ANDROID_HOME fallback logic

[Tanish-Ranjan]

Android Components to be used by an Android project is configured via ANDROID_HOME environment variable. If the property doesn't exist then we are not providing the dependency in #173. This implementation can be improved via fallback logic similar to what we did for JAVA_HOME in #165

Hi @Tanish-Ranjan, I'm an AI Support assistant here to help with your issue. While the team reviews your request, I wanted to provide some possible tips and documentation that might help you in the meantime.

Suggestions

• Implement a multi‐step fallback for locating the Android SDK, mirroring Find compatible GradleJavaHome and notify client in case of incompatibility #165 (Java home fallback):

  • First check ANDROID_HOME, then ANDROID_SDK_ROOT / ANDROID_SDK.
  • Read sdk.dir from local.properties in the project root.
  • Attempt common default install paths:
    • Windows: %LOCALAPPDATA%/Android/sdk
    • macOS: ~/Library/Android/sdk
    • Linux: ~/Android/Sdk
  • Use the Android SDK Manager API (e.g. com.android.sdklib.AndroidSdkHandler) to validate/normalize the path.
  • If still not found, emit a clear warning or error.

• Review the Java fallback implementation in issue Find compatible GradleJavaHome and notify client in case of incompatibility #165 for patterns and utility methods you can reuse:
  • Find compatible GradleJavaHome and notify client in case of incompatibility #165

• For context on how Android components (like R.jar) are wired in, see the workaround discussion in Improve support for Android intermediate generated sources #181:
