[expo-background-fetch] Background fetch is not running

🐛 Bug Report

Summary of Issue

Hi everyone, I’m writing this issue because expo-background-fetch doesn’t work with my project.

Environment

  Expo CLI 3.24.2 environment info:
    System:
      OS: macOS 10.15.6
      Shell: 5.7.1 - /bin/zsh
    Binaries:

Reproducible Demo

I’ve created a little project which is here.

It’s a little app which uses some chunks of code that I’ve seen in this issue.

Expected Behavior vs Actual Behavior

My task function doesn’t work whereas I initialized the tasks.

console.log(
      "Task is running in background each ",
      INTERVAL_TASKS,
      " seconds."
    );

I also try to switch between my actuel version of the npm package to the latest (8.4.0). It doesn’t change

"dependencies": {
    "expo": "~38.0.8",
    "expo-background-fetch": "~8.3.0",
    "expo-status-bar": "^1.0.2",
    "expo-task-manager": "~8.3.0",
    "react": "~16.11.0",
    "react-dom": "~16.11.0",
    "react-native": "https://github.com/expo/react-native/archive/sdk-38.0.2.tar.gz",
    "react-native-web": "~0.11.7"
  },

Any guesses to solve this issue ?

Thanks for your help.

Push notifications should work (but I didn’t try), but not in China for Android which is why I had to go through alternatives that do not involve Google. Another alternative I tried but failed was https://pushy.me/ but that does not work in Expo https://github.com/pushy-me/pushy-react-native/issues/61
