I have created a React-Native Project,When I run react-native run-ios,I get the build successed.But when I run react-native run-android I get this
react-native run-ios
react-native run-android
I have solve it, The error is because Genymotion use its own SDK not custom SDK location.I solved this question with the URL follow:
React-Native, Android, Genymotion: ADB server didn't ACK
thanks for Simon!
