"showStatusIcon on inactive InputConnection" in Android in camera application

Question

I am using camera app to take picture and put caption on it.I am facing error like "showStatusIcon on inactive InputConnection" and also it is saying like "Skipped 440 frames! The application may be doing too much work on its main thread."

I have put a thread while calling captureImage() method.How could I get rid of this problem.Here I am using web cam of my system and running the app in emulator.

My code is here:
