📝 Walkthrough

Walkthrough

The mobile showcase defines shared dev-client URL flags for onboarding, the floating action button, and automatic launch. iOS and Android launch URLs include the flags. Android retains its gesture and key-command preferences. The iOS launch instructions describe the URL options.

Changes

Mobile dev-client launch flags

Layer / File(s)	Summary
Define shared launch flags `scripts/mobile-showcase.ts`	The script defines URL flags to disable onboarding, the floating action button, and automatic launch.
Apply flags to platform launches `scripts/mobile-showcase.ts`, `.agents/skills/test-t3-mobile/SKILL.md`	iOS and Android launch URLs include the shared flags. The iOS instructions describe when to add URL parameters. Android retains its gesture and key-command preferences in its preferences file.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Refactor

Suggested reviewers: t3dotgg

Merge Risk: 🟡 Moderate · up to 15513

The Android screenshot harness launch can break because the URL is not quoted for the device shell, so captures would lose their flags and scene extras. The iOS dev-menu suppression flags may also be placed where the dev client does not read them. This only affects the developer showcase tooling, but the Android quoting should be fixed before merge.

Put the flags in the nested Metro URL.

Appending these values to <printed-dev-client-url> adds them to the dev-client deep link. It does not add them to the manifest URL carried by its encoded url parameter. The dev client will not receive the suppression flags through the path used by scripts/mobile-showcase.ts.

Update the instruction to decode the url parameter, append disableOnboarding=1, disableAutoLaunch=1, and disableFab=1 to that Metro URL, then encode it again.

Approvability

Verdict: Approved at 36d8093

Macroscope's review found this PR approvable — The PR only changes the mobile screenshot harness, replacing simulator preference writes with explicit SDK 58 dev-client launch flags and retaining unrelated gesture settings. Its runtime effects are confined to automated capture devices and generated screenshots, with no shipped product behavior or production configuration changed.

Notes:

Diff unchanged. Approvability was decided on eligibility alone.

No code changes detected at e017645. Prior analysis still applies.

official Expo dev launcher deep link disableFab disableAutoLaunch disableOnboarding URL parameters SDK 58

💡 Result:

<search_synthesis> In Expo SDK 58, you can control the behavior of the development launcher using URL query parameters when launching a development build, particularly for automation or end-to-end testing scenarios [1][2]. The following URL parameters can be added to the development client deep link to modify its behavior [2]: - disableOnboarding=1: Skips the onboarding screen that appears on the first launch of a development build [2]. - disableFab=1: Hides the floating Tools button (which is used to open the dev menu) [2]. - disableAutoLaunch=1: Prevents the dev menu from automatically opening when the app starts [2]. These parameters should be added to the development-client deep link itself, alongside any url parameter you may be providing [2]. For example, when launching via automation, you might construct a URL that includes these parameters to ensure the environment is configured correctly without user intervention [2]. Note that disableFab and disableAutoLaunch update the saved dev menu settings on the device, allowing these configurations to persist until manually changed in the dev menu [2]. Additionally, if you are using config plugins (Continuous Native Generation) in your project, you can configure these settings at build time in your app.json (or app.config.js) using the expo-dev-client plugin [3][4]: { "plugins": [ [ "expo-dev-client", { "skipOnboarding": true, "showMenuAtLaunch": false } ] ] } - skipOnboarding: Maps to the build-time equivalent of disabling the onboarding popup [5][4]. - showMenuAtLaunch: Can be set to false to suppress the automatic opening of the dev menu [5][4]. </search_synthesis>

When launching an update URL in a development build on an emulator or simulator using automation, such as in a CI/CD workflow, you can add the `disableOnboarding=1` query parameter to the URL to skip the onboarding screen that appears on the first launch of a development build after installation. ... #### App-specific deep links ... When testing deep links in your development build, such as when navigating to a specific screen in an Expo Router app or testing redirecting back to your app during an Oauth login flow, construct the URL exactly as you would if you were deep-linking into a standalone build of your app (for example, `myscheme://path/to/screen`). ... Your project must be already open in the development build for an app-specific deep link to work. Cold-launching a development build with an app-specific deep link is not currently supported.

🌐 Web query:

site:github.com/pingdotgg/t3code/blob/main/scripts/mobile-showcase.ts "DEV_CLIENT_LAUNCH_FLAGS" OR "metroUrl" OR "android"

💡 Result:

The file contains:

DEV_CLIENT_LAUNCH_FLAGS: no match found. [1]
metroUrl:
- iOS: http://${metroHost}:${config.metroPort}?disableOnboarding=1
- Android: encoded http://127.0.0.1:${config.metroPort}?disableOnboarding=1 [2]

Android launch uses:

1	adb shell am start -W \
2	-a android.intent.action.VIEW \
3	-d "t3code://expo-development-client/?url=${metroUrl}" \
4	--es showcasePairingUrl ... \
5	--es showcaseScene ... \
6	--es showcaseTheme ... \
7	com.t3tools.t3code

[2]

The Android package is com.t3tools.t3code; Metro is exposed through adb reverse. [2]

Put the dev-menu flags on the development-client deep link. metroUrl currently appends disableFab=1 and disableAutoLaunch=1 to the nested Metro URL. Expo SDK 58 reads these flags from the outer development-client deep link, next to its encoded url parameter. The current placement leaves the floating Tools button visible and allows the dev menu to open automatically. Keep disableOnboarding=1 in the encoded Metro URL, and move the other two parameters to the outer deep link. The Android path builds a separate URL, so this specific construction does not affect Android.

Put disableFab and disableAutoLaunch on each outer development-client deep link. These flags do not take effect when they are included in the URL-encoded manifest URL. This can leave the Tools button visible or open the dev menu during captures.

scripts/mobile-showcase.ts#L984-L986: retain only disableOnboarding=1 in the manifest URL, then construct an outer iOS development-client URL with disableFab=1 and disableAutoLaunch=1.
scripts/mobile-showcase.ts#L1253-L1255: retain only disableOnboarding=1 in metroUrl, then append disableFab=1 and disableAutoLaunch=1 to the outer Android URL at Line 1265.

Quote the Android URL for the remote shell.

runAdb passes the argument array directly to adb. The remote adb shell joins shell arguments with spaces without escaping them. Each literal & starts a separate command, so am start loses the launch flags and showcase extras.

metroUrl is encoded with encodeURIComponent; its inner ? becomes %3F, and it contains no literal &. The outer launch URL still contains unquoted & separators.
