Android release app crashes after image download

[nattesh]

Hi, I'm here to report a very particular issue. The library is awesome and it works as expected in iOS in any circumstance. Using Android everything is good running the debug version of the apk, but when I build the release version of the apk and try to download an image the app just crashes. Thing is: app crashes just after the download.

I'm using v2.3.2.

Here's the code snippet:

void _saveNetworkImage() async {
    _startDownloading();
    String path = widget.details.path;
    await GallerySaver.saveImage(path);
    _endDownloading();
  }

  void _startDownloading() {
    setState(() {
      downloading = true;
    });
  }

  void _endDownloading() {
    setState(() {
      downloading = false;
      done = true;
    });
  }

You may notice that there's nothing more than the download and two state updates that involve only two flags (just to handle a circular spinner showed during the download).

Tested on two different devices (OnePlus 7 and OnePlus 3), with stock rom and fully updated (if you're wondering about SELinux). Mind that the picture is actually saved, so if I check the picture in the gallery app I can see it and use it.

Any update over this issue ?

maybe you have not set permission to save photo to gallery. add this to ios/runner/info.plist <key>NSPhotoLibraryUsageDescription</key> <string>Photo Gallery Set Avatar</string>

you may need permission_handler plugin to check if have perssion to save photo.

Permission.storage.request().then((value)async { if(PermissionStatus.granted == value) { //your code } });

Thank you for your kind reply. As I said, permissions are set in fact the image is correctly saved on the device (and I can see it browsing the gallery once the app is crashed).

The same case happened to me also. Images are saving successfully but app kept crashing, I then figured out that it was because I was downloading media in bulk at the same time so I added delay in downloading the files and it stopped crashing my application.

For me, It shouldn't be the delay crashing the app. I am downloading on tap of a button and mostly one file at a time.
