<style name="AppTheme" parent="BaseAppTheme"> <item name="android:windowContentTransitions">true</item> <item name="android:windowAllowEnterTransitionOverlap">true</item> <item name="android:windowAllowReturnTransitionOverlap">true</item> </style>
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); !

<style name="AppTheme" parent="BaseAppTheme"> <item name="android:windowContentTransitions">true</item> <item name="android:windowAllowEnterTransitionOverlap">true</item> <item name="android:windowAllowReturnTransitionOverlap">true</item> </style>
