Windows10 x64安装Android SDK命令行工具25.2.3提示Java未找到求助

Hey there, let's tackle this installation issue together. Since you're working with the command-line version (no GUI wizard), we'll focus on environment variable checks and command-line-specific fixes. Here's what to try:

1. Verify Java Version Compatibility First #

Android SDK 25.2.3 requires Java 8 (either Oracle JDK or OpenJDK 1.8.x). Newer Java versions (9+) aren't compatible with this older SDK release.

• Open a command prompt and run these commands to check your current Java version:

  java -version
  javac -version
  

• Both should output something like 1.8.0_XXX. If you have a newer version installed, you'll need to install Java 8 and adjust your environment variables to point to it.

2. Double-Check Your Java Environment Variables #

Even if you set JAVA_HOME and JRE_HOME, small misconfigurations can break things:

• JAVA_HOME must point to the root directory of your JDK 8, not the bin folder. For example:
  C:\Program Files\Java\jdk1.8.0_291 (not C:\Program Files\Java\jdk1.8.0_291\bin)
• JRE_HOME should point to the root of your JRE 8:
  C:\Program Files\Java\jre1.8.0_291
• Add both %JAVA_HOME%\bin and %JRE_HOME%\bin to your system Path variable, and move them to the top of the Path list to avoid conflicts with other Java installations.
• Verify the variables are set correctly by running these commands in a new command prompt:

  echo %JAVA_HOME%
  echo %JRE_HOME%
  

  They should output the exact paths you set.

3. Configure Android SDK Environment Variables & Path #

1. Make sure you've extracted the Android SDK command-line tools (android-sdk_r25.2.3-windows.zip) to a directory without spaces or special characters (e.g., C:\Android\android-sdk instead of C:\Program Files\Android SDK).
2. Set a new system variable ANDROID_HOME pointing to this extracted root directory:
   C:\Android\android-sdk
3. Add these two paths to your system Path variable:
   • %ANDROID_HOME%\tools
   • %ANDROID_HOME%\platform-tools
4. Always open a new command prompt window after modifying environment variables—old windows won't pick up the new settings.

4. Test the Installation #

Run this command in the new command prompt to see if the SDK tools work:

android list sdk

If this runs without errors and shows a list of available SDK packages, you're good to go.

Common Fixes for Persistent Issues #

• Permission Problems: Right-click the command prompt and select "Run as administrator"—some SDK operations require elevated privileges.
• Antivirus Interference: Temporarily disable your antivirus software, as it might block SDK files from being accessed or executed.
• Corrupted SDK Download: If you still get errors, re-download the android-sdk_r25.2.3-windows.zip file from the official archive to rule out a corrupted download.

If you can share the exact error message from your screenshot, we can narrow this down even further—but these steps should resolve most common command-line installation issues with this SDK version.
