How to Use Android SDK? [A Complete Guide for Beginner]

Android SDK has always been an integral part of all 2.7 million Android apps available on the Google Play Store. However, many beginners or aspiring Android app developers don’t know how to use Android SDK.

If you are sailing in the same boat with such beginners, then do not worry. We have crafted this exclusive blog for you. With this blog, you get to check the key elements and steps to use Android SDK, and some commonly asked questions. So, shall we begin?

What is Android SDK?

The Android SDK consists of software development tools in one installable package that you use to develop Android apps. This software development kit includes an ADB bridge, emulators, and various source code to create the groundwork for an Android app.

The benefit of using SDK is that it provides a smooth flow of the development process, from developing and debugging through to packaging. It is compatible with Windows, macOS, and Linux.

A new SDK is released every time when Google releases a new version of Android. Developers use new SDK whenever they want to develop apps for the upcoming Android version in the market.

After learning about Android SDK, you must be looking for its essential elements. Didn’t you? Rest assured, we have shared all the key elements in the next section. Let’s get going.

Key Elements of Android SDK

  1. Platform Tools

  2. To be specific, these tools are unique for each version of Android. You need to update platform-tools continuously once it is downloaded. Moreover, platform tools are backward-supportive and support old platform versions of Android.

    It comes with various tools that interface with the Android platform and are required for Android development, such as adb fastboot, and systrace. You will also need platform tools if you try to unlock your device bootloader and flash it with a new system image.

    Platform Tools

    • Location: $ANDROID_HOME/platform-tools
    • Main Tool: adb (Helps to manage the state of an emulator or an Android device)
  3. Build Tools

  4. Initially, SDK build tools were clubbed and downloaded with platform-tools until it was not required to update them separately. Later, these were excluded, and now it is necessary for such apps, which require the minimum amount of battery consumption while it is in operation.

    Build Tools

    • Location: $ANDROID_HOME/build-tools/$VERSION/
    • Main Tools: aapt (To generate R.java and unaligned, unsigned APKs), dx (To convert Java bytecode to Dalvik bytecode), and zipalign (To optimize your APKs)
  5. SDK Tools

  6. It consists of debugging tools, libraries, sample source code for creating Java profiles, testing tools and comes with Android Studio. Android SDK Tools have stock Android emulator, hierarchy viewer, SDK manager, and ProGuard.

    SDK Tools

    • Location: $ANDROID_HOME/tools
    • Main Tools: ant scripts (To build your APKs) and ddms (For debugging)
  7. Android Emulator

  8. This tool is an Android virtual device (AVD manager) that helps to simulate Android devices on your computer. Test your Android app on different devices and Android API levels without having the requirement of each physical device. It has all the capabilities of an actual Android device.

    You can perform activities like simulating phone calls, text messages, different network speeds, and hardware sensors, such as rotation, along with accessing Google Play Store.

  9. Android Debug Bridge (ADB)

  10. It is a versatile tool and helps to communicate with a device. Moreover, it has various features that let you install and debug Android applications. With this, you get access to the Unix shell to run multiple commands on a particular device.

    Now, you know the key elements/components of Android SDK, it would be much easier for you to proceed with the downloading process and to know how to use it. Let’s find out how you can install it and start working on your first Android app development project.
