Android SDK installation doesn't find JDK

Question

I'm trying to install the Android SDK on my Windows 7 x64 System. jdk-6u23-windows-x64.exe is installed, but the Android SDK setup refuses to proceed because it doesn't find the JDK installation.

Is this a known issue? And is there a solution?

Answer 1

I tried several posted solutions and then it took a system reboot before it started working, which may have been because I had just installed the JDK. Here are all the things I had going on - not sure which ones were essential:

• 64-bit JDK installed.
• JAVA_HOME defined using forward slashes (/) instead of backslashes ().
• JDK 'bin' directory listed at beginning of PATH.
• System reboot.

Answer 2

Try downloading and installing the zipped version rather than the .exe installer.

Answer 3

I had the same problem and solved it by installing the x86 version of the JDK (on Windows XP x64).

Answer 4

Non of these solutions worked for me. I fixed it by temporarily changing the filename of C:\Windows\System32\java.exe to java_.exe

Answer 5

I had the same problem, tried all the solutions but nothing worked. The problem is with Windows 7 installed is 64 bit and all the software that you are installing should be 32 bit. Android SDK itself is 32 bit and it identifies only 32 bit JDK. So install following software.

1. JDK (32 bit)
2. Android SDK (while installing SDK, make sure install it in directory other than "C:\Program Files (x86)", more probably in other drive or in the directory where Eclipse is extracted)
3. Eclipse (32 bit) and finally ADT.

I tried it and all works fine.

Answer 6

Adding JAVA_HOME environment variable (under System Variables) did the trick for me. Clicking "Back" and "Next" buttons didn't work.

Windows 7 Professional x64, JDK 1.7.0_04 (64 bit, I don't have x86 version installed)

I think that installer tries to find JDK in specific (1.6?) version and if it can't find it, checks JAVA_HOME which was not set in my case. I have another computer (the same system but with JDK 1.6 x64) and it worked without JAVA_HOME variable.

You don't have to install 32 bit version of JDK :)
