A CoordinatorLayout layout, with a Google Map that collapse itself. A TabLayout (inside the CollapsingToolbarLayout) provides navigation for the ViewPager, that sits just below the AppBarLayout. The FloatingActionButton is used to go to the next page in the ViewPager.
<android.support.design.widget.CoordinatorLayout
android:id="@+id/main_content"

xmlns:app="http://schemas.android.com/apk/res-auto"

<android.support.design.widget.AppBarLayout

Multiple Python installations on OS X

Previous versions used homebrew to install the various versions. As suggested in the comments, it's better to use pyenv instead. If you are looking for the previous version of this document, see the revision history.

$ brew update
$ brew install pyenv
$ pyenv install 3.5.0
$ pyenv install 3.4.3
$ pyenv install 3.3.6
$ pyenv install 3.2.6
$ pyenv install 2.7.10

$ pyenv install 2.6.9
