SimpleFileBrowserCanvas(Clone) won't appear on Android

[grox777]

SimpleFileBrowserCanvas(Clone) does not open on Android. In Editor it works fine... Worked well in previous builds, I have no idea what was changed or what settings I might have accidentally broken.

• Write permission set to External (SdCard)
• Unity version: 2020.2.6f1
• Tested on Galaxy A30, android 11 and Bluestacks emulator

P.S. This was supposed to be the last test before publishing... But here we go again :'D

That's strange. Is there anything I need to know about your setup? Like, are you putting the file browser in your scenes manually or letting the system Instantiate the file browser canvas automatically as needed? Have you modified the plugin in any noticeable way? Can you put Debug.Log lines before and after the FileBrowser.ShowLoadDialog function in your script and verify that they are both logged to Android Logcat?

Thanks for reply!!

In my case file browser canvas instance created via script... No, i did not modified plugin... :^)

Im not sure about it...

• i am not so good at programming
• script was created about a year ago, and i just can't remember purpose for many things in it
• i have no expirience with Android Logcat, i feel like already heared about it, but never used

I'll try to do it tomorrow :^)

Please put a Debug.Log("Calling file browser"); line at the beginning of ShowLoadDialogCoroutine function. To see this log and other logs in logcat, you can install Unity's Android Logcat package via Package Manager. Check if "Calling file browser" is logged there and if there are any error message after that.

It was much easier than i thought, thank you!

Now we know, that for some reason unity throws "object reference not set" exception...

Can you select the SimpleFileBrowserCanvas prefab in Project window and check its Inspector to verify that all of its variables are assigned values?

Seems like all of them are assigned

Problem solved by disabling "Release" checkbox in "Minify" category. Player settings -> Publishing settings -> Release checkbox.

Oh.. That was an unexpected solution, honestly. I'll probably give it a try myself.
