Description

I am using OpenCV library version 2.4.3 on my android project. On the emulator everything works when I installed manually opencv manager, but I have a problem on the device (Samsung Galaxy S Advance with Android 2.3.6). When I call initAsync function I get NullPointerException, but I suppose I should get a message that OpenCV Manager packages was not found and can install it from google play.

I see that in LogCat:

Not OpenCV issue.
It looks like context passed for OpenCV Manager initialization is not valid or become invalid during initialization of has no privileges to create AlertDialog.
