Android – oncreate() was not called

I've just encountered a very strange problem, and I've spent hours trying to solve it. When I try to run my Android application (on my phone and simulator), I get nothing. The activity tag (Android: label = "@ string / list_name") in the androidmanifest file is set correctly, but I just have a flashing screen

I inserted a breakpoint and 30 log. D() after super() of oncreate() method, but I never reached the breakpoint and never printed log. D(). In addition, I didn't have any exceptions in logcat

The application has worked before, and I don't know how it never reached the breakpoint

PS: This is my main activity

PS2: I have cleaned up the project, rebuilt it and restarted it. The problem does not disappear:（

PS3: my oncreate() is very long, but this is where it starts:

@Override
public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.episode);
        Log.d("Very Strange", "This is never printed");
        Log.d("Very Strange", "This is never printed");
        // no breakpoints is every reached

My manifest file can be found here: http://pastebin.com/UcKbYeGC

resolvent:

Try this:

 public void onCreate(Bundle savedInstanceState)
 {
    Log.d("Very Strange", "Printed #1?");
    super.onCreate(savedInstanceState);
    Log.d("Very Strange", "Printed #2?");
    setContentView(R.layout.episode);
    Log.d("Very Strange", "This is never printed");
    Log.d("Very Strange", "This is never printed");

Just an off topic tip: use the version control system to ensure that you can roll back or compare work with the current version
