          android:label="@string/app_name"
          android:exported="true">

              <action android:name="android.intent.action.MAIN" />
              <category android:name="android.intent.category.LAUNCHER" />

public class SplashActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Intent intent = new Intent(this, MainActivity.class);
        startActivity(intent);
        finish();
    }
}

MainActivity에 아래 부분 추가

import android.os.Bundle;


  @Override
    protected void onCreate(Bundle savedInstanceState) {
        SplashScreen.show(this);

    }
