Sounds a bit familiar with my problem  aapt not found under the right path  I needed to clean all open projects to get it working again

Judging from what you ve posted  and assuming it s not a typo  Eclipse is looking in C  s platform-tools     If that s the case  then you should check Eclipse s Window Preferences Android option for the SDK Location  Maybe yours is set to  C  s   You can t edit it to be a value such as that without causing an error  but maybe it s got corrupted somehow

I had a similar problem with adb exe and Eclipse last time I updated ADT plugin  The solution was to run Eclipse as administrator and reinstall ADT

I had exactly the same problem with you  And after two days wondering why this occurs to me  I finally got through this by moving the adb exe from the unreliable software list of the COMODO anti-virus to its reliable software list  At that time  I had tried at least 5 kinds of measures to make the adb work  including all above

Reinstall everything    no way  just add the path to SDK tools and platform tools in your classpath from Environment Variables  Then restart Eclipse    other way go to Devices - gt  Reset adb  or simply open the task manager and kill the adb exe process

The problem might be with your firewall or antivirus    Disable all network connection  Disable firewall Disable Antivirus   Make sure they all disabled    Run your script in Eclipse   If it works  then 2 and 3 might be the culprit  For me  it was comodo firewall   I  created a filter for Adb exe

For me the following worked    Kill adb exe from Task Manager Restart Eclipse as administrator For my app  the target was Google APIs level 10   I went to Window-  AVD Manager and the entry for  Google APIs level 10  had a broken instead of a green tick - so I just clicked the entry and clicked the  repair  button and problem was fixed    It was probably only 3 above

It s also possible to get this error if you are running the test project using JUnit instead of Android JUnit  Naturally  the solution is just to change how you run it
