Apparently there is a task running which is using the context here with OpenCBLoader

(!OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_3, this, mLoaderCallback))

The problem related with context i.e the context is not valid anymore .Try passing getApplicationContext() instead of this

(!OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_3, getApplicationContext(), mLoaderCallback))

Consider a case when AMK(android memory killer) kill your service due to memory shortage because service get to destroyed first before foreground activity and now your service is dead, plus the this context is not valid anymore hence Exception
