Proposal

Please re-state the problem that we are trying to solve in this issue.

A "No native ExponentConstants module found" warning is shown.

What is the root cause of that problem?

We don't link the expo-const module, so it's not found.

App/package.json

Lines 354 to 357 in c3d33fc

	"expo": {
	"autolinking": {
	"exclude": [
	"expo-constants",

expo-const is being used in expo-asset module and it's found in PlatformUtils file. However, all the properties that is being used inside the file doesn't exist even if we installed the expo-const.
https://github.com/expo/expo/blob/d576550145ede25dec3f6636bf260f7b05bec7a6/packages/expo-asset/src/PlatformUtils.ts#L32-L39

So, it's no different whether we include expo-const module or not. Here is the available properites from expo-const.

{"addListener": [Function addListener], "debugMode": true, "deviceName": "iPhone 15 Plus", "emit": [Function emit], "executionEnvironment": "bare", "getWebViewUserAgentAsync": [Function getWebViewUserAgentAsync], "isHeadless": false, "listenerCount": [Function listenerCount], "manifest": {"description": "New Expensify is the next generation of Expensify: a reimagination of payments based atop a foundation of chat.", "name": "new.expensify", "platforms": ["ios", "android", "web"], "sdkVersion": "51.0.0", "slug": "new.expensify", "version": "9.0.50-7"}, "platform": {"ios": {"buildNumber": "9.0.50.7"}}, "removeAllListeners": [Function removeAllListeners], "removeListener": [Function removeListener], "removeSubscription": [Function removeSubscription], "sessionId": "715902EE-F726-43EA-B204-6797A7E27318", "statusBarHeight": 54, "systemFonts": [listOfFontsTooLong]}

What changes do you think we should make in order to solve the problem?

We can suppress the warning. One way to do it is by suppressing it here.

App/src/App.tsx

Lines 48 to 53 in c3d33fc

	LogBox.ignoreLogs([
	// Basically it means that if the app goes in the background and back to foreground on Android,
	// the timer is lost. Currently Expensify is using a 30 minutes interval to refresh personal details.
	// More details here: https://git.io/JJYeb
	'Setting a timer for a long period of time',
	]);

'No native ExponentConstants module found',

OR

We can link the expo-const by remove it from the auto-link exclude list.

App/package.json

Lines 354 to 357 in c3d33fc

	"expo": {
	"autolinking": {
	"exclude": [
	"expo-constants",

@twisterdotcom Whoops! This issue is 2 days overdue. Let's get this updated quick!

[melvin-bot]

@twisterdotcom Huh... This is 4 days overdue. Who can take care of this?

[twisterdotcom]

Seems straightforward right? I haven't recreated this, so will lean on C+ too for this dev specific issue.

Downgrading as this isn't customer facing.

[mollfpr]

I'm assuming we exclude the expo-constants to reduce the binary size. I think we can suppress the warning like it proposed from @bernhardoj.

Proposal seems good, but question: why is this only getting reported and fixed now? The PR that added that code was merged 10 months ago. Did we just live with warning until @eVoloshchak decided to report it?
