解决Android 源码编译错误的问题

如下所示：

Building with Jack: out/target/common/obj/JAVA_LIBRARIES/framework_intermediates/with-local/classes.dex
FAILED: /bin/bash out/target/common/obj/JAVA_LIBRARIES/framework_intermediates/with-local/classes.dex.rsp
Out of memory error (version 1.2-a26 'Carnac' (291201 fcd657165d2fd6dcf1bf4c3002c9c8f75383e815 by android-jack-team@google.com)).
GC overhead limit exceeded.
Try increasing heap size with java option '-Xmx<size>'.
Warning: This may have produced partial or corrupted output.
ninja: build stopped: subcommand failed.

在文件/prebuilts/sdk/tools/jack-admin中修正-Xmx参数。

1、修改变量JACK_SERVER_VM_ARGUMENTS，添加参数 -Xmx2048M

JACK_SERVER_VM_ARGUMENTS="${JACK_SERVER_VM_ARGUMENTS:=-Dfile.encoding=UTF-8 -XX:+TieredCompilation -mx2048M}"

2、进一步修正重启参数（该步骤可以省略）

找到jack-admin中的start-server语句，直接在里面增加：

start-server)

isServerRunning

RUNNING=$?

if [ "$RUNNING" = 0 ]; then

echo "Server is already running"

else

echo "before to start-server,JACK_SERVER_VM_ARGUMENTS=" $JACK_SERVER_VM_ARGUMENTS

JACK_SERVER_COMMAND="java -Djava.io.tmpdir=$TMPDIR $JACK_SERVER_VM_ARGUMENTS-Xmx2048M -cp $LAUNCHER_JAR $LAUNCHER_NAME"

echo "Launching Jack server" $JACK_SERVER_COMMAND

(

补充知识：编译android 7.0 出现Try increasing heap size with java option '-Xmx'错误解决方案

出现这个错误是由于电脑内存不足，在命令行分别执行以下三条语句，然后继续编译

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
