# Build Script Design
|
|
|
|
## Problem
|
|
|
|
Building the app requires Android Studio or memorizing Gradle commands. Sharing signed APKs with friends requires keystore setup and signing configuration. This is friction that a simple interactive script can eliminate.
|
|
|
|
## Solution
|
|
|
|
A single `build.sh` bash script at the project root that provides an interactive terminal menu for building, signing, and outputting APKs.
|
|
|
|
## Design
|
|
|
|
### Main Menu
|
|
|
|
```
|
|
╔══════════════════════════════════╗
|
|
║ Radio 247 Build Tool ║
|
|
╚══════════════════════════════════╝
|
|
|
|
What would you like to do?
|
|
|
|
1) Build Release APK (signed, shareable)
|
|
2) Build Debug APK (quick, for testing)
|
|
3) Manage Keystore (create or check signing key)
|
|
4) Clean (remove build artifacts)
|
|
5) Exit
|
|
```
|
|
|
|
### Build Flow — Release
|
|
|
|
1. Check for keystore at `keystore/radio247-release.jks` — if missing, redirect to keystore creation
|
|
2. Prompt for keystore password (hidden input)
|
|
3. Run `./gradlew assembleRelease` with signing injected via CLI properties
|
|
4. Copy signed APK to `dist/` with descriptive filename
|
|
5. Print path and file size
|
|
|
|
### Build Flow — Debug
|
|
|
|
1. Run `./gradlew assembleDebug`
|
|
2. Copy APK to `dist/`
|
|
3. Print path
|
|
|
|
### Keystore Management
|
|
|
|
- Stored at `keystore/radio247-release.jks` (gitignored)
|
|
- Created via `keytool` (ships with JDK)
|
|
- Prompts: name, optional organization, password (with confirmation)
|
|
- Key alias: `radio247`
|
|
- Validity: 10,000 days
|
|
|
|
### Signing Method
|
|
|
|
Signing config is injected via Gradle command-line properties rather than modifying `build.gradle.kts`:
|
|
|
|
```bash
|
|
./gradlew assembleRelease \
|
|
-Pandroid.injected.signing.store.file=keystore/radio247-release.jks \
|
|
-Pandroid.injected.signing.store.password=<password> \
|
|
-Pandroid.injected.signing.key.alias=radio247 \
|
|
-Pandroid.injected.signing.key.password=<password>
|
|
```
|
|
|
|
This keeps secrets out of version control and build files clean.
|
|
|
|
### Output
|
|
|
|
- Directory: `dist/` at project root (auto-created, gitignored)
|
|
- Naming: `radio247-v{versionName}-{buildType}.apk`
|
|
- Example: `radio247-v1.0-release.apk`
|
|
- Same version+type overwrites previous file
|
|
|
|
### Pre-flight Checks
|
|
|
|
- `java` or `JAVA_HOME` available
|
|
- `./gradlew` exists and is executable
|
|
- Keystore exists (for release builds)
|
|
|
|
### Error Handling
|
|
|
|
- Build failures show last ~20 lines of Gradle output with colored error banner
|
|
- Non-zero exit codes propagated
|
|
- Password never written to disk or logged
|
|
|
|
### Gitignore Additions
|
|
|
|
- `dist/`
|
|
- `keystore/`
|
|
|
|
## Decisions
|
|
|
|
| Aspect | Choice | Rationale |
|
|
|--------|--------|-----------|
|
|
| Language | Bash | Zero dependencies, macOS ships with it |
|
|
| Interface | `select` menu | Built-in, no external tools needed |
|
|
| Signing | CLI properties | Keeps build.gradle.kts clean, secrets out of git |
|
|
| Keystore location | `keystore/` dir | Separate from source, easy to gitignore |
|
|
| Output location | `dist/` | User preference, clear separation from build artifacts |
