This PR attempts to improve clarity of androids section of `flutter doctor -v` output by providing explicit information about which JDK is being used and how to configure a different one if needed. ### Before ```console • Java binary at: /Users/user/Applications/Android Studio Ladybug Feature Drop 2024.2.2 Canary 2.app/Contents/jbr/Contents/Home/bin/java ``` ### After 1. When JDK is from Android Studio: ```console • Java binary at: /Users/users/Applications/Android Studio Ladybug Feature Drop 2024.2.2 Canary 2.app/Contents/jbr/Contents/Home/bin/java This is the JDK bundled with latest Android Studio installation To manually set a custom JDK path, use: `flutter config --jdk-dir="path/to/jdk"` ``` 2. When JDK is from JAVA_HOME env variable: ```console • Java binary at: /Users/user/Applications/Android Studio Ladybug Feature Drop 2024.2.2 Canary 2.app/Contents/jbr/Contents/Home/bin/java This JDK is specified by JAVA_HOME environment variable To manually set a custom JDK path, use: `flutter config --jdk-dir="path/to/jdk"` ``` 3. When path to JDK is set in flutter config: ```console • Java binary at: /Users/user/Applications/Android Studio Ladybug Feature Drop 2024.2.2 Canary 2.app/Contents/jbr/Contents/Home/bin/java This JDK was found in system PATH To change current JDK, run: `flutter config --jdk-dir="path/to/jdk"` ``` 4. When java binary is found in PATH (as fallback) ```console • Java binary at: /Users/user/Applications/Android Studio Ladybug Feature Drop 2024.2.2 Canary 2.app/Contents/jbr/Contents/Home/bin/java This JDK is specified in Flutter configuration To manually set a custom JDK path, use: `flutter config --jdk-dir="path/to/jdk"` ``` ### Motivation I think it's described in https://github.com/flutter/flutter/issues/153156#issuecomment-2336814991. TLDR; many developers struggle with Java-related issues and more verbose doctor's output will (presumably) improve DX in that part. fixes #153156 ## Pre-launch Checklist - [x] I read the [Contributor Guide] and followed the process outlined there for submitting PRs. - [x] I read the [Tree Hygiene] wiki page, which explains my responsibilities. - [x] I read and followed the [Flutter Style Guide], including [Features we expect every widget to implement]. - [x] I signed the [CLA]. - [x] I listed at least one issue that this PR fixes in the description above. - [x] I updated/added relevant documentation (doc comments with `///`). - [x] I added new tests to check the change I am making, or this PR is [test-exempt]. - [x] I followed the [breaking change policy] and added [Data Driven Fixes] where supported. - [x] All existing and new tests are passing.
