Solution is change the Java inheritance from ActionBarActivity to Activity and leave the dialog theme in the manifest as it is, a non Theme.AppCompat value

In your case issue is with your manifest file you haven't specified android:theme="@style/AppTheme.NoActionBar" inside activities tag

Go your manifest file and replace splash activity with this:

<activity
            android:name=".activities.SplashActivity"
            android:theme="@style/AppTheme.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

Inside your splash activity class do this:

public class SplashActivity extends AppCompatActivity
