Android Question HttpJob problem

[cwt]

Below is my code for POSTing to an API

    Dim j As HttpJob
    j.Initialize("", Me)
    j.GetRequest.SetContentType("text/xml")
    j.PostString(Main.ServerURL,PostString)
    Wait For (j) JobDone(j As HttpJob)
    If j.Success Then
        xml_parser.Initialize
        xml_parser.Parse(j.GetInputStream, "Parser")
    Else
        xui.MsgboxAsync("Server Connection Error: " & j.ErrorMessage , "Error")
    End If
    j.Release

This code works perfectly for me in B4i but not in B4A. I get the below runtime error message:

java.lang.RuntimeException: Only Post / Put requests support this method.

The error points to this line: j.GetRequest.SetContentType("text/xml")

What do I need to change? Thanks.

You should first call PostString and only then modify the request.

Explained here: Set HTTP Request Header with OkHttpUtils2

I actually did have the correct order in the code. I switched to OkHttpUtils2 from HttpUtils2 and it fixed it.

Still have problems.

If I use the Http andHttpUtils2 libraries I get this error message, which crashes the app on runtime:

java.lang.NoClassDefFoundError: Failed resolution of: Lorg/apache/http/client/methods/HttpPost; - I am trying to connect to an SSL server but I have added HU2_ACCEPTALL to Build Configurations Conditional Symbols.

If I use the OkHttpUtils2 libraries I get this error message on larger downloads from the server, which does not crash the app:

java.ioEOFException: source exhaused prematurely

The old HttpUtils2 is not relevant any more.

You can download files of any size with OkHttpUtils2. The problem is somewhere else...

For anyone out there who is getting this error while downloading from an API:

java.ioEOFException: source exhaused prematurely

This is normally caused by a compression-decompression issue and can usually be fixed with adding the header line shown below:

j.GetRequest.SetHeader("Accept-Encoding","identity")

    Dim j As HttpJob
    j.Initialize("", Me)
    j.PostString(Main.ServerURL,PostString)
    j.GetRequest.SetContentType("text/xml")
    j.GetRequest.SetHeader("Accept-Encoding","identity")
    Wait For (j) JobDone(j As HttpJob)
    If j.Success Then
        'parse your data here
    Else
       'error message here
    End If
    j.Release

This is less than a rare problem with OkHttpUtils2 - if you write your own server-side APIs as I do then it is not too hard to track down but if you rely on someone else for the server APIs this can be a killer problem.
