-   **IMPORTANT:** First run takes 30-60 minutes as it builds for all architectures (armeabi-v7a, arm64-v8a, x86, x86_64).

 - Debug APKs: `build/outputs/apk/gplay/debug/` and `build/outputs/apk/fat/debug/`
 - Release APKs require signing configuration in `~/.gradle/gradle.properties`
 
-### Common Build Issues
-
-1. **Missing NDK or incorrect version:**
-   - Error: `ANDROID_NDK_ROOT not set` or native library missing
-   - Solution: Install NDK 27.0.12077973 and set ANDROID_NDK_ROOT environment variable
-
-2. **Submodules not initialized:**
-   - Error: Missing deltachat-core-rust files
-   - Solution: Run `git submodule update --init --recursive`
-
-3. **Gradle wrapper validation:**
-   - Always validate gradle wrapper before building: `./gradlew wrapper --gradle-version=current`
-   - Wrapper is validated in CI via `gradle/actions/wrapper-validation@v4`
-
-4. **Clean build issues:**
-   - If build fails, try: `./gradlew clean && scripts/ndk-make.sh && ./gradlew assembleDebug`
-   - Remove `build/` directory if clean doesn't work

-
-Before committing changes, always run:
-
-1. **Gradle wrapper validation:**
-   ```bash
-   ./gradlew wrapper --gradle-version=current
-   ```
-
-2. **Build verification:**

-### When to Rebuild Native Libraries
-
-Rebuild native libraries (`scripts/ndk-make.sh`) when:
-- Updating deltachat-core-rust submodule
-- Modifying anything in `jni/` directory
-- Changing NDK version
-- After `git clean -fdx` or fresh clone
-
-**DO NOT** rebuild native libraries for:
-- Pure Java/Kotlin code changes
-- Resource file changes
-- Gradle configuration changes (unless changing native library linking)
-- Documentation updates

-## CI/CD Workflows
-
-### Preview APK Workflow (.github/workflows/preview-apk.yml)
-
-Runs on every pull request to build and upload a preview APK:
-
-1. **Setup steps:**
-   - Checks out repository with submodules
-   - Validates Fastlane metadata
-   - Sets up Rust cache (working-directory: jni/deltachat-core-rust)
-   - Sets up Java 17 (Temurin distribution)
-   - Sets up Android SDK
-   - Caches Gradle dependencies
-   - Sets up NDK r27
-
-2. **Build process:**
-   ```bash
-   scripts/install-toolchains.sh && scripts/ndk-make.sh armeabi-v7a
-   ./gradlew --no-daemon -PABI_FILTER=armeabi-v7a assembleFossDebug
-   ```
-   Note: Builds only armeabi-v7a for faster CI builds
-
-3. **Output:** Uploads APK artifact to GitHub Actions
-
-### Important CI Considerations
-
-- Always validate Gradle wrapper before committing changes
-- Fastlane metadata must be valid (validated in CI)
-- Use `--no-daemon` flag for Gradle in CI environments
-- CI builds use FOSS flavor to avoid Google Services dependencies
-- Expected CI build time: 15-25 minutes for full workflow
