Android development: explaining why people have choosen to work with Android and providing an overview of the Eclipse IDE and its Java, DDMS and debugging perspectives. Finally, you’ll learn how to get started making your first Android app!

Developing services with Android Gingerbread and Eclipse

This tutorial describes how to create and consume Android services. It is based on Eclipse 3.6, Java 1.6 and Android 4.0 (Ice Cream Sandwich).

An Activity is an application component that provides a screen with which users can interact in order to do something, such as dial the phone, take a photo, send an email, or view a map. Each activity is given a window in which to draw its user interface. The window typically fills the screen, but may be smaller than the screen and float on top of other windows.

In this article we shall try to listen to the phone state when contacts are calling us.

First of all we need to set our Manifest file to listen to the Phone State, to do that we need to edit our it.

My previous article explains how to use the TelephonyManager. One of the important functionality of TelephonyManager is listening to different phone state events. The method listen(PhoneStateListener listener, int events) is used to add a phone state listener. The first parameter is the PhoneStateListener class and the second parameter is the int value contains various phone state to listen. We can listen for following events:

Everyone uses different kinds of mobile devices built using different mobile operating systems.The two popular mobile Operating system are iOS and Android since these two contribute majority of market share.

Not just two,windows phone 7,blackberry OS are also popular in mobile space.So if you are a developer who want to build applications for mobile ? the very first obvious question that rise in your mind would be “which platform to choose ?”

Developers often choose a platform which reaches to more people or devices hence they develop applications in one common language and deploy them to all the popular platforms at once-This is called as cross platform mobile development.

If you are programmer or actually if you at least have some basic coding skills, you’ll find this article useful. For example just look at this page source – without highlighting that whole code is just a bunch of plain black text and it is really hard to find specific things if everything looks the same. Thankfully there are many highlighting scripts available, for example Notepad++ also supports and highlights different code snippets. These code syntax highlighters actually are doing mainly the same thing, but with more options, big coding language support, better integration – really in our days you just need to choose one – there are too many tools available anyway.

Środowisko programistyczne Gambas 2 pozwala na zapoznanie się z programowaniem w języku ? No właśnie – jest to swego rodzaju visual basic dla linuksa. Wszyscy którzy już zetknęli się z visual basic – poczują się w Gambas 2 jak „U siebie w domu”. Gwoli sprawiedliwości jedno trzeba przyznać, że nie wszystko jest tak samo jak w visual basic to jednak nawet poczatkujący programista nie powinien mieć żadnego problemu z opanowaniem tego przyjaznego środowiska programistycznego.

If you’re a designer or developer, you’ve probably heard about Git, and you might know that it has become immensely popular, especially among the open source community. Though it may seem cryptic at first, this version control system could change the way you work with text, whether you’re writing code, or a novel.

This article covers why version control is important, how to install the Git version control system, and how to get started with your first repository. Once you start using Git, you’ll want to throw everything into it, from full-blown apps to blog post drafts, because it’s so easy and versatile.

There’s a lot to get excited about in mobile application development today. With increasingly sophisticated hardware, tablet PCs and a variety of software platforms (Symbian OS, iOS, WebOS, Windows Phone 7…), the landscape for mobile developers is full of opportunities — and a little complex as well.

So much choice can be overwhelming when you just want to get started building mobile applications. Which platform should you choose? What programming language should you learn? What kit do you need for your planned project? In this tutorial, you’ll learn how to start writing applications for Android, the open-source mobile operating system popularized by Google.

Thanks to expertly crafted libraries such as jQuery and MooTools, JavaScript has become a foundation of Front-End Development. However, it’s extremely important that we note the higher level concepts utilized in these wonderful libraries. Why is that? As web developers, we must equally balance learning the current programming trends with attempts to push the boundaries of those trends. Without this balance, no innovation will occur in web development. So let’s take a moment to appreciate the fundamentals of JavaScript Object Oriented Programming, which include classes, inheritance, and scope.

You’ve got countless bits of HTML5, CSS3, JavaScript, and PHP rolling around in your head and on your hard drive that you are forced to try to recall each time you start a project. It’s time to get organized.

This post will briefly point you to 27 great utilities that not only help you store your favorite snippets both locally and in the cloud, but also make sharing with others a breeze. Enjoy!
