我在Android Studio中运行虚拟机。问题是它从未挂载SD卡。 在设置中,我尝试过使用由Studio管理的(100MB)以及自己创建的SD卡:
$ ./mksdcard -l sdCard 100M sdcard.img
这个文件在我的家目录里,带有读写权限。
这是我的配置:
avd.ini.encoding=UTF-8
AvdId=DEVICEC_API_17
PlayStore.enabled=false
abi.type=x86
avd.ini.displayname=DEVICEC API 17
disk.dataPartition.size=800M
hw.accelerometer=no
hw.audioInput=yes
hw.battery=yes
hw.camera.back=emulated
hw.camera.front=emulated
hw.cpu.arch=x86
hw.cpu.ncore=4
hw.dPad=no
hw.device.manufacturer=User
hw.device.name=DEVICEC
hw.gps=no
hw.gpu.enabled=yes
hw.gpu.mode=auto
hw.initialOrientation=landscape
hw.keyboard=yes
hw.lcd.density=160
hw.mainKeys=no
hw.ramSize=1536
hw.sdCard=yes
hw.sensors.orientation=no
hw.sensors.proximity=no
hw.trackBall=no
image.sysdir.1=system-images/android-17/google_apis/x86/
runtime.network.latency=none
runtime.network.speed=full
sdcard.path=/home/user/sdcard.img
showDeviceFrame=no
skin.dynamic=yes
skin.name=800x600
skin.path=_no_skin
skin.path.backup=_no_skin
tag.display=Google APIs
tag.id=google_apis
vm.heapSize=48
正如您所看到的,hw.sdCard
被设置为 YES
。
说实话,我不知道在 Logcat 中该看什么。筛选 MOUNT 后,我看到了这个:
08-14 17:45:55.544 1495-1508/system_process I/SystemServer: Mount Service

08-14 17:45:55.554 1495-1533/system_process W/MountService: getSecureContainerList() called when storage not mounted
我也尝试在命令行中运行这个:
$ ./emulator -avd CASIO_API_17 -sdcard /home/mariano/sdcard.img
但我没有看到任何错误。SD卡只是无法挂载。
