As a work-around, you can define the environment variable android_sdk_home

Point to the directory containing your. Android directory. The emulator and SDK

Manager will pick it up properly.

Will look into this. There is likely a difference between the way the SDK manager and

Emulator pick up the user's directory when this variable is not defined.

Set android_sdk_home = E:
Start G: \ soft \ eclipse-java-indigo-win32 \ eclipse \ eclipse.exe

---- Q3 -----
The ADB tool has moved to platform-tools/

If you don't see this directory in your SDK,
Launch the SDK and AVD Manager (execute the android tool)
And install "android SDK

Platform-Tools"

Please also update your path environment variable
Include

Platform-tools/directory, so you can
Execute ADB from any location.

ADB uninstall com. example. Android. APIs

Note: Before run the command, pls run the AVD first
