4.1 安卓模拟器检测不到sd卡 [英] 4.1 android emulator not detecting sd card

问题描述

我曾经使用带有 sd 卡的 4.1 kitkat x86 android 模拟器进行测试.将 Android Studio 升级到 2.3 后，我无法再访问 android 中提供的 SD 卡，因此我无法进行测试.谷歌对此没有答案，我也没有在模拟器或 adb 日志中看到任何线索.avd 已重新创建，(我删除了旧的 avd 文件夹以防止 goop 弄脏东西).它根本不再起作用.

I used to use a 4.1 kitkat x86 android emulator with an sd card for testing. After upgrading Android Studio to 2.3, i'm no longer able to access the supplied sdcard in android making testing impossible for me. Google hasn't had answers for this and i also fail to see any clues in the emulator or adb logs. The avd has been recreated new, (i deleted the old avd folder to prevent goop from fouling things up). It simply doesn't work anymore.

这是在 Kubuntu 14.04 amd64 上启动模拟器时的输出

Here's the output when starting the emulator on Kubuntu 14.04 amd64

任何线索都将不胜感激，因为这已成为真正的表演障碍.

Any clues would be much appreciated as this has become a real show stopper.

推荐答案

我猜额头流血的主任现在可以回答他自己的问题了.

I guess chief bleeding forehead can answer his own question now.

降级模拟器确实可以解决问题.不确定这是否是答案，但在有人提供替代方案之前必须这样做.

Downgrading the emulator does fix the problem. Not sure if it's the answer, but it'll have to do until someone supplies an alternative.

我没有发现旧版本的模拟器，因为它已从 sdk-tools 包中移出.由于我已经将 sdk-tools 降级到 25.2.5，我只需要删除模拟器包.自从 Android-Studio 更新以来，我一直像这样手动启动模拟器:

I found no older versions of the emulator because it was moved out of the sdk-tools package. Since i already downgraded sdk-tools to 25.2.5, i simply needed to delete the emulator package. Since the Android-Studio update i've been manually starting the emulator like this:

LD_LIBRARY_PATH=/usr/local/android-sdk/tools/lib64/qt/lib:/usr/local/android-sdk/tools/lib64/libstdc++:/usr/local/android-sdk/tools/lib64:/usr/local/android-studio/bin: /usr/local/android-sdk/tools/qemu/linux-x86_64/qemu-system-i386 -netdelay none -netspeed full -avd and4.1

and4.1 是我的奇巧图片.

LD_LIBRARY_PATH 防止以下错误

The LD_LIBRARY_PATH prevents the following error

/usr/local/android-sdk/tools/qemu/linux-x86_64/qemu-system-i386:加载共享库时出错:libQt5Widgets.so.5:无法打开共享对象文件:没有这样的文件或目录

/usr/local/android-sdk/tools/qemu/linux-x86_64/qemu-system-i386: error while loading shared libraries: libQt5Widgets.so.5: cannot open shared object file: No such file or directory

添加这个以防其他一些可怜的人浪费时间.

Adding this in case some other poor soul wastes time on this.

顺便说一句.降级前的路径是:

BTW. Before the downgrade, the path was:

/usr/local/android-sdk/emulator/qemu/linux-x86_64/qemu-system-i386

代替:

/usr/local/android-sdk/tools/qemu/linux-x86_64/qemu-system-i386
