android sdk manager exe does not work

I installed the Eclipse IDE version 4.4.0.

I got errors such that when I looked on how to fix them I found I needed to download and install the "SDK manager". So I downloaded that and SDK Manager is now installed on my machine (Win 7) and is one of programs listed in start button list all programs.

When I dbl click on sdk manager, nothihg seems to happen, so I go directl;y to the command line

at C:\Users\Stephen\AppData\Local\Android\android-sdk

where I see the "SDK Manager.exe" file so I invoke it
and when I do so it appears to do nothing, as if it started to execute, encountered an error and ended.

No error message of any kind seen on the screen.


As I said, I have eclipse Java IDE installed already but it tells me

"The Android sdk requires the new build tools component to be installed

Please open SDK manager and install android sdk build-tools"

so I dont know how to get past this point since I cannot get sdk manager.exe to run.

Thanks

searching on web I found suggestion to do:


tools\android at command line, which produces:

Download whole ADT bundle from here:

http://developer.android.com/sdk/index.html (Download Eclipse ADT)

it will install as a separate Eclipse install, and to be honset it's better to keep it that way.

you will probably be instructed to install all necessary plugins and desired Android version compatibility packages, but from this install you shoould get youe IDE running in no time.

If you want to struggle and install Android SDK tools to your existing Eclipse, try to proceed along GET THE SDK FOR AN EXISTING IDE option on above linked page.

To develop Andriod apps you need all the tools, not only the SDK Manager. SDK Manager is just a part responsible for obtaining handle to tools installation.

List of all bundles you can find under VIEW ALL DOWNLOADS AND SIZES, pick appropriate pack for your system and DO MIND the bitness of your system (32/64bit)

I believe this is functionally what I have done previously.  (I have gone through the entire process several times)


I am hoping to be able totake 2 steps fwd. w/o taking any back due to all the time I put in thus far, not to mention I have done it more than once....



I will hopefully see this thread out where I can solve problem by going fwd only....

I am thinking it is something along the lines of not having a path variable set correctly but am hoping someone will be able to give me specifics

Did you really install the whole bundle ?

This should pput all necessary stuff in the place they should be.

Try to install everything in a path not containing spaces or any spec chars.

Also, make sure you grab appropriate bitness (32/64 bit) as this has strong influence on Java and how the classes are seen.
