I'm using windows 8.1. with
react-native-cli: 1.0.0 and
react-native: 0.31.0
After adding react-native-maps to the project, I ran command react-native upgrade and given Y to all questions.
Then linked deps with rnpm link as well as come changes to MainApplication.java file too.
Here are changes to MainApplication.java:
// Other imports ...
import com.airbnb.android.react.maps.MapsPackage;
public class MainApplication extends Application implements ReactApplication {
private final ReactNativeHost mReactNativeHost = new ReactNativeHost(this) {
@Override
protected boolean getUseDeveloperSupport() {
return BuildConfig.DEBUG;
}
@Override
protected List<ReactPackage> getPackages() {
return Arrays.<ReactPackage>asList(
new MainReactPackage(),
new MapsPackage() // I have added this for react-native-maps
);
}
};
@Override
public ReactNativeHost getReactNativeHost() {
return mReactNativeHost;
}
}
Now I'm getting error when I run the command: react-native run-android
λ react-native run-android
JS server already running.

Could not install the app on the device, read the error above for details.
Make sure you have an Android emulator running or a device connected and have set up your Android development environment:
https://facebook.github.io/react-native/docs/android-setup.html
I have no idea about this error. Saw some questions similar to this but could not find the answer. I'm new to React-Native and Android development so I'm having hard time understanding this stuff.
to be more specific:
in your
MainApplication.javafile, change,on this
that got it building for me, at least
just run this from root of your project with cmd:
cd android && gradlew cleanUse these steps
This error occurs in my system whenever the emulator is updated.
The problem for me was that, the packager was running in the background from the previous build.
You might just try to close the packager server and start it with
That was successful for my problem.
This problem usually comes from gradle dependency in new components, i can see you have installed react-native-maps
you can solve it by cleaning the project.
