Updated Android ADT, now errors occur

Question

I just updated my android adt to version 17 and now I can not start my Android projects. When I try to update, it gives me an error:

The Android SDK requires the Android Developer Toolkit version 17.0.0 or higher. The current version is 16.0.1.v201112150204-238534. Update ADT to the latest version.

I tried updating it, but it shows me this

Cannot complete the request. See the error log for details. Android DDMS will be ignored because it is already installed, and updates are not permitted. Android Development Tools will be ignored because it is already installed, and updates are not permitted. Android Hierarchy Viewer will be ignored because it is already installed, and updates are not permitted. Android Traceview will be ignored because it is already installed, and updates are not permitted. 

Is there a way to fix this or can I lower ADT to fix this problem.

Answer 1

Get the latest ADT by going to the rescue, install the software and enter https://dl-ssl.google.com/android/eclipse/

if it doesn’t allow you to select "available sites"

Answer 2

I had almost the same problem when trying to update Android ADT tools on my Windows 7 machine. I turned off Eclipse starting, as the administrator solved the problem for me and I was able to update normally.

Answer 3

• Moved my Android folder to Root.
• open the SDK manager outside the eclipse by viewing it.
• Rotate your antivirus protection
• Disable zonealarm
• Unistall SDK Tools and SDK platform tools.
• close the manager and launch the eclipse.
• (Inside Eclipse) Help → Install new software → ADD "name =" ADT PLUGIN ", location" https://dl-ssl.google.com/android/eclipse/ "---> OK -----> Check the developer tools window. I believe I had a damaged installation of 20, so the eclipse knew that it was there, but did not know that it was incomplete. I hope this will save someone, which took me 3 hours to understand this is.

Answer 4

Delete all folders / jars in \ eclipse \ plugins and \ eclipse \ features. Try installing the Android ADT tools again. If you still have the same error as the Android search word in the eclipse folder (installation). Remove everything except platform.xml. open the .xml platform and find the android xml tags and delete everything. Try installing again. This issue is resolved below.

Android DDMS will be ignored because it is already installed and updates are not allowed.
Android development tools will be ignored because they are already installed and updates are not allowed.
The Android Hierarchy Viewer will be ignored as it is already installed and updates are not allowed.
Android Traceview will be ignored as it is already installed and updates are not allowed.

Answer 5

The step I tried: Run the SDK manager and try updating ADT.
