我无法编辑android模拟器的主机文件 [英] I can't edit android emulator's host file

问题描述

我尝试编辑android模拟器的主机文件.请按以下步骤操作:

I try to edit android emulator's host file.I follow steps:

step1
adb root
step2
adb remount
step3
adb pull /system/etc/hosts .

然后添加新行以获取客户主机信息，然后推送主机文件，出现一些错误:

then I add new line for customer host information,then I push hosts file,I get some errors:

   step4
   adb push hosts /system/etc/hosts

错误信息:

adb: error: failed to copy 'hosts' to '/system/etc/hosts': couldn't create file: Read-only file system

环境信息:

   osx ei capitan  
   android emulator: android 7.1.1  
   android studio: 2.2.2  

推荐答案

我只是遇到了同样的问题并使它起作用.

I just ran into the same problem and made it work.

运行模拟器:

emulator -avd< EMULATORNAME>-partition-size 512-可写系统

我相信 -writable-system 参数是为我修复的东西.

I believe that -writable-system param is the thing that fixed it for me.

在另一个终端/cmd提示符下:

adb根

adb -s emulator-5554重新安装

adb -s emulator-5554 pull/system/etc/hosts主机

现在，发挥您的魔力(将IP添加到主机文件)

Now, work your magic (add the IP to host file)

adb -s emulator-5554推送主机/system/etc/hosts

其他信息:

• emulator-5554是设备名称，您可以使用 adb设备
查找自己的设备名称
• 模拟器程序位于android-sdk/tools内部
• adb程序位于android-sdk/platform-tools

评论的重要更新:

在运行 adb root 之前，请检查从steven到此帖子有关运行 adb重新启动的评论.这对于能够从AVD管理器启动仿真器可能很重要.

Please check the comment from steven to this post about running adb reboot before running adb root. This might be important to being able to start the emulator from AVD manager.

队长建议在推送主机文件后运行 adb重新启动，以避免出现黑屏错误.

Captain suggests to run adb reboot after pushing the host file to avoid blackscreen error.

调试愉快:)
