⚔ SabreTooth IDE

Lightweight Android IDE for APK generation — no bloat, no Gradle sync, no layout editor.

Package: com.vitalsoft.sabretooth
Version: 1.0.0
Platform: Cross-platform (Windows, macOS, Linux)
Requires: Java 21+

---

Overview

SabreTooth IDE is a minimalist Android development environment focused on one thing: getting your code compiled into a valid APK as fast as possible. It supports both Gradle-based and Eclipse-style project structures, automatically detects your installed tools, and keeps all configuration in a simple .sabreconf file per project.

No Gradle sync. No layout editor. No 5-minute startup. Just open, edit, build.

Features

• Dark IDE UI — Android Studio-inspired layout: project tree, tabbed editor, console, menu bar
• Syntax highlighting — Java, Kotlin, XML, Groovy, Gradle, Properties files
• Auto-indentation — Smart indent on Enter/Tab, brace-aware
• Project types — Gradle (standard) and Eclipse-style projects
• APK build — Debug and release APK via Gradle; cancel mid-build
• Tool auto-detection — Finds all installed Gradle versions, JDKs, and Android SDK
• .sabreconf per project — Stores build config: SDK versions, paths, signing, extra Gradle args
• Find & Replace — With case sensitivity and replace-all
• File tree — With context menu (new file, new dir, rename, delete)
• New Project wizard — Configures min/target/compile SDK, package name, Gradle, JDK
• Recent projects — Quick re-open from File menu
• Tabs with close — Middle-click or × button; unsaved-change prompts
• Status bar — Line/column, language, build status, project name
• Font size zoom — Ctrl+/Ctrl-
• Keyboard shortcuts — Full set, see below

Project Configuration: .sabreconf

Every project managed by SabreTooth has a .sabreconf file in its root. Example:

# SabreTooth IDE Project Configuration

[project]
project.name = MyApp
project.package = com.example.myapp
project.type = gradle
android.mainActivity = MainActivity

[android]
android.minSdk = 21
android.targetSdk = 34
android.compileSdk = 34
android.versionCode = 1
android.versionName = 1.0

[build]
build.type = debug
build.gradlePath = /usr/local/bin/gradle
build.jdkPath = /usr/lib/jvm/java-21-openjdk-amd64
build.androidJar = /home/user/Android/Sdk/platforms/android-34/android.jar
build.outputDir = build/outputs/apk
build.extraGradleArgs = --stacktrace

[signing]
sign.keystorePath = /path/to/my.jks
sign.keystoreAlias = mykey

You can edit this file directly or use Project → Project Settings.

Supported Project Structures

Gradle (recommended)

MyApp/
├── .sabreconf
├── settings.gradle
├── build.gradle
└── app/
    ├── build.gradle
    └── src/main/
        ├── AndroidManifest.xml
        ├── java/com/example/myapp/
        │   └── MainActivity.java
        └── res/
            ├── layout/activity_main.xml
            └── values/strings.xml

Eclipse

MyApp/
├── .sabreconf
├── AndroidManifest.xml
├── project.properties
├── .classpath
└── src/com/example/myapp/
    └── MainActivity.java

---

Build Process

1. Save All — All open files are saved before any build
2. Gradle invoked — Using the path from .sabreconf (or auto-detected gradlew/system gradle)
3. JDK override — If a JDK path is set, JAVA_HOME is set for that process
4. Output streamed — Console shows real-time output with color coding
5. APK located — On success, SabreTooth finds the APK and offers to open its folder

For release builds, set up your keystore in Project Settings → Signing. You'll need to configure the signing config in your build.gradle manually (SabreTooth sets up the paths, Gradle does the signing).

---

Extra Gradle Arguments

You can pass arbitrary extra arguments to Gradle via .sabreconf:

build.extraGradleArgs = --stacktrace --info

Or per-task via the Project Settings dialog under Build Tools.

---

IDE Preferences

Stored in ~/.sabretooth/ide.conf:

• Font size, tab size, line numbers, word wrap
• Default Android SDK root
• Default Gradle installation
• Default JDK
• Gradle user home directory
• Window position/size

---
