Android targetSdkVersion and NetworkOnMainThread Exception04/09/19 Permalink
I've just come across a runtime exception NetworkOnMainThreadException when upgrading the targetSdkVersion of an Android app. Basically what happens is Android will stop an app by refusing to load a class if it senses networking code is in the main app thread. I guess it's a way of preventing ANRs (App Not Responding).
To avoid having to redesign large portions of your app you can call this in onCreate:
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.
From here. This will prevent NetworkOnMainThreadException from being thrown. Only do this if you're sure your network connection is reliable.
