Not able to Install Android SDK Platform

React Native Documentation Recommends SDK Platform Android 6.0 (Marshmallow), When I try to install, it is dim, and I am not able to download and install. See image here:

the sdk path can not include space!!!!
so you can download the sdk in D:\sdk

change directory to android sdk directory, then go deeper into tools/bin:
run following command, any meaningful error must get visible in terminal, so you can detect the impediments against downloading platform:
sdkmanager "platform-tools" "platforms;android-23"

Create a non-spaced directory for example C:\AndroidSdk and move the content of C:\Users\Kashif Nazir\AppData\Local\Android\Sdk to the new folder. Then, in Android Studio SDK Manager, change the SDK location to C:\AndroidSdk. Now, you'll be able to download and save different SDKs.

Where to download the Android SDK?

I have downloaded Android Studio and SDK Tools from here. However, the studio asks about SDK path and when I provide the tools folder, it says it is not valid. When I search for SDK, pages refer to the studio page. Where can I download the SDK manager?

SDK manager is available under Tools menu of Android Studio:
By default Android Studio downloads the SDK on C:\Users\<username>\AppData\Local\Android\sdk
You can select this dir in your Android Studio.
If you don't find the SDK Manager then download the sdk-tools. You will SDK Manager under bin folder

I had the same problem. I just closed the popup asking for the SDk path as I had deleted the whole sdk folder files. Even though the Android Studio software states it can't continue without a SDk installation, I was able to click the errors away and like stated above start the SDk manager.
I pointed the SDK path to my empty sdk folder and then it gave a list of files it was
going to (download and) install. After that (when the first download and installation
completes) you can further configure the packages to your needs. it will then further download and install the selected packages. I hope this helps. (pls give it a thumbs up;-)

you can find here
click tools from android studio( from toolbar) -> click android-> sdk manager

Where can I find the sdk manager?
You can find it Top of android studio window Tools-->SDK Manager
You should give the SDK Location path that is generally available at
/home/user/Android/Sdk.
Try this..!

Can't find SDK Manager.exe in Android SDK folder

I need to install some packages in Android SDK Manager, but in my SDK folder there isn't the .exe file (There is only the AVD Manager and the folders).
How can I find it? My SDK works normally with Android Studio, without problems, it's strange that SDK Manager.exe isn't there.

I had to install an older version
https://dl.google.com/android/installer_r24.4.1-windows.exe
and update it. Going from there worked

To open the SDK Manager from Android Studio, click Tools > Android > SDK Manager or click SDK Manager in the toolbar. If you're not using Android Studio, you can download tools using the sdkmanager command-line tool.
Check this link: https://developer.android.com/studio/intro/update.html#sdk-manager

I found C:\NVPACK\android-sdk-windows\tools\android.bat
When I ran it, it brought up SDK Manager.
Which was nice, because I couldn't find SDK Manager in the C:\NVPACK\android-sdk-windows\lib folder like I was told it would be there.

You can find Android SDK Manager.exe file in the following folder:
C:\Users[account]\AppData\Local\Android\sdk (sdk1 in my case)
You can tap on that and you will get the Android SDK Manager screen.

Go to android_sdk/tools/bin/ open cmd and type sdkmanager and hit enter you can use command prompt for it

You can find sdk manager under command-line tools, which you will have to download by clicking the configure drop-down link under the android studio start-up wizard.
C:\Users[account]\AppData\Local\Android\sdk\cmdline-tools\latest\bin

C:\Users[account]\AppData\Local\Android\sdk\cmdline-tools\latest\bin
I had trouble running from here because I didn't have the right permission. I was trying to update my SDK. I got it running from another folder on my system with the command line command:
"C:/Program Files (x86)/Android/android-sdk/cmdline-tools/7.0/bin/sdkmanager.bat" --update --sdk_root="C:/Program Files (x86)/Android/android-sdk/cmdline-tools"
On Visual Studio 2022 you can look under Tools/Android/Android SDK Manager

Sdk Manager not opening from eclipse

SDK Manager is not opening from eclipse. An initialization screen comes but the SDK Manager doesn't open. I have tried renaming android.bat file but that doesnt work. Re-installing has also been tried.

The possible reason for this to happen is you might have installed the plugin in a wrong way or the destination of the file might have changed by some means.
Make sure these 2 are correct on the 1st place.
If you are confident about these 2 are proper. Make sure the actual SDK_Manager.exe runs directly from its folder destination if double clicked.
which will be present in your android SDK path--->\Android\android-sdk\SDK Manager.exe

Open android.bat in sdk/tools folder by right click on it and click edit
find the line-
set java_exe=
edit it to your path to java.exe like
set java_exe=C:\Program Files\Java\jre7\bin\java.exe
then delete the next line which is
call lib\find_java.bat
This one worked for me......

