Android applications development companies are busier than ever, and it’s very likely that the current demand will be considered nothing compared to what’s about tải app android apk

to happen. According to market research statistics, one in three mobile phones are now shipped with Google’s OS, whose smart phone market share is still going up. Let’s just take a peek under the hood and see what all the fuss is about.

Before diving into the geek end of the pool, it’s important to focus on one very important aspect. Android is an open source project with a software stack that includes the OS and key applications, along with middleware. The operating system is a multi-user Linux system and the applications are written in Java.

As should be obvious from all this, the keyword here is open source. The use of Linux and Java makes it very attractive to the vast coalition of open source developers and fuels more innovation and future development. Needless to say, this is one of the key aspects of Google’s smart phone OS and app strategy that sets it apart from Apple, Microsoft and Nokia’s smart phone offerings.

Now let’s get down to how someone could actually get started with Android applications development. This someone would need to download the Android SDK (software development kit) which includes all the APIs and tools required for getting started. The tools included can be accessed using an Eclipse plug-in known as ADT.

The process is simple and has a clearly defined series of steps. Start by downloading the SDK and installing Eclipse with the ADT plug-in. Then setup virtual Android devices or connect the real hardware on which the application is to be installed. Then create the project, build and run the app, and debug it using the debugging and logging tools in the SDK.

The testing and instrumentation framework is provided for app testing. The app ends up as a single. Apk file which is considered as a distinct user by the Linux OS and assigned a unique user ID. Each app gets its own virtual machine (VM) which helps it run separately from other apps, and its processes get shut down when not required. Also to be noted that each app is actually a combination of components like content providers, broadcast receivers, activities and services that can be run separately.
