I am in the BlogReader project and I am using both Eclipse and Genymotion emulators. All of a sudden when I loaded the app it shows me "Unfortunately, the BlogReader has stopped."
I am not sure what happened. Does anyone know why this happens?
Thanks a lot!

Courses Plus Student 14,658 PointsIt looks like the problem is that you're doing network activity on the main thread. You can see that on this line
03-06 00:06:12.122: E/AndroidRuntime(975): Caused by: android.os.NetworkOnMainThreadException
Network activity needs to be done in an AsyncTask. Ben talks about that in the lesson. If I remember correctly, the initial version of the blog reader that Ben writes encounters this same problem that you have. He does that on purpose to demonstrate that you can't do network activity on the main thread. If you're on the initial version of his program (before he fixes it either later in that lesson or in the next lesson), then that error is what's to be expected and there's no problem.
