android compilation version sdk version too low

[danielzzz]

I have fixed it with: (26.0.1 is the sdk I have installed)

`sed -i -e 's/compileSdkVersion 23/compileSdkVersion 26/g' node_modules/react-native-contacts-wrapper/android/app/build.gradle
sed -i -e 's/23.0.1/26.0.1/g' node_modules/react-native-contacts-wrapper/android/app/build.gradle
sed -i -e 's/targetSdkVersion 23/targetSdkVersion 26/g' node_modules/react-native-contacts-wrapper/android/app/build.gradle

`
