Stuck on splash screen on first launch but if we don't kill app and launch app again the app works fine. (react-native) Android

I have upgraded code to react-native 0.59.9 from 0.53.3. I think I may have missed some essential steps and getting launch issues. Please check and help me to make app work fine.

React Native Navigation version: 4.0.6

React Native version: 0.59.9

Platform(s) (iOS, Android, or both?): Android.

Device info: Device and Simulator Both (All Android versions).

MainActivity.java

public class MainActivity extends NavigationActivity {static Backbonebits b;public void addDefaultSplashLayout() {LinearLayout splash = new LinearLayout(this);Drawable splash_screen_bitmap = ContextCompat.getDrawable(getApplicationContext(),R.drawable.splashscreen);splash.setBackground(splash_screen_bitmap);    setContentView(splash);}@overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);MobileAds.initialize(this, new OnInitializationCompleteListener() {@overridepublic void onInitializationComplete(InitializationStatus initializationStatus) {}});b = new Backbonebits(this);}}

MainApplication.java

public class MainApplication extends NavigationApplication {private static CallbackManager mCallbackManager = CallbackManager.Factory.create();protected static CallbackManager getCallbackManager() {    return mCallbackManager;} @Override protected ReactGateway createReactGateway() {     ReactNativeHost host = new NavigationReactNativeHost(this, isDebug(), createAdditionalReactPackages()) {         @Override         protected String getJSMainModuleName() {             return "index";         }     };     return new ReactGateway(this, isDebug(), host); } @Override public boolean isDebug() {     return BuildConfig.DEBUG; }protected List<ReactPackage> getPackages() {  return Arrays.<ReactPackage>asList(        new MainReactPackage(),        new FBSDKPackage(mCallbackManager),  );} @Override public List<ReactPackage> createAdditionalReactPackages() {     return getPackages(); }}
