Which plugin did you use?

firstseed · June 14, 2016, 7:48am

AdMob plugin

iPruch · August 11, 2016, 8:50am

Any update on this?

We had reports of these issue on other thread. This looks like an issue when the project is using different versions of SDKBOX plugin. Should be able to fix it with replacing everything with latest SDKBOX, are you also experiencing this issue?

iPruch · August 11, 2016, 6:56pm

Yes, I reported it here: SDKBox AdMob Crash

I don’t know what do you mean by “replacing everything with latest SDKBOX”. I think I have the last version already installed ( v1.0.0.15 )

yinjimmy · August 12, 2016, 1:52am

I can’t reproduce the issue.

Would you please send me all the sdkbox data.

proj.android folder if you use pre-build framework engine.
or
cocos2d/cocos/platform/android/java/libs and proj.android folders if you use source code engine.

I want to check the data.

Thanks,

iPruch · August 12, 2016, 1:53pm

Sure, I’ll send you a private message. Thanks!

iPruch · August 23, 2016, 9:48pm

Any news on this?

yinjimmy · August 25, 2016, 2:41am

En, I checked the data, the plugin is v2.2.5.3 .

And I’m digging the issue.

yinjimmy · August 25, 2016, 7:58am

Hello, can you help to test this issue, I think I have fixed it. but can you help me to double check it ?

sdkbox.jar.zip (71.6 KB)

Please backup your skdbox.jar and using mine.

Thank you !
Jimmy

iPruch · August 25, 2016, 9:36am

Sure, I’ll test it right now

iPruch · August 25, 2016, 1:30pm

I replaced my sdkbox.jar file with the new file you uploaded, cleaned the project and recompiled it. Seems to be more stable (or maybe it’s just my imagination), but still getting this crash at some point:

I don’t know what’s wrong with my project
Maybe it’s caused because I reload my scene each time the player presses the play again button? I’m setting SDKBOX plugins’ listeners this way:

Scene* GameScene::createScene()
{
    // 'scene' is an autorelease object
    auto scene = Scene::create();
    
    // 'layer' is an autorelease object
    auto layer = GameScene::create();
    
    // Set SDKBOX Ads listener
    CCLOG("PLUGIN SDKBOX ADS/PLAY: SET LISTENER");
    
    #ifdef SDKBOX_ENABLED
    sdkbox::PluginSdkboxAds::setListener(layer);
    sdkbox::PluginSdkboxPlay::setListener(layer);
    #endif
    
    // add layer as a child to scene
    scene->addChild(layer);
    
    // return the scene
    return scene;
}

So everytime the scene is reloaded, the listener is set again pointing to the new scene object. I’m suspecting of this because I see on the crash dump this line: sdkbox::PluginSdkboxAdsNativeBridgeAdObserver::operator()

What do you think?

Edit: I forgot to say that I created a test button on my game that will shot an ad every time I touch it, and this way I can play lots of ads without crashes. Therefore, crashes are related to the scene reloading in some way (maybe something about the PluginSdkboxAds::setListener call as I said before).

UPDATE: I can confirm that my crashes are related to the PluginSdkboxAds::setListener call. I just commented it and no crashes at all! The bad side about this workaround is that now I won’t receive any PluginSdkboxAds callback, but right now I’m not making any use of them aside from a CCLOG to know what’s happening.

yinjimmy · August 25, 2016, 3:07pm

Yes, I test the issue using sdkbox-sample-sdkboxads/cpp, click play placement-1 lots of times, without crash.

How about just setListener once ?

Can you provide a test sample using cocos framework ?

Thank you !
Jimmy

iPruch · August 25, 2016, 3:45pm

The problem is that I need to call setListener every time the scene reloads, or the PluginSdkboxAds will be pointing to a released scene object.

I’ll try reproducing the crash in a sample project next week. I’m in a hurry here to finish the Android version of my game, but I’ll do it asap I finish the work

Thank you for your replies!

yinjimmy · August 25, 2016, 3:47pm

Can you try this libs.zip (470.2 KB) , replace the proj.android/jni/pluginsdkboxads/libs folder.

iPruch · August 25, 2016, 4:09pm

I have no pluginsdkboxads folder inside proj.android/jni, so there’s nothing to replace:

I’m using cocos source code engine

yinjimmy · August 25, 2016, 4:25pm

cocos/platform/android/jni/

iPruch · August 25, 2016, 4:38pm

Also looked into that folder, but there is no pluginsdkboxads in there:

nite · August 25, 2016, 6:06pm

If you don’t have pluginsdkboxads in the jni folder, that means the integration is not complete. We try to automate all the integration process, but sometimes it happens. Please follow the manual integration process to double check if all the required files are in place.
