Android Error When Calling "requestWindowFeature( Window.FEATURE_PROGRESS );" in Activity

I'm attempting to display loading progress for a WebView in an Android Activity. When I attempt to display the window's progress bar with:

requestWindowFeature( Window.FEATURE_PROGRESS );

as per http://developer.android.com/guide/appendix/faq/commontasks.html#progressbar but at this point I get a debugging error.

When the error occurs I see a new tab "ActivityThread.performLaunchActivity" in Eclipse which has a message "Source not found." and a button "Edit Source Lookup Path...".

When I remove the offending line I don't get this error.

What could be causing this problem? Do I need to set a permission in the AndroidManifest.xml file or is there something else I'm missing?

It was changing to targetSdkVersion to 19 that made mine not work. And it was specifically the function requestWindowFeature function that broke it all. I removed it from my Manifest xml and just used minSdkVersion to 8 and it worked.

aliosmeen is right. You need extend Activity instead of ActionBarActivity. Both classes for some reason implement the requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS); method differently. I did it this way and it does not crash anymore. Although, you must call the requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS); method before you call the setContentView() method.

Use: 

public class MainActivity extends Activity

instead of:

public class MainActivity extends ActionBarActivity

Make sure you are calling requestWindowFeature( Window.FEATURE_PROGRESS ); before you call setContentView() in onCreate().

Have you tried making your requestWindowFeature() call before you call setContentView()?

This is necessary according to this post.

The docs for Window.requestFeature():

Enable extended screen features. This must be called before setContentView(). May be called as many times as desired as long as it is before setContentView().
