🐛 android alarm manager error with react native >= 0.68

[alwex]

Hello,

Notification scheduled using the alarm manager does not work anymore since react native version 0.68, was working fine on 0.66

Notification works fine when not using the alarm manager.

When triggering a notification with alarm manager I get this error:

[Error: Attempt to invoke virtual method 'java.lang.Class java.lang.Object.getClass()' on a null object reference]

Version tested:
0.68.2
0.69.1

reproduction in a bare new react native project, created with npx react-native init notifications --template react-native-template-typescript:

import notifee, {
  AndroidBadgeIconType,
  TimestampTrigger,
  TriggerType,
} from '@notifee/react-native';
import React from 'react';
import {SafeAreaView, Text, TouchableOpacity} from 'react-native';

export const testNotification = async () => {
  try {
    await notifee.requestPermission();
    const channelId = await notifee.createChannel({
      id: 'notification-channel',
      name: 'Reminder',
    });

    const fireDate = new Date();
    fireDate.setSeconds(fireDate.getSeconds() + 5);

    const trigger: TimestampTrigger = {
      type: TriggerType.TIMESTAMP,
      timestamp: fireDate.getTime(),
      alarmManager: {
        allowWhileIdle: true,
      },
    };

    await notifee.createTriggerNotification(
      {
        title: 'Test Notification',
        body: 'Hello',
        android: {
          channelId,
          badgeIconType: AndroidBadgeIconType.SMALL,
          pressAction: {
            id: 'default',
            launchActivity: 'default',
          },
        },
      },
      trigger,
    );
  } catch (e) {
    console.error(e);
  }
};

const App = () => {
  return (
    <SafeAreaView>
      <TouchableOpacity onPress={testNotification}>
        <Text>RUN</Text>
      </TouchableOpacity>
    </SafeAreaView>
  );
};

export default App;

The same issue is with react-native@0.67.4, but the issue is gone with the previous version on notifee (5.3.0).

Do you have the whole stack trace? This is not enough of it to be useful:

[Error: Attempt to invoke virtual method 'java.lang.Class java.lang.Object.getClass()' on a null object reference]

@mikehardy here is the stacktrace:

Well that is just bizarre, thanks for the report (great detail by the way), unfortunately the stack trace is a bit uninformative but that's not a complaint, it's just buried in the core library and that's how they look. @helenaford do you have any time for a local repro attempt? I'm travelling and will be for quite some weeks unfortunately. Failing that @alwex you can pull the repo and try to run the core library from source, it's not super hard though a bit subtle. This kind of bug is usually pretty easy to catch with source available though

[alwex]

I just tried to downgrade to v5.3.0 as @dancixx mentioned and the error is gone. It seems to have been introduced with v5.4.0, so not related with react native. I will try to run the code from source and see what happens.

[helenaford]

Thanks All, I will look now and find the issue 🙌

[helenaford]

Published a fix (v5.4.1), thanks for reporting this! Also, sorry you faced the bug, please let us know if you run into anything else. thanks!

[alwex]

I confirm the issue is resolved, thank you
