how to save in other storage folder in android?

mc 3,681

I am using .net MAUI and want to save the sqlite db to other folder.

I know I can get the FileSystem.AppDataDirectory and save the db but it will be deleted when I remove the APP.

how to keep the db when I remove the APP and when I reinstall it I can use this database?

What is your version of android Target-Framework?

After Android 11 or later, we cannot save files in the external storage directly, it is related to Storage updates in Android 11, this update comes from native android's design.

Could you request WRITE_EXTERNAL_STORAGE permission? If yes, note: the Google Play store has a policy that limits usage of this permission.

And you can request this WRITE_EXTERNAL_STORAGE permission by following code.

string package = AppInfo.Current.PackageName; var uri = Android.Net.Uri.Parse($"package:{package}"); Platform.CurrentActivity.StartActivityForResult(new Android.Content.Intent(Android.Provider.Settings.ActionManageAppAllFilesAccessPermission, uri), 10);
