错误日志里边列出了问题并且已经给出了解决方案 - 增加Java虚拟机的-Xmx<size>,即设置一个较大的堆内存上限

  • 修改Jack的配置文件prebuilts/sdk/tools/jack-admin
1
JACK_SERVER_COMMAND="java -XX:MaxJavaStackTraceDepth=-1 -Djava.io.tmpdir=$TMPDIR $JACK_SERVER_VM_ARGUMENTS -cp $LAUNCHER_JAR $LAUNCHER_NAME"

修改内存:-Xmx4096m

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

git clone https://github.com/anbox/anbox-modules.git

在anbox-modules安装完成后,需要对系统进行reboot,否则无法生成/dev/binder节点

1
sudo modprobe binder_linux num_devices=9

多容器编译生成binder节点,/dev/binder[0-9]
