I want to hide title bar in Service without using Activity.Can I somehow do so?I thought it might work with requestWindowFeature and NO_TITLE_FEATURE but android studio says that it can't resolve this method.May be somebody can help me?
No, the title bar is part of the Activity. Therefore the Activity must control what window features it uses or doesn't use.

Sorry for the simple question but I cant figure out whats going on with this. The theme of my layout is set to NoTitleBar and the gui shows that slim bar where you pull notifications down from but when I run my app on my galaxy nexus its not there. It just shows white space where that bar is supposed to be. How do I make this bar with battery life and such show up. thanks
check your activity declared in mainfest file ..put your theme as no title bar in your activity in manifest file..if problem is not solve then put your code for better understanding
Does anyone know if there is a way to add custom buttons to the Android System Bar in Android 3.0+ (Honeycomb/ICS)?
I would like to add an application-provided button to that menu, but I have not been able to locate any API functionality that will allow it. I know that this area is sort of unofficially "off limits" to normal, non-system-level applicaitions, but I was wondering if anyone knew of a way to do this anyway?
Note: I am speaking specifically about the "System" bar that shows up along the bottom of the screen and not the "Action" bar which each app can customize at the TOP of the screen.
Let me know if you have any thoughts on this, thanks!!!

Sorry, this is not supported. You can add a Notification that will appear on the right side of the system bar, but not with the rest of the system buttons on the left.
If my fullscreen preference (off by default) is on, I want my Activity to hide the title bar as well as the notification bar. I can do that with requestWindowFeature(Window.FEATURE_NO_TITLE); + FLAG_FULLSCREEN etc. or perhaps setTheme(android.R.style.Theme_NoTitleBar_Fullscreen);
Either of these must happen before setContentView() or they will crash. The hard part is:
I target API levels 3 to 14, and I only want to hide the title bar if the Activity is not going to use an ActionBar. Otherwise, FEATURE_NO_TITLE will hide the ActionBar and lose some important controls. (I'll instead settle for "lights-out" mode.)
I can't see how to find out whether an ActionBar will be used until after setContentView(), when it's too late.
Things that don't work:
getActionBar() returns null at this early stage.
getWindow.hasFeature(Window.FEATURE_ACTION_BAR) is false.
Knowing (by reflection) that ActionBar exists as a class is insufficient, because, sticking with the default device theme, that might not always use ActionBar on some Ice Cream Sandwich devices, even though the platform has it. (?)
Alternatively: can I rely on ICS always having an ActionBar? Why?
Edit: ok, maybe ICS' title bar is still an ActionBar, just with no items and not even the overflow button? (In which case I still want to hide it.) Can anyone shed any light there?
Any ideas? :-)
I think what you want to use instead is ActionBarSherlock. It takes care of all the reflection and API level detection for you.
Would it be possible to do something like suggested here and here? Basically specify that on certain api levels, you hide the title bar (because you will have the action bar).
When i use Alert Dialog along with this
dialog.requestWindowFeature(Windows.FEATURE_NO_TITLE);
After using this ,the title bar comes for a few second and then vanishes.
How to handle this?
In your XML use this theme
android:theme="#android:style/Theme.NoTitleBar"
This will help you regarding your issue.
In my app i make the app fullscreen. Means android title bar and notification bar is hidden here.
But when i click on the spinner the hidden notification bar gets visible for fraction of seconds. It is not happening with all the spinners in my app. But where i use a array,generated by a loop execution in the spinner adapter, it is only happening in that case.
I have come to know that it is a known bug in android. I also use the following style in spinner to resolve it.

But still i cant solve this problem..
If anyone has any solution please let me know.
add this line before setContentView():
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
Then u use requestWindowFeature(Window.FEATURE_NO_TITLE); in activity and it must be before of the setContentView(....) method
