Android Question [SOLVED] Program type already present: okio.AsyncTimeout$Watchdog

[foakgul]

Hello,

I've been using B4A since early releases for various projects. I updated to B4A v12.0 to recompile an old project of mine so that it conforms to latest Google Android guidelines.

Project was compiling fine on a previous version of B4A (non 64bit), using targetsdk of 29 or below but it had problems targeting api30 or api31, giving me "problem parsing package error".

When I switched to 64 bit version, now I'm getting the following error:

Dex merge Error
Error: Program type already present: okio.AsyncTimeout$Watchdog
Compilation failed

I'm using the same additional library folder as before which didn't complain. Here's a snapshot of libraries folder which includes okio. If I remove any of the okio jar files, compiler complains about not finding them.

Any suggestions are welcome

Thanks
Ferit

Any suggestions are welcome

Have you follow the instructions to update to v12.0?

You must download an updated Android SDK + additional resources, in order to use the new version.

Hi Jose,

Thanks. Followed the instructions. Now I'm getting the following error:

Dex merge    Error
Error in C:\Users\foakg\AppData\Local\Android\b4a-12-sdk\tools\..\extras\b4a_local\unpacked-okhttp-3.5.0-63703786950000\dex_v1\okhttp-3.5.0.zip:classes.dex:
Type okhttp3.Address is defined multiple times: C:\Users\foakg\AppData\Local\Android\b4a-12-sdk\tools\..\extras\b4a_local\unpacked-okhttp-3.5.0-63703786950000\dex_v1\okhttp-3.5.0.zip:classes.dex, C:\Users\foakg\AppData\Local\Android\b4a-12-sdk\tools\..\extras\b4a_local\unpacked-okhttp-4.9.0-63804276756000\dex_v1\okhttp-4.9.0.zip:classes.dex
Compilation failed

I'm assuming it might be caused by the existence of

OkHttp.jar
okhttp-3.5.0.jar
okhttp-4.9.0.jar

or

okio-1.11.0.jar
okio-2.8.0.jar

in the libraries folder. This didn't cause any problems with earlier version of B4A. Is there a way to recompile the libs by removing the duplicate ones?

If it's related, I tried to find the ini file for setting dexoptimization to false but it seems like I don't have the following folder:

%AppData%\Anywhere Software\Basic4android

Thanks

Which libraries are you using? One of them references the old okhttp library.

Hi Erel,

Here are the libraries used by the code:

When I first compiled, the dex optimizer worked, and when I remove any jar file (okhttp-3.5.0.jar or okhttp-4.9.0.jar) from the libraries folder, it complains, even though these are not being used per the library matrix above. Please see below:

Thanks

Just a guess but it could be...

Check DropboxHttpApi.xml and remove any reference if there is one.
Otherwise use the class, change the reference and compile the class again to a library.

 

[foakgul]

Right on @DonManfred ! Thanks a lot!

Turns out this was the culprit, solved by removing the library from the project altogether since I will not be using its functionality going forward in this release.

Cheers
