Unable write file

[JayGuo921 (Jay Guo)]

I made a application that need to save files on user’s phone, but I find that after recently update, every time when I try to save a file, it will return Error 2103/2104.

I have check whether it have no permission, but it still not work. I can sure my block have no bug.

I have a old app which created by elder kodular version, it can save file.

So, why my new app can’t save file?

1: have you allowed storage permission?
2: try simple name test.txt, without /

Finally I have find what the problem is. It is my phone’s problem, but I think every Xiaomi phones which use Android 10 will have this bug.

No, this won’t work on any device with Android version > API 22 (since Android 6, runtime permissions).
It’s not a bug and has nothing to do with Android 10.

As I posted several times, the File component does not ask for WRITE_EXTERNAL_STORAGE permission automatically (if you save a file). You MUST ask for it manually:

Note @Kodular:
But of course: the File component should automatically request WRITE permission.

File path for unzip file component

It’s really hard to get it working, because there are several issues with the File component: Sometimes the full path and sometimes the relative is used (see blocks below) WRITE permission is not queried automatically (only READ), so you have to ask manually for WRITE permission. Permission granted is not triggered when the app starts for the first time, so you have to reload the screen. Moreover: the File component can not access the assets with the APK (works only with companion). To chec…

Don't mention @KodularCreator

We have seen many users mentioning @KodularCreator… Do NOT do it! @KodularCreator is just a bot, we don’t use that account or login into it. All mentions sent to him just go to a “black hole” and they are never read Instead, you can mention @Kodular, which is the staff group, and we will get notifications

thanks, changed it

We will take a look into that

Emmm. Although the file component does not ask for permission by itself, but I still think it is Xiaomi’s problem. After I upgraded to Android 9, it will have two permission control interface,l.
One like this

And another like this

For every app, Only the second control interface can really change the app’s permission.
I had reported this bug to Xiaomi, maybe they will solve it soon.

I don’t understand what you are trying to say.
Please temporarily change the language of your device to English and post the screenshots again.

I also have some Xiaomi test devices with Android 9. So post the apk or aia to reproduce this behavior (which one?).

[JayGuo921 (Jay Guo)]

No I won’t. This problem had been solved

This problem had been solved

Yes, and exactly in the way that I showed above.
