# Android Studio Android Studio is built on IntelliJ IDEA. 2025 versions (Narwhal/Otter) feature **Gemini** for code generation and crash analysis. ## When to Use - **Android Apps**: Native Android development (Kotlin/Java). - **Compose**: "Live Edit" allows UI updates in real-time on devices/emulators. - **Profiling**: Inspecting memory leaks and battery usage. ## Core Concepts ### Gradle The build system. `build.gradle.kts` (Kotlin DSL) is the standard in 2025. ### Emulator Virtual Android device. 2025 emulators are resizable and support foldable postures. ### Logcat v2 The logging window. Colored, filterable, and queryable logic. ## Best Practices (2025) **Do**: - **Use Gemini**: "Explain this crash" in Logcat sends the stack trace to Gemini for analysis. - **Use Baseline Profiles**: Generate profiles to improve app startup time. - **Use App Quality Insights**: View Crashlytics issues directly in the IDE code editor. **Don't**: - **Don't hardcode Strings**: Use `strings.xml`. The IDE warns you for a reason. ## References - [Android Studio User Guide](https://developer.android.com/studio/intro)
