在尝试编译Android N时遇到了两个问题：一是警告生成，二是Jack Server的Java堆内存不足导致的错误。解决方案包括修改prebuilts/sdk/tools/jack-admin文件中的-Xmx参数为4096m，并在jack-admin的start-server命令中增加-Xmx4096m选项以增大Java堆内存。

AndroidN编译需要用到java 1.8以上版本．

第一次出错：

解决办法：

　1.在文件/prebuilts/sdk/tools/jack-admin中修正-Xmx参数（－Xmx:4096m）.

　　JACK_SERVER_VM_ARGUMENTS="${JACK_SERVER_VM_ARGUMENTS:=-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx:4096m}"
2.jack-admin中的start-server语句，直接在里面增加：

在start_server的case 下,

start-server)

..............

JACK_SERVER_COMMAND="java -XX:MaxJavaStackTraceDepth=-1 -Djava.io.tmpdir=$TMPDIR $JACK_SERVER_VM_ARGUMENTS -Xmx4096m -cp $LAUNCHER_JAR $LAUNCHER_NAME"
