Question

I add Version detection in the entrance of activity. And add the following code in onCreate method.

new Thread(){
         public void run(){
         try{
         checkToUpdate();
         }
            catch(Exception e) {
            }
         }
            }.run();

Now it has a new thread. But why it has the error: android.os.NetworkOnMainThreadException in android 4.0?

thanks in advance!

Answer 1

it should be start() instead of run()

new Thread(){
         public void run()
         {
            try{
            checkToUpdate();
         }
            catch(Exception e) {
            }
         }
            }.start();

And may be you have not added internet permission in manifest file

<manifest xlmns:android...>
 ...
 <uses-permission android:name="android.permission.INTERNET"></uses-permission>
</manifest>
