-echo WARNING: Java not found in your path.

-rem The strategy is to look for Java under these 3 locations:

-rem - %ProgramFiles%, which may point to either a 32-bit or 64-bit install

-rem                   depending on the current invocation context

-rem - %ProgramW6432%, which points to a 32-bit install. This may not be defined.

-rem - %ProgramFiles(x86)%, which points to a 64-bit install. This may not be defined.

-

-if not defined ProgramFiles goto :Check64

-echo Checking if Java is installed in %ProgramFiles%\Java.

-set java_exe=

-for /D %%a in ( "%ProgramW6432%\Java\*" ) do call :TestJavaDir "%%a"

-echo.

-echo ERROR: No suitable Java found. In order to properly use the Android Developer

-rem ---------------

-:TestJavaDir

-rem This is a "subrountine" for the for /D above. It tests the short version

-rem of the %1 path (i.e. the path with only short names and no spaces).

-rem However we use the full version without quotes (e.g. %~1) for pretty print.

-echo.

-echo Java was found at %full_path%.

-echo Please consider adding it to your path:

-echo - Under Windows XP, open Control Panel / System / Advanced / Environment Variables

-echo - Under Windows Vista or Windows 7, open Control Panel / System / Advanced System Settings / Environment Variables

-echo At the end of the "Path" entry in "User variables", add the following:

-echo   ;%full_path%

-echo.

-goto :EOF

-

-rem ---------------

-:SearchJavaW

-rem Called once java_exe has been set. Try to see if we can find a javaw

-rem to use. If not, we'll default to using java_exe.

-for %%a in (%java_exe%) do set p=%%~pa

-for %%a in (%java_exe%) do set n=%%~na
