Cannot use libsodium

[maerlynflagg]

i import the package and i do before any encryption call i do

Sodium.init();

but on some devices there came a exception:

dlopen failed: library "libsodium.so" not found

Screen of user:


is it a bug? or did i miss something?

do you have any idea, what the problem is?

Doesnt look good, couple of questions:

• what version of flutter and flutter_sodium are you using?
• can you be more specific on the devices where flutter_sodium fails?

This is not necessarily related to specific devices, but could also be related to culture/language settings. If you can share as much info as possible, that would be great.

Thanks.

this issue hasn't every user. so i thought it's device specific. but currently i haven't details from the users device.

flutter_sodium version:

flutter_sodium: ^0.1.10

flutter doctor -v:

I got some device infos:

• HTC device
• language setting is german like a lot of our users
• Android 6 is the current OS

[kozw]

There might be an issue with Android 6 and older versions, as described in https://github.com/flutter/flutter/issues/73318.

Looks like there is a possible workaround, that you'll need to apply in your Android's App java code. See https://github.com/flutter/flutter/issues/73318#issuecomment-754598119

[maerlynflagg]

okay, thanks. workaround looks simple.

@kozw I'm running into the same issue on a few devices that I unfortunately do not have access to.

https://github.com/flutter/flutter/issues/73318#issuecomment-754598119 suggests two work-arounds.

My settings.gradle already resembles the first work-around, so there's nothing to change there.

As for the second, it looks to me like it's supposed to be part of the plugin's Java code? https://github.com/firstfloorsoftware/flutter_sodium/pull/63 perhaps?

[vishnukvmd]

63 triggers https://github.com/flutter/flutter/issues/83613, so closing that.

@kozw @maerlynflagg Could you please tell me to where I'm supposed to add this workaround? Is there sample code I can draw inspiration from? Thank you!
