How to disable the title on the ActionBar in Main Launcher Activity

I checked this issue, couldn't find an answer.
there are 3 places I checked that show the label on 3 separated places in my android phone or app.
Under the logo of the app
In the app processes which show's the active apps, (from that window you can close the app process)
In the most annoying place, the "splash" action bar title (It happens before the MAIN activity UI start, when it loading the activity onCreate I believe), which most of us want to get rid of usually.
The 3 places are:
<application
android:name=".Application"
android:icon="#mipmap/icon"
android:label="#string/app_name" <!-- 1--- the first place-->
android:theme="#style/AppTheme">
<activity
android:name=".LoadingActivity"
android:label="#string/app_name" <!-- 2--- the second place-->
android:theme="#style/AppTheme.NoActionBar">
<intent-filter android:label="#string/app_name"> <!-- 3--- the third place-->
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
I checked on my phone (LG4 - android 5.1).
I saw that place 2 print on the action bar and the process but place 3 print on under the app icon in the phone.
BUT! when I checked in another phone (Hawaii P9 - android 6.0)
I saw place 2 printed under the app icon in the phone, unlike in LG4 which was place 3 who did this.
The main reason I actually checked it, is that I don't want the title to appear in the action bar, while I want it to appear under the app icon and in the processes.
Any help from an expert?

sorry for commenting in the answer section but that's cuz of the low reputation, will you add your onCreate method code in order to tell you how to use
.setTitle(" ");
in which you set the title blank to make the app name doesn't appear if that helps you

1) You could override the action bar , to use your custom action bar layout.
getSupportActionBar.setCustomView("your custom view");
2) If you just want to hide the title , you could set the title using
getSupportActionBar.setTitle("");
getSupportActionBar.setSubtitle("");

if (getSupportActionBar() != null) {
getSupportActionBar().setTitle("");
}

if (getSupportActionBar() != null) {
getSupportActionBar().setDisplayShowTitleEnabled(false);
}

From the answers you gave me, I figure a way to do what I need in a way.
I changed the main launcher activity to extend from AppCompatActivity instead of Activity, that way I could use your suggerstions you listed.
(Although I still wonder how to do it with the regular Activity)
The style themes was also enough for me, and it worked in a neater way!
<style name="MyActionBar" parent="#android:style/Widget.Holo.Light.ActionBar">
<item name="android:background">#color/colorPrimaryDark</item>
<item name="background">#color/colorPrimaryDark</item>
</style>
<style name="MyAppTheme.NoActionBar" parent="Theme.AppCompat.NoActionBar">
<item name="colorPrimary">#color/colorPrimaryDark</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="android:statusBarColor">#color/colorPrimaryDark</item>
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="android:windowBackground">#color/colorPrimaryDark</item>
<item name="android:actionBarItemBackground">#color/colorPrimaryDark</item>
<item name="android:actionBarStyle">#style/MyActionBar</item>
</style>
This xml style, fix the selected PrimaryColor in all of the wanted places and won't show the title in the main launch activity loading actionbar, while showing it under the icon and in the processes!

LeftNavBar creates black bar at the top of the activity

I'm trying to incorporate Google's LeftNavBarLibrary into my application. When I load the nav bar I end up with a black bar across the top of the activity. The bar appears to be taking up the space a traditional actionbar would occupy.
Does anyone know where the bar is coming from or how to remove it.
Thanks.
My application theme is slightly customized. Based on the AppCompat theme due to requirements of the MediaRouteActionProvider
styles.xml
<resources>
<style name="AppTheme" parent="#style/Theme.AppCompat">
<item name="android:actionBarStyle">#style/MyActionBar</item>
</style>
<style name="MyActionBar" parent="#style/Widget.AppCompat.ActionBar">
<item name="android:background">#drawable/ab_gradient</item>
</style>
</resources>
The activity pictured above has a custom theme defined in the manifest.
AndroidManifest.xml
<activity
android:name="my.app.namespace.CoreActivity"
android:theme="#android:style/Theme.Holo.NoActionBar.Fullscreen" >
</activity>
The applications minimum sdk version is 14. So it's not exclusively a Google TV app. I've only been able to test this bug on my Android 4.1 and 4.4 devices.

I deal with the action bar this way:
getActionBar().hide();
Try to put this in your main activity or the activity that is the parent and always present.
Don't bother about the theme in manifest, just set your theme with title bar and hide it through the code.
Hope this helps.

Take a look at: Hide the Status Bar on Android 4.0 and Lower
Notice that this is in the <application> tag. That might help you.
<application
...
android:theme="#android:style/Theme.Holo.NoActionBar.Fullscreen" >
...
</application>
or programmatically:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// If the Android version is lower than Jellybean, use this call to hide
// the status bar.
if (Build.VERSION.SDK_INT < 16) {
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
setContentView(R.layout.activity_main);
}

You can set android:windowActionBar style to false by setting custom theme.
Note: In this case getActionBar() will return null. If you remove the action bar using a theme, then the window will not allow the action bar at all.