After 2 days of frustration not getting solution to launch SDK Manager manually and in Eclipse. Finally, I figured out the solution and whatever solution available elsewhere is not correct on recent development. Thought of adding this info of Android SDK for new to mobile testing enthusiast:
Android encourages users to use Android IDE, so you don't find Android ADT bundle zip file in the site. You may need to download from untrusted source if you want to configure SDK to Eclipse manually.
Solution:
Download JDK, install it, set environment variables for JDK and JRE in your system. (if not sure, please see videos of how to install JDK)
Download Eclipse, unzip it and launch Eclipse
In Eclipse, Go to Windows and click Install new software
Enter this url in work-with: https://dl-ssl.google.com/android/eclipse/ and press Enter
Select Developer Tools checkbox and click Next and finish
Click Ok for permission in popup
Click OK to restart Eclipse
Click Cancel in setting SDK in preferences
Parallely, Android Installation Tool windows opens up, click next
Select automatically downloading Android SDK tools and api versions
It downloads all required tool, it restarts the eclipse, sets preferences,
Now you can launch SDK Manager from Eclipse or go to SDK tools folder and launch Android in tools folder.

The reason of this is using newer version of android sdk tools.
Eclipse supports sdk tools version 25.2.5 and build-tools version 25.0.3. The reason is google has removed some optional/deprecated tools from sdk tools in release 25.3.0. But eclipse needs them to work with android projects. So the thing you can do is delete tools folder from your sdk and download eclipse supported version
Android SDK Tools:
https://dl-ssl.google.com/android/repository/tools_r25.2.5-windows.zip
https://dl-ssl.google.com/android/repository/tools_r25.2.5-linux.zip
https://dl.google.com/android/repository/tools_r25.2.5-macosx.zip
Extract them in your sdk installation directory.
You can now access to SDK manager by using the android command, which is located in tools directory of your sdk. You can also do this from eclipse.
Note that Eclipse supports build-tools version 25.0.3 and older, so you will have to download them. For other tools you can select latest version. They are supported by eclipse.

Android SDK failed to install

I saw a good tutorial on youtube to install the Android SDK on windows, i attempted it on my window 7 pc. I tried many times but still i failed. I have java JDK and Eclipse latest version installed but the only problem is that Android SDK didn't able to fetch some packages and i am unable to use it. The following error occurs:
How to deal with this problem? I want to learn and develop Android apps.

Try to remove everything related to Android and Java SDK as well as Eclipse. Try to install as follows:
Download and install JDK (java)
Download and install Eclipse
Download and install Android SDK
While downloading Android SDK try to do some if it does not fetch the files go to the Tools -> options -> and there checked Force https ok!
You can also download the ADT plugin and add it through Eclipse.
I think it will work fine. Go to this link which has whole latest SDK and installation ideas.
If i told you whatever follow the same patter and you will get it.
If you don't succeed in getting your SDK installed then I say you try to repair your computer by installing the fresh copy of Window 7 OS and try to choose English language this time.

First of all :
uninstal android SDK then check to remove any traces folder related to android and remove it manually from Program Files folder and from Documents and Settings folder ,
then uninstall java JDK also and eclipse ,
( which mean clean your computer from any thing related to android development preparation ) ,
now start again as follow :
1- Download latest java from this link : http://jdk7.java.net/download.html
then install it .
2- download latest android SDK from this link: http://developer.android.com/sdk/index.html
then install it , once finish install dont run it .
3- download latest eclipse from this link : http://www.eclipse.org/downloads/packages/eclipse-ide-java-ee-developers/junor
copy zip file to C folder and extract it in C folder it self ,
RUN ECLIPSE THEN :
1-Downloading the ADT Plugin :
a) Start Eclipse, then select Help > Install New Software.
b) Click Add, in the top-right corner:
In the Add Repository dialog that appears write this
for the Name : ADT Plugin,
and the following URL for the Location:http://dl-ssl.google.com/android/eclipse/
Then Click OK.
d) in the software dialog, select the checkbox next to
developer tools and clicks next.
e) in the next window, you will see a list of the tools to download ,
click next.
f) Read and accept the license agreements, click Finish.
H) When the installation completes, restart Eclipse.
2- Select Window > Preferences... to open the Preferences panel
a) Select Android from the left panel.
b) For the SDK Location in the main panel
click browse… and locate your downloaded SDK directory
then Click Apply, then OK.
3-open in eclipse: window then Android SDK manger and download any platform you want to start development with it .
some times maybe due to busy server of android site it gave error then later time it will fetch all download package you predetermined and download it succesfully .
hope this help .

Instead of the video tutorial, try this official tutorial:
http://developer.android.com/sdk/installing.html
It mentions about the alternate links also from where you can update the sdk.
Edit:
If you are still facing the problem, you can try this hack instead. You'd need another PC for that. What I can tell you that there must be some problem in your PC, so try downloading the required packages on any other PC. (Though you can still work with basic package, if you just want to learn and no to target a specific Android OS version).
After downloading, just go to the android SDK folder on the second PC, copy it in a pen drive and just paste the folder on your existing installation.
I always do this hack whenever I need to install the SDK on a PC without any internet connection and voila!! It works every time. Let me know if it worked for you or not.

