我试图在ubuntu 15.10中构建android源代码,但是我收到了一个错误.现在我希望你的帮助来构建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

然后我运行“$java -Xmx2048m”命令,我得到一些代码：
smile@smile:~/Android$java -Xmx2048m
Usage: java [-options] class [args...]
(to execute a class)
or java [-options] -jar jarfile [args...]
(to execute a jar file)
where options include:
-d32 use a 32-bit data model if available
-d64 use a 64-bit data model if available
-server to select the "server" VM
-zero to select the "zero" VM
-jamvm to select the "jamvm" VM
-avian to select the "avian" VM
-dcevm to select the "dcevm" VM
The default VM is server.
-cp <class search path of directories and zip/jar files>
-classpath <class search path of directories and zip/jar files>
A : separated list of directories, JAR archives,
and ZIP archives to search for class files.
-D<name>=<value>
set a system property
-verbose:[class|gc|jni]
enable verbose output
-version print product version and exit
-version:<value>
require the specified version to run
-showversion print product version and continue
-jre-restrict-search | -no-jre-restrict-search

-? -help print this help message
-X print help on non-standard options
-ea[:<packagename>...|:<classname>]
-enableassertions[:<packagename>...|:<classname>]

-disableassertions[:<packagename>...|:<classname>]
disable assertions with specified granularity
-esa | -enablesystemassertions
enable system assertions
-dsa | -disablesystemassertions
disable system assertions

load native agent library <libname>, e.g. -agentlib:hprof
see also, -agentlib:jdwp=help and -agentlib:hprof=help
-agentpath:<pathname>[=<options>]
load native agent library by full pathname
-javaagent:<jarpath>[=<options>]
load Java programming language agent, see java.lang.instrument
-splash:<imagepath>

谁能帮我如何增加堆大小？
你的帮助会非常适合我
提前致谢.
smile@smile:~/Android$java -version
java version "1.7.0_91"
OpenJDK Runtime Environment (IcedTea 2.6.3) (7u91-2.6.3-0ubuntu0.15.10.1)
OpenJDK 64-Bit Server VM (build 24.91-b01, mixed mode)
解决方法:
我遇到了同样的问题.
问题是运行插孔的虚拟机没有足够的内存.
您可以尝试编辑jvm命令：
JACK_VM_COMMAND=${JACK_VM_COMMAND:="java -Xmx4096m"}
或减少并行插孔编号的数量
SERVER_NB_COMPILE=2
在?/ .jack文件中.
有关详细信息,请阅读jack documentation.
编辑：
更改.jack文件对我不起作用.
在深入挖掘后,我发现jack服务器是以/ 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
