Android standalone app fails to load

Hello,

I’ve built Android standalone app and deployed to Google Playstore, but the app fails to load, stays at loading screen indefinitely (flashing loading logo and 'Made with Expo` text at the bottom)

https://play.google.com/store/apps/details?id=vn.com.bhtech.uet

I’m not sure how to debug this, since opening pusblished version via Expo app still works.

The apk build published on Playstore worked 2 days ago though, only stopped working since yesterday,

Any help will be much appreciated. Thank you.

app.json content:

{
  "expo": {
    "name": "UET News",
    "slug": "uet-hybrid",
    "version": "1.0.0",
    "description": "No description",
    "privacy": "unlisted",
    "sdkVersion": "18.0.0",
    "android": {
      "package": "vn.com.bhtech.uet",
      "versionCode": 2
    },
    "icon": "./app/assets/iconsAssets/app-icon.png",
    "ios": {
      "buildNumber": "2",
      "bundleIdentifier": "vn.com.bhtech.uet",
      "supportsTablet": false
    },
    "loading": {
      "hideExponentText": false,
      "icon": "./app/assets/iconsAssets/loading-icon.png"
    },
    "notification": {
      "color": "#000000",
      "icon": "./app/assets/iconsAssets/notification-icon.png"
    },
    "packagerOpts": {
      "assetExts": ["otf", "ttf"]
    },
    "primaryColor": "#cccccc"
  }
}

Hi! Could you paste the URL to your Expo project? Also, could you upload the APK from the standalone app somewhere and provide a link for that?

@dikaiosune Sure, the link is at:

exp://exp.host/@duyphambhtech/uet-hybrid

And APK can be downloaded here:

https://i.diawi.com/UmrzBr / @expo4rum

If there’s anything else, let me know.

Just to note, iOS standalone app still works, should be available on Apple App Store soon

Hi! Sorry about the delay here. We’re looking into this, hopefully @jesse will have some news to share soon.

@dikaiosune I’m having the same issue with a second app

https://expo.io/@duyphambhtech/hrd-hybrid

Any help is much appreciated.

I’ve finally resolved this problem. This might be due to old API Notifications.getExponentPushTokenAsync

Complete old code (which hangs in Android standalone app, but runs normally in Expo app & iOS standalone app)

import { Permissions, Notifications } from 'expo'

export default async () => {
  // Android remote notification permissions are granted during the app
  // install, so this will only ask on iOS
  let { status } = await Permissions.askAsync(Permissions.REMOTE_NOTIFICATIONS)

  // Stop here if the user did not grant permissions
  if (status !== 'granted') {
    return Promise.resolve(null)
  }

  // Get the token that uniquely identifies this device
  let token = await Notifications.getExponentPushTokenAsync()

  __DEV__ && console.log('token', token)
  // TODO: do something with received token

  return Promise.resolve(token)
}

Similar to code in https://github.com/expo/new-project-template/blob/master/api/registerForPushNotificationsAsync.js

Changing to getExpoPushTokenAsync resolves the problem.

FYI
