Android ics 编译时GC overhead limit exceeded错误解决方法

出错的log信息如下

UNEXPECTED TOP-LEVEL ERROR:java.lang.OutOfMemoryError: GC overhead limit exceededat com.android.dx.ssa.SsaBasicBlock.<init>(SsaBasicBlock.java:125)at com.android.dx.ssa.SsaMethod.makeNewGotoBlock(SsaMethod.java:240)at com.android.dx.ssa.SsaBasicBlock.insertNewSuccessor(SsaBasicBlock.java:454)at com.android.dx.ssa.SsaConverter.edgeSplitMoveExceptionsAndResults(SsaConverter.java:210)at com.android.dx.ssa.SsaConverter.edgeSplit(SsaConverter.java:136)at com.android.dx.ssa.SsaConverter.convertToSsaMethod(SsaConverter.java:48)at com.android.dx.ssa.Optimizer.optimize(Optimizer.java:99)at com.android.dx.ssa.Optimizer.optimize(Optimizer.java:73)at com.android.dx.dex.cf.CfTranslator.processMethods(CfTranslator.java:273)at com.android.dx.dex.cf.CfTranslator.translate0(CfTranslator.java:134)at com.android.dx.dex.cf.CfTranslator.translate(CfTranslator.java:87)at com.android.dx.command.dexer.Main.processClass(Main.java:483)at com.android.dx.command.dexer.Main.processFileBytes(Main.java:455)at com.android.dx.command.dexer.Main.access$400(Main.java:67)at com.android.dx.command.dexer.Main$1.processFileBytes(Main.java:394)at com.android.dx.cf.direct.ClassPathOpener.processArchive(ClassPathOpener.java:245)at com.android.dx.cf.direct.ClassPathOpener.processOne(ClassPathOpener.java:131)at com.android.dx.cf.direct.ClassPathOpener.process(ClassPathOpener.java:109)at com.android.dx.command.dexer.Main.processOne(Main.java:418)at com.android.dx.command.dexer.Main.processAllFiles(Main.java:329)at com.android.dx.command.dexer.Main.run(Main.java:206)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：

更改编译配置文件build/core/definitions.mk中的缓存参数：

define transform-classes.jar-to-dex
@echo "target Dex: $(PRIVATE_MODULE)"
@mkdir -p $(dir $@)
$(hide) $(DX) \
    $(if $(findstring windows,$(HOST_OS)),,-JXms16M -JXmx1536M) \
    --dex --output=$@ \
    $(incremental_dex) \
    $(if $(NO_OPTIMIZE_DX), \
        --no-optimize) \
    $(if $(GENERATE_DEX_DEBUG), \
   --debug --verbose \
   --dump-to=$(@:.dex=.lst) \
   --dump-width=1000) \
    $(PRIVATE_DX_FLAGS) \
    $<
endef

将红色标注部分的参数值更改为较大的值：-JXms1024M -JXmx1536M    （我的机器是8G内存），然后再次make，错误应该就不会再出现了。

不过参数的数值请根据自己的机器适当的改大，数值太大编译时会很卡。

Good luck to you~
