The right way to avoid weird issues.... [Noob Proof sorry in advance]
It actually works perfect if you just do the following:
1. Right Click My Computer -> Properties
2. On the left pane, Find and Click "Advanced system settings"
3. Under the "Advanced" Tab Find and Click "Environment Variables..."
4. In the box for "User variables for [your name here; e.g. David]" there will be a button that says "New..." Click it.
5. Now you have a box in front of you with two fields:
1. Variable name: entering path here is really safer and can help to avoid clogging up the environment namespaces (cluttering your ram/registry)
2. Variable value: directory containing the adb.exe you want to use**; i.e.
Code:
C:\Android\sdk\platform-tools
**to find this with ease search for "adb.exe" or look for it in "...sdk\platform-tools\" or "sdk\tools".
**This is a version dependent thing for the Android SDK which folder its in.
6. Click OK on all the dialogs and exit the windows we opened here.
7. Hit the windows key + R and type cmd.exe; hit Enter
8. Type adb into the newly opened cmd window. hit Enter
9. If adb runs all is well. Your DONE. If not continue to step 10.
--If it work stop here!--
10. At this point we are going to select our entry from step 5. (in Environment variables...)and delete it. Otherwise windows has two pointers to our adb.exe.
11. Navigate in the "System variables" box and scroll down until you see Path in the Variable Column. Select it and Click "Edit..."
12. Click inside "Variable value:" go to the very end of this and drop a ";" no spaces. Enter the value from Step 5.2
13. Click OK/Apply on all dialogs and reboot your PC.
14. Repeat steps 7-9 and if all is well your done. If not you may need to redownload the AndroidSDK from here:
http://developer.android.com/sdk/index.html then repeat this guide.
The reason for first trying to do this under "User" as opposed to "System" is if you need to track your changes to Path in case anything goes wrong as it can be a daunting task to go through the System version (its really full of stuff that needs to be there XD )
But don't take my word for it: My path
Code:
%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static
and my Windows is brand new Store-bought not OEM. It tends get get bigger the more stuff windows needs to globally keep track of that doesn't live in C:\Windows\
Hope this helped!
