How can I generate apk file for create-react-native-app (using EXPO.IO component)

Question

I setup my app using create-react-native and I used expo's Video component in my app. How can I keep this video component and generate the apk file? Correct me if I'm wrong: to my understanding npm run eject prevents you from using expo components in the future. So how can I generate the apk file. It doesn't matter if it's signed or unsigned, atleast to me, I just want to email my friend the apk file so he can run it on his phone

Edit: This is not a duplicate of: How can I generate an apk that can run without server with react-native?

As that question asks how to generate an apk file for react-native, mine ask how this works with the specific create-react-native-app build where I am using an expo component

Answer 1

1. Install npm install -g exp

2. edit app.json file in our project

   {
   "expo": {
   "name":"my app",
   "icon":"./logo.png",
   "description":"some description about our project",
   "sdkVersion": "27.0.0",
   "android":{
        "package":"com.johncy.myapp",
         "versionCode":1 , 
         "icon":"./logo.png"
             }
            }
   }
   

3. give the command in our project directory exp build:android

4. Just wait for few mins.It will give an url for our build project.We can download *.apk file from that link.
