Any workaround?

 

[drgottjr]

did you try typing "datastore" in the sdkmanager. looks like they're there ready to go
sorry; i misread the post. probably drunk again

 

[Pendrush]

1. Create empty project.
2. Add this line: #AdditionalJar: androidx.datastore:datastore

#Region  Project Attributes
    #ApplicationLabel: B4A Example
    #VersionCode: 1
    #VersionName:
    'SupportedOrientations possible values: unspecified, landscape or portrait.
    #SupportedOrientations: portrait
    #CanInstallToExternalStorage: False
    #AdditionalJar: androidx.datastore:datastore
#End Region

3. Install all needed dependencies reported by B4A.
4. You are unable to compile.

The problem: duplicated classes inside datastore dependencies.

.Actual_jvmKt is defined multiple times

I know what the problem is. I don't know how to resolve it.

 

[Erel]

I see it too. It looks like a multiplatform SDK which isn't handled properly by B4A toolchain. I don't see a workaround for now. Why do you need this SDK? You can use KeyValueStore

 

[Pendrush]

Datastore is dependencies for other lib.
I am trying to create a wrapper library that will be able to be used in B4A.

 

[Erel]

I was able to get it compiling by removing the jvm dependencies from the POM files.

The attached zip contains the folders that should be under <sdk>\extras\b4a_remote\androidx\datastore

It is possible that you will encounter an error at runtime. I haven't tested the actual functionality.
