Yesterday evening I upgrade to ADT-21
and restarted eclipse. Then eclipse said that you need to update android tool to version 21. I downloaded window_installer21
and install it in the same location where my previous window_installer was installed. So it overwrite the file. Then I restarted eclipse and suddenly all project stop working. Eclipse always open with the error.
SecurityException: Unable to find field for dex.jar
And when i try to launch a project it stops with the below error
Unknown error: Unable to build: the file dx.jar was not loaded from the SDK folder!
SDK Manager is also not opening.
I have tried:
This, this.and this one also.
Nothing seems to work.
A popup appears warning you to update to the latest sdk and opens the appropriate tool. Tried this (several times - restarting each time) with no effect.
Instead the answer was ..
In eclispe, find the location of your android sdk (Window->Preferences->Android and the SDK location is at the top of the page).
Close down eclispe.
Find the sdk on the disk - and run the standalone SDK Manager.exe (It appears to fail when first opened - but wait a second or two for the gui to appear). Note - this is the same gui that was previously opened by eclipse!
Take all the updates as recommended. A dialog box appears indicating that the management tool itself has been updated and should be restarted.
Restart the tool - take any more updates recommended and close.
Start eclipse - the problem has gone away!
