Build Warning : Mapping new ns to old ns

Question

Try deleting and reinstalling the SDK platforms. Delete the folders in ~\Android\Sdk\platforms and download the SDKs you need.

Edit: The above somehow resolved the issue before, but I ran into the same problem again when more external packages were updated. This time, deleting the SDK platforms didn’t work. Instead, I updated Gradle in two locations in my project:

android/build.gradle

buildscript {
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.2.1' // Update this line
        ...
    }
}

Note: 7.2.1 for the Android Gradle Plugin is the latest stable release present at this time in Google’s Maven repository. To check for newer versions, visit https://maven.google.com, or the release notes. Under com.android.tools.build > gradle you will find the versions available for Android.

android/gradle/wrapper/gradle-wrapper.properties

...
distributionUrl=https\://services.gradle.org/distributions/gradle-7.2-all.zip # Update this line

Updating the plugin in these two spots resolved the issue for me this time.
