"Failed to find Java version for 'C:\Windows\system32\java.exe"问题的解决方法
OS: Windows 7 x86 64bit
JDK installed: http://download.oracle.com/otn-pub/java/jdk/7u3-b05/jdk-7u3-windows-x64.exe
Option #1
Execute Android SDK installer
http://dl.google.com/android/installer_r17-windows.exe
Actual result - it can not find JAVA on the system.
Environment variable JAVA_HOME, PATH and recommendation from different forums about registry key didn't help (like here http://codearetoy.wordpress.com/2010/12/23/jdk-not-found-on-installing-android-sdk/)
Option #2
Execute tools/android.bat from
http://dl.google.com/android/android-sdk_r17-windows.zip
Actual result:
Failed to start with the error in console: "Failed to convert path to a short DOS path: C:\Windows\system32\java.exe"
How I fixed this:
In the file android-sdk-windows\tools\lib\find_java.bat
-for /f %%a in ('%~dps0\find_java.exe -s') do set java_exe=%%a
+for /f %%a in ('%~dps0\find_java.exe') do set java_exe=%%a
Suggestions - it is obvious that find_java.exe has a bug in conversion long names to short one (at least if no any conversion is required)
红字部分为解决方法，这种方法需要使用zip包的Android SDK，而不能使用exe格式的，然后在android-sdk-windows\tools\lib\find_java.bat
文件中：
-for /f %%a in ('%~dps0\find_java.exe -s') do set java_exe=%%a
+for /f %%a in ('%~dps0\find_java.exe') do set java_exe=%%a
然后再运行android.bat就可以了。
