getActionBar() returns null after updating from AppCompatActivity to Activity

Question

I switched from supporting Gingerbread, since Play no longer supports it. I can now stop using support classes, and move to real ones. Except getActionBar is null

Android marshmallow
My Theme includes ActionBar (@Style.AppTheme)
extending Activity, not ActionBarActivity or AppCompatActivity
tried requestWindowFeature(Window.FEATURE_ACTION_BAR); before setContentView, and even before super.onCreate
calling getActionBar in onCreate after setContentView

styles.xml

<resources>

    <!--
        Base application theme, dependent on API level. This theme is replaced
        by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
    -->
    <style name="AppBaseTheme" parent="Theme.AppCompat.Light">
        <!--
            Theme customizations available in newer API levels can go in
            res/values-vXX/styles.xml, while customizations related to
            backward-compatibility can go here.
        -->
    </style>

    <!-- Application theme. -->
    <style name="AppTheme" parent="AppBaseTheme">
        <!-- All customizations that are NOT specific to a particular API-level can go here. -->

    -->
    <style name="AppBaseTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- API 14 theme customizations can go here. -->
    </style>

</resources>

styles.xml (v21)

    <style name="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>

You should keep using AppCompat. Even if you were API 21+ and could use the material themes, you'd still want to use it (there are changes even at API 23 that AppCompat takes care of for you). — ianhanniballake, Feb 21 '17 at 05:21
I checked all the solutions there, @Shailesh The whole point of switching to min sdk 14, is I no longer need to use AppCompat and supprotaction bar, i can use the real deal — f.khantsis, Feb 21 '17 at 05:24
@AnuragSingh AppTheme inherits from Theme.AppCompat.Light.DarkActionBar — f.khantsis, Feb 21 '17 at 05:25
Share your `style` xml code and java code which you are using to get `actionbar`. — Farmer, Feb 21 '17 at 05:25
OK, I put style code in the original question. The java code to get actionbar is irrelevent, I commented it out, and now the activity runs -- without an ActionBar. — f.khantsis, Feb 21 '17 at 05:34
Switching back to AppCompatActivity brought the actionbar back, but I want to use regular activities — f.khantsis, Feb 21 '17 at 05:49

Have you tried getSupportActionBar()? That worked for me when I had a similar issue.

You might also want to check one of the answers on this thread: getActionBar returns null

i did not try `getSupportActionBar` since I am not using the support `Activity` class. Also i tried all those solutions, hence the list of things I did in the post – f.khantsis Feb 21 '17 at 05:32

Reason being <item name="windowActionBar">false</item>. Remove this and try. No need to use Theme.AppCompat since you are not inheriting AppCompatActivity.

Check you manifest if u have added theme to you activity (if added then remove it).

Check if you have added correct theme to your Application

android:icon="@drawable/app_icon"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
    android:name=".activity.SplashScreen"
    android:label="@string/app_name" >
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />

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

i specifically said in the question that I am using `@Style.AppTheme` — f.khantsis, Feb 21 '17 at 19:10
