android – How can I update my ADT in Eclipse?

Posted by: admin March 11, 2020 Leave a comment


I have tried to update my Eclipse. Currently I have till 2.2 Android SDK in my Eclipse. Yesterday I have updated my Eclipse like this:

Eclipse -> window -> Android SDK Manager -> I have checked two check-boxes from list. Tools -> Android SDK Tools and Android SDK Platform Tools.

I have posted here some last lines of the message which I get from downloading and installing:

But after all this after I have closed Eclipse and again wanted to start, it throw the error:

This Android SDK requires Android Developer Toolkit version 20.0.0 or above. Current version is 16.0.0.v201203301601-306762. Please update ADT to the latest version.

In preferences I received this error:

This Android SDK requires Android Develop… Please update ADT to the latest version.

How to&Answers:

You have updated the android sdk but not updated the adt to match with it.

You can update the adt from here

You might need to update the software source for your adt update

Go to eclipse > help > Check for updates.

It should list the latest update of adt. If it is not working try the same *Go to eclipse > help > Install new software * but now please do the follwing:

It will list the updates available- which should ideally be adt 20.xx

Eclipse will restart and hopefully everything should work fine for you.


I had this problem. Since I already had the ADT address I could not follow the suggested fix. The reason why the update was not working in my case is that the ADT address was not checked in the list of “Available updates”.

1) Go to eclipse > help > Install new software

2) Click on “Available Software site”

3) Check that you have the ADT address

4) If not add it following the Murtuza Kabul’s steps

5) if yes check that the address is checked (checkbox on the left of the address)

I run the update after having launched Eclipse as administrator to be sure that it was not going to have problems accessing the system folders


I viewed the Eclipse ADT documentation and found out the way to get around this issue. I was able to Update My SDK Tool to 22.0.4 (Latest Version).

Solution is: First Update ADT to 22.0.4 and then Update SDK Tool to

The above link says,

ADT 22.0.4 is designed for use with SDK Tools r22.0.4. If you haven’t already installed SDK Tools r22.0.4 into your SDK, use the Android SDK Manager to do so

What I had to do was update my ADT to 22.0.4 (Latest Version) and then I was able to update SDK tool to 22.0.4. I thought only SDK Tool has been updated not ADT, so I was updating the SDK Tool with Older ADT Version (22.0.1).

How to Update your ADT to Latest Version

  1. In Eclipse go to Help

  2. Install New Software —> Add

  3. inside Add Repository write the Name: ADT (or whatever you want)

  4. Location: https://dl-ssl.google.com/android/eclipse/

  5. after loading you should get Developer Tools and NDK Plugins

  6. check both if you want to use the Native Developer Kit (NDK) in the future or check

  7. Developer Tool only

  8. click Next

  9. Finish


In my case opening ‘Help’ >> “Install New Software” had no entries for any URLs (previous url’s were not there) – so I Manually added ’em. And updated … and Voilaaaa !!
Above posts have been very helpful in resolving this issue for me.


Running as administrator then following other comments fixed the problem for me 🙂


Reason to that is with the new update, they changed the URL for the Android Developer Tools update site to require HTTPS. If you are updating ADT, make sure you use HTTPS in the URL for the Android Developer Tools update site.


I had the same problem where there’s no files under Generated Java files, BuildConfig and R.java were missing. The automatic build option is not generating.
In Eclipse under Project, uncheck Build Automatically. Then under Project select Build Project. You may need to fix the projec
