If you can get a Internet connection then download Android SDK and NDK offline zip file and extract in sdk folder. Or you can get full setup file in USB from another computer, like from your friend or colleague. It is free software and you can use it for personal use. The Android Software Development Kit (SDK) is a crucial part of Android development for beginners to come to grips with. It's a selection of files bundled together that you will need to begin.
The sdkmanager is a command line tool that allows you to view, install,update, and uninstall packages for the Android SDK. If you're using AndroidStudio, then you do not need to use this tool and you can instead manage yourSDK packages from the IDE.
The sdkmanager tool is provided in the Android SDK Tools package(25.2.3 and higher) and is located inandroid_sdk/tools/bin/.
Usage
You can use the sdkmanager to perform the following tasks.
List installed and available packages
Use the channel option to include a package from a channel up to andincludingchannel_id. For example, specify the canary channel to list packagesfrom all channels.
--channel=0 or remove the --channeloption entirely.Install packages
The packages argument is an SDK-style path as shown withthe --list command, wrapped in quotes (for example,'build-tools;29.0.2' or'platforms;android-28'). You can pass multiple packagepaths, separated with a space, but they must each be wrapped in their own set ofquotes.
For example, here's how to install the latest platform tools (which includesadb and fastboot) and the SDK tools for API level 28:
Alternatively, you can pass a text file that specifies all packages:
The package_file argument is the location of a text file in whicheach line is an SDK-style path of a package to install (without quotes).
To uninstall, simply add the --uninstall flag:
To install CMake or the NDK, use the following syntax:
For example, use the following command to install the specified NDK version regardlessof which channel it is currently on.
Update all installed packages
Options
The following table lists the available options for the above commands.
| Option | Description |
|---|---|
--sdk_root=path | Use the specified SDK path instead of the SDK containing this tool |
--channel=channel_id | Include packages in channels up to and including channel_id. Available channels are:
|
--include_obsolete | Include obsolete packages in the package listing or package updates. For use with --list and --update only. |
--no_https | Force all connections to use HTTP rather than HTTPS. |
--verbose | Verbose output mode. Errors, warnings and informational messages are printed. |
--proxy={http | socks} | Connect via a proxy of the given type: either http for high level protocols such as HTTP or FTP, or socks for a SOCKS (V4 or V5) proxy. |
--proxy_host={IP_address | DNS_address} | IP or DNS address of the proxy to use. |
--proxy_port=port_number | Proxy port number to connect to. |

Overview
This guide explains how to use the Xamarin Android SDK Manager inVisual Studio and Visual Studio for Mac.
Note
This guide applies to Visual Studio 2019, Visual Studio 2017, and Visual Studio for Mac.
The Xamarin Android SDK Manager (installed as part of the Mobiledevelopment with .NET workload) helps you download the latest Androidcomponents that you need for developing your Xamarin.Android app. Itreplaces Google's standalone SDK Manager, which has been deprecated.
Requirements
To use the Xamarin Android SDK Manager, you will need the following:
Visual Studio Tools for Xamarin version 4.10.0 or later(installed as part of the Mobile development with .NET workload).
The Xamarin Android SDK Manager also requires the Java Development Kit(which is automatically installed with Xamarin.Android). There areseveral JDK alternatives to choose from:
By default, Xamarin.Android usesJDK 8,which is required if you are developing for API level 24 or greater(JDK 8 also supports API levels earlier than 24).
You can continue to use JDK 7if you are developing specifically for API level 23 or earlier.
If you are using Visual Studio 15.8 Preview 5 or later, you can tryusing Microsoft's Mobile OpenJDK Distributionrather than JDK 8.
SDK Manager
To start the SDK Manager in Visual Studio, click Tools > Android >Android SDK Manager:
The Android SDK Manager opens in the Android SDKs andTools screen. This screen has two tabs – Platforms andTools:
The Android SDKs and Tools screen is described in more detail inthe following sections.
Android SDK location
The Android SDK location is configured at the top of the Android SDKsand Tools screen, as seen in the previous screenshot. This location mustbe configured correctly before the Platforms and Tools tabswill function properly. You may need to set the location of the AndroidSDK for one or more of the following reasons:
The Android SDK Manager was unable to locate the Android SDK.
You have installed the Android SDK in a alternate (non-default) location.
To set the location of the Android SDK, click the ellipsis (…)button to the far right of Android SDK Location. This opens theBrowse For Folder dialog to use for navigating to the location ofthe Android SDK. In the following screenshot, the Android SDK underProgram Files (x86)Android is being selected:
When you click OK, the SDK Manager will manage the Android SDK thatis installed at the selected location.
