当我尝试打开Storage from 设置菜单在模拟器中，它（总是）崩溃并显示以下 logcat 输出
java.lang.NullPointerException at com.android.settings.deviceinfo.StorageVolumePreferenceCategory.updatePreferencesFromState(StorageVolumePreferenceCategory.java:238)
以下是我的 AVD 的详细信息：
Name: Mx
Path: /home/vvy/.android/avd/Mx.avd
Target: Android 4.2.2 (API level 17)
ABI: armeabi-v7a
Skin: 480x800
Sdcard: /home/vvy/Documents/ANDU/sdC.img

hw.dpad: no
avd.ini.encoding: ISO-8859-1
disk.dataPartition.size: 200M
hw.gpu.enabled: yes
hw.cpu.model: cortex-a8
hw.ramSize: 512
hw.sdCard: yes
hw.device.name: Nexus One
vm.heapSize: 32
请注意，我能够从 eclipse DDMS 角度将数据上传到 SDCard，并且 Stock GALLERY 应用程序能够显示通过 DDMS 角度推送的图像内容。
这是一个已知的问题 ？或者我做错了什么？

UPDATE
有人可以告诉我他们是否让库存存储应用程序在（模拟器）android 4.2.2 中工作
不过，存储应用程序在 android 2.3.7 图像（在模拟器上）上运行良好！而且我还没有找到解决办法
UPDATE
也不适用于 x86 图像。我在 LinuxMint13 和 Win7 上都尝试过。
