android - 4.1 android 模拟器没有检测到 sd 卡

Question

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 sdcard，这让我无法进行测试。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)。它根本不再起作用了。

这是在 Kubuntu 14.04 amd64 上启动模拟器时的输出

Answer 1

我想首席流血的额头现在可以回答他自己的问题了。

降级模拟器确实解决了这个问题。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。

我没有找到旧版本的模拟器，因为它已从 sdk-tools 包中移出。因为我已经将 sdk-tools 降级到 25.2.5，所以我只需要删除模拟器包。自 Android-Studio 更新以来，我一直在像这样手动启动模拟器:

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 kitkat 图片。

LD_LIBRARY_PATH 防止以下错误

/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

添加这个以防其他可怜的人浪费时间在这上面。

顺便说一句。降级前路径为:

/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
