In-App Purchases

SDL Development
1

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” <d.ruler501 at gmail.com> 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:
https://dl.dropboxusercontent.com/u/38460079/InAppPurchaseCode.zip

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.

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.

The code is not available anymore, can you share it again? would it work with the modern version of the google libs?
