Android模拟器sdcard推送错误:只读文件系统

I am developing under Android 1.6 (Android SDK 2.1). I create a avd by using avd manager in Eclipse. When I launch this avd, I found that the /sdcard directory's permisson is "d---------". So I can't push file to the sdcard.

我正在开发Android 1.6 (Android SDK 2.1)。我在Eclipse中使用avd管理器创建avd。当我启动avd时，我发现/sdcard目录的permisson是“d---------”。所以我不能把文件推到sdcard。

Does anyone know how to solve this problem?

有人知道如何解决这个问题吗?

Once you started the Emulator from one shell, login to another shell & type

一旦您从一个shell启动模拟器，登录到另一个shell & type

adb shell

You should see # prompt displayed, this is your device(emulator) shell. Now , type following command at adb shell.

您应该会看到# prompt显示，这是您的设备(模拟器)shell。现在，在adb shell中输入以下命令。

mount -o remount rw /sdcard

This will now remount /sdcard with rw(read-write) permission & now you can push your files into /sdcard by using following command from your host shell.

这将使用rw(读写)权限重新加载/sdcard，现在您可以使用来自主机shell的以下命令将文件推入/sdcard。

`adb push filename.mp3 /sdcard,`

where filename.mp3 could be any file that you want to push into Android Emulator.

文件名的地方。mp3可以是任何你想要进入Android模拟器的文件。

Hope this helps :)

希望这有助于:)

#3

Ensure two things in the AVD manager utility for the emulator:

确保仿真器的AVD manager实用程序中有两件事:

SD Card size is mentioned e.g. 512.

SD卡尺寸如512。
From the Hardware tag, press New and select "SD Card Support" from the drop down menu.

从硬件标签，按新的和选择“SD卡支持”从下拉菜单。

Now, start the emulator. SD Card shall now support writing as well.

现在,启动模拟器。SD卡也应该支持书写。

Android studio version 0.8.9 and above has a bug creating AVDs.

Android studio 0.8.9及以上版本有创建AVDs的错误。

See Issue 78434.

看到发行78434。

Workaround

解决方案

go to your ADV folder in .android folder and find your AVD config.ini
在.android文件夹中找到你的文件夹，找到你的AVD config.ini文件。
open it with a text editor that can handle unix newlines. (Notepad will run the lines together since they don't have CR-LFs.)
使用可以处理unix换行的文本编辑器打开它。(记事本将一起运行这些行，因为它们没有CR-LFs。)
change hw.sdCard=no to hw.sdCard=yes
改变hw。sdCard = no hw.sdCard = yes

this should work for everyone in new builds

这应该适用于所有的新构建版本。

#5

Maybe it sounds stupid but it worked for me when I had the same problem: delete the created avd and create one again through AVD Manager with a sd card of, for example, 512MB.

也许这听起来很愚蠢，但当我遇到同样的问题时，它对我起了作用:删除已创建的avd，然后通过带有sd卡(例如512MB)的avd Manager再次创建一个avd。

Check that both have the correct permissions and if not, try to change them with chmod.

检查两者是否具有正确的权限，如果没有，请尝试使用chmod更改它们。

And if everything still fails, repeat the process but creating both avd and sd card manually via terminal:

如果仍然失败，重复这个过程，但是通过终端手工创建avd和sd卡:

android create avd -n my_avd -t 7
mksdcard -l e 512M mysdcard.img
emulator -avd my_avd -sdcard mysdcard.img

Hope that helps!

希望会有帮助!

#6

I think the problem here is that you forgot to set SD card size

我认为这里的问题是你忘记设置SD卡的大小

Follow these steps to make it work:

遵循以下步骤使它工作:

step1: close running emulator
步骤1:关闭运行模拟器
step2: open Android Virtual Device Manager(eclipse menu bar)
step2:打开Android虚拟设备管理器(eclipse菜单栏)
step3: choose your emulator -> Edit -> then set SD card size
步骤3:选择模拟器->编辑->，然后设置SD卡大小

This works well in my emulator!

这在我的模拟器中工作得很好!

#7

Make sure that you had given a value which is greater than zero for SD Card size in the Create AVD Window for that particular emulator.

确保在创建AVD窗口中为特定的仿真器指定的值大于0。

#8

mount -o remount, rw /sdcard

安装-o重新安装，rw /sdcard

this is the correct way to remount your sdcard using your emulator.

这是使用模拟器重新挂载sdcard的正确方式。

#9

I increased the virtual memory of sdcard up to 512 MB for the emulator and that was enough

我增加了sdcard的虚拟内存到512mb的模拟器，这就足够了。

#10

i tried @user2002993 great help but it one place it need to be a little edit so i edited and here what worked for me on android studio , emulator android 5 . go to your adb folder right click on blank arena and select "opne command window here " or if you installed adb by adb-installer open cmd and type these commands ( for not misunderstand i made command BOLD )

我尝试了@user2002993，很好的帮助，但是有一个地方它需要做一点编辑，所以我进行了编辑，这里是android studio，模拟器android 5。进入你的adb文件夹右键点击空白的竞技场，选择“opne命令窗口”或者如果你通过adb-installer安装了adb，打开cmd并输入这些命令(为了不理解错误，我将命令加粗)

yeah double exit needed .. now your prompt of adb shell is gone . put a file in to your adb folder and give this command and see if it got fixed

是的，需要双重出口。现在你对adb shell的提示已经没有了。将一个文件放到adb文件夹中，并给出这个命令，看看它是否得到了修复

adb push "your file name like : 1.jpg" /sdcard/

adb推送“您的文件名:1.jpg”/sdcard/

或

adb push "your file name like : 1.jpg" /storage/sdcard/

adb推送“您的文件名:1.jpg”/存储/sdcard/

now in cmd it shoudl show you transfer time instead of creepy read-only thing :)

I guess, you didn't insert memory size at the time of creating avd. you can do that by editing the avd. Android模拟器sdcard推送错误:只读文件系统

我猜，在创建avd时，您没有插入内存大小。您可以通过编辑avd来实现这一点。

Alternate way: Dismount the drive (from settings/storage) and re-mount the sdcard also fixes the problem. (verify by moving a file from internal storage to sdcard) In any case, this simple method saved my butt this time :)

另一种方法:从设置/存储中卸载驱动器，重新安装sdcard也可以修复问题。(通过将文件从内部存储移动到sdcard进行验证)在任何情况下，这个简单的方法都挽救了我的屁股:)
