Headless task not running on physical device emulator with Android version 10

asrasoft-admin commented 3 months ago

Your Environment

Plugin version: 4.2.2
Platform: Android
OS version (emulator): 14
OS version (physical device): 10
Device manufacturer
React Native version (react-native -v): 0.72.3
Plugin config: { minimumFetchInterval: 15, stopOnTerminate: false, startOnBoot: true, enableHeadless: true, forceAlarmManager: false, requiredNetworkType: BackgroundFetch.NETWORK_TYPE_ANY, requiresCharging: false, requiresDeviceIdle: false, requiresBatteryNotLow: false, requiresStorageNotLow: false, },

Expected Behavior

I expected the headless task registered using Background.registerHeadlessTask to run on my physical device emulator but it does work fine on the emulator with Android version 14.

Actual Behavior

The headless task runs successfully on the emulator with Android version 14, but it does not work on my physical device emulator with Android version 10. I have attempted to manually run the task using the command adb shell cmd jobscheduler run -f com.myapplicationId 999 on my physical device, but it did not trigger the headless task.

Steps to Reproduce

Install the app on the physical device emulator with Android version 10.
Manually run the background task using the command adb shell cmd jobscheduler run -f com.myapplicationId 999.
Check if the headless task is triggered.
Compare the behavior with the emulator running Android version 14.

Context

I am attempting to use the Background.registerHeadlessTask method to register a headless task in my React Native application. The task runs successfully on the emulator with Android version 14, but it fails to run on my physical device emulator with Android version 10. This issue is critical for the functionality of my application as it relies on background tasks for important functionality.

Yeah, but the logs which you have quoted are the logs of my android studio emulator (on which it is working fine, just added for your reference only). This log is shown after when the headless task runs perfectly using the adb command. The issue occurs when i try to run it on my physical device emulator, i have also tested it with multiple devices (Android v10, v11) but the headless task is not running using the command. Even after testing the apk on phone it shows the same result (not running).

This is my index.js:

PushNotification.configure({
  onRegister: function (token) {
    console.log('TOKEN:', token);
  },

  onNotification: function (notification) {
    console.log('NOTIFICATION:', notification);

    if (Platform.OS === 'ios')
      notification.finish(PushNotificationIOS.FetchResult.NoData);
  },

  onAction: function (notification) {
    console.log('ACTION:', notification.action);
    console.log('NOTIFICATION:', notification);
  },

  onRegistrationError: function (err) {
    console.error(err.message, err);
  },

  permissions: {
    alert: true,
    badge: true,
    sound: true,
  },

  popInitialNotification: true,

  requestPermissions: Platform.OS === 'ios',
});

PushNotification.createChannel(
  {
    channelId: 'channel-id',
    channelName: 'Channel Name',
    channelDescription: 'A brief description of the channel',
    soundName: 'default',
    importance: 4,
    vibrate: true,
  },
  created => console.log(`Channel created: ${created}`),
);

const Root = () => {
  return (
    <Provider store={store}>
      <PersistGate loading={null} persistor={persistor}>
        <App />
      </PersistGate>
    </Provider>
  );
};

AppRegistry.registerComponent(appName, () => Root);

const backgroundHeadlessTask = event => {
  if (event.timeout) {
    console.log('[BackgroundFetch] 💀 HeadlessTask TIMEOUT: ', event.taskId);
    BackgroundFetch.finish(event.taskId);
    return;
  }

  console.log(
    'This is the headless event: ',
    new Date().toLocaleString(),
    event,
  );

  PushNotification.localNotification({
    channelId: 'channel-id',
    title: 'Background Task Completed ',
    message:
      'Your headless task has been triggered with task id ' + event.taskId,
  });

  BackgroundFetch.finish(event.taskId);
};

BackgroundFetch.registerHeadlessTask(backgroundHeadlessTask);