Tools tab
The Tools tab displays a list of tools and extras. Use this tabto install the Android SDK tools, platform tools, and build tools.Also, you can install the Android Emulator, the low-level debugger(LLDB), the NDK, HAXM acceleration, and Google Play libraries.
For example, to download the Google Android Emulator package, click thecheck mark next to Android Emulator and click the Apply Changesbutton:
A dialog may be shown with the message, The following package requiresthat you accept its license terms before installing:
Click Accept if you accept the Terms and Conditions. At the bottomof the window, a progress bar indicates download and installationprogress. After the installation completes, the Tools tab will showthat the selected tools and extras were installed.
Platforms tab
The Platforms tab displays a list of platform SDK versions alongwith other resources (like system images) for each platform:
This screen lists the Android version (such as Android 8.0), thecode name (Oreo), the API level (such as 26), and the sizes ofthe components for that platform (such as 1 GB). You use thePlatforms tab to install components for the Android API level thatyou want to target. For more information about Android versions and APIlevels, seeUnderstanding Android API Levels.
When all components of a platform are installed, a checkmark appears nextto the platform name. If not all components of a platform areinstalled, the box for that platform is filled.You can expand a platform to see its components (and which componentsare installed) by clicking the + box to the left of the platform.Click - to unexpand the component listing for a platform.
To add another platform to the SDK, click the box next to the platformuntil the checkmark appears to install all of its components, thenclick Apply Changes:
To install only specific components, click the box next to the platformonce. You can then select any individual components that you need:
Notice that the number of components to install appears next to theApply Changes button. After you click the Apply Changes button,you will see the License Acceptance screen as shown earlier.Click Accept if you accept the Terms and Conditions. You may seethis dialog more than one time when there are multiple components toinstall. At the bottom of the window, a progress bar will indicatedownload and installation progress. When the download and installationprocess completes (this can take many minutes, depending on how manycomponents need to be downloaded), the added components are marked witha checkmark and listed as Installed.
Repository selection
By default, the Android SDK Manager downloads platform components andtools from a Microsoft-managed repository. If you need access toexperimental alpha/beta platforms and tools that are not yet availablein the Microsoft repository, you can switch the SDK Manager to useGoogle's repository. To make this switch, click the gear icon in thelower right-hand corner and select Repository > Google(Unsupported):
When the Google repository is selected, additional packages may appearin the Platforms tab that were not available previously. (In theabove screenshot, Android SDK Platform 28 was added by switching tothe Google repository.) Keep in mind that use of the Google repositoryis unsupported and is therefore not recommended for everydaydevelopment.
To switch back to the supported repository of platforms and tools,click Microsoft (Recommended). This restores the list of packagesand tools to the default selection.
Requirements
To use the Xamarin Android SDK Manager, you will need the following:
- Visual Studio for Mac 7.5 (or later).
The Xamarin Android SDK Manager also requires the Java Development Kit(which is automatically installed with Xamarin.Android). There areseveral JDK alternatives to choose from:
By default, Xamarin.Android usesJDK 8,which is required if you are developing for API level 24 or greater(JDK 8 also supports API levels earlier than 24).
You can continue to use JDK 7if you are developing specifically for API level 23 or earlier.
If you are using Visual Studio for Mac 7.7 or later, you can tryusing Microsoft's Mobile OpenJDK Distributionrather than JDK 8.

To start the SDK Manager in Visual Studio for Mac, click Tools > SDK Manager:
The Android SDK Manager opens in the Preferences window, whichcontains three tabs, Platforms, Tools, and Locations:
The tabs of the Android SDK Manager are described in thefollowing sections.
Locations tab
The Locations tab has three settings for configuring the locationsof the Android SDK, Android NDK, and the Java SDK (JDK). Theselocations must be configured correctly before the Platforms andTools tabs will function properly.
When the SDK Manager starts, it automatically determines the path foreach installed package and indicates that it was Found by placing agreen checkmark icon next to the path:
Click the Reset to Defaults button to cause the SDK Manager to lookfor the SDK, NDK, and JDK at their default locations.
Typically, you use the Locations tab to modify the location of theAndroid SDK and/or the Java JDK. You do not need to install the NDK todevelop Xamarin.Android apps – the NDK is used only when you needto develop parts of your app using native-code languages such as C andC++.
