Issue: When a notification is sent while the application is in the foreground, it crashes with the android.os.MessageQueue.nativePollOnce (Native method) error. There is no issue with the first notification; it arrives promptly. However, subsequent notifications experience delays. After a while, all pending notifications arrive simultaneously, leading to a crash of the application.

packages: firebase_core: ^2.30.0 firebase_messaging: ^14.8.2

Reproducing the issue

1-) Launch the application on an Android device. 2-) Send multiple push notifications to the device within a short period. 3-) Notice the delay in receiving subsequent notifications. 4-) After some time, observe all pending notifications being delivered simultaneously, leading to a crash of the application.

Firebase Core version

Hello @kdrgrgn,

Could you please try out the Flutter example app available at this link? Configure it with your Firebase backend using the FlutterFire CLI, which you can find here. After setting it up, could you let us know if the issue still occurs? Thanks!

[kdrgrgn]

Helo @TarekkMA We applied the example in the link. The same issue is happening there too, only on Android. The first message works fine. Then the subsequent messages come in bulk, and despite not setting the default message, the rest of the messages fall into background messaging while the app is open. Then a crash occurs.

[TarekkMA]

Could you please provide details on the payload you are using with firebase-admin, as well as the method you are employing to send these messages? This information will help us reproduce and diagnose the issue effectively. Thank you!

[kdrgrgn]

@TarekkMA I can't share the structure I normally use with you. However, I'm experiencing the same issue even when I push with Postman

[TarekkMA]

@kdrgrgn, Can you use firebase-admin and see if this still causes issue as well?

An example script can be as follows:

// 0. install firebase-admin via npm
var admin = require('firebase-admin');
// 1. Download a service account key (JSON file) from your Firebase console and add to the example/scripts directory
var serviceAccount = require('./key.json');
admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
});

// 2. Copy the token for your device that is printed in the console on app start (`flutter run`) for the FirebaseMessaging example
const androidToken = 'token here';

// 3. From your terminal run `npm install`.
// 4. Run the script using node and your app will receive messages in any state; foreground, background, terminated.
// If you find your messages have stopped arriving, it is extremely likely they are being throttled by the platform. iOS in particular
// are aggressive with their throttling policy.
admin
  .messaging()
  .send(
    {
      token: androidToken,
      data: {
        foo: 'bar',
        float: '12034'
      },
      notification: {
        title: 'A great title',
        body: 'Great content',
      },
      android: {
        // Required for background/terminated app state messages on Android
        priority: 'high',
      },
      apns: {
        payload: {
          aps: {
            // Required for background/terminated app state messages on iOS
            contentAvailable: true,
          },
        },
      },
    },
  )
  .then((res) => {
    if (res.failureCount) {
      console.log('Failed', res.results[0].error);
    } else {
      console.log('Success');
    }
  })
  .catch((err) => {
    console.log('Error:', err);
  });

Hey @kdrgrgn. We need more information to resolve this issue but there hasn't been an update in 7 weekdays. I'm marking the issue as stale and if there are no new updates in the next 7 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!

[google-oss-bot]

Since there haven't been any recent updates here, I am going to close this issue.

@kdrgrgn if you're still experiencing this problem and want to continue the discussion just leave a comment here and we are happy to re-open this.

Hi,

We have the same anr problem in our project. Additionally, notifications are sent via "firebase-admin" as you mentioned.

This problem has increased a lot in the last 6-7 months and continues to cause a lot of anr. I am submitting the "Logs & Breadcrumbs" and "Stack trace" information I received from Firebase Crashlytics.

Number of anr received in the last 90 days (31K);

@Cengizhanerturan Hi, I couldn't solve the problem. I switched to Onesignal. It's working fine now
