I get java code 13 error when i try to run eclipse

Question

I am new to this and wanted to try my hand at android app development. so i downloaded the SDK and ADT from https://developer.android.com. after this i realized i needed a Java thing so i downloaded jdk1.8.0_20 from the Java Site . my ecplise folder is in c:\Android\ ( "Android" being a folder I created for this purpose) the Java i installed is in C:\Program Files (x86)\Java . Also my system is running on a 64 bit windows 7 OS. Now when i run eclipse i get the following error.

Java was started but returned exit code=13
C:\ProgramData\Oracle\Java\javapath\javaw.exe

-jar C:\Android\eclipse\\plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar

now after all this i checked the eclipse.ini file and this is what it had

-startup plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
-
-launcher.library plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20120913-144807

-
-launcher.defaultAction openFile
-vmargs
-Dosgi.requiredJavaVersion=1.6
-XX:MaxPermSize=256m
-Xms512m
-Xmx1024m

So can someone please help me and tell me what to do.. or better still tell me what i need to download and install on my 64bit windows 7 system so I can start learning some android app development. your help will be much appreciated.

Answer 1

I had this problem happen overnight when I hadn't changed anything. I suspect that there was a auto-update of C:\ProgramData\Oracle\Java.

I solved this problem simply by renaming C:\ProgramData\Oracle\Java to C:\ProgramData\Oracle\JavaXXX so it isn't found and $JAVA_HOME is used instead.

I don't have time to look into this any further and will if my change breaks something else :(
