WIP: Add proper Android app wrapping the zop AI CLI #7

Copilot commented 2026年03月15日 10:06:26 +01:00 (Migrated from github.com)

A CLI binary cross-compiled for GOOS=android cannot be launched as an Android app. This adds a proper APK built via gomobile bind + Gradle, with a native Java chat UI.

Go library (internal/zoplib/)

New gomobile-compatible package exposing a single function:

funcQuery(apiKey,baseURL,model,systemPrompt,userPromptstring)(string,error)

gomobile bind maps this to zoplib.Zoplib.query(...) in Java. Wraps go-openai (already a dependency). 5 mock-server unit tests cover success, system-prompt handling, server errors, and empty-choices.

Android app (android/)

Minimal Gradle project targeting API 21+, compileSdk 34:

• MainActivity.java — scrollable conversation view + EditText/Button input; network calls on ExecutorService thread, UI updates via Handler(Looper.getMainLooper()); action-bar Settings dialog persists API key, base URL, model, and system prompt to SharedPreferences
• ZopUnitTest.java — JVM unit tests for app-layer logic
• app/libs/zoplib.aar is generated at build time (excluded from VCS)

CI/CD

• android.yml (new) — runs go test ./internal/zoplib/, installs NDK via sdkmanager, runs gomobile bind, builds debug APK with Gradle 8.7 + AGP 8.3.2, runs Android JVM tests, uploads APK artifact
• release.yml — new build-android job produces an unsigned release APK attached to GitHub Releases; removes the old GOOS=android CLI binary matrix entry (superseded)
• test.yml — updated android job now runs go test ./internal/zoplib/ alongside the existing cross-compile checks

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• dl.google.com
  • Triggering command: /usr/lib/jvm/temurin-17-jdk-amd64/bin/java /usr/lib/jvm/temurin-17-jdk-amd64/bin/java --add-opens=java.base/java.util=ALL-UNNAMED --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.lang.invoke=ALL-UNNAMED --add-opens=java.prefs/java.util.prefs=ALL-UNNAMED --add-opens=java.base/java.nio.charset=ALL-UNNAMED --add-opens=java.base/java.net=ALL-UNNAMED --add-opens=java.base/java.util.concurrent.atomic=ALL-UNNAMED -Xmx2048m -Dfile.encoding=UTF-8 -Duser.country -Duser.language=en -Duser.variant -cp /home/REDACTED/.gradle/wrapper/dists/gradle-8.4-bin/1w5dpkrfk8irigvoxmyhowfim/gradle-8.4/lib/gradle-launcher-8.4.jar -javaagent:/home/REDACTED/.gradle/wrapper/dists/gradle-8.4-bin/1w5dpkrfk8irigvoxmyhowfim/gradle-8.4/lib/agents/gradle-instrumentation-agent-8.4.jar org.gradle.launcher.daemon.bootstrap.GradleDaemon 8.4 -o ux_amd64/vet (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
