gradle - Failed to resolve: com.android.support:appcompat-v7:23.0.3 -

i continuously facing problem: failed resolve: com.android.support:appcompat-v7:23.0.3

although have updated packages going sdk manager

but still facing same problem. when creating new project same problem persist. kindly guide.

the no such version of support libraries.

here can find list.

i suggest using newest: 25.0.0.

build tools version , support libraries version different thing.

buildtoolsversion field in build.gradle configuration file in android closure.

support libraries declared in dependencies closure.
