Crash with Null Pointer Exception reported recently


#1

Recently, we received a lot of crash reports on following:

java.lang.NullPointerException
at android.webkit.DeviceMotionService$2.run(DeviceMotionService.java:102)
at android.os.Handler.handleCallback(Handler.java:587)
at android.os.Handler.dispatchMessage(Handler.java:92)
at android.os.Looper.loop(Looper.java:132)
at android.webkit.WebViewCore$WebCoreThread.run(WebViewCore.java:715)
at java.lang.Thread.run(Thread.java:1020)

We have identified some Ads with javascript that accessing device motion service with cause the app crash for devices running Android OS 4.4 below.

May I know how to identify this type of Ads in Mopub developer console to disable serving these Ads for devices with Android OS 4.4 below?
Also, is it possible to update Mopub SDK to handle this exception/crash?

Thanks.
