javaandroidandroid-fullscreen

Android, no AppCompat, full screen - the most correct style?

Android app, strictly level 21 onwards only. Not using AppCompat.

Full-screen app with absolutely no bars.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.client.client">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"

        android:theme="@style/AppTheme">

        <activity android:name=".Main"
            android:screenOrientation="portrait"
            android:theme="@android:style/Theme.Holo.Light.NoActionBar.Fullscreen">

            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
</manifest>

Am confused between:

android:theme="@android:style/Theme.NoTitleBar.Fullscreen"

versus...

android:theme="@android:style/Theme.DeviceDefault.NoActionBar.Fullscreen"

What is the best and most modern choice?

I don't understand the complete history of the difference between those and similar values in Android :/

Again, not using AppCompat, if that matters.

Here's a screenshot of how I want the app to look on all devices:

  • what is the best and most modern choice?

    With a minSdkVersion of 21+, you can use themes based off of Theme.Material, such as Theme.Material.Light.NoActionBar.Fullscreen.
