mainactivity.java

    package com.example.abrate.myapplication;  import android.support.v7.app.actionbaractivity; import android.os.bundle; import android.view.menu; import android.view.menuitem;   public class mainactivity extends actionbaractivity {      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);     }       @override     public boolean oncreateoptionsmenu(menu menu) {         // inflate menu; adds items action bar if present.         getmenuinflater().inflate(r.menu.menu_main, menu);         return true;     }      @override     public boolean onoptionsitemselected(menuitem item) {         // handle action bar item clicks here. action bar         // automatically handle clicks on home/up button, long         // specify parent activity in androidmanifest.xml.         int id = item.getitemid();          //noinspection simplifiableifstatement         if (id == r.id.action_settings) {             return true;         }          return super.onoptionsitemselected(item);     } }

androidmanifest.xml

    <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"     package="com.example.abrate.myapplication" >      <application         android:allowbackup="true"         android:icon="@mipmap/ic_launcher"         android:label="@string/app_name"         android:theme="@android:style/theme.holo.light" >         <activity             android:name=".mainactivity"             android:label="@string/app_name" >             <intent-filter>                 <action android:name="android.intent.action.main" />                  <category android:name="android.intent.category.launcher" />             </intent-filter>         </activity>     </application>  </manifest>

i don't know how fix issue, use theme.holo.light application , in android developers site (http://developer.android.com/guide/topics/ui/actionbar.html) written if api 11 or higher mainactivity.java should import "android.app.actionbar" , not "android.support.v7.app.actionbar", how fix issue? should go ahead using theme.appcompat or trying solve problem , use "android.app.actionbar" , theme.holo?

this android:theme="@android:style/theme.holo.light" in manifest needs appcompat

it written if api 11 or higher mainactivity.java should import "android.app.actionbar" , not "android.support.v7.app.actionbar"

this case (but not requirement there cases not possible) when had holo theme there material theme
