Kotlin counterpart of the iOS spike. Connect an external wallet (Reown AppKit Android) and have it sign a real eth_sendTransaction — an ERC-20 approve of the Autonomi payment vault (amount 0 → gas only). On a physical device this completes the signature end-to-end. - app/build.gradle.kts: com.reown:android-bom:1.4.1 + core + appkit - wallet/EthCalldata.kt: approve + payForQuotes (BigInteger) - wallet/AutonomiContracts.kt: Arbitrum chains + token/vault addrs - wallet/WalletConnectManager.kt: init/chains/ModalDelegate/request - MainActivity/MainScreen: configure + Compose wallet UI + modal - AndroidManifest: antdemo-wc:// deep-link return scheme - README: spike section + known unknowns Reown Android API written against docs; verify in Studio. Not a full paid upload (needs ant-ffi external-signer surface, V2-391). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Get AntAndroidDemo building with the WalletConnect spike:
- Add Gradle 8.9 wrapper (system Gradle 9.5.1 is incompatible with AGP 8.5.2)
- settings.gradle.kts: add JitPack repo (Reown pulls Scarlet, kethereum,
custom-qr-generator, multiformats from there)
- build.gradle.kts: material-navigation:1.7.6 (bottom-sheet navigator the
AppKit modal host needs; not in the Compose BOM)
- Correct the Reown AppKit Android API against the resolved appkit:1.4.1
(javap) + upstream sample/modal:
- CoreClient.initialize + AppKit.initialize + setChains from presets
- full 14-method ModalDelegate; response via onSessionRequestResponse
- getAccount().address/.chain; AppKit.request(Request(method,params),..)
- Compose modal is NavHost + appKitGraph + Web3Button (no AppKitComponent);
added AppRoot() hosting a bottom-sheet NavHost
BUILD SUCCESSFUL — debug APK (arm64-v8a incl.) assembles. Still needs a
Reown projectId in MainActivity and a physical device to run the
connect -> sign round-trip.

Runtime crash on launch: appkit 1.4.1's `appKitGraph` presents the modal
via Accompanist's navigation-material `bottomSheet {}`, but the NavHost had
registered the newer androidx material-navigation BottomSheetNavigator →
"Could not find Navigator with name BottomSheetNavigator". (appkit's
`develop` sample uses androidx; the 1.4.1 release still uses Accompanist.)
Swap to accompanist-navigation-material:0.34.0 (the version appkit pulls)
and use rememberBottomSheetNavigator + its ModalBottomSheetLayout.
Verified on a physical Galaxy S10 (Android 12) over wireless adb: app
launches, full UI renders, Reown "Connect wallet" (Web3Button) shown.

…on device Swap the temporary borrowed projectId for a dedicated mobile-SDK Reown projectId (public client identifier). Verified end-to-end on a physical Galaxy S10 (Android 12) over wireless adb: Connect wallet -> MetaMask approves session (account 0xc2..8691, chain eip155:42161 Arbitrum One) -> "Send test approve tx" -> MetaMask signs eth_sendTransaction -> app receives tx hash. Confirmed on-chain (Arbitrum One): ERC-20 approve(paymentVault, 0) on the ANT token, receipt status 0x1. This proves the external-signer flow (app builds calldata, external wallet signs, no embedded key) works on mobile — the store-policy-safe payment model. Note: the "Batch subscribe timed out" status is a benign Reown relay background timeout surfaced by Delegate.onError; not a tx failure. Follow-up polish: don't route relay-internal errors to the user-facing status line. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
…s + dark mode Rework AntAndroidDemo into a faithful facsimile of the desktop app (ant-ui): - Autonomi palette as Material3 dark+light schemes (ui/Theme.kt), lifted from ant-ui tailwind.config.cjs + main.css. ThemeController persists the choice. - Bottom navigation (mobile pattern): Uploads · Downloads · Wallet · Settings. Nodes intentionally omitted — nodes can't run on mobile. - Files split into two tabs (Uploads / Downloads) given limited screen width; rows mirror files.vue (name · status badge · size · cost · date, progress, mono address, saved-to). Wired to real dataPutPublic/dataGetPublic; seeded with mock rows so the lists look lived-in. - Wallet screen: external-signer connect (Web3Button) + payment test + mock balances. - Settings screen: bordered cards mirroring settings.vue; the Light Mode toggle is live (drives ThemeController, persisted); other cards are mock. Verified on a physical S10: all tabs render in both dark and light; the dark-mode toggle swaps the whole app live and survives relaunch.

… settings - Replace the Light Mode toggle with a "Screen mode" segmented control (Dark | Light), left=Dark right=Light, reflecting/driving ThemeController. - Remove Settings cards that don't apply on mobile: Storage Directory, Downloads Directory (not user-settable), and the Node daemon version in About (no daemon on mobile).

Bump the bundled AAR to the external-signer surface and route uploads through it when a wallet is connected: - FilesStore.upload: if a WalletConnect wallet is connected, run prepare_data_upload → wallet signs approve + payForQuotes (via WalletConnectManager.sendTransaction + EthCalldata) → finalize_upload, driving the Quoting → AwaitingApproval → Paying → Uploading → Complete states. Falls back to the devnet single-shot dataPutPublic otherwise. - EVM token/vault addresses for the calldata are read from the on-device devnet manifest (parseManifestEvm). - WalletConnectManager: generalized to sendTransaction(to, data); sendApprove now delegates to it. - app/libs/ant-android-release.aar: rebuilt from ant-sdk feat/ffi-external-signer. Compiles + launches on the S10. NOTE: completing the payment on-chain requires the connected wallet to be on the same chain as the devnet payment vault (MetaMask-on-Arbitrum vs local Anvil) and a reachable devnet — documented caveats; not yet run end-to-end.

…igner client - autonomi:// deep-link support: AntUri parser ports ant-webex's parseAntUri / buildFilename / sanitizeFilename (name + filetype → name.filetype, address- derived fallback), plus an explicit `filename` param override. VIEW intent on the autonomi scheme → download the address (with the resolved filename) and jump to the Downloads tab (singleTask + onNewIntent + DeepLinkNav bus). - External-signer uploads now use the wallet-free connectFromDevnetManifestExternalSigner (works with the Sepolia devnet). - FilesStore.download accepts a suggested filename (deep-link supplied). - Bump bundled AAR to latest ant-core (0.2.9) build. Verified on the S10: firing autonomi://<addr>?name=quarterly-report&filetype=pdf opens the app, shows Downloads with a "quarterly-report.pdf" row, and starts the fetch (fails only when no devnet manifest is present).

AntAndroidDemo consumer app for the external-signer flow (app builds calldata, user's self-custody wallet signs — no embedded key). Verified connect→sign end-to-end on a real Galaxy S10: - two-step quote→approve upload with a cost/visibility confirm dialog - real per-stage % progress via the FFI ProgressListener callback - Public/Private visibility; Private saves a re-downloadable datamap - Downloads: one field + attach-datamap + Download (autonomi:// or datamap) - approve→confirm receipt-poll; explicit gas fields on sendTransaction - autonomi:// deep links (AntUri); first-sign relay warm-up auto-retry Consumes new ant-ffi surface from ant-sdk #199 (via the release AAR). Stops tracking app/libs/ant-android-release.aar (27MB) — ships via the ant-sdk release, gitignored. Blocked on that release. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
