This is the last scenario for using the spalsh screen in a different way without creating any layout for it to display when the app starts. Here we are going to set a permission dialog that will ask for some permissions in the app and it will be asked at the time of app loading means in the spalsh screen.
There are 3 steps to perform in order to create this kind of splash screen without any layout for the screen.
1.) You have to define one style in the values folder of your app. Create the following style in your
app.
2.) After doing this, you have to apply this style to your screen in AndroidManifest.xml. Add the following code in the manifest file inside the application tag.
3.) Add the following code in your SplashActivity.java.

1.) You have to define one style in the values folder of your app. Create the following style in your
app.
<style name="splashScreenTheme" parent="Theme.AppCompat.NoActionBar">
<item name="android:windowBackground">@drawable/splash_screen</item>
<item name="windowActionModeOverlay">true</item>
</style>2.) After doing this, you have to apply this style to your screen in AndroidManifest.xml. Add the following code in the manifest file inside the application tag.
Now, we will modify the SplashActivity.java to add the permission dialog to show at startup of the app and then the app will redirect the user to MainActivity.java after all the permissions are given by the user.<activity android:name="com.android.splashscreendemo.activity.SplashActivity" android:label="@string/app_name" android:launchMode="singleTask" android:screenOrientation="portrait" android:theme="@style/splashScreenTheme"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity>
3.) Add the following code in your SplashActivity.java.
