saveDir didn't work

when i set savedDir=/storage/emulated/0/Android/data/vn.hunghd.example/files
but files save to /storage/emulated/0/Download/Android-Programming-Cookbook.pdf

• compileSdkVersion: 30
• android version: 11
• flutter_downloader: 1.7.0
• flutter version: 2.5.0

my code

  Future<String?> _findLocalPath() async {
    var externalStorageDirPath;
    if (Platform.isAndroid) {
      try {
        // externalStorageDirPath = await AndroidPathProvider.downloadsPath;
        externalStorageDirPath = (await getExternalStorageDirectory())?.path;  //<-----------here
      } catch (e) {
        final directory = await getExternalStorageDirectory();
        externalStorageDirPath = directory?.path;
      }
    } else if (Platform.isIOS) {
      externalStorageDirPath = (await getApplicationDocumentsDirectory()).absolute.path;
    }
    return externalStorageDirPath;
  }

Actually, we tried first on flutter 2.5 & flutter_downloader v1.7.0 and the error happened. Then we tried downgrading as I mentioned above in my comment. We end up rollback our app to flutter 2.2.1 and flutter_downloader v1.6.0 to make it works.

I’ll try to debug deeper and let you know about my findings on monday 🤞

There’s change on android storage management from Android 11. please upgrade to v1.7.0

I just tested on these specs and still got the same issue as mentioned above:

• android version: 9
• flutter_downloader: 1.7.0
• flutter version: 2.5.0

Even though it’s written DownloadWorker{url=https://storage.googleapis.com/vx_dev_tasks/tasks/710/INV2021015974 (1).pdf,filename=null,savedDir=/storage/emulated/0/Android/data/com.sunterra.vx.dev/files/Downloads,header=,isResume=false, the file is not exist on the savedDir. The file is downloaded to /storage/emulated/0/Download/INV2021015974 (1).pdf

I’m not using android 11, so upgrading to v1.7.0 won’t fix the problem.

Also happened to me on:

• android version: 9
• flutter_downloader: 1.6.0
• flutter version: 2.5.0

But, it was previously successful:

• android version: 9
• flutter_downloader: 1.6.0
• flutter version: 2.2.1

Maybe the culprit is flutter 2.5.0
