Android Build an Interactive Story App (Retired) User Input Hiding the ActionBar with an App Theme

App keeps crashing when using android:Theme.Holo.Light.NoActionBar

I change my AppThem from parent="Theme.AppCompat.Light.DarkActionBar" to "android:Theme.Holo.Light.NoActionBar.Fullscreen" and the app keeps crashing at launch

What happens is that your "MainActivity.java" file class must extend the "Activity" class instead of the "ActionBarActivity" its inheriting from. Once you change it (extends Activity) and make sure you include

 "import android.app.Activity;" 

at the beginning, you should be able to follow along with the video.

Change it to:

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
</style>

If you don't want to have an actionbar on the screen. Hope it works.

What I did was, remove the line import android.support.v7.app.AppCompatActivity;, because I guessed it's a class which lets the activity have only AppCompat themes, and not other themes. Therefore, your code would look like this:

MainActivity.java
package com.yournamehere.interactivestory;

import android.app.Activity;
import android.os.Bundle;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Your other code goes after this
    }
}

I hope this helps!

I was having a similar issue when I was trying to get the action bar to display. I removed

<android.support.design.widget.AppBarLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"/>

</android.support.design.widget.AppBarLayout>

from my activity_main.xml file and then I had a functioning actionbar. So, maybe try this?
