Android SDK 5.0 API 21 Lollipop Direct Download

Welcome Android Devs!

This page provides you all Android SDK Packages for Android 5.0 Lollipop API 21.
We split them to several parts:
Base Package: Android SDK Tools

Android SDK Tools is the base package and is required to be setup first before anything else. It contains sdkmanager CLI tools that manages other packages.
You must install it as this is required packages.

Essential Packages

They are packages that essentially needed for your daily Android app development.It consists of Compiler,Source,Platform Tools,Build Tools and optioanally System Images.

Some packages must be installed as they are required pcakges,others are recommended as it bring extra benefit and else are optional since not installing them don't affect core compilation.

Extras Packages

They are packages that brings support to extra features and libraries that are not available by default on the main compiler.It consists of Andoid Support Respository, Google Support Library, Play Services, Instant Apps SDK , GAPI debug , and several others.

We recommend you to install several extras as they bring support to target older version of Android and again, bring extra fetures on demand

Emulator and Intel HAXM Package

Emulator will emulates Android OS in your computer by booting the System Images packages.
Intel HAXM accelerates the emulation by taking advantage of hardware acceleration capability on compatible CPUs.

If you wish to test your app on your computer , we recommend you to install Emulator and Intel HAXM and several System Images as your choice.
You don't need to install them if you prefer to test your app directly of a real device instead

NDK Toolkit

NDK and C++ packages contains SDK and toolkit for Android Development that is written in C/C++.The package is necessary if your codebase is completely written in C/C++ OR if you need some parts of the code to be written in C++.So if your code is mainly written in Java/Kotlin, this packages are optional to install.In reald world development, NDK is very often used by the 3rd parties toolkit like C/C++-based game framework that target Android OS.

Documenation for Offline Browsing

Android SDK 5.0 Lollipop API 21 Essential Packages

A Notice for Publishing your Android App on Google Play

Starting from August 2018 , Google made new requirements for the new apps published on their Play Store.
Your apps MUST be configured with targetSdkVersion≥26 aka Android Oreo 8.0 API 26 or higher.
Thus as developer you should aware since this will impact you as app publisher:

  • because if targetSdkVersion set to 26 or higher , you will need Compiler version 26 or higher
  • with this requirements Android Studio v3.2~+ will flag targetSdkVersion<26 as error

In correlation with offline SDK Packages we provide in the table below, we clearly inform you:

  • All packages mentioned in this table are still working,functioning and are NOT YET obsolete.
    It can be used for production purpose just well.
  • The targetSdkVersion≥26 requirement DOES NOT impact Andrioid SDK Tools,NDKs and Extras. Only these essential packages whose API level<26.

You can download, install and use ALL packages listed in this table as long as:

  • if you published your Android apps to market place OTHER than Google Play.
    Other marketplace has different policy regarding targetSdkVersion.
  • if you published your Android apps for personal use, that you just install directly to your phone.
  • if you published your Android apps for internal use in your organization,community etc that the limited users can install directly without marketplace.
  • if your intention is for learning purpose

You MUST download,install and use NEWER packages than listed in this table if:

  • you published your app into Google Play market

THE GOOD Thing is: with newer SDK compiler packages you can still target older version (minSdkVersion) like API 22 (Lollipop) and API 19 (Kitkat).

Put simply:

  • if your main intention is publishing app for Google Play market, please install NEWER essential SDK packages (API Level≥26)
  • Otherwise, go download,install them and use them.

BE CALM :D .We've already provided these pages contains packages with SDK API level≥26:

Contains offline version of Google support libraies artifact so you can use various APIs for Google Play Services,Firebase and Wearables.
Instant App SDK
Contains library for building Android Instant Apps so the user can enjoy the app instantly without installing first
Other Extras

Emulator and Intel HAXM

Emulator emulates the System Images so you can test your app on your computer.If you've downloaded one or more system image(s) you should install Emulator.For even faster emulation and take advantage of virtualization feature in your CPU, you should install Intel HAXM as well.

Checkout:

Android Emulator
Emulates System Images on your computer, so you can debug your app directly on selected Android OS version and arch without actual hardware.
Intel HAXM Accelerator
Bring emulation faster by taking advantage of hardware virtualization feature on supported Intel CPUs.

NDK Toolkit

The NDK Toolkit is a toolset that lets you implement parts of your app in native code, using languages such as C and C++. For certain types of apps, this can help you reuse code libraries written in those languages.

Android NDK Compiler | NDK (Side-By-Side Installation)
Contains set of tools that allows you to use C and C++ code with Android.
CMake
An external build tool that works alongside Gradle to build your native library.
LLDB
The debugger Android Studio uses to debug native code.

Offline Documentation

Documentation provides you official information, guides,training as well as API reference for developing Android Apps.Previously, offline documenation was provided officially by the Android Dev team, but now it has been handled by the community.
Offline Documentation is not needed for developing Android Apps but it helps you alot when you need access on official guides,reference and most importantly the API reference, all available for offline browsing.
