Question

Can anyone please confirm if android development is not yet supported on windows 7 x64? I downloaded the sdk, but when I tried to launch the sdk and avd manager it fails to

Answer 1

For me the problem was solved on windows 8 64 by editing the find_java.bat in the android_sdk/tools/lib folder.

Basically the for loops that set java_exe and javaw_exe will not work correctly if the path has a white space in it! Ie. "C:\Program Files\Java\jdk" has this, find_java.bat will set java_exe to "C:\Program" which android.bat doesn't like.

I was ok when i edited find_java.bat like this: (see the two lines after 'rem edit:)

rem Check we have a valid Java.exe in the path. The return code will
rem be 0 if the command worked or 1 if the exec failed (program not found).
for /f %%a in ('%~dps0\find_java.exe -s') do set java_exe=%%a
rem edit:
set java_exe="%JAVA_HOME%\bin\java.exe"
if not defined java_exe goto :CheckFailed

:SearchJavaW
rem Check if we can find a javaw.exe at the same location than java.exe.
rem If that doesn't work, just fall back on the java.exe we just found.
for /f %%a in ('%~dps0\find_java.exe -s -w') do set javaw_exe=%%a
rem edit:
set javaw_exe="%JAVA_HOME%\bin\javaw.exe"
if not exist %javaw_exe% set javaw_exe=%java_exe%
goto :EOF

HTH

What worked for me was adding the JAVA_HOME environment variable pointing to the jdk folder (in my case c:\Program Files\Java\jdk1.7.0_04) and adding %JAVA_HOME%\bin to PATH variable

As one of the comments indicated its C:\android-sdk-windows\tools\lib\find_java.exe and find_java.bat to blame. I have Win7-64bit, no 32bit JavaJRE/JDK installs, one jre7 64bit install. Find_java.bat+exe tool cannot find proper path to 64bit version. I guess you're fine if only 32bit JRE was installed (did not try this).

• Open DOS console and goto folder C:\android-sdk-windows\tools\lib\
• run find_java.bat and find_java.exe, you should get "failed to convert path..." and "c:\windows\system32\java.exe" printouts
• type command set path=c:\Program Files\Java\jre7\bin;%path%
• run find_java.bat and find_java.exe, you don't get any errors and proper path to c:/program files/java/jre7/bin/java.exe is printed

If you don't want to mess with Control Panel's environment prefs you could create two batch scripts to run AVD and SDK Manager.

C:\android-sdk-windows\AVD Manager.bat

set PATH=C:\Program Files\Java\jre7\bin;%PATH%
"AVD Manager.exe"

C:\android-sdk-windows\SDK Manager.bat

set PATH=C:\Program Files\Java\jre7\bin;%PATH%
"SDK Manager.exe"

This problem and fix was tested on Win7-64bit/Android SDK Tools 20.0.3/Android SDK Platform-tools 14 releases.
