Android Studio新手求助：加载Build Tools 25.0.1失败问题

Hey there! I’ve dealt with this exact error when I was starting out with Android Studio, so let me share some practical fixes that worked for me and other developers:

• Double-check if Build Tools 25.0.1 is actually installed
  Open Android Studio and go to File > Settings > Appearance & Behavior > System Settings > Android SDK (on Windows/Linux; for Mac, it’s Android Studio > Settings > ...). Switch to the SDK Tools tab, tick the Show Package Details box at the bottom-right, then expand Android SDK Build-Tools. Make sure the 25.0.1 version is checked. If it’s missing or looks like the installation was incomplete, re-check it and click Apply to reinstall.

• Update or explicitly set the Build Tools version in your project
  Open your module-level build.gradle file (the one inside your app folder, not the root project file). Look for the line buildToolsVersion "25.0.1":

  • If you confirmed 25.0.1 is installed, keep it and sync your project (click the Sync Now button in the top-right).
  • If you have a newer, stable Build Tools version installed (like 28.0.3 or higher), replace "25.0.1" with that version number, then sync.

• Invalidate caches and restart Android Studio
  Caches can sometimes cause weird recognition issues. Go to File > Invalidate Caches..., select Invalidate and Restart, and let Studio reboot. After it comes back up, sync your project again—this often clears up build tool loading errors.

• Verify your SDK path is correct
  Back in the Android SDK settings page, check that the Android SDK Location points to the correct folder where you installed your SDK. If you moved the SDK folder recently or changed paths, this could break the link. Click Edit to select the right directory, then sync your project.

• Manually repair the Build Tools folder (last resort)
  Navigate to your SDK installation directory, open the build-tools folder, and look for the 25.0.1 subfolder. If it’s missing, reinstall via SDK Manager. If it exists but has missing files, delete the entire 25.0.1 folder, then go back to SDK Manager to reinstall the version.
