minSdkVersion 16 cannot be smaller than version 19

I am would like to integrate Razorpay into my react-native app. I have installed the razorpay package and have also linked successfully.

However, when I try to run the app I am getting the following errors:

$ react-native run-android

info Starting JS server...
info Building and installing the app on the device (cd android && ./gradlew app:installDebug)...

> Configure project :react-native-razorpay
WARNING: The specified Android SDK Build Tools version (26.0.3) is ignored, as it is below the minimum supported version (28.0.3) for Android Gradle Plugin 3.3.1.
Android SDK Build Tools 28.0.3 will be used.
To suppress this warning, remove "buildToolsVersion '26.0.3'" from your build.gradle file, as each version of the Android Gradle Plugin now has a default version of the build tools.

I have been using Expo to develop mobile apps, and I am very new to Android development. Could you please tell me how can I fix this?

@KakarN I faced same issue today while using Razorpay react-native package. You’re using expo and it’s clearly mentioned in repo README that: The react native plugin is wrapper around native SDK, so it doesn't work with the tools like expo which doesn't support native modules. You can do expo eject and then following instructions: open build.gradle file in android folder and change the value of minSdkVersion from 16 to 19. Hope this resolves your issue. 😄

Downgrade your version ‘audioplayers: ^0.17.1’ to ‘audioplayers: ^0.16.1’ in pubspec.yaml and pub get the dependencies of ‘audioplayers: ^0.16.1’.
