Facing an error when running my android app on an emulator

Question

Hi I'm just starting to learn how to code on android studio.

After running npm run android on my terminal, I've faced some errors which I could not solve.

The error message is as follows :

XXXX-MacBook-Pro:first-app XXXX$ npm run android

[email protected] android /Users/XXXX/Desktop/React Native/first-app react-native run-android

Scanning folders for symlinks in /Users/XXXX/Desktop/React Native/first-app/node_modules (8ms) Starting JS server... Building and installing the app on the device (cd android && ./gradlew installDebug)...

FAILURE: Build failed with an exception.

What went wrong: Could not resolve all files for configuration ':app:_internal_aapt2_binary'. Could not find com.android.tools.build:aapt2:3.2.0-4818971.

I hope you guys can help me with it.

Answer 1

I managed to fix this issue by adding a line google() to ~/my-app/android/build.gradle in the following section:

allprojects {
    respositories{
        google() //right here
    }
}

Just a guess, but I believe it is a regression to do with the new Android Studio 3.2.0 release.
