AppCompat Theme Error when using NoActionBar

I'm using a toolbar for my entire application. So I have set up my application Theme to Theme.AppCompat.Light.NoActionBar But I need to show a alert dialog in a part of my app. When I try to show alert dialog I'm getting Runtime error about Theme.Appcompat

enter image description here

My manifest.xml file

<application
    android:allowBackup="true"
    android:icon="@drawable/app_icon2"
    android:label="@string/app_name"
    android:theme="@style/Theme.AppCompat.Light.NoActionBar"
    >
    <activity
        android:name="com.project.project.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>
    <activity
        android:name="com.project.project.StActivity"
        android:configChanges="orientation|screenSize|keyboardHidden"
        android:label="@string/app_name">
        <intent-filter >
            <action android:name="android.intent.action.DEFAULT" />

            <category android:name="android.intent.category.LAUNCHER" />

        </intent-filter>
    </activity>



</application>

It's hard to tell without seeing the code where you actually create the Dialog, but my guess is that you're either:

  1. Not using the Activity as the Context when you create the Dialog. The Activity context holds the theme; if you tried using the Application it wouldn't get the right theme.
  2. Setting your Dialog theme to something that doesn't inherit from Theme.AppCompat (using the constructor, setStyle() or ContextThemeWrapper).

Either way, the Dialog doesn't get the required attributes provided by Theme.AppCompat.
