Android SDK not found for react-native

Question

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:

Also PATH variable:

Here is what react-native info outputs:

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.

Answer 1

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!!

Answer 2

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

Errors:   2
Warnings: 0 
Usage
 › Press f to try to fix issues.
 › 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:
