How to import react native project in android studio

I started development of the android application using atom text editor. It is working fine as long I am writing code in JS and JSX.

I have to do functionality which is not available in react native, so I need to write java code as like https://facebook.github.io/react-native/docs/native-modules-android.html

ToastModule.java

package com.facebook.react.modules.toast;

import android.widget.Toast;

import com.facebook.react.bridge.NativeModule;
import com.facebook.react.bridge.ReactApplicationContext;
import com.facebook.react.bridge.ReactContext;
import com.facebook.react.bridge.ReactContextBaseJavaModule;
import com.facebook.react.bridge.ReactMethod;

import java.util.Map;

public class ToastModule extends ReactContextBaseJavaModule {

  private static final String DURATION_SHORT_KEY = "SHORT";
  private static final String DURATION_LONG_KEY = "LONG";

  public ToastModule(ReactApplicationContext reactContext) {
    super(reactContext);
  }
}

I do not want to code Java in atom as suggestions are not working. Can we import our react native project in android studio where all in built classes of react native are available so I can have suggestion of classes/methods while writing code.

Is there any way to do this ?

Go to Android Studio--> then open the Android folder of your RN project

If you want code suggestions, Android Studio will help you while typing ;)
