Eclipse: please check aapt is present at "..\sdk\build-tools\23.0.0_rc1\aapt.exe"

@Josecash's answer worked like a charm. Here's the solution from that link in english.

It turns out that now the binaries in the build-tools / 23.0.0_rc1 / folder are in a subfolder called bin, so when eclipse will not find them in its new route, the fastest solution is to create a direct link to the binary the folder you are looking eclipse.

In linux:

$ cd / path / to / sdk /build-tools/23.0.0_rc1/
$ ln -s bin/aapt

In Windows: Let the path to the SDK to build-tools \ 23.0.0_rc1 \ bin \ folder Once there click the right mouse button on AAPT -. create direct link, then copy the link to the upper build-tools \ 23.0 folder. 0_rc1 \ and change the name aapt.exe

Then just restart eclipse.
