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
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.
