MoPub finally released their SDK for GDPR and I'm following their instructions and their code told me I did not need a consent, which makes sense since I'm in the US. I then switched to a VPN for Germany and it continued telling me the same. So how can I test this?
This is the code I'm using:
PersonalInfoManager mPersonalInfoManager = MoPub.getPersonalInformationManager();
boolean gdprApplies = mPersonalInfoManager.gdprApplies();
boolean shouldShowConsentDialog = mPersonalInfoManager.shouldShowConsentDialog();
Both gdprApplies and shouldShowConsentDialog were false when using the VPN in Germany and I even tried it after clearing data of the app.
I used VPN to get a European IP-address and the EU-consent dialog showed correctly. Maybe you need to clear cache or reinstall your app.
