Air 27 Beta: Android NullPointerException: at com.adobe.air.AIRWindowSurfaceView.surfaceChanged

[rewb0rn]

Hi Adobe Air team!

we are seeing a new NullpointerException when publishing to live from Air SDK 27 Beta. I hope the following information helps to identify and fix the error (sorry for the German screen, I can't easily switch the language). This new exception is one of the most frequent exceptions we are currently seeing in the dashboard:

Exemplary stack trace:

Hello,

can anyone help? We are seeing this exception on all our production apps with Air 27 and it is still a problem with Air 27.0.0.124. I see that 2 other people upvoted my question, can you share your experiences with the exception?

Is the Adobe Air team looking into this? Anything we can do to help fixing the issue?

Thanks in advance

Hi – yep we're seeing this error too, however we're using Air SDK 23.0, not 27. The error is happening on the exact same line number of AirWindowSurfaceView.java.

Did you have any luck solving the issue? We have no idea what's causing it at the moment.

Here's a typical stack trace:

no idea how to fix this sorry. I assume this is an Air error and it should be fixed in the SDK.

There's a forum thread on Starling's github page discussing this. Currently quite active (Dec 2017):
