Android SDK中的Find_java.exe找不到Java

Question

I've definitely got JDK 1.6.0 installed in C:\\Program Files\\Java\\jdk1.6.0_35 , but it never seems to be able to find it when I try to open the SDK Manager. In task manager, find_java.exe shows up until I stop it (will run for hours).

Are there some environment variables I have to set for this to work?

Answer 1

May be you are forgetting the PATH environmental variable. To check this use,

In Unix/Linux systems,

echo $PATH
echo $JAVA_HOME

In Windows systems,

echo %PATH%
echo %JAVA_HOME%

If both the tests showed you empty lines, then you may need to set them again.

To set them do this. First try reinstalling java with UAC turned off. If it failed, do this at the cmd

SetX PATH %PATH%;<path_to_jdk/jre>\bin\
SetX JAVA_HOME <path_to_jdk/jre>

Hope it helps and thinking you are using windows.

As you are using Windows system, use following way to set your JAVA_HOME and CLASSPATH Environment variables.

Windows XP

• Select Start, select Control Panel. double click System, and select the Advanced tab.
• Click Environment Variables. In the section System Variables, find the PATH environment variable and select it. Click Edit. If the PATH environment variable does not exist, click New.
• In the Edit System Variable (or New System Variable) window, specify the value of the PATH environment variable. Click OK. Close all remaining windows by clicking OK.

Windows Vista:

• From the desktop, right click the My Computer icon.
• Choose Properties from the context menu.
• Click the Advanced tab (Advanced system settings link in Vista).
• Click Environment Variables. In the section System Variables, find the PATH environment variable and select it. Click Edit. If the PATH environment variable does not exist, click New.
• In the Edit System Variable (or New System Variable) window, specify the value of the PATH environment variable. Click OK. Close all remaining windows by clicking OK.

   PATH=$PATH:/opt/jdk1.6.0_21/bin export PATH JAVA_HOME=/opt/jdk1.6.0_21 export JAVA_HOME NDK_HOME=/opt/android-ndk-r8 export NDK_HOME
