解决方法：

方法一：

用java命令指定java虚拟机堆的大小来把需要编译的东西先编译出来，可能需要几分钟。

java -Xms3550M -Xmx3550M -jar /home/test/4.0/out/host/linux-x86/framework/dx.jar –dex –output=out/target/common/obj/JAVA_LIBRARIES/framework_intermediates/noproguard.classes-with-local.dex –core-library out/target/common/obj/JAVA_LIBRARIES/framework_intermediates/noproguard.classes.jar

运行完这个后。再重新make就好了，因为这个包已经被make出来了，所以重新make的时候不会再去编译它

这个方法只能是make出错后在执行上述命令，然后在接着执行make命令

方法二：

修改definitions.mk文件此文件位于build/core/目录下

修改变量：transform-classes.jar-to-dex中的 -JXms16M -JXmx1024M 值

代码中的变量定义:

define transform-classes.jar-to-dex

@echo “target Dex: $(PRIVATE_MODULE)”

@mkdir -p $(dir $@)

$(hide) $(DX) \

$(if $(findstring windows,$(HOST_OS)), ,-J Xms16M -JXmx1024M ) \

–dex –output=$@ \

$(if $(NO_OPTIMIZE_DX), \

–no-optimize) \

$(if $(GENERATE_DEX_DEBUG), \

–debug –verbose \

–dump-to=$(@:.dex=.lst) \

–dump-width=1000) \

$(PRIVATE_DX_FLAGS) \

endef

将-JXms16M -JXmx1024M 修改成适当的值

我的机器是内存是32G的，我将-JXms16M -JXmx1024M修改为-JXms1024M -JXmx2048M

具体值的大小要根据具体机器的内存而定，内存太少设置的值大一样会出现问题。
