Java Question Skype For Business B4A Library

[yo3ggx]

Skype for Business SDK for Android is availabe for free from Microsoft:
https://msdn.microsoft.com/en-us/skype/appsdk/skypeappsdk

I'm trying to build a B4A library based on that SDK in Eclipse.
I was able to compile the examples directly in Android Studio, but building a library in Eclipse based on this seems to be a difficult job.
The SDK contains several aar Android libraries.
As described here:
https://www.b4x.com/android/forum/threads/android-library-format-aar.52116/
the aar libraries are complex archives.
I have tried to follow Erel advices from here:
https://www.b4x.com/android/forum/threads/import-library-aar-android-studio.60259/#post-380056
but the arr libs contains not only jar files (class.jar), but resources, JNI libs (.so files) and other java (jar) libraries.

Putting the so files in additional\armeabi fodler and importing all other jars (clasess and java libs) does not work.

Any other hints on how to go further?

Thank you.
Dan

My experience with Java is very limited.
I've made some progress on this, but not enough to have a functional library. I was able to create the library structure in Eclipse by:
- unzipping the aar libraries and using class.jar files as external libraries in my project (each one renamed using the name of the aar file)
- .so files from aar files moved to /additional/armeabi project subfolder
- jar libraries used by the aar files moved to /libs project subfolder
- using the ConversationHelper.java class in my project source
- creating a wrapper class (Skype4Business.java) with just some basic functionalities (sdk initialization and joining a S4B conference)

I've done the library compiling using Simple Library Compiler. The project does not give any error in Eclipse, or when compiling in B4A. The obtained jar file contain the .so files but not the libraries used by the previous aar files, so when I try to run it I get a missing class error.

You can find the B4A library files here:
https://www.yo3ggx.ro/s4b/s4b.zip
and the small B4A sample here:
https://www.yo3ggx.ro/s4b/b4a.zip

The error I get in B4A is:
java.lang.NoClassDefFoundError: Failed resolution of: Lcom/microsoft/office/sfb/appsdk/Application;

This is a class available in the library.

Any help is highly appreciated.

Thank you.

Some more progress.
I was able to remove this error adding the following line in the library:
@DependsOn(values={"SkypeForBusiness"})

Now there is an issue loading the native library.
java.lang.RuntimeException: Failed to load native library
at com.microsoft.office.sfb.appsdk.Application.LoadNativeLibrary(Application.java:94)

The line looks like the following:
System.loadLibrary("acomo");

The file libacomo.so is available in /additional/armeabi folder.

 

[DonManfred]

check the content of your generated jar with zip. Is the .so inside it?

 

[yo3ggx]

Yes, libacomo.so is in the armeabi subfolder of the jar archive.

I've moved the libacomo.so file in the library workspace from /additional/armeabi to /additional/lib/armeabi and now I don't get any error, but the application just exits when the library class initialization is done.

 

[DonManfred]

but the application just exits when the library class initialization is done.

check the unfiltered log if nothing appears in the normal log

 

[yo3ggx]

Unfortunately I'm now over the B4A Bridge and the unfiltered log shows nothing too. I will check later in the evening over USB.

 

[yo3ggx]

It seems that the crash comes from the first line where the SDK is initialized.
In the sample Android application (written in java under Android Studio), the initialization is done like that:

Application application = null;
this.application = Application.getInstance(this.getApplication().getApplicationContext());

In my initialization routine from the library wrapper I'm using:

public void Initialize(BA ba, String displayName,
            String meetingUrl){
  this.ba = ba;
  this.application = Application.getInstance(ba.activity.getApplicationContext());
  ...

Is this the right way to do it?

 

[DonManfred]

did you added a @ActivityObject() annotation to your wrapper-code?

 

[DonManfred]

maybe

this.application = BA.applicationContext;

?

 

[yo3ggx]

Added @ActivityObject() with the same result.

"Application" is a class from the SDK, not my application (see the code from the sample).

 

[DonManfred]

i´m at work as yet. Only browsing the forum from time to time... Not really time to look at something...

 

[yo3ggx]

Me too. I'm talking about the code in my message #8.
I will check later the log when possible to connect directly over USB.

When the activity is loaded, the Application class is initialized as follows:

Application application = null;
this.application = Application.getInstance(this.getApplication().getApplicationContext());

This one works, but I don't know how to implement the same in the wrapper.

 

[DonManfred]

The point is that you need the applicationcontext. The context of the running task.
Talking about a b4a which is running you need to get the applicationcontext from the b4a app i guess.

i would try the code i posted in #10 to see if this works...

 

[yo3ggx]

The problem with #10 is that "BA.applicationContext" is not an "Application" class required by "this.application", but a Context.

The closest for the library to the one that works in the example will be:

public void Initialize(BA ba, String displayName,
            String meetingUrl){
          

        this.ba = ba;
        this.application = Application.getInstance(ba.activity.getApplication().getApplicationContext());
.......      
       }

but still does not work.

 

[yo3ggx]

Update:
Connected over USB and still no error in the log. If I deselect Filter, I get several errors related ti this library.

This is an extract from the full log just before the application closes without any error in the IDE.

unable to resolve static field 2535 (app_name) in Lcom/microsoft/office/lync/api/R$string;
java.lang.NoClassDefFoundError: com.microsoft.office.lync.api.R$string

The corresponding jar library is libucmp.jar which doesn't seem to contain this class.

And then the error:
An error occurred:
(Line: 39) End Sub

Which is the end of the B4A routine containing SDK initialization.

Looks like you are missing resources for the lib...

 

[yo3ggx]

Can you detail a little bit? To what resources are you referring to?
I have attached the jar containing the package com.microsoft.office.lync

 

[DonManfred]

in the microsoft lib there is maybe a resourcefolder with layout, drawables and so on...
I guess you need to add this resource-folder in b4a too (#additionalres:...)

 

[yo3ggx]

I've added #AdditionalRes.." with the location where all resources from the aar files are stored.
I need to pass over this error:

As is to big to be attached here, the jar file containing com.microsoft.office.lync.tracing.Trace is available here:
https://www.yo3ggx.ro/s4b/platform.jar

The line with the error (from the decompiled jar file) is the following:
