BUG change status when loading is complete, API 28 (android 9)

I am attaching the logs

On API 29-33 works correctly

you need to ask for WRITE_EXTERNAL_STORAGE permission

[DmitriySimonov]

you need to ask for WRITE_EXTERNAL_STORAGE permission

It did not help

I am use

        compileSdkVersion = 34
        targetSdkVersion = 34

even if I add these lines to the manifest, nothing will change

    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    ....
    android:requestLegacyExternalStorage="true"

https://developer.android.com/about/versions/11/privacy/storage
Target Android 11

If your app targets Android 11, both the WRITE_EXTERNAL_STORAGE permission and the WRITE_MEDIA_STORAGE privileged permission no longer provide any additional access.

Keep in mind that, on devices that run Android 10 (API level 29) or higher, your app can contribute to well-defined media collections such as MediaStore.Downloads without requesting any storage-related permissions. Learn more about how to request only the necessary permissions when working with media files in your app.

[qwertylolman]

did you request the permission? writing permission in manifest is not enough. also, check that permission is granted in app settings.

[DmitriySimonov]

I don't need permission because I'm saving the file to my phone's internal memory
NOT ExternalStorage

[qwertylolman]

could you show the FlutterDownloader.enqueue method call and passed arguments?

[DmitriySimonov]

On api 29 I tried different installation paths, but the error persists

 String path = await NetworkUtils.generateFullPath(
      path: '/update/apk',
      api: NetworkEngine.MOBILE_API,
      serverService: _serverService,
    );

    String? accessToken = await _authenticationService.getAccessToken();
    if (accessToken == null || accessToken.isEmpty) {
      throw ('accessToken is null');
    }

    try {
      final IFileUpdateManager fileUpdateManager = FileUpdateManager();
      final String saveDir = await fileUpdateManager.directoryPath();
      final String fileName = fileUpdateManager.getFileName(version);

      final String? result = await FlutterDownloader.enqueue(
        url: path,
        //url: 'https://speed.hetzner.de/100MB.bin', // для отладки
        headers: {
          HttpHeaders.authorizationHeader: NetworkEngine.BEARER + accessToken,
        },
        savedDir: saveDir,
        showNotification: true,
        fileName: fileName,
        openFileFromNotification: true,
      );
      return result;
    } catch (e) {
      rethrow;
    }


  Future<String> directoryPath() async {
    final Directory? dir = await getExternalStorageDirectory();
    if (dir == null) {
      FLog.error(text: 'Нет директории getExternalStorageDirectory!, вернем пустую строку');
      return '';
    }

    final Directory dirUpdate = Directory('${dir.path}/update');
    dirUpdate.createSync();
    return dirUpdate.path;
  }

@DmitriySimonov yes the package having this issue sometimes. As of now, call your function if(progress == 100).
You have to call your function in status completed also since progress == 100 won't work sometimes. Call the function in both conditions.
Note that It's a temporary solution.

When will this bug be fixed?

[wengxianxun]

@DmitriySimonov是的，有时软件包会出现此问题。现在，调用您的函数 if(progress == 100)。 您还必须在已完成状态下调用函数，因为进度== 100有时不起作用。在两种情况下调用该函数。 请注意，这是一个临时解决方案。
