更改swap分区之后，仍然报oom。

修改build/soong/java/config/config.go
pctx.StaticVariable(“JavacHeapSize”, “2048M”)
-> pctx.StaticVariable(“JavacHeapSize”, “1024M”)

修改build/soong/java/config/makevars.go
ctx.Strict(“DX_COMMAND”, “ ${D8Cmd} -JXms16M -JXmx2048M") -> ctx.Strict("DX_COMMAND", "$ {D8Cmd} -JXms16M -JXmx1024M”)

修改 build/soong/java/droiddoc.go
在增加Flag("-J-Xmx3112m").设置metalava的堆大小
就是我们经常过不了的这条frameworks/base/api-stubs-docs-non-updatable

cmd.BuiltTool(ctx, "metalava").
 		Flag(config.JavacVmFlags).
+		Flag("-J-Xmx3112m").
 		FlagWithArg("-encoding ", "UTF-8").
 		FlagWithArg("-source ", javaVersion.String()).

实测，只需要修改build/soong/java/droiddoc.go一处便可以

android@C3478:~/project/aosp-11-2/build/soong$ git status -v
位于分支 dev
要提交的变更：
  （使用 "git restore --staged <文件>..." 以取消暂存）
	修改：     java/droiddoc.go
