I have downloaded the image of Froyo from the ADV manager, but when trying to emulate it, the following eror appears to me
Emulator: emulator: ERROR: This AVD's configuration is missing a kernel file! Please ensure the file "kernel-qemu" is in the same location as your system image.
Emulator: emulator: ERROR: ANDROID_SDK_ROOT is undefined
Emulator: Process finished with exit code 1
The image uses the ABI "armeabi" instead of "armeabi-v7a"
