Description

Cannot find Android SDK, JDK, or Android_HOME even though its all available, shown below:

not sure if bug or other problem. This causes me to unable to do react-native run-android. Always shows the message below when I try to run it:

This worked for me on windows 10:

Install android command line tools from android studio SDK manager (SDK tools tab). then add <YOUR_ANDROID_SDK_PATH>\cmdline-tools\latest\bin to PATH environment variables

Also work for MacOS. For me, I just download Android SDK Command-line Tools : Android Studio -> Preferences -> search for sdk -> Click SDK Tools -> Tick on Android SDK Command-line Tools-> Click OK to download. Then, the doctor should be able to find Android SDK.
