Warning - sending message to a Handler on a dead thread

Question

the application is running fine but all of a sudden I getting these warnings. Even though my app is running fine now I think it might cause error in the future. Currently the code is kind of huge so I cannot upload it here. But I will tell you the features that I am using in my app. 1. Google Maps 2. GCM 3. Server related stuff - fetching json data etc etc

Can some one please tell me why it may be causing this error? below is the logcat warnings
