There are a wide range of ways to deal with Android application development. In this series, be that as it may, we’ll be focusing just on the native approach because native applications offer superior performance, keep running with basic overhead, and are fit for making the best utilization of the Android operating system abilities.

Native Android applications are created utilizing the Java programming language, and, on devices running Android 5.0 or higher, make utilization of an managed runtime called Android Runtime (ART) as a matter of course. To make such applications, most developers use Android Studio, the official Android IDE created by Google. Android Studio is free and keeps running on Windows, OS X, and most Linux distributions.

Android Studio 1.5.1, the present stable release, has a large number of features to improve all parts of Android application development, for example, an incredible code editor, visual format and topic editors, vector and picture resource studios, and more. Android Studio 2.0, which is still just accessible as a preview release, has further developed features like instant run and a GPU profiler to additionally enhance the application development experience.

Android Studio additionally comes with a  realistic emulator you can utilize in the event that you don’t claim an Android device. Because system images for it are freely accessible, you can download and run any version of Android on it.

Challenges Android App Developers Face

Building up an Android application that runs well on one particular Android phone or tablet is simple.

While making the layout is as yet a fairly time consuming process, managing distinctive picture sizes has turned out to be simpler thanks to Vector Asset Studio.

Handling Hardware Sensor Availability

Just a few high end devices have all the hardware sensors the Android SDK supports. Consequently, developers are required to compose applications that can decide the hardware capacities of a device at runtime, and reduce gracefully if conceivable.

The Android SDK (Software Development Kit) has a Sensor Framework to improve this undertaking. On the other hand, developers can keep users from installing applications on devices missing the required hardware utilizing Google Play filters.

Recent Trends
