When I try to open up the SDK Manager in eclipse it says opening shortly, but never opens. I\'ve tried to open the exe file but it displays an error message saying:
In My case, While I installed visual studio 2015, The SDK files were missed and I am getting an error window shown below.
So I manually downloaded the tools from the following URL.
tools_r24.0.2-windows
Then extract the zip file and copy the tools folder in the following location.
C:\Program Files (x86)\Android\android-sdk
It worked for me.
