title: Changing Theme.Holo on Android Manifest.xml file doesn't run on Android
body: <p>I am very new to android app development, and have recently hit a wall on the <a href="https://developer.android.com/training/basics/actionbar/styling.html" rel="nofollow"><em>Styling the Action Bar page</em></a>. </p>
  
  <p>Every time I change the theme to <code>android:theme="@android:style/Theme.Holo.Light"</code> just doesn't allow the program to run on the android, with a message saying "Unfortunately, Program has stopped." every time I try to run it. Weird thing is that it saves perfectly fine on Eclipse with no errors.</p>
  
  <p>Here's my manifest file:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.example.myfirstappv2"
      android:versionCode="1"
      android:versionName="1.0" &gt;
  
      &lt;uses-sdk
          android:minSdkVersion="11"
          android:targetSdkVersion="19" /&gt;
  
      &lt;application
  
          android:allowBackup="true"
          android:icon="@drawable/ic_launcher"
          android:label="@string/app_name"
          android:theme="@android:style/Theme.Holo"&gt; 
  
          &lt;activity
              android:name="com.example.myfirstappv2.MainActivity"
              android:label="@string/app_name" &gt;
              &lt;intent-filter&gt;
                  &lt;action android:name="android.intent.action.MAIN" /&gt;
  
                  &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
              &lt;/intent-filter&gt;
          &lt;/activity&gt;
          &lt;activity
              android:name="com.example.myfirstappv2.DisplayMessageActivity"
              android:label="@string/title_activity_display_message"
              android:parentActivityName="com.example.myfirstappv2.MainActivity" &gt;
              &lt;meta-data
                  android:name="android.support.PARENT_ACTIVITY"
                  android:value="com.example.myfirstappv2.MainActivity" /&gt;
          &lt;/activity&gt;
      &lt;/application&gt;
  
  &lt;/manifest&gt;
