RuntimeException in Handler.<init>() #679

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
This error happens when update UI in a worker thread(non-main thread). Can we 
add a method , for example handleMessage(String msg) , to handle such issues?

The stack trace of this error:

Currently I cannot reproduce it, does anybody know the key?

What steps will reproduce the problem?

What is the expected output? What do you see instead?
