编译android遇到java虚拟机堆内存不够的问题 java.lang.OutOfMemoryError: GC overhead limit exceeded 解决方法

ubuntu 12.04 server(64位) 编译android遇到java虚拟机堆内存不够的问题UNEXPECTED TOP-LEVEL ERROR:java.lang.OutOfMemoryError: GC overhead limit exceeded    at com.android.dx.dex.code.OutputFinisher.findExpandedOpcodeForInsn(OutputFinisher.java:525)    at com.android.dx.dex.code.OutputFinisher.calculateReservedCount(OutputFinisher.java:466)    at com.android.dx.dex.code.OutputFinisher.reserveRegisters(OutputFinisher.java:402)    at com.android.dx.dex.code.OutputFinisher.finishProcessingAndGetList(OutputFinisher.java:358)    at com.android.dx.dex.code.DalvCode.finishProcessingIfNecessary(DalvCode.java:108)    at com.android.dx.dex.code.DalvCode.getInsns(DalvCode.java:185)    at com.android.dx.dex.file.CodeItem.place0(CodeItem.java:223)    at com.android.dx.dex.file.OffsettedItem.place(OffsettedItem.java:242)    at com.android.dx.dex.file.MixedItemSection.placeItems(MixedItemSection.java:312)    at com.android.dx.dex.file.DexFile.toDex0(DexFile.java:543)    at com.android.dx.dex.file.DexFile.toDex(DexFile.java:216)    at com.android.dx.command.dexer.Main.writeDex(Main.java:574)    at com.android.dx.command.dexer.Main.run(Main.java:218)    at com.android.dx.command.dexer.Main.main(Main.java:174)    at com.android.dx.command.Main.main(Main.java:95)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。

编译android4.1.1遇到的问题：

问题1：

Exception in thread "main" java.lang.OutOfMemoryError: Java heap spaceat java.util.Vector.<init>(Vector.java:111)at java.util.Vector.<init>(Vector.java:124)at org.antlr.analysis.DFA.createTransitionTableEntryForState(DFA.java:551)at org.antlr.analysis.DFA.createStateTables(DFA.java:440)at org.antlr.codegen.CodeGenerator.genLookaheadDecision(CodeGenerator.java:645)at org.antlr.grammar.v3.CodeGenTreeWalker.block(CodeGenTreeWalker.java:2876)at org.antlr.grammar.v3.CodeGenTreeWalker.rule(CodeGenTreeWalker.java:2382)at org.antlr.grammar.v3.CodeGenTreeWalker.rules(CodeGenTreeWalker.java:1537)at org.antlr.grammar.v3.CodeGenTreeWalker.grammarSpec(CodeGenTreeWalker.java:1441)at org.antlr.grammar.v3.CodeGenTreeWalker.grammar_(CodeGenTreeWalker.java:461)at org.antlr.codegen.CodeGenerator.genRecognizer(CodeGenerator.java:421)at org.antlr.Tool.generateRecognizer(Tool.java:655)at org.antlr.Tool.process(Tool.java:468)at org.antlr.Tool.main(Tool.java:93)make: *** [out/host/common/obj/JAVA_LIBRARIES/smali_intermediates/smaliLexer.java] Error 1make: *** Waiting for unfinished jobs....

这个问题同样是提示java虚拟机内存的问题，解决的思路是一样的，但解决这个问题需要修改的是external/smali/smali/Android.mk

这个mk文件，将Android.mk文件中的$(GEN): PRIVATE_CUSTOM_TOOL = java -jar $(ANTLR_JAR) -fo $(dir $@) $<.这行，修改为

$(GEN): PRIVATE_CUSTOM_TOOL = java -Xmx512m  -jar $(ANTLR_JAR) -fo $(dir $@) $<.

问题2：

make: *** 正在删除文件“out/host/common/obj/JAVA_LIBRARIES/temp_layoutlib_intermediates/javalib.jar”

这个问题也是java虚拟机内存的问题，解决的方法是修改frameworks/base/tool/layoutlib/Android.mk

将文件中的 $(hide) java -jar $(built_layoutlib_create_jar) \ 这行修改为如下：

$(hide) java  -Xmx512M  -jar $(built_layoutlib_create_jar) \
