Errors with eclipse & ADT Version

Question

I have been working in eclipse on my android app.

I have opened the IDE today and got this message:

I tried to update the eclipse (Help ==> updates)

but not updates were found.

Then i have clicked on the SDK-manager and updated the SDK as requested.

I have restarted my IDE and yet I get these errors:

update

I did what @Daan suggested

but then I got:

Answer 1

This worked for me:

Go to Help -> Install new software -> fill in this URL

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

download all Developer Tools and NDK Plugins, restart and it should work again.

UPDATE AFTER UPDATE MAIN QUESTION

Found a simulair question about the error you got after u tried the above:

Answer:

Delete android-support-v4.jar from library and project. Then go in /extras/android/support/samples/Support4Demos/ and copy android-support-v4.jar and paste in libs folder of both.

Source:

Found 2 versions of android-support-v4.jar in the dependency list appcompat in android

Answer 2

This question is answered before in :

Error Message : This Android SDK requires Android Developer Toolkit version 22.6.1 or above

However, this is the fix

The problem is that the default update site in Android ADT is

http://dl-ssl.google.com/android/eclipse/

but this site don't update correctly

And the solution is add a new Install site with protocol https

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

Click in Help->Install New Software->Add

And use this site to update ADT
