React Native Doctor is unable to detect the Android SDK in Windows 10

[bogdanbaghiu]

Hello I tried to exec the npx react-native doctor and obtain that:

I have installed the android-sk 33 and 34, but supported .b33.0.0. I need help please!!

The npx react-native info get that:

And I installed the latest version (11) from Android SDK Command-line Tools

React native project to test: https://github.com/bogdanbaghiu/test_image_colors

But the check of Android Sdk not pass :(

Hey @bogdanbaghiu, that's because you're using expo in your project. So you should use Expo CLI to manage your Expo project, I also see react-native-windows inside your package.json, if you want to use out of tree platforms you should use prebuild, and use React Native Community CLI.

@szymonrybczak Thanks for your answer! You were right that I had the added library in my package.json and after that I have made several changes to my package.json that I invite you to look at and try. I have made some progress but I will tell you what I have been discovering.

I Delete the node_modules, android folder and package-lock. I did an install npx expo install react-native-image-colors library, I already had it installed but I did it so that the yarn.lock file updates all the dependencies. Then I did an npm install that installed all the dependencies in my project. Next I launched the npx expo run:android command and it created an android build again. It launched successfully on my device. Finally I told myself that I am going to check if the npx react-native doctor command has solved my problem and apparently it still looked the same.

Then I realized that if I delete the android folder from my project I get the following:

I have noticed that the npx expo run:android command generates the android build but for some reason it says that the Android SDK supported has to be .b33.0.0 and the ones I have installed are 33.0.0

Could you check if the same thing happens to you with my project but on your computer? If it doesn't happen to you, could you please try to guide me to know why it tells me that it needs an sdk with .b in front of 33.0.0?

I'm having the same issue on Apple Silicon and I am NOT using expo. SDK is there but same doctor results.. Thoughts?

Hi @bogdanbaghiu, did you ever figure out why you are seeing the .b in front of the version number? I'm using Expo, and upon running npx react-native doctor I also see that the version supported has a .b prefixed in front of the version number, but I don't know what it's meant to mean.

Any thoughts about this issue? are we the only ones with this problem? What is the other method that most of the other people follow?
