> Status: early development (milestone 1 of 9). Architecture and roadmap: [docs/ARCHITECTURE.md](docs/ARCHITECTURE.md) (German).

## Install

Install and update through [Obtainium](https://obtainium.imranr.dev) with the button above, or add
`https://git.mrblake.cc/MrBlake/Pixelwall` as an app source. Releases ship two APKs: pick `core`
(no network permission) or `full` with Obtainium's APK filter.

## Build variants

| Flavor | applicationId | Network |
|---|---|---|
| `core` | `org.pixelwall.app` | no `INTERNET` permission (enforced by `./gradlew check`) |
| `full` | `org.pixelwall.app.full` | `INTERNET` for the DNS filter and optional rule updates |

## Building

Requirements: JDK 21, Android SDK (platform 37).

```sh
./gradlew assembleCoreDebug      # debug APK without network access
./gradlew check                  # unit tests, lint, network permission check
```

## Releasing

Release APKs are signed with a key kept outside the repository. Configure it in `~/.gradle/gradle.properties`
(`pixelwall.signing.storeFile`, `.storePassword`, `.keyAlias`, `.keyPassword`); without it the release APKs are unsigned.

```sh
./gradlew dist                   # signed APKs in dist/ as pixelwall-<flavor>-v<version>.apk
```
