2.create splash_screen.xml file in drawable and add this code

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


    <item android:drawable="@color/dark_blue" />
    <item>
        <bitmap
            android:gravity="center"
            android:src="@drawable/logo" />
    </item>

</layer-list>

3.Update your theme.xml

<resources xmlns:tools="http://schemas.android.com/tools">
    <!-- Base application theme. -->
    <style name="Theme.Music" parent="Theme.MaterialComponents.DayNight.DarkActionBar">
        <!-- Primary brand color. -->
        <item name="colorPrimary">@color/purple_500</item>
        <item name="colorPrimaryVariant">@color/purple_700</item>
        <item name="colorOnPrimary">@color/white</item>
        <!-- Secondary brand color. -->
        <item name="colorSecondary">@color/teal_200</item>
        <item name="colorSecondaryVariant">@color/teal_700</item>
        <item name="colorOnSecondary">@color/black</item>
        <!-- Status bar color. -->
        <item name="android:statusBarColor" tools:targetApi="l">@color/dark_blue</item>
        <!-- navigation bar color. -->
        <item name="android:navigationBarColor" tools:targetApi="lollipop">@color/light_black</item>
        <item name="android:colorEdgeEffect">@android:color/transparent</item>
        <item name="colorControlHighlight">@color/ripple_color</item>
        <item name="android:background">?attr/selectableItemBackground</item>
        <item name="android:windowBackground">@color/dark_blue</item>
        <item name="android:windowContentTransitions">true</item>

    </style>

    <style name="SplashScreen" parent="Theme.MaterialComponents.DayNight.NoActionBar">
        <item name="android:windowBackground">@drawable/splash_screen</item>
        <item name="android:statusBarColor" tools:targetApi="l">@color/dark_blue</item>
        <item name="android:navigationBarColor" tools:targetApi="lollipop">@color/light_black</item>
    </style>

</resources>

4.update your AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="com.example.music">
    
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
        tools:ignore="ScopedStorage" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/Theme.Music">
        <activity android:name=".MainActivity"></activity>
        <activity android:name=".SplashScreen"
            android:theme="@style/SplashScreen">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

</manifest>

5.Create a SplashScreen.java File in Your Project and add this code 

public class SplashScreen extends AppCompatActivity {


    public static final int REQUEST_CODE_FOR_PERMISSION = 1;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        checkStoragePermission();
    }

    private void checkStoragePermission() {
        if (ContextCompat.checkSelfPermission(this,
                Manifest.permission.WRITE_EXTERNAL_STORAGE)!= PackageManager.PERMISSION_GRANTED){
            //asking permission
            ActivityCompat.requestPermissions(this,
                    new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, REQUEST_CODE_FOR_PERMISSION);
        }else {
            nextActivity();
        }
    }


    @Override
    public void onRequestPermissionsResult(int requestCode,
                                           @NonNull  String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        if (requestCode == REQUEST_CODE_FOR_PERMISSION){
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED){
                nextActivity();
            }else {
                //asking permission
                ActivityCompat.requestPermissions(this,
                        new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, REQUEST_CODE_FOR_PERMISSION);
            }
        }
    }

    private void nextActivity(){
        Intent intent = new Intent(SplashScreen.this,MainActivity.class);
        startActivity(intent);
        finish();
    }
}
