在eclipse中编译android project,提示如标题的错误。
其原因有可能是eclipse heap overflow
解决办法:修改eclipse.ini中的Xms和Xmx
-startup
plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.1.R36x_v20100810
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms256m
-Xmx768m
注意值不能改太大,不然在launch eclipse的时候会出现“Failed to create Java Virtual Machine”

Conversion to Dalvik format failed: Unable to execute dex: null
out of memory error…An internal error occurred during: “Build Project”.

This is the DEX Error,I find the solutions by Google, one way is to modify the eclipse.ini, you can increase the memory allocated in eclipse.ini to this: -Xms128m -Xmx512m or something higher, but this didn’t work for me. After modify the eclipse.ini, I cannot start the eclipse. By StackOverflow, I find a solution:
eclipse.ini file must have -vm on first line and path on second line. don’t try to put everything into one line!
-vm
C:\Program Files\Java\jdk1.6.0_07\bin\javaw.exe
After add the -vm and the path in my eclipse.ini, I can start my Eclipse and the problem has been resolved.
Another way to solve the ” Conversion to Dalvik format failed: Unable to execute dex: null” problem is using the user library, the concrete steps are as follows :
