Material is cool

Be careful with some Samsung devices Proguard to the rescue!!! 

Tint doesn’t work on custom views!! 

com.android.support:recyclerview-v7 Bye Bye List view! Extends from RecyclerAdapter ViewHolder by default Layout manager 

com.android.support:recyclerview-v7 Change your dividers for ItemDecoration 

com.android.support:recyclerview-v7 Change your headers and footers for ItemTypes. 

com.android.support:recyclerview-v7 OnItemClick doesn’t exist any more, delegate click functionality to view holders 

com.android.support:recyclerview-v7 Add animations with ItemAnimator, it’s easy and it’s cool. 

com.android.support:cardview-v7 

com.android.support:palette-v7 Only in compat Check null Problems with some images 

Toolbar vs ActionBar ToolBar is a viewGroup setSupportActionBar(); Extends from ActionBarActivity Deactivate ActionBar via Theme 

VectorDrawable vs ‘Font as icon’ You can use icon fonts for reduce the number of assets on you app. Keep performance!!! please!! 

Transitions ActivityOptionsCompat options = ActivityOptionsCompat.
 makeSceneTransitionAnimation((Activity) context, pairs);
