编译 Android 源码遇到 Xmx 错误的快速处理方案

Try increasing heap size with java option '-Xmx<size>'.
Warning: This may have produced partial or corrupted output.
[ 60% 38768/63594] build out/target/common/obj/JAVA_LIBRARIES/amap_loc_intermediates/classes.jack
ninja: build stopped: subcommand failed.
make: *** [ninja_wrapper] Error 1

出现 Xmx 错误是由于电脑内存不足，一般在命令行执行以下三条语句再编译就行了。

export JACK_SERVER_VM_ARGUMENTS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx4g"
./prebuilts/sdk/tools/jack-admin kill-server
./prebuilts/sdk/tools/jack-admin start-server

以下内容是我工作环境的备忘，可以忽略。

~/.jack

# Server settings
SERVER=true
SERVER_PORT_SERVICE=8072
SERVER_PORT_ADMIN=8073
SERVER_COUNT=1
SERVER_NB_COMPILE=2
SERVER_TIMEOUT=120
SERVER_LOG=${SERVER_LOG:=$SERVER_DIR/jack-$SERVER_PORT_SERVICE.log}
JACK_VM_COMMAND=${JACK_VM_COMMAND:="java -Xmx4096m"}

~/.jack-settings

# Server settings

# Internal, do not touch

~/.bashrc

export JACK_SERVER_VM_ARGUMENTS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx4096m"

find jack

ps -ef| grep -i com.android.jack.launcher

restart jack

kill jack_process
your_out/host/linux-x86/bin/jack-admin start

Jack Server not report error after using jack 4.7beta (>_<)

1. kill your jack server
2. copy the old jack command to  your_out/host/linux-x86/bin/
