Native React - VS Studio Code - npm run android - Execution failed for task ':app:checkDebugAarMetadata'

Question

I have been getting this error when trying to run npm android build on my native react project. I have gone through the entire android setup along with updating Environment variables. The emulator works but the install fails with the following message:

     What went wrong:

build.gradle as follows:

buildscript {
ext {
    buildToolsVersion = "33.0.0"
    minSdkVersion = 21
    compileSdkVersion = 33
    targetSdkVersion = 33

    // We use NDK 23 which has both M1 support and is the side-by-side NDK version from AGP.
    ndkVersion = "23.1.7779620"
}
repositories {
    google()
    mavenCentral()
}
dependencies {
    classpath("com.android.tools.build:gradle")
    classpath('com.facebook.react:react-native-gradle-plugin')
}

}

I have also run react doctor, it shows the following:

    Android

 ✖ Android SDK - Required for building and installing your app on Android

Answer 1

This might be the answer you are looking for React Native app not running without doing anything in the previous working code

Try checking the SDK version in your android studio settings, Click on SDK Manager, and then SDK tools, and then click on Show Package Details and check if you have ticked 33.0.0 which is required for android development and is mentioned in the development environment setup of react native as well.

Link - https://reactnative.dev/docs/environment-setup

Also few steps

1. run ./gradlew clean and then ./gradlew assembleDebug in the android folder of your project to clean gradle cache
2. Now run ./gradlew build to build android folder and then if it is successful you should be able to run the project.

Answer 2

Open your project on Android studio And follow these steps

Click Tools on Android Studio nav bar

Click SDK Manager

Go on Languages and Frameworks and click Android SDK

Then select Android API 34 and Android 13.0 or you can check that what's your mobile OS version and select also that one.

And click Apply it will install that SDK for you.

After this you show clean your gradle by using ./gradlew clean command and then you can run your project it definately run your project on your mobile.
