Additional context
At first glance when you search via google this seems to be a bug in flutter itself
flutter/flutter#64458
but the fix is already on master and as you can see, i still run into this issue.
everything works fine as long as the app is still running and a backround task is triggered. only the headless one crashes with above error.

The text was updated successfully, but these errors were encountered:

kanczler · 2020-10-21T09:15:50Z

I'm having the same issue. On my own device (Huawei P30 Pro), there are no problems, headless tasks run just fine, but on an android 7.1.1 emulator and several other devices whenever the headless task is triggered, the application crashes with the exact same exception.

I have just used flutter create foo to create a fresh new Hello World app. with flutter doctor:

I cannot reproduce this. How old is your app? You might have old code in your app from a previously generated flutter app that hasn't been properly upgraded.

KorbinianMossandl · 2020-10-21T14:57:08Z

yes, our app is about 1 year old, be we regularly maintain it, especially updates to flutter and the project structure.
the problem has only recently started with our latest release which made a switch from flutter 1.12 to 1.22.0.
Also as @kanczler mentioned it does not happen on every device.
Any ideas what this could be causing and why it only happens with flutter 1.22.0+ are greatly appreciated.
Will play around with the example project in the mean time and see if i can repdroduce.

christocracy · 2020-10-21T15:23:34Z

If your app was generated quite a long time ago, I suggest using flutter create to generate a fresh new app and migrate your /lib code into the new app and migrate your dependencies into the fresh pubspec.yaml.

KorbinianMossandl · 2020-10-21T15:34:36Z

not an option. we made so many customizations to the project structure for flavors and such. it would take forever to get everything to this point again.

christocracy · 2020-10-21T15:38:55Z

Then I suggest you flutter create foo and observe the difference between key android files, such as:

android/build.gradle
android/settings.gradle
android/app/build.gradle

You will want to migrate changes into your app.

Are you using a custom Application.java / Application.kt? If so, post it.

christocracy · 2020-10-21T15:39:17Z

we made so many customizations to the project structure for flavors and such

This is not hard to migrate.

KorbinianMossandl · 2020-10-21T15:55:30Z

android/build.gradle

android/settings.gradle

android/app/build.gradle

You will want to migrate changes into your app.

Are you using a custom Application.java / Application.kt? If so, post it.

we don't use a custom application.kt
but i will try to spot any differences between a fresh project and ours. that is the best lead so far.
will update with the results.

christocracy · 2020-10-21T16:04:57Z

I made a mistake in the files to check. Corrected above (ie: android/app/build.gradle)

KorbinianMossandl · 2020-10-22T16:43:09Z

ok, i looked at all the files, made changes so everything is exactly like in a newly created project, but the issue still exists.

but what i did is take our current project and move back to flutter 1.20.0 and the issue is completely gone.
so something in flutter 1.22.x broke/changed something that is causing the issues with background_fetch headless tasks.

it would be greatly appreciated if you could take another look.

christocracy · 2020-10-22T17:05:52Z

I have just created a fresh new Hello World app flutter create foo.

The app boots fine and simulated fetch events respond when app is running and headless.

KorbinianMossandl · 2020-10-22T17:07:59Z

i did the same and i know that it is working if you do it like this. but maybe flavors are the problem? All i can tell you is that the exact same code works flawless with flutter 1.20.0 but crashes with flutter 1.22.2 and that my android project looks like a newly created project just with all the necessary adaptions we need to make.

christocracy · 2020-10-22T17:13:46Z

The last reference to background_fetch in your stacktrace is HeadlessTask.java:128

at io.flutter.embedding.engine.loader.FlutterLoader.findAppBundlePath(FlutterLoader.java:324)
        at io.flutter.view.FlutterMain.findAppBundlePath(FlutterMain.java:97)
        at com.transistorsoft.flutter.backgroundfetch.HeadlessTask.startBackgroundIsolate(HeadlessTask.java:128

KorbinianMossandl · 2020-10-22T17:17:55Z

yes, as i said. only headless crashes. non headless works perfectly fine

KorbinianMossandl · 2020-10-22T17:18:41Z

i will try to reduce our project to a minimal example and share it with you, if that is ok?

christocracy · 2020-10-22T17:27:02Z

It seems this whole FlutterMain class has been marked @deprecated.

The docs say "Replaced by FlutterLoader":

Ok, try this.

In Android Studio, open your_flutter_app/android
Edit HeadlessTask.java in background_fetch module.
Modify line 128 to:

String appBundlePath =  FlutterInjector.instance().flutterLoader().findAppBundlePath();

KorbinianMossandl · 2020-10-22T17:49:36Z

then i get this error when trying to run:

KorbinianMossandl · 2020-10-22T17:50:14Z

missing import?

christocracy · 2020-10-22T17:54:29Z

Did you open your /android app in Android Studio?

When you add that line, the IDE will prompt you to add the required import io.flutter.FlutterInjector. On a mac, pressing [option]+[enter] will automatically add the required import.

Add the following import to the top of HeadlessTask.java:

import io.flutter.FlutterInjector;

KorbinianMossandl · 2020-10-22T18:01:33Z

still the same error :-/

christocracy · 2020-10-22T18:03:30Z

I don’t know. You must be doing it wrong.

Are you operating upon the /android app in Android Studio (not your flutter app)?

KorbinianMossandl · 2020-10-22T18:05:35Z

KorbinianMossandl · 2020-10-22T18:07:47Z

with same error i meant that i get the same error when i run a headlessTask

the compile worked
sorry if that was not clear.

