Is there a way to mount Android .img to access the AVD (Android Virtual Device) contents?

You can just mount the device in Linux:

sudo mount -o loop ~/.android/avd/<myvirt>/sdcard.img <destdir>

android virtual disk mount avd

How about "adb shell"?

This will give you a root shell (on the emulator)..

android virtual disk mount avd

For MacOS X users:

$ hdiutil attach ~/.android/avd/Samsung_Nexus_S.avd/sdcard.img
