There are multiple similar questions everywhere across the internet and so far no provided solutions work.
I use Android Studio 4.0.0, and maybe this is the problem.

So far I got these settings in my system variables:
Environment variables

Also PATH variable:
PATH variable

Here is what react-native info outputs:

And also, just in case, react-native doctor output:

Additional important information: The attempt to fix issue with SDK via doctor cannot be successful since it fails with "permission denied" on attempting to install Androd Command Line Tools despite the fact that the PowerShell and IDE are launched with admin privileges.

  • Did you try to redownload your sdk? – Ruben Meiring Jun 29 '20 at 09:37
  • I just did. Right after your suggestion. No use. I'm almost certain that this is due to the wrong variables configuration. – Xeizzeth Jun 29 '20 at 10:39
  • checking through your post again, I cant see in the logs where it finds the URL for the sdk location, check if you actually have the sdk location assigned – Ruben Meiring Jun 29 '20 at 10:44
  • ANDROID_SDK_HOME should also point to the SDK location I think, but at the moment its pointing to C:/Users/zarifov, make it the same as the ANDROID_HOME and ANDROID_SDK_ROOT – Ruben Meiring Jun 29 '20 at 10:46
  • Actually SDK_HOME should point to the "default" location (in android terms), which is user's profile. It is said by android studio itself, once it coudn't launch even an emulator. And yes - it was set to the same location, before I changed it to the user profile. – Xeizzeth Jun 29 '20 at 10:49
  • @RubenMeiring Actually yes - how to see where it tries to see the sdk location? It would greatly help. (googling this question right now as well). – Xeizzeth Jun 29 '20 at 10:51
  • Maybe something here could help https://stackoverflow.com/questions/32634352/react-native-android-build-failed-sdk-location-not-found – Ruben Meiring Jun 29 '20 at 10:54
  • Was there already. Nothing works so far. – Xeizzeth Jun 29 '20 at 11:19

I have a solution: install Android SDK Command-line Tools:

The correct way of solving it involves a two-step process. This is what worked for me:

STEP 1

Install Android SDK Command-line tools. After doing so, once you call npx react-native doctor you'll no longer see Versions found: N/A (providing that you already have some SDK version(s) installed in your machine, which I assume is the case). After installing it you should see something like:

react-native doctor after installing Android SDK Command-line tools

STEP 2

If version found does not match the version react-native supports (version supported) then you need to download the correct SDK version to make them match. When doing so you need to be careful as you have to do two more steps within android studio menus: tools --> sdk manager --> Android SDK. Once here:

STEP 2.1 Select SDK Platforms and choose Platform and Sources for you API Level (tick "show package details" checkbox):

enter image description here

STEP 2.2 Select SDK Tools and tick the box of the API version you need to install to match it with react needs (again make sure you tick "show package details" checkbox):

enter image description here

Now click OK and install everything. Close your terminal and run it again. When using react-native doctor comand you'll find the problem is solved:

You must install support libraries, you can do this by opening Android Studio, SDK manager and install support library version 28.0.3

I had this same issue. Mine was even showing that:

    Android
 ✓ JDK
 ✖ Android Studio - Required for building and installing your app on Android
 ✖ Android SDK - Required for building and installing your app on Android   
   - Versions found: N/A
   - Version supported: 29.0.3
 ✓ ANDROID_HOME

 › Press e to try to fix errors.
 › Press w to try to fix warnings.
 › Press Enter to exit.

I got fed up with all the steps that are online that are not working and just clicked on 'e'. It took its time and installed the said missing programs (note that I already installed Android studio and all the SDK instructions on react-native docs before now but for some reason it was not being detected)

When I ran npx react-native doctor, the issue was resolved:

  • Thank you for the reply. Although I'm no longer working on this project your reply is still appreciated since somebody still might stumble upon this issue and they could find your reply to be the solution. – Xeizzeth Jan 25 '22 at 04:47

Install Android SDK command line tool along with desired Android SDK build tool. Then check npx react-native doctor

I had exactly this problem and managed to solve it by doing something simple:

In the 'gradle-wrapper.properties' file, I changed the version of the gradle in distributionUrl value.

It was like that distributionUrl=https\://services.gradle.org/distributions/gradle-6.2-all.zip and I changed to distributionUrl=https\://services.gradle.org/distributions/gradle-6.4.1-all.zip.

Now it's working!!

  • Went ahead and made sure my installations mirror your configuration, then I went ahead some more and just installed all of them - no success in both cases. – Xeizzeth Jun 30 '20 at 05:25