KorbinianMossandl · 2020-10-23T09:38:23Z

i think falvors are the problem. i stripped everything from our project except flavors and use your example code for the main()
and still get the error for headless tasks. i need to to take another look at the project later on, just to make sure i stripped anything confidential. after that i will share with you, if that is ok?

christocracy · 2020-10-23T13:46:34Z

and use your example code for the main() and still get the error for headless tasks

Dart code is not responsible for your problem.

after that i will share with you, if that is ok?

That's fine.

KorbinianMossandl · 2020-10-26T17:10:26Z

@christocracy ok, after some more tinkering i found the solution:
for what ever reasons with flutter 1.22.x you need an Application.kt/java for headless to work. it can just be a basic file with

package com.package.name

import io.flutter.app.FlutterApplication

class Application : FlutterApplication() {
    override fun onCreate() {
        super.onCreate()
    }
}

and the corresponding line
android:name=".Application"
in the manifest.

without that it will not work even though it should not be needed and was not needed when running flutter 1.20.x

christocracy · 2020-10-26T23:39:41Z

And before you provided an override, your AndroidManifest contained this?

<application
        android:name="io.flutter.app.FlutterApplication"

KorbinianMossandl · 2020-10-27T11:53:16Z

that seems to work as well. before we had no android:name under <application/> because according to the migration guide (https://github.com/flutter/flutter/wiki/Upgrading-pre-1.12-Android-projects) it is not needed and should be removed.
but it seems it needs to be there for headless background fetch to work with flutter 1.22.x

christocracy · 2020-10-27T12:22:23Z

Generate a fresh new flutter create foo. Observe the AndroidManifest.xml.

This is what your application element must look like when no override is provided:

<application
        android:name="io.flutter.app.FlutterApplication"

KorbinianMossandl · 2020-10-27T13:03:06Z

@christocracy
this is directly from the flutter upgrade guide:

Since you link to it in your own setup guide and say

If you've upgraded your Flutter SDK to 1.12 (or higher) AND Upgraded Your Android Project, there are no additional steps required — everything is now automatic.

you might want to add the info above.

ghost · 2020-11-19T08:41:47Z

@christocracy ok, after some more tinkering i found the solution:

This is solve my problem.
Actually its not only in background_fetch its also happen in flutter_alarm_manager, the same issue is happening.

KorbinianMossandl · 2020-11-19T09:34:57Z

ok, so it seems to be a framework issue.
@christocracy i think you really should update the setup guide for Android and mention this workaround. if one follows your setup guide 1:1 he is bound to run into this issue.

apaolino · 2020-11-26T18:44:01Z

Had same problem and the provided solution resolved (Flutter 1.22.4).
I'm using embedding v2

darek-dots · 2020-12-28T10:35:50Z

In HeadlessTask.java I have changed:

       String appBundlePath = FlutterMain.findAppBundlePath();

to

      FlutterInjector.instance().flutterLoader().startInitialization(mContext);
      String appBundlePath = FlutterInjector.instance().flutterLoader().findAppBundlePath();

and it solved the problem of
java.lang.NullPointerException: Attempt to read from field 'java.lang.String io.flutter.embedding.engine.loader.FlutterApplicationInfo.flutterAssetsDir' on a null object reference at io.flutter.embedding.engine.loader.FlutterLoader.findAppBundlePath(FlutterLoader.java:324) at io.flutter.view.FlutterMain.findAppBundlePath(FlutterMain.java:98)

My AndroidManifest.xml does not have 'android:name' , as described in flutter upgrade guide.

...
According to https://api.flutter.dev/javadoc/io/flutter/embedding/engine/loader/FlutterLoader.html#startInitialization-android.content.Context-

Calling this method multiple times has no effect.

so it should be safe.

vishnukvmd · 2021-01-13T16:09:54Z

@christocracy
this is directly from the flutter upgrade guide:

Not following this step during the migration fixed the issue with headless tasks.

I had the same problem with flutter_alarm_manager when app was killed and flutter_alarm_manager wanted to fire an alarm, this solved the problem.

Generate a fresh new flutter create foo. Observe the AndroidManifest.xml.

This is what your application element must look like when no override is provided:
<application
        android:name="io.flutter.app.FlutterApplication"

This works on "Flutter 1.26.0-1.0.pre" for me.
Just included android:name="io.flutter.app.FlutterApplication" as @christocracy mentioned. Don't need any other changes

voivoed · 2021-01-25T18:46:20Z

This works on "Flutter 1.26.0-1.0.pre" for me.
Just included android:name="io.flutter.app.FlutterApplication" as @christocracy mentioned. Don't need any other changes

Can confirm that this worked for me also, using Flutter 1.25.0-8.3.pre.

vanlooverenkoen · 2022-08-31T14:46:48Z

I am still having this issue with flutter 3.3.0 Anybody an idea why the flutterapplication is still needed. while the old migration page said to remove it?

christocracy · 2022-09-02T13:28:22Z

Where in the Setup or API docs are you directed to use FlutterApplication?

khanhtruongq · 2022-09-08T07:12:57Z

please help, we got the same issue on 3.3.0

christocracy · 2022-09-08T13:27:20Z

I just booted the /example app in this repo. I have see no issues.

I suggest you implement the plugin in a fresh new hello_world app and familiarize yourself with the plugin Setup in a simple test-case, isolated from your application code.
