The SDL forums have moved to discourse.libsdl.org.
This is just a read-only archive of the previous forums, to keep old links working.

I'm looking for a cross-platform(iOS and Android) way to process and verify in-app purchases. Is this possible? If not what is the best way to do it for each of those two platforms, note I'm using C++ not C.

Not really related to SDL is it? On Sep 20, 2014 10:32 PM, "ruler501" wrote:

Not especially so just in that this is an SDL app and both are attempts at cross-platform code.

I doubt that there is a cross-platform way. You would need to code for both iOS and Android separately. The way I did it was to create an in-app purchase interface class & then made platform specific derived classes. The iOS specific class tapped into the Objective C API and the Android specific class used JNI to call google's API.


It was a tedious and sometimes non-obvious process, but it worked.

Could you maybe share the code? Maybe a third party lib could unify that in the sdl way. Am 22.09.2014 07:23 schrieb "Pallav Nawani":

I'd be willing to put some time in to try and make this have a cross platform API if it is possible, I'd need to see the code before deciding that though

Okay, I will share the code. However, the code might be tied to our game engine, and it might need to modified quite a bit.

Thank you, and I'll see what we can do to tidy it up for you and make it more of a library

As Promised, here is the In-App Purchase Code:

I have tried a bit to make it clear & self contained, however I am sure that some changes will be needed, esp. in the Android code. I will be out of station from Today till 29th September, so I will not be able to answer any questions during that time.

Thanks for the code, it is greatly appreciated.

It does seem to be missing a few headers though(XAppBase.h, misc/XF_Log.h, os/xf_os_android_jni.h) otherwise it seems to be working great, and though I'm not sure if we could make a library out of it, because of the android complications I think I could write some scripts to make it seem almost like a plug and play library.

I managed to edit it so it would compile, but I'm not certain my edits were correct, what is mClassPath = pApp->mJavaClassPath; supposed to do? I just assumed it returned the path of the main package in my code.

Also does XFOsAndroidManageLocalRef aLocalRef(aEnv); do anything? It seems the value was never used so I commented out those lines.

I also had to remove most of the logging since that header was missing.

Thanks a lot for the code

Those other headers are not required, you can simply remove them.
ClassPath is the path for the main activity, like:


mClassPath  = "com/ironcode/droid/PahelikaSecretLegends/PahelikaSecretLegends";


basically used to call the methods defined in the game's activity via JNI.


XFOsAndroidManageLocalRef aLocalRef(aEnv); 

is used to ensure that JNI doesn't garbage collect local variables we create via JNI before we are done using them. I am not quite sure whether this works at all though, I just had it as a safety measure.
