android_long_task's Issues

FlutterMain deprecated in AppService.kt

Hi, for future versions I think you should replace:

FlutterMain.startInitialization(this)
FlutterMain.ensureInitializationComplete(this, emptyArray<String>()) 

by

val loader = FlutterInjector.instance().flutterLoader()
loader.startInitialization(this)
loader.ensureInitializationComplete(this, emptyArray<String>())

in runDartFunction. See https://stackoverflow.com/questions/56339637/is-there-a-way-to-access-flutter-resources-from-native-code

Service notification not visible on Android 13(API level 33)

Hi, thanks for your great service. I have been used it on 2 applications already and now planning on 3th one :) .
While developing a POC on the 3th one noticed that the notification for the service is not visible on the Pixel 6 phone that runs on android 13. Quick check in the documentation shows that there are some new restrictions :
https://developer.android.com/guide/components/foreground-services#notification-immediate

I think a quick fix will be to add a button on the notification that should show the notification. Maybe that button could be to stop the service, which will be great user experience(if we can handle that click on flutter side, do our final work and stop the service).

For now my quick solution is to build against API 32, in that case shows the notification even on the PIxel

With flutter 2.2.3 your example doen't work

I'm trying to run your example with flutter 2.2.3 and I'm getting this error message:E/flutter ( 7230): [ERROR:flutter/lib/ui/ui_dart_state.cc(199)] Unhandled Exception: type 'Null' is not a subtype of type 'Map<String, dynamic>'

serviceMain stops when the device screen is off

serviceMain does not close but stops when the device screen is off, once you turn on the screen, the service continues to run without problems. I need the service to keep running when the screen is off. How can I achieve this?

Is there is way to set custom icon for foreground task notification?

Hi, I always get flutter icon even if I replaced with my own it with flutter launcher plugin. What can I do?

Stop service when app killed

How to stop the service when app is killed or exited? I successfully initialized the service, it's working fine when I minimize app. But it still working when I exit app and I want to stop it when I exit the app. Please help me.

Even using annotate @pragma('vm:entry-point') code does not work in release mode.

I got an issue in the release mode APK. I am implementing some code in the serviceMain function. It works fine in debug mode, but when I am building apk as release mode. The code was not working.

I found some issues in flutter flutter/flutter#91841

Using flutter_blue together with android-long-task leads to a PlatformException

Hey @easazade ,

I'm trying to use your package to download files from a BLE device in the background. It runs fine so far. However, I receive the following exception when I try to run any function from flutter_blue https://pub.dev/packages/flutter_blue

As soon as I try to run my initialization function for the BLEManager

Future<bool> asyncInit() async {
   flutterBlue = FlutterBlue.instance;
   await flutterBlue.stopScan();
   for (var device in await flutterBlue.connectedDevices) {
     await device.disconnect();
   }
   return true;
 }

I get the following exception:

E/flutter (11319): [ERROR:flutter/lib/ui/ui_dart_state.cc(199)] Unhandled Exception: MissingPluginException(No implementation found for method isAvailable on channel plugins.pauldemarco.com/flutter_blue/methods)
E/flutter (11319): #0 MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:175:7)
E/flutter (11319):
E/flutter (11319): #.1 FlutterBlue._setLogLevelIfAvailable (package:flutter_blue/src/flutter_blue.dart:78:9)
E/flutter (11319):
E/flutter (11319):

Any idea what's going wrong?

best regards and thanks for the nice plugin!

Detect the service is started

In general we can use AppClient.getData() from the app and see latest status.
Is it possible to query the AppClient and check if the service is running?

The problem is that if the code in the service callback has a problem and can not complete correct and update the status, then every time when you check from the app you will have a status that indicates running process.

For example if we have 3 statuses (UploadImages, UploadingImages and Idle). We want to start our service and upload the images only if current status is Idle. Then we send UploadImages to our service, the service starts uploading and changes it's status to UploadingImages. At this time there could be a problem and the service may stop here, then next time when you getData from the service will receive UploadingImages. Currently this status will remain until the app is force stopped and started again, then we will have null as response.

I'm surrounding my code with try catch and trying to close the service properly if something unpredictable happens, but still if is possible from the AppClient to check if the service is running will be great

Dart Unhandled Exception: NoSuchMethodError: No top-level getter 'serviceMain' declared.

Hello

Running the example with flutter run --release gives this error

E/flutter (14495): [ERROR:flutter/shell/common/shell.cc(94)] Dart Unhandled Exception: NoSuchMethodError: No top-level getter 'serviceMain' declared.
E/flutter (14495): Receiver: top-level
E/flutter (14495): Tried calling: serviceMain, stack trace: #0      NoSuchMethodError._throwNew (dart:core-patch/errors_patch.dart:218)
E/flutter (14495): 
E/flutter (14495): [ERROR:flutter/runtime/dart_isolate.cc(707)] Could not resolve main entrypoint function.

E/flutter (14495): [ERROR:flutter/shell/common/shell.cc(574)] Could not launch engine with configuration.

The code only works in debug mode.
This is very weird, the code worked well a few weeks ago. It seems to be an issue related to Flutter
flutter/flutter#91841
I don't know how to fix the issue, which is a severe regression.

Could you confirm the issue please? and help me to find a workaround.

Thanks

Flutter 3.13.9 Old Kotlin version breaks build process

Hi,

i received the following error in my Flutter 3.13.9 project:

The Android Gradle plugin supports only Kotlin Gradle plugin version 1.5.20 and higher.
The following dependencies do not satisfy the required version:
project ':android_long_task' -> org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.50

I fixed the Error by adjusting the Kotlin Version. I will submit a PR :).
In the meantime, if anyone suffers from this error, you might be able to get around this by using the following in your pubspec.yaml file:

  android_long_task:
    git:
      url: 'https://github.com/robinduerhager/android_long_task.git'
      ref: '3f90808ff72e6bead9b77de4655f9439c4b82482'

Add autostart?

I'm looking at your project to see if it can replace the unreliable WorkManager/AlarmManager for me.

One of the things I need is that my foreground service will be started automatically on a device reboot, or if the foreground service is stopped for any reason other than explicit user command.

I'm afraid I have have no idea where to start with these. Roberto has some suggestions in a similar project he wrote up at https://robertohuertas.com/2019/06/29/android_foreground_services/ (at "Bonus" and "Bonus 2" but his code seems totally different to your own.

How might I go about adding that functionally to your project?
