Exceptions on reconnect #543

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Connect to SensorSimulator, read some data, disconnect
2. Connect again.

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

There are few problems with reconnect. Sometimes application hangs, especially 
when no "Disconnect()" is logged in the LogCat console. Even if reconnecting 
after this log message was received the client crashes with couple of the 
exceptions.

First:

Second:

java.util.ConcurrentModificationException

Not telling about the threading issues in the latest Android SDK. 
SensorSimulator demo code works only after disabling StrictMode:

StrictMode.setThreadPolicy(new 
StrictMode.ThreadPolicy.Builder().permitAll().build());
