在 Ubuntu 15.10 上构建 android 源代码时增加堆大小

Question

我正在尝试在 ubuntu 15.10 中构建 android 源代码，但出现错误。现在我需要你的帮助来构建 android 源代码。

 including ./tools/external/fat32lib/Android.mk ...
Starting build with ninja
ninja: Entering directory `.'
[  0% 1/21542] Ensure Jack server is installed and started
Jack server already installed in "/home/smile/.jack-server"

然后我运行“$ java -Xmx2048m”命令，我得到一些行：

  smile@smile:~/Android$ java -Xmx2048m

谁能帮助我如何增加堆大小？

我将非常感谢你的帮助

Answer 1

我刚遇到同样的问题。

问题是运行 jack 的虚拟机没有足够的内存。

您可以尝试编辑 jvm 命令：

 JACK_VM_COMMAND=${JACK_VM_COMMAND:="java -Xmx4096m"}

或减少并行插孔编译的数量

SERVER_NB_COMPILE=2

在 ~/.jack 文件中。

您可以阅读 jack 文档 了解详细信息。

编辑：更改 .jack 文件对我不起作用。在深入研究之后，我发现 jack 服务器是使用 out/host/linux-x86/bin/jack-admin 脚本启动的，它的参数可以通过 JACK_SERVER_VM_ARGUMENTS 环境变量传递。

所以我的解决方案是在构建 aosp 之前设置它并重新启动 jack 服务器：

 export JACK_SERVER_VM_ARGUMENTS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx4096m"
out/host/linux-x86/bin/jack-admin kill-server
out/host/linux-x86/bin/jack-admin start-server