I faced similar problem during the installation of SDK on my PC.
Start SDK manager from All programs and try to install APIS.I guess you are trying to install these from Eclipse SDK manager button.Starting SDk Manager from your Eclipse cause this problem. Both are same. But it worked for me.

You could try removing what you have and starting again from the beginning. I'm also on Windows 7, and I highly recommend downloading the zip file (not the installer) for the SDK and extracting it to C:\. It should automatically create a folder named "android-sdk-windows" but you can rename it if you wish. Then run the SDK Manager and start downloading packages. It may help to babysit the package downloader and jiggle your mouse every minute or so (yes, that sounds silly, but it actually made a difference for me because the downloads kept stopping partway through when I didn't do anything).

Try this.
Tools -> options -> check Force https ...

Download the latest sdk from http://developer.android.com/sdk/index.html and try again ! It should not appear again for sure.

are you running the sdk manager from administrator?? If not , right click on your SDK Manager and select Run as Administrator.. May be that will help...

For me the SDK was very tricky, too. It didn't get all the packages and downloaded very slow (about 15-20 kbps with 24 Mbps connection). Then I tried to run the program with administrator privileges and it fixed the problems.

Make sure Android SDK, JDK, and Eclipse are all either 64 bit or 32 bit. If one is different (e.g. Eclipse is 32-bit while the others are 64-bit), you will get errors.

Setup your Android Environment in easy way.
Required Files:
Java Development Kit (JDK) Download
Eclipse – Eclipse 3.6.1 or Helios is the version I’m using. Download
Android Development Tools (ADT) Plugin – custom plugin so we can build Android applications using Eclipse IDE. Download
Android SDK Starter Package – includes the core SDK Tools. Download
Android SDK Tools, revision 10 – the complete tools component of the SDK. Download
Android SDK Platform-tools, revision 3 – platform tools component of the SDK. Download
Android SDK Platform – our target Android OS.
Android SDK Platform:
[Android SDK Platform 3.0, revision 1 (Honeycomb)] : https://dl-ssl.google.com/android/repository/android-3.0_r01-linux.zip
[Android SDK Samples for Android API 11, revision 1] : https://dl-ssl.google.com/android/repository/samples-3.0_r01-linux.zip
[Android SDK Platform 2.3.3._r1 (Gingerbread)] : http://dl-ssl.google.com/android/repository/android-2.3.3_r01-linux.zip

[Android SDK Samples for Android API 8, revision 1] : http://dl-ssl.google.com/android/repository/samples-2.2_r01-linux.zip
STEPS:
Install the JDK using the default setup.
On your Android developer folder (ex. C:\Developers\Android) place all the zip files you just downloaded.
Create a workspace folder on your home folder (ex. C:\Developers\Android\workspace).
Unzip the Android SDK Starter Package (android-sdk_r10-windows.zip). NOTE: I suggest to use WinRAR so we can just right-click the zip file and then choose Extract Here
We now have the android-sdk-windows folder on our android developer folder. Inside this folder, delete the tools folder. Move the Android SDK Tools (tools_r10-windows.zip) and Android SDK Platform-tools (platform-tools_r03-windows.zip) zip files to this folder. Unzip them and rename as tools andplatform-tools respectively.
Inside android-sdk-windows folder there’s a platforms folder. Move and unzip the Android SDK Platform file (android-2.3.3_r01-linux.zip) on this folder.
Inside android-sdk-windows folder, create samples folder. Move and unzip the Android SDK Samples zip file (samples-2.3.3_r01-linux.zip) to this folder.
Unzip the Eclipse file (eclipse-SDK-3.6.1-win32-x86_64.zip).
Inside eclipse folder, run eclipse.exe. It will ask for the workspace folder to use. Choose the workspace folder you created. You can optionally check theUse this as the default and do not ask again checkbox and then click OK.
Still on Eclipse, select Help > Install New Software…. Click Add, in the top-right corner and then click Archive… Browse and select the downloaded ADT zip file (ADT-10.0.0.zip). Enter a name for this update site (ex. ADT Plugin) in the Name field and then click OK.
Check the Developer Tools checkbox or click the Select All button and then click Next button and then accept the defaults. (Sorry, you need to be online as some component need to be downloaded at this part. I’ll update it once I know how to do the offline mode of it). After the installation, Eclipse should be restarted.
On Eclipse, select Window > Preferences. Select Android on the left pane. On SDK location, browse the select the Android SDK folder (android-sdk-windows) then click Apply.
Still on Eclipse, select Windows > Android SDK and AVD Manager. Click the Installed Packages on the left pane and you will notice, there’s SDK Platform Android 2.3.3, API 10, revision 1 and Samples for SDK API 10, revision 1. We are now ready to create virtual devices.
Click Virtual Devices on the left pane. Click New button and give the virtual device a name (ex. Gingerbread). Select Android 2.3.3 API Level 10. Type 512 or more for SD Card size and then click Create AVD button. We are now ready to create our famous “Hello World” application.
