研究方向

Look at the platform detection code in the Angular CDK, specifically the `@angular/cdk/platform` module. The bug is likely in the `getSupportedPlatforms()` function or similar logic that initializes the `ANDROID` property. The issue shows that `platform.ANDROID` always returns true, suggesting a flawed detection condition. Reproduce by logging the platform properties. A fix might involve correcting the user agent string check or ensuring only Android devices set the flag to true. Consider adding a unit test for platform detection.
