ClassCastException: java.lang.Integer cannot be cast to java.lang.String

[Jose Grillo]

Grettings, could you please help me, I´m trying to migrate ours current Android Sdk Version (3.16.0) to the newest one (3.19.0) but this has been quite dificult because didn't find updated documentation to migrate to this new version, could please told where could I find an example or documentation of how to migrate to this one?, Currently the lines told to have deprectaed funcs,

sdkFactory.createAdDisplayContainer()

adDisplayContainer?.adContainer = viewGroup

With createAdDisplayContainer and adContainer being deprecated, but didn´t find any clear instruction with what should they be replaced, annd also, if I try to run the project with the version, and those deprecated elements, android gives me this Log

Caused by: java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.String

        at android.app.SharedPreferencesImpl.getString(SharedPreferencesImpl.java:225)
        at com.google.ads.interactivemedia.v3.internal.aiq.k(IMASDK:18)

        at com.google.ads.interactivemedia.v3.internal.ail.doInBackground(IMASDK:13)

But this doesn´t give any clue because of the Proguard applied to the sdk?

Could please give any light here?

Best regards.

Hi Jose,

Thank you for reaching out to us. The changes made to the IMA SDK for Android from v3.16.0 to v3.19.0 are minor, therefore, we didn't publish any migration guide. However, you can take a look at our Android AdvancedExample sample as it will show you how to use the new API methods. In our AdvancedExample sample app, the AdDisplayContainer was created on this line.

Grettings, thanks Arnaud, I have made the changes, but still the weird issue appears

I have seen this issue sinnce the version 3.16.2, where you introduce SharedPreferences support, do you have any hint of what could this been happing, trying to investigate, this is telling me that the at com.google.ads.interactivemedia.v3.internal.aiq.k(IMASDK:18) is the import, on some class I couldn't see, with the import of ImaSdkFactory?

Does this tell you something?

Best regards.

Hi Jose,

 

Thank you for getting back to us on this.

 

I tried to use the advanced sample app v3.16, this sample app uses the SDK version 3.16.2 as default SDK. I've updated the SDK version to version 3.19.0 and this triggers the deprecation of createAdDisplayContainer method. Following the AdDisplayContainer implementation as shown in this line. I was able to build the app successfully and I wasn't able to reproduce the issue that you're facing.

 

That being said, could please try the above sample app and update the SDK to the latest version and see if you will encounter the same issue? Please let us know the result.

Grettings Sherwing, after several tries the issue is still happening, here is my implementation for sdk initialization, do you something is missing or something that could explain that weird exception with the shared preferences.

I keep that this happen since I try to aply the version .16.2 up

sdkSettings = sdkFactory.createImaSdkSettings()
adsRenderingSettings = sdkFactory.createAdsRenderingSettings()
adDisplayContainer = ImaSdkFactory.createAdDisplayContainer(viewGroup, this)
adsRenderingSettings?.enablePreloading = true
sdkSettings?.isDebugMode = BuildConfig.DEBUG
emVideoView?.blockPlayback = true
adsLoader = sdkFactory.createAdsLoader(context, sdkSettings, adDisplayContainer)
adsLoader?.addAdsLoadedListener(this)
adsLoader?.addAdErrorListener(this)
...

The bug is 

Caused by: java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.String

Hi Jose,

The issue you reported is not with the IMA SDK, I've run our AdvancedExample (v3.16.2) sample several times and was not able to reproduce the error message you shared. Your implementation is at many points different from ours, we create the AdDisplayContainer passing the AdUIContainer and the video ad player to the createAdDisplayContainer method, in your implementation, you're passing a viewGroup and the keyword this. When it comes to register to the events listeners, we're passing callbacks to the addAdsLoadedListener and addAdsErrorListener, in your use case you're passing the keyword this. The best thing would to debug your implementation against our Android AdvancedExample to fix the issue you're facing.
