I'm newly configured Android Eclipse neon in Ubuntu. When I try to open the eclipse it throws error As "Failed to get the required ADT version number from the SDK. The Android Development Toolkit may not work properly"
I have tried many references but i am unable to solve the issue as given in references to reinstall ADT plugin.Which i have tried many times and does not solve the issue.
Finally i got an answer.
You first restart your eclipse and check it.
If again throws same error please try this steps:
1. Download latest SDK tools package package from google.Download here end of the page.
2. Extract the tools package.
3. Replace Exract folder(ToolsPackage) to ANDROID_SDK_DIRECTORY/tools folder.
4. Now fixed the issue. works fine for me.
