Strange. This issue shouldn't be happening since it was fixed in 2019. Bug 1280184: Starting from Android M, the system download manager has started to delete downloaded files if the download is removed from the download manager again or if the downloading app is subsequently uninstalled, even if the files have been downloaded to a public folder on the shared storage. In Android O, this was changed to only clean up files in app-private directories and leave files e.g. in the public Downloads folder alone, but that fix only applies to files actually downloaded via the download manager. Files that are registered with the download manager after having been downloaded independently, as in our case, are still deleted unconditionally when the registering app is uninstalled. Additionally, starting from Android O Google has also started replacing the former user-facing part of the download manager, the Downloads app, with a new general file explorer-type app, whose "Downloads" view simply shows all files stored in the corresponding folder. Since that removes the only raison d'être of the downloads integration and we also don't want to delete user's downloads just because they're uninstalling us, we disable downloads integration again on all Android versions exhibiting this behaviour.
