First eclipse boot will have two bullet box error, a about system-img about cant find ADT (probably meaning), but in the online related question and answer very little, so the post hope can help and I have the same problem of small partners.
First, it is recommended that you do not share a directory with studio, you can copy one out,
Careful classmates may find that the SDK is updated with multiple files, as well as missing a lot of files such as the key folders that need to solve this problem today tools
And this is the new tools folder.
This is the original SDK Tools folder.
Here the problem is obvious, the new SDK is missing a lot of eclipse required files, copied to their own SDK directory can be solved, and let's not forget if you have upgraded the ADT version of Eclipse, please note that modify Tools/lib/plugin.pro The version of the file. Finally, re-reference SDK, restart can be resolved, both DDMS and devices can be used normally.
