What Causes IllegalStateException. The IllegalStateException is thrown when the Java environment or application is not in an appropriate state for the requested operation. This can occur when dealing with threads or the Collections framework of the java.
In order to avoid java. lang. IllegalStateException in Java main Thread we must ensure that any method in our code cannot be called at an illegal or an inappropriate time. In the above example if we call start() method only once on thread t then we will not get any java.
Signals that a method has been invoked at an illegal or inappropriate time. In other words, the Java environment or Java application is not in an appropriate state for the requested operation.
I think this happens when you run the app from eclipse while you already have the previous version installed ? This won't happen if you uninstall the app before running it again from eclipse. Also, this won't cause any problems.

Try using older gradle dependencies version in you build.gradle file. It helped me.
Use:
compile 'com.android.support:appcompat-v7:23.1.0'
compile 'com.android.support:design:23.1.0'
Don't use:
compile 'com.android.support:appcompat-v7:23.2.0'
compile 'com.android.support:design:23.2.0'
