4. issue description

The Lottie splash screen is working well on the development stage as I expected, thanks for your efforts @HwangTaehyun. While testing the app on the production, the lottie splasch screen gets skipped, and instead the default splash screen with the static image is showing. I am using expo bare flow and here is the AppDelegate.m file code

• (BOOL)application:(UIApplication )application didFinishLaunchingWithOptions:(NSDictionary )launchOptions {

  if defined(FB_SONARKIT_ENABLED) && __has_include(<FlipperKit/FlipperClient.h>)

  InitializeFlipper(application);

  endif

  RCTBridge bridge = [self.reactDelegate createBridgeWithDelegate:self launchOptions:launchOptions]; RCTRootView rootView = [self.reactDelegate createRootViewWithBridge:bridge moduleName:@"main" initialProperties:nil]; id rootViewBackgroundColor = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"RCTRootViewBackgroundColor"]; if (rootViewBackgroundColor != nil) { rootView.backgroundColor = [RCTConvert UIColor:rootViewBackgroundColor]; } else { rootView.backgroundColor = [UIColor whiteColor]; }

  self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds]; UIViewController *rootViewController = [UIViewController new]; rootViewController.view = rootView; self.window.rootViewController = rootViewController; [self.window makeKeyAndVisible];

  [super application:application didFinishLaunchingWithOptions:launchOptions];

  / lottie animation / Dynamic t = [Dynamic new]; UIView animationUIView = (UIView )[t createAnimationViewWithRootView:rootView lottieName:@"loading"]; // change lottieName to your lottie files name animationUIView.backgroundColor = [UIColor whiteColor]; // change backgroundColor // register LottieSplashScreen to RNSplashScreen [RNSplashScreen showLottieSplash:animationUIView inRootView:rootView]; // casting UIView type to AnimationView type AnimationView animationView = (AnimationView ) animationUIView; // play [t playWithAnimationView:animationView]; // If you want the animation layout to be forced to remove when hide is called, use this code [RNSplashScreen setAnimationFinished:true]; / lottie animation */

  return YES; }

And I have uploaded the AppDelegate.h file as well

import <Foundation/Foundation.h>

import <React/RCTBridgeDelegate.h>

import <UIKit/UIKit.h>

import <Expo/Expo.h>

@interface AppDelegate : EXAppDelegateWrapper

@end

@HwangTaehyun could you take a look and help me on this? Thanks again

[vivianmauer]

This happens because the application is calling the .hide() method and the animation doesn't have enough time to run

You can fix this by adding a setTimeout with the time of your animation

  useEffect(() => {
    setTimeout(() => {
      LottieSplashScreen.hide();
    }, 2500);
  }, []);

Hi @vivianmauer Thanks for your answer, I tried this but it didn't help me

[HwangTaehyun]

Wow, it's so weird.. I'll check it!

[cloudy-ninja]

Thank you so much for your reply

[cloudy-ninja]

Hi @HwangTaehyun Any update on this? Thanks

[HwangTaehyun]

@cloudy-ninja Hi, Could you try this one? It seems related to this. I developed this package without considering the expo, so this problem occurred... https://github.com/HwangTaehyun/react-native-lottie-splash-screen/issues/57

[cloudy-ninja]

@HwangTaehyun thanks for your suggestion, I will look into it 👍

[cloudy-ninja]

I just tried, but the issue is still happening

[HwangTaehyun]

@cloudy-ninja I have a question. Does your lottie animation not appears at all in production mode? I suspect the Lottie animation file is not bundled in production mode.

[HwangTaehyun]

These links would be helpful to you. It's such a difficult issue... 🥲

@HwangTaehyun Happy Lunar New Year! thanks again for your help, let me try with these solutions today

[cloudy-ninja]

Also, do you have some time to talk to me? If possible, I'd like to go through it together. I will pay for your time Thanks

[HwangTaehyun]

Yeah, but I don't know if I can be of great help. I don't know well about the bare expo. However, I also want to help you!

[cloudy-ninja]

Thank you so much! When do you have time today? I can match your time, here is my email msr.wn.327@gmail.com If you are Ok, we can schedule a google meeting

[HwangTaehyun]

Can I know your country or UTC? I live in Korea (UTC+9)

[cloudy-ninja]

Please let me know the meeting time in your timezone

[HwangTaehyun]

I'm okay with Tuesday 1/24, 4 pm-6 pm or Thursday 1/26 11 pm-1 am.

[cloudy-ninja]

What about 5 pm Tuesday? I am guessing it's after about 14hrs 40mins

[HwangTaehyun]

Ok! here is my email eeht1717@gmail.com.

[cloudy-ninja]

I just sent the invitation, can you please confirm it?

[HwangTaehyun]

Yeah, I confirmed that!

[cloudy-ninja]

Nice!

[HwangTaehyun]

@cloudy-ninja There's no problem in release mode! Could you follow the expo bare workflow in README.md? I test this expo@47.0.13

[HwangTaehyun]

@cloudy-ninja Did you work out?

[cloudy-ninja]

Hi @HwangTaehyun, I'm sorry for the very late reply. Yes, it worked by following the readme. I can say that this package is working smoothly on expo bare work flow. Thanks again for your hard works!
