Android Question Health Connect Wrapper

[Katja]

Hi everyone,

I am currently working on a B4A wrapper for the Android Health Connect SDK. I am developing the wrapper in Android Studio (Kotlin) and my goal is to produce two JAR files:
1.StepCounterHC.jar (the wrapper classes)
2.stepcounterhc_dependencies.jar (all merged dependencies like Health Connect, Protobuf, and Guava).

When I compile in B4A, I get the following Dex error:

Error in C:\Android\tools\..\extras\b4a_local\unpacked-com.google.guava-guava-63914864012000\dex_v1\com.google.guava-guava.zip:classes.dex:
Type com.google.common.base.Function is defined multiple times: C:\Android\tools\..\extras\b4a_local\unpacked-com.google.guava-guava-63914864012000\dex_v1\com.google.guava-guava.zip:classes.dex, C:\Android\tools\..\extras\b4a_local\unpacked-stepcounterhc_dependencies-63922555505069\dex_v1\stepcounterhc_dependencies.zip:classes.dex

If I exclude guava from stepcounterhc_dependecies.jar I get a runtime error ClassNotFound: Settablefuture (which is from guava). When I search for com.google.guava-guava at runtime, its not found at all but its in the list of dexed files.

I am at a loss here, any help is highly appreciated. Thanks.

Don't embed Guava inside your jar.

Can you upload the xml + jar (without Guava)?

Hi,

I attached the xml and jar with the methods. The stepcounterhc_dependecies.jar (without guava) is too large, here´s a link for the download:
In my B4A Code I use:

        hc.Initialize("hc")
        Log("hc: " &hc)
        Dim available As Boolean = hc.IsAvailable(GetContext)
        
        Log("Health Connect Available: " & available)
        
        If available Then
                   
            Log("get daily steps")
            Try
                hc.GetDailySteps(GetContext, "2023-10-27")
            Catch
                
                Log(LastException)
            End Try
            
        Else
            Log("Health Connect is not installed or supported on this device.")
        End If

This is from The B4A Log:

Seems B4A is missing this in guava and its needed by Health Connect: failureaccess-1.0.2.jar. I added it via #AdditionalJar and also kotlinx-coroutines-guava-1.8.1.jar. Now the errors are gone.
