I have a txt file in the project directory, and I can read it from the path res://myfile But when I run on an Android device, it check it with file_exists, it return false, am I miss some permissions?
Also, I can not read or write to file in user:// on Android. But it has no problem when run on iOS device.
On Android, when the app exit by press back exittree will not called, but I can do save work in notification by the notification NOTIFICATIONWMQUITREQUEST.
But the app was force exit, No NOTIFICATIONWMQUIT_REQUEST is received, and no way to save data.
It's very confusing.
Maybe I must save to disk for each change, but this is not good way,
No that is to be expected. Force close is a kill.
So IMHO always save your settings if there's a change wich is worth saving. (level completed, option saved etc.)
I do even rename the previous settings file as a backup (only once per startup) in case that the save-process gets interrupted by a force-close or other event (disk space full). Naturally I then also have to check for integrity when loading the settings on restart and switch to the backup settings file when encountering problems.
Before export to .apk, have you tried to include myfile.txt in the "Export"->"Resource" panel?
I have fix read myfile.txt by include *.txt.
But I still can not read or write the file user://settings.cfg for save my settings.
I use ConfigFile, it can work on Mac and iOS.
It is definitely possible to write files to user:// in Android. And it is possible to read files from user:// and res:// as long as they exist.
Naturally, to be able to read files in user:// you'd first have to create one on runtime (file will be persistent).
What is your code for reading/writing?
380/5000 I faced this problem too, so I stuck a lot until I did the following. 1- Change file directory to user: // 2-Copy and paste your txt file where is your project in "user", how to find? just go to C: \ Users \ Lara \ AppData \ Roaming \ Godot \ app_userdata \ ProjectName 3-Va on Export >>> Resource >>> Filters to export non-resource files: type * .txt Ready :3
