Android Question Target SDK 28/29 NoClassDefFound

[MotoMusher]

This was (and is) fine under target=27. I need to publish an update and Play is forcing SDK 29 now.

When I open one of my activities (others are fine), I get the following:

JobName = jobAuth, Success = true
** Activity (main) Pause, UserClosed = false **
java.lang.NoClassDefFoundError: Failed resolution of: Lorg/apache/http/impl/client/DefaultHttpClient;

...
Caused by: java.lang.ClassNotFoundException: org.apache.http.impl.client.DefaultHttpClient


Any ideas on how to resolve? I'll post updates as I find them. When I switch manifest back to 27 it works just fine.

android.jar / targetSdkVersion / minSdkVersion

Are you using the old HttpUtils2 library? Switch to OkHttpUtils2.

I appear to have/had a couple issues. I haven't changed SDK in a while.

Android.jar was pointing to sdk27. I moved that to 29 in paths configuration

I was using the httputils service from long ago as a file in my project. I pulled the httpjob and httputilsservice from the project (just renamed for now) and replaced with references to OK.

Most validates now, but I had made heavy use of PutFile in httpjob

What's the recommended workaround for that in OK?

Public Sub PutFile(Link As String, Dir As String, FileName As String)
    Dim length As Int
    If Dir = File.DirAssets Then
        Log("Cannot send files from the assets folder.")
        Return
    End If
    length = File.Size(Dir, FileName)
    Dim In As InputStream
    In = File.OpenInput(Dir, FileName)
    req.InitializePut(Link, In, length)
    CallSubDelayed2(HttpUtils2Service, "SubmitJob", Me)   
End Sub

If POST is also fine then use Job.PostFile.

If the file is not too large then you can use Job.PostBytes with File.ReadBytes.
