How to get a versionName in react-native app on Android?

Question

I\'ve made a timestamped versionName in build.gradle like 20150707.1125. I want to show the version of the package in react-native app in about window. How I could get vers

Answer 1

I used as reference the answer by @Marcos Demetrio

But I was using expo, so I did this:

import {expo} from '../../app.json'

And in the Component:

<Label>{expo.version}</Label>          

No package install needed.

Answer 2

import { version } from './package.json';

Answer 3

I tried most of the thing to fix this nicely and I and happy to see detailed description for doing everything that I needed react-native-version-check

import { Linking } from 'react-native';
import VersionCheck from 'react-native-version-check';

VersionCheck.needUpdate()
  .then(async res => {
    console.log(res.isNeeded);    // true
    if (res.isNeeded) {
      Linking.openURL(await VersionCheck.getStoreUrl());  // open store if update is needed.
    }
  });

I couldn't get the package react-native-device-info to work. Ran into this issue Might need some gradle and java changes to make it fly.

Anyhow I got what I needed react-native-version-number. And I am happy with it.

import VersionNumber from 'react-native-version-number';

console.log('appVersion:', VersionNumber.appVersion)

Oh, and as it relates to gleaning the version from package.json. It feels wrong to me. I mean I had to try it just to see if it would work. I didn't realize that resource would be available at runtime on the device. It does work, but I also have some buildTypes debug foo going on in my build.gradle I learned here. So its nice to be getting the versionName like 0.1.7-debug straight from the horses mouth.

I've successfully used the React Native Device Info component to get the build details as specified in the Gradle config.

Once installed you can use:

DeviceInfo.getVersion()

To output the version, and:

DeviceInfo.getBuildNumber()

To get the build number.

Answer 6

You can use react-native-device-info

And you can get app version for both iOS and Android by calling following method.

const version = DeviceInfo.getVersion();

// iOS: "1.0"
// Android: "1.0"

Hope this will help.
