jwinterm 083f8b7f2a CI: add Android build workflow (signed APK + AAB)
Mirrors the Linux workflow's approach — uses the Cake-Labs prebuilt
Docker image (Flutter 3.32.0 + NDK r28 + Go + Android SDK + JDK17 +
all native build deps) and the prebuilt monero_c .so bundle, so we
skip the multi-hour native cross-compile.

Stages monero + wownero .so files into android/app/src/main/jniLibs/
for all 4 Android ABIs (arm64-v8a, armeabi-v7a, x86, x86_64). Zano
libs in the bundle are ignored.

Decodes the upload keystore from secret ANDROID_KEYSTORE_BASE64,
writes android/key.properties (which build.gradle's signingConfigs
already reads), builds a universal release APK for sideload + an
AAB for Play Console. Both signed with the upload key; Play App
Signing re-signs the AAB server-side with the production key on
upload.

Required Gitea Actions secrets:
  ANDROID_KEYSTORE_BASE64
  ANDROID_KEYSTORE_PASSWORD
  ANDROID_KEY_ALIAS
  ANDROID_KEY_PASSWORD
  TROCADOR_API_KEY (already set, reused from Linux)
  TROCADOR_MONERO_API_KEY (same)
  TROCADOR_EXCHANGE_MARKUP (same)

mwebd (Litecoin MWEB privacy) is NOT built. LTC works without it,
just no MWEB feature. Add the build step + go build pipeline if we
want MWEB on Android — separate effort.

Artifacts:
  - hash-wallet-android-apk-<sha>  (single universal APK, 14-day retention)
  - hash-wallet-android-aab-<sha>  (Play Console upload, 30-day retention)

Hash Wallet

Hash Wallet (#) is an open-source, non-custodial, multi-currency crypto wallet for Android, iOS, macOS, Linux, and Windows. It is a fork of Cake Wallet maintained by Such Software LLC.

Why a fork?

Cake Wallet ended Wownero support in early 2026. Hash Wallet exists to keep Wownero as a first-class mobile experience, run by the project's founder, while shipping a slimmer, more focused multi-coin wallet without the chains and integrations we don't want to maintain or recommend.

Supported chains

  • Monero (XMR)
  • Wownero (WOW)
  • Bitcoin (BTC)
  • Litecoin (LTC), incl. MWEB
  • Bitcoin Cash (BCH)
  • Dogecoin (DOGE)
  • Nano (XNO)
  • Ethereum (ETH) + ERC-20s
  • Polygon (POL)
  • Base (BASE)
  • Arbitrum (ARB)
  • BNB Smart Chain (BSC)

Hardware wallet support: Ledger, Trezor, BitBox.

What's different from Cake Wallet

Removed:

  • Solana, Tron, Zano, Zcash, Decred (chain support disabled)
  • Lightning Network (deferred — running Greenlight infra is out of scope for now)
  • Cake Pay gift cards (Cake Labs–operated service)
  • All direct swap-provider integrations except Trocador, which already aggregates ChangeNow, FixedFloat, LetsExchange, Exolix, StealthEx, Quantex, and ~16 others under one privacy-friendly API

Replaced or planned:

  • Default Monero/Wownero/BTC node lists augmented with community nodes (don't rely on Cake Labs–operated nodes alone)
  • Fiat price API replacement (Cake's API → public source) — pending
  • Tor / Arti integration improvements — pending

Build instructions

The build system is unchanged from upstream Cake Wallet. See docs/ for per-platform instructions:

  • Android: docs/build_android.md
  • iOS: docs/build_ios.md
  • macOS: docs/build_macos.md
  • Linux: docs/build_linux.md
  • Windows: docs/build_windows.md

Required Flutter version is pinned in Dockerfile (currently 3.32.0) and .tool-versions. Newer Flutter SDKs (3.5+) drop the _macros pseudo-package that Cake's pinned hive_generator + build_resolvers transitively require — flutter pub get will fail until you switch to 3.32.0. If using asdf or mise, the version will be picked up automatically; otherwise:

git clone --depth 1 --branch 3.32.0 https://github.com/flutter/flutter.git ~/sdks/flutter/3.32.0
export PATH="$HOME/sdks/flutter/3.32.0/bin:$PATH"
flutter --version    # confirm 3.32.0 / Dart 3.8.0

Before the first flutter pub get, you must run the prep scripts to clone external native dependencies:

./scripts/prepare_torch.sh
./scripts/prepare_moneroc.sh
./scripts/build_bitbox_flutter.sh
# Then fetch the prebuilt reown_flutter tarball (CI does this; reproduce locally
# with the URL in .github/workflows/build-linux.yml).

Then run the platform-specific configure script, e.g.:

APP_LINUX_TYPE=cakewallet ./configure_hash_wallet.sh linux
