Android SDK installation doesn't find JDK is not the same release as this, and the solution "back" then "next" doesn't work.

I have tried installing various versions of Java and nothing seems to be working. I've been trying to get this installed for the last 3 days. Solutions I have tried that do NOT work:

  • Pushing the back button then the next button.
  • Adding an Environment Variable for JAVA_HOME that points to the System32 path and the actual java install directory.
  • Installing various versions of Java. (Java 6 and Java 7)

The install file is called installer_r20.0.3-windows and is the current exe available at http://developer.android.com/sdk/index.html

Error Message java.exe

  • what happens when you fire javac at your command prompt ? Commented Aug 21, 2012 at 3:35
  • It gave an error. After that, I added C:\Program Files\Java\jdk1.6.0_34\bin to the "Path" env var and it now works in command prompt, but the installer still doesn't work. Commented Aug 21, 2012 at 3:39
  • can you print the path variable's value ? Commented Aug 21, 2012 at 3:39
  • I should mention that this is a brand new installation of Windows 7 on a brand new PC. (Installed 3 days ago) C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files\TortoiseSVN\bin;C:\Program Files\Java\jdk1.6.0_34\bin Commented Aug 21, 2012 at 3:40

Ok, looking at to your JAVA_HOME path which is C:\Program Files\Java\jdk1.6.0_34\bin I suggest you to change it as C:\Program Files\Java\jdk1.6.0_34\. There is no need to add bin folder's path in the JAVA_HOME Path.

On my Win7 Ultimate 64 bits/ i need multiple things

  1. Set SystemEnvironment Variable JAVA_HOME = C:\Program Files\Java\jdk1.7.0_07
  2. Add the same value to SystemEnvironment Variable PATH, but make sure to put it before system32 path PATH = C:/Program Files/Java/jdk1.7.0_07;C:\Windows\system32; ....... (... = current value)
  3. and most important , i guessed. Rename c:\windows\system32\java.exe -> c:\windows\system32\java.exe.old
  4. Restart the installer (my case = installer_r20.0.3-windows.exe )

Voila!

This might help safe other's time

what's the point of renaming java.exe to java.exe.old? this method worked but I can't understand the reason behind renaming...
@saji159 I would guess that renaming it does two things: 1) It makes the java.exe not get called first when "java" is called and it preserves the backup / old java.exe.

Setting JAVA_HOME environment variable in System variable to C:\Program Files\Java\jdk1.7.0_07\ did solve my problem.

A couple of points to note.

  1. No need to specify bin or jre folder name.
  2. You will need to cancel and restart the Android SDK installation. Previous/Next may not work.
  3. I just copied the folder name from Windows explorer address bar. No need to replace the \ with /.
