Android SDK Manager 가 실행되지 않을 때..

문제는 tools/lib/find_java.bat 파일의 문제..

find_java.bat 를 메모장 등으로 열어서..

아래의 %arch_ext%  부분을 자신의 OS 플랫폼(32, 64) 에 맞게 바꾼다.

즉, 32bit 윈도우면..  find_java%arch_ext%.exe ==> find_java32.exe
64bit 윈도우면.. find_java%arch_ext%.exe ==> find_java64.exe

두군데 모두 바꿔주면 잘 된다..

결국 ANDROID_SWT, JAVA_HOME 등의 환경변수 문제가 아니었어..
