One of your problems is Long File Names in Windows. A number of the Android tools cannot handle them. I filed a bug report on them years ago, but I can't find it at the moment. I also seem to recall something about it in the INSTALL or README.

So you should install the tools in a location without spaces. Use something like C:\Android\ or C:\Android-SDK\.

@Steve and @MeatPopsicle already mentioned spaces in the pathames, but it can't be overstated.

Actually a black cmd window appears and disappears a milliseconds.
... Even I set path for ANDROID_SWT

Out of curiosity, where did ANDROID_SWT come from?

I know Android does use ANDROID_HOME, ANDROID_SDK_ROOT and ANDROID_NDK_ROOT, and the last two should both be set because the tools use them internally. Here's the reference on ANDROID_SDK_ROOT and ANDROID_NDK_ROOT: Recommended NDK Directory?.

So you should set the three environmental variables (after ensuring the installation directory does not contain spaces):

• ANDROID_HOME
• ANDROID_SDK_ROOT
• ANDROID_NDK_ROOT

ANDROID_HOME is set to the directory where the hidden directory .android is.

ANDROID_SDK_ROOT is set to the directory where the SDK is installed, like C:\Android-SDK\.

ANDROID_NDK_ROOT is set to the directory where the NDK is installed, like C:\Android-NDK\. If its not installed, then don't set it.

Once you have ANDROID_SDK_ROOT set, you can put %ANDROID_SDK_ROOT%\tools and %ANDROID_SDK_ROOT%\platform-tools on PATH. Then, you can drop into a command line and issue something like this (and it just works):

adb list
