React Native App Crashes on Launch in Android (API 19)

Description

I have created a project with react-native-cli

When I launch the app using the command “react-native run-android” on Devices and Emulators with Android API level 21+ App is launching.

But for devices less than API 21, the app crashing on launch.

I have specified in android Gradle minSdk version to 16.

I viewed the stack trace using “adb logcat” the crash was due to OkHttp3 that is used internally in Facebook Flipper, which is expecting API 21+.

I haven’t used any OkHttp3 Dependency explicitly in my app

React Native version:

6.14.4

Steps To Reproduce

1. Create a project using react-native CLI not Expo CLI
2. Navigate to the project folder
3. Connect a device or an emulator with API less than 21
4. run command “react-native run-android” to run the app on the connected device

Expected Results

The app should launch without any crash.
