Solution
It seems that necessary Android 27 API’s are missing in your Android sdk directory. go to ~/library/android/sdk/tools/bin and run sdkmanager –list to check if you have platform-tools and platforms;android-27 installed. If not, then you can install them by running sdkmanager “platform-tools” “platforms;android-27”
If you have Android Studio, then you can install them via Android Studio’s GUI, too.
- open file menu—> project structure—>project settings—>project
- check your project SDK
- also check >>>project structure—>platform settings—>sdks
- give same SDK and click ok
- try to run project
Try running this command:
