make: *** [out/target/common/obj/JAVA_LIBRARIES/framework_intermediates/noproguard.classes-with-local.dex] error 3
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)),,-JXms16M -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。
