找不到用于本机反应的 Android SDK

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:

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.

Answer 1

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

Answer 2

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 3

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

    Android
 ✓ JDK

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

 › 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:

Answer 4

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

Answer 5

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

Answer 6

i can see package deatils. its look lik this enter image description here

Answer 7

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:

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):

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):

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:
