error Unrecognized command "build-android". Did you mean "run-android"?

Issue

According to the official React Native docs,

I am trying to generate a .aab file for release. When I run the command

npx react-native build-android --mode=release

I get this error

error Unrecognized command "build-android". Did you mean "run-android"?

Solution

For react-native versions < 0.72. To generate .aab for release, you need to go to Android folder and run the following commands

.\gradlew clean

then

.\gradlew bundleRelease

According to this documentation
