Additional context

• For any permission requested the file_picker send to the audio record
• version 1.4.3+2 works fine

[miguelpruivo]

Hum, this is odd. How are you picking the file?

[gilvangobbato]

Hum, this is odd. How are you picking the file?

Maybe could be this the problem... In this case I'm using image_picker plugin

ImagePicker.pickImage( source: ImageSource.gallery, maxWidth: 1024, maxHeight: 1024, )

I'm changing to use only file_picker, maybe it will resolve, so, I can't use both

[gilvangobbato]

I've tried, and de error keep, I don't understand how is possible that it is opening a audio record?!?! It's strange

if I back to version 1.4.3+2 all is ok

[miguelpruivo]

@gilvangobbato you shouldn't have any issue using both. Actually, I recommend you to do so if you need to use camera or multi file gallery picking, for example.

However, you didn't answer my previous question: how are you using the FilePicker? Could you please post your code?

Thank you.

[gilvangobbato]

Thank you.

Woow, sorry, you are rigth! For example in this case

List<File> files =
        await FilePicker.getMultiFile(type: FileType.ANY, fileExtension: 'db');

or this

File file =
        await FilePicker.getFile(type: FileType.ANY, fileExtension: 'csv');

[miguelpruivo]

@gilvangobbato does this happen with Android, iOS or both?

[gilvangobbato]

@gilvangobbato does this happen with Android, iOS or both?

Android, I'm not using iOS yet.

[miguelpruivo]

Ok. I'll take a look. That's really odd anyway, I'm not sure if I'm going to be able to replicate it.

[hsalazarl]

I have the same issue here, I am using the FilePicker.getFile() method, like this:

return FloatingActionButton( onPressed: () async { var file = await FilePicker.getFile(); print(">>> ${file.path}"); } ); As you can see, I am calling it inside the onPressed of the FloatingActionButton. The file picker gets opened, and I can select a file, but it never returns the File and so the print() method never gets invoked.

I am using using Android 10 on an emulated device and Android 9 on a physical device.

[gilvangobbato]

Ok. I'll take a look. That's really odd anyway, I'm not sure if I'm going to be able to replicate it.

I'll try to build an application to help you

[gilvangobbato]

Ok. I'll take a look. That's really odd anyway, I'm not sure if I'm going to be able to replicate it.

So, I did and in the following example is possible to reproduce the error. https://github.com/gilvangobbato/file_demo.git

@hsalazarl this seems to not be related with this issue but something else. If your print clause never gets called that’s probably because an exception is being thrown somehow.

Wrap it with a try catch clause and let me know what it prints. Nevertheless, Android 10 requires legacy storage enabled on your manifest file or else won’t work (check this answer). I must add it to the wiki.

@gilvangobbato thank you! I’ll try to take a look ASAP and keep you updated.

[hsalazarl]

@miguelpruivo agreed. I think my specific problem has to do with navigation. Because when I select the file, the FilePicker goes away, and it does not return with the File. But if at that moment I click Stop on AndroidStudio, the app closes but reveals the FilePicker. That's why on a second attempt to use it, it says that it is still active.

[miguelpruivo]

@hsalazarl I recommend you to run the example provided with the plugin and see if it works fine for you. If it does, then you should recheck your app’s logic for picking the file and make sure you don’t trigger multiple picks at once, regardless of it being protected from the plugin anyway.

[giovanitrevisol]

I have the same problem

[miguelpruivo]

@gilvangobbato just noticed that your error is actually related to ImagePicker and not FilePicker.

@GiovaniTrevisol93 could you provide more details? The more we have, the better it gets to fix. Thanks!

Yes, the error is on ImagePicker, but if I back the FilePicker version to 1.4.3+2 all is ok. So what I mean is that probably has some interference each other. I didn't try to back ImagePicker version, but I can do it to see the reaction.

[miguelpruivo]

@gilvangobbato would you mind checking and trying the purposed on this answer on a similar issue with PermissionHandler plugin? Someone found a cause and a solution.

Thank you.

Thank you.

So, thank you, I did the steps, this error (PlatformException) stops, but it continues open audio record. I will ask for some help in that plugin.

Thanks

[miguelpruivo]

The audio is something that I must take a look on. As for the exception itself, I’ll make sure I add it on the documentation as well because this is not the first time someone comes across this. It looks like you need to migrate your app to be compatible with V2 embedding, that’s why.

Thank you.

[gilvangobbato]

Thank you.

[miguelpruivo]

@gilvangobbato just found what was causing your record audio issue when opening the picker, you are using FileType.any with csv custom extension. You must use FileType.custom when providing a custom extension.

However, it might be a good a idea for me to throw an exception when someone provides a custom format and selects other than FileType.custom to prevent this kind of scenarios.

Thank you!

Thank you for your help, but I think that the problem is my device, I tried but didn't solve. So, I've tested in other devices and it worked correctly and the issue is after request permisson and confirm, seriously, this is VERY strange, lol. I created an issue for permission_handler plugin to see if someone could help me.

But thanks for your attention.

I have two profiles on my phone: 1. personal profile and 2. work profile. The above-mentioned code works well in the personal profile, but when I try to run the same code in the work profile, it throws this error:

@miguelpruivo Sir, could you please tell me why I am getting this error in the work profile especially, and why I am unable to pick files from the storage?

Hey, I might be too late here, but is there any specific blockers that prevents to have multiple picks at once.
( I am picking a large file and while it is being loaded to cache, I am trying to pick a doc ).

I am facing Error in image picker: PlatformException(already_active, Image picker is already active, null, null) any solution ?