Thanks for the answers guys. The real issue was actually that the LeftNavBar.java class was creating an artificial margin at the top of the screen. I'd have thought that a google published library would be better than that, but apparently not.

How to create fragment without action bar in android?

Hi all I have to create fragment with out action bar. Like this
In this picture I created Lienarlayout and placed that image in center. Below of that I want to create 4 fragments like projects,calender,filter and search. I searched a lot and tried by many codes but all the fragments has created with action bar. But i need to create fragments without action bar. How can I create that? Can anybody tell me? Thanks in advance.

ActionBars are actually components of your Activity objects and not your Fragments. (Take a look at the ActionBar documentation here). If your app is API level >= 11, your Activity objects will have ActionBars by default. These are set by the SDK-provided Holo theme. You can remove the ActionBar from the Activity to which your fragments are attached.
In order to do so, modify the Holo theme. Create a styles resource like so:
<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<style name="NoActionBar" parent="">
<item name="android:windowActionBar">false</item>
<item name="android:windowNoTitle">true</item>
</style>
</resources>
Then in your manifest you should associate the modified theme with the Activity that you want to be ActionBar-less:
<activity
android:name="com.yourproject.activity.NoActionBarActivity"
android:theme="#style/NoActionBar" >
</activity>

How to style Action Bar in styles.xml

I wanna remove the app icon from my action bar
I dont want the home icon there, I want to make more room for my other icons :) Now 4 of them are aligned to the right and the fifth one only shows up on the bottom when I press the settings key
I found this answer which looks promising
Open your styles.xml file and add below codes in your Actionbar style
<item name="android:displayOptions">showHome|homeAsUp|showTitle</item>
<item name="displayOptions">showHome|homeAsUp|showTitle</item>
<item name="android:icon">#android:color/transparent</item>
Problem is, I dont know what do they refer to as "your Actionbar style"
EDIT:
after having read some answers here is what I did to my manifest
<application
android:allowBackup="true"
android:debuggable="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/Theme.Sherlock.Light"
android:theme="#style/CustomActionBarTheme" >
and at the last line I get this error:
Attribute "theme" bound to namespace "http://schemas.android.com/apk/res/android" was already specified for element "application".
and this is my styles.xml:
<style name="CustomActionBarTheme">
<item name="displayOptions">showHome|homeAsUp|showTitle</item>
<item name="android:icon">#android:color/transparent</item>
</style>
Also I've tried
mActionBar.setDisplayHomeAsUpEnabled(false);
mActionBar.setDisplayShowHomeEnabled(false);
mActionBar.setDisplayShowTitleEnabled(false);
mActionBar.setDisplayUseLogoEnabled(false);
mActionBar.setHomeButtonEnabled(false);
It only makes the home icon invisible but it is still taking the space. Why have they provided 5 non-working methods here, what is the point? Why does it have to be so frustrating.

I worked around this issue in the following way:
- removed my settings icon
- then made my Home icon look like a settings icon
Now I have to find a way to make the Home icon open up the navigation drawer
And I also have to find a way to remove the huge blank space on the right side of the Home button so my icons are evenly spread.

Android - how to display the Action Bar using the default Theme.Light

I would like to use the default Android Theme.Light in one my activities.
However, when this particular theme is applied in my application Manifest file for the selected activity:
android:theme="#android:style/Theme.Light">
it hides the activity Action Bar.
What needs to be done in java or xml code to preserve the Action Bar, using this particular Light scheme ?
As an alternative, I have used the following default scheme:
android:theme="#android:style/Theme.DeviceDefault.Light">
That scheme does show the activity Action Bar correctly, however some of its objects are not displayed as preferred. In particular, my preference would be to display buttons and spinners as per Theme.Light, but preserve the other style formatting offered by the Theme.DeviceDefault.Light
I would greatly appreciate some tips on how to achieve the above scheme formatting preferences. (I am using SDK = 16).

Why not use "android:style/Theme.Holo.Light" ? is the same but has actionbar it was added in the newer apis

I think you should use Holo.Ligt theme. The old android Theme.Light is not even aware of action bar.

I have the same problem, I like Theme.light's controls, I resolved it like this:
1) define "Theme.Light.ActionBar" in project's styles :
<style name="Theme.Light.ActionBar" parent="#android:style/Theme.Light">
<item name="android:windowNoTitle">false</item>
<item name="android:windowActionBar">true</item>
</style>
2) in the manifest use it :
<activity
android:name="com.your.Activity"
android:theme="#style/Theme.Light.ActionBar" >
I hope that may help
