React Native running android with different version

Question

When I run 'react-native run-android' it always checks 'android-23' version and I don't have any AVD with android-23. Instead I only have android-21. How can I specify android version of android-21?

Answer 1

I would suggest to update your SDK. To do so, you need to open Android Studio. Then, go to Preferences -> Appearance & behaviour -> System Settings -> Android SDK. You will see a few tabs:

1. SDK Platforms Check 'Show Package Details' at the right bottom corner and check the following items under Android 6.0 (Marshmallow): Google APIs, Android SDK Platform 23, Sources for Android SDK

2. SDK Tools Check 'Show Package Details' at the right bottom corner and check the following items:

Android SDK Build Tools 23.* Android Auto API Simulators Intel x86 Emulator Accelator (HAXM installer)

Click on Apply button, wait for everything being installed, and then try to run your project again.
