重装Android Studio后Flutter项目Gradle运行报错（Exit code 1）

Problem Description #

After reinstalling Android Studio, I tried launching my Flutter app (lib\main.dart) in debug mode on my Redmi 4, but ran into this Gradle build failure:

Fixed It! Here's What Worked #

After digging into the issue, I identified two root causes:

• Slow/unstable network: Gradle couldn't resolve dependencies properly due to poor network speed
• Stale build files: Old cached files in the project's build directory were causing connection conflicts

To resolve the problem, I took these steps:

• Deleted the entire build folder inside the android directory of my Flutter project
• Switched to a stable network connection to ensure dependency resolution completes smoothly
• Restarted Android Studio and re-launched the app in debug mode

That fixed the bind exception, and the app ran successfully on my Redmi 4.
