How to change android sdk directory in a project


After this problem with eclipse update : getDefaultProguardFile no longer returns valid path using build SDK tools 23 I had to reinstall Eclipse with a new path.

I changed my $PATH for sdk bin ,
but now when I do ‘ionic build android’ I understand that old path is used and saved in many files in the project ionic,
so I replaced all paths occurrences in the project.

Still not work in files where sdk.dir is used to contain the path.
Even if sdk.dir contains the good path in …/platforms/android/

Question is :
What can I do to build without changing the path of the new eclipse install

Thanks for help !
