We initialize OpenCV4Android using
OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_3, activityContext, baseLoaderCallback);
The situation I am facing is that in my launcher Activity, I have two buttons, and clicking on them results in a start of a different Activity. Let's call those activities A and B.
My JavaCameraView is in one of those two activities, say A. So I am executing the above statement in A.
But what if the user never enters the Activity A, what if they directly enter the Activity B? I need the OpenCV4Android to be initialized in Activity B as well.
So I need to do something like:
if (OpenCV4Android IS NOT INITIALIZED) {
OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_3, activityContext, baseLoaderCallback);
}
How do I perform that check in `if`?
