Demo build (Android)

pnpm build:android:demo makes a release build that runs on its own, with sample data built in, so you can try sign-in, the feed, likes and offline mode on a phone before you have a backend.

Before you start:

The build is for 64-bit ARM phones (almost every Android phone from the last few years).
It’s signed with the debug key unless you set up release signing, so it can’t go to Play.
It installs as the dev app (“BareshipApp Dev”), next to any staging or prod build.

Build it. The first build takes a while because the native code compiles in release mode:
Terminal window
```
pnpm build:android:demo
```
Install android/app/build/outputs/apk/dev/release/app-dev-release.apk. With the phone connected over USB, run the command below. Or copy the file to the phone and open it, and allow installs from that app when Android asks.
Terminal window
```
adb install -r android/app/build/outputs/apk/dev/release/app-dev-release.apk
```
Sign in with demo@example.com / password123.

The sample data resets every time the app starts; your sign-in and settings stay.

How it stays out of real releases

The demo build bundles index.demo.js, which starts the mock backend and hands it to the app through src/app/mock-backend.ts. Normal release bundles never include it:

Gradle refuses -PdemoBuild for the staging and prod environments.
scripts/ci/check-no-mocks-in-release.sh fails CI if mock code reaches a normal release bundle.

If something goes wrong

“App not installed” or a signature error: a dev build signed with a different key is already on the phone. Uninstall it, then install again.
The build stops with “-PdemoBuild only builds the dev flavor”: the demo build only exists for the dev environment. Use pnpm build:android:staging or pnpm build:android:prod for those.
