Eclipse stuck in running program

This image is after completing the eclipse task.

There are no errors in my Android program, and everything was in order before this problem. This happened when I added the code to my program. It gets stuck after pressing the start button. This also happens when I run my hand-held phone to debug a program. Other programs work fine, only one stuck.

the meaning of my stuck is an eclipse keep show progress bar launching myprogram (100%), but there was no emulator in it.

    final android.net.NetworkInfo mobile =
    connMgr.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
