My manifest does not reference any themes... it should not have to AFAIK

Sure it does. Nothing is going to magically apply Theme.Styled to an activity. You need to declare your activities -- or your whole application -- is using Theme.Styled, e.g., :

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/Theme.Styled">

To simply add ActionBar Compat your activity or application should use  style Theme AppCompat theme in AndroidManifest xml like this       lt activity                     android theme   style Theme AppCompat    gt    This will add actionbar in activty or all activities if you added this theme to application     But usually you need to customize you actionbar  To do this you need to create two styles with Theme AppCompat parent  for example    style Theme AppCompat Light   First one will be for api 11    versions of android with build in android actionbar   second one for api 7-10  no build in actionbar    Let s look at first style  It will be located in res values-v11 styles xml   It will look like this    lt style name  Theme Styled  parent   style Theme AppCompat Light  gt       lt  -- Setting values in the android namespace affects API levels 11  -- gt       lt item name  android actionBarStyle  gt  style Widget Styled ActionBar lt  item gt   lt  style gt    lt style name  Widget Styled ActionBar  parent   style Widget AppCompat Light ActionBar  gt       lt  -- Setting values in the android namespace affects API levels 11  -- gt       lt item name  android background  gt  drawable ab custom solid styled lt  item gt       lt item name  android backgroundStacked         gt  drawable ab custom stacked solid styled lt  item gt       lt item name  android backgroundSplit         gt  drawable ab custom bottom solid styled lt  item gt   lt  style gt    And you need to have same style for api 7-10  It will be located in res values styles xml  BUT because that api levels don t yet know about original android actionbar style items  we should use one  provided by support library  ActionBar Compat items are defined just like original android  but without  android   part in the front    lt style name  Theme Styled  parent   style Theme AppCompat Light  gt       lt  -- Setting values in the default namespace affects API levels 7-11 -- gt       lt item name  actionBarStyle  gt  style Widget Styled ActionBar lt  item gt   lt  style gt    lt style name  Widget Styled ActionBar  parent   style Widget AppCompat Light ActionBar  gt       lt  -- Setting values in the default namespace affects API levels 7-11 -- gt       lt item name  background  gt  drawable ab custom solid styled lt  item gt       lt item name  backgroundStacked  gt  drawable ab custom stacked solid styled lt  item gt       lt item name  backgroundSplit  gt  drawable ab custom bottom solid styled lt  item gt   lt  style gt    Please mark that  even if api levels higher than 10 already have actionbar you should still use AppCompat styles  If you don t  you will have this error on launch of Acitvity on devices with android 3 0 and higher      java lang IllegalStateException  You need to use a Theme AppCompat   theme  or descendant  with this activity    Here is link this original article http   android-developers blogspot com 2013 08 actionbarcompat-and-io-2013-app-source html written by Chris Banes   P S  Sorry for my English

I encountered this error when I was trying to create a DialogBox when some action is taken inside the CustomAdapter class   This was not an Activity but an Adapter class  After 36 hrs of efforts and looking up for solutions  I came up with this   Send the Activity as a parameter while calling the CustomAdapter   CustomAdapter ca   new CustomAdapter MyActivity this getApplicationContext   records     Define the variables in the custom Adapter   Activity parentActivity  Context context    Call the constructor like this   public CustomAdapter Activity parentActivity Context context List lt Record gt  records       this parentActivity parentActivity      this context context      this records records      And finally when creating the dialog box inside the adapter class  do it like this   AlertDialog ad   new AlertDialog Builder parentActivity  setTitle  Your title     and so on     I hope this helps you

I had such crash on Samsung devices even though the activity did use Theme AppCompat  The root cause was related to weird optimizations on Samsung side   - if one activity of your app has theme not inherited from Theme AppCompat - and it has also  android launchMode  singleTask   - then all the activities that are launched from it will share the same Theme   My solution was just removing android launchMode  singleTask

Just do it Build -  Clean Project  I think this will solve your problem

Check and make sure that you do not have another values folder that references theme styled and does not use AppCompat theme  ie values-v11 folder

Your Activity is extending ActionBarActivity which requires the AppCompat theme to be applied  Change from ActionBarActivity to Activity or FragmentActivity  it will solve the problem

If you are extending ActionBarActivity in your MainActivity  you will have to change the parent theme in values-v11 also  So the style xml in values-v11 will be -     lt  -- res values-v11 themes xml -- gt    lt  xml version  1 0  encoding  utf-8   gt    lt resources gt       lt style name  QueryTheme  parent   style Theme AppCompat  gt       lt  -- Any customizations for your app running on devices with Theme Holo here -- gt       lt  style gt    lt  resources gt    EDIT  I would recommend you stop using ActionBar and start using the AppBar layout included in the Android Design Support Library
