Old-style 'onionservicesonly' is deprecated but still accepted.
The configuration option will be upgraded upon the first GUI settings update.

+PyBitmessage(Android)
+
+This sample aims to be as close to a real world example of a mobile. It has a more refined design and also provides a practical example of how a mobile app would interact and communicate with its addresses.
+
+Steps for trying out this sample:
+
+Compile and install the mobile app onto your mobile device or emulator.
+
+
+Getting Started
+
+This sample uses the kivy as Kivy is an open source, cross-platform Python framework for the development of applications that make use of innovative, multi-touch user interfaces. The aim is to allow for quick and easy interaction design and rapid prototyping whilst making your code reusable and deployable.
+
+Kivy is written in Python and Cython, supports various input devices and has an extensive widget library. With the same codebase, you can target Windows, OS X, Linux, Android and iOS. All Kivy widgets are built with multitouch support. 
+
+Kivy in support take Buildozer which is a tool that automates the entire build process. It downloads and sets up all the prerequisite for python-for-android, including the android SDK and NDK, then builds an apk that can be automatically pushed to the device.
+
+Buildozer currently works only in Linux, and is an alpha release, but it already works well and can significantly simplify the apk build.
+
+To build this project, use the "Buildozer android release deploy run" command or use.
+Buildozer ue=sed for creating application packages easily.The goal is to have one "buildozer.spec" file in your app directory, describing your application requirements and settings such as title, icon, included modules etc. Buildozer will use that spec to create a package for Android, iOS, Windows, OSX and/or Linux.
+
+Installing Requirements
+
+You can create a package for android using the python-for-android project as with using the Buildozer tool to automate the entire process. You can also see Packaging your application for the Kivy Launcher to run kivy programs without compiling them.
+
+You can get buildozer at https://github.com/kivy/buildozer or you can directly install using pip install buildozer
+
+This will install buildozer in your system. Afterwards, navigate to your project directory and run:
+
+buildozer init
+
+This creates a buildozer.spec file controlling your build configuration. You should edit it appropriately with your app name etc. You can set variables to control most or all of the parameters passed to python-for-android.
+
+Install buildozer’s dependencies.
+
+Finally, plug in your android device and run:
+
+buildozer android debug deploy run >> To build, push and automatically run the apk on your device. Here we used debug as tested in debug mode for now.
+
+Packaging your application for the Kivy Launcher

+Bottom Sheets
+=============
+
+`Material Design spec Bottom Sheets page <http://www.google.com/design/spec/components/bottom-sheets.html>`_
+
+In this module there's the :class:`MDBottomSheet` class which will let you implement your own Material Design Bottom Sheets, and there are two classes called :class:`MDListBottomSheet` and :class:`MDGridBottomSheet` implementing the ones mentioned in the spec.
+
+Examples
+--------
+
+.. note::
+
+    These widgets are designed to be called from Python code only.
+
+For :class:`MDListBottomSheet`:
+
+.. code-block:: python
+
+    bs = MDListBottomSheet()
+    bs.add_item("Here's an item with text only", lambda x: x)
+    bs.add_item("Here's an item with an icon", lambda x: x, icon='md-cast')
+    bs.add_item("Here's another!", lambda x: x, icon='md-nfc')
+    bs.open()
+
+For :class:`MDListBottomSheet`:
+
+.. code-block:: python
+
+    bs = MDGridBottomSheet()
+    bs.add_item("Facebook", lambda x: x, icon_src='./assets/facebook-box.png')
+    bs.add_item("YouTube", lambda x: x, icon_src='./assets/youtube-play.png')
+    bs.add_item("Twitter", lambda x: x, icon_src='./assets/twitter.png')
+    bs.add_item("Da Cloud", lambda x: x, icon_src='./assets/cloud-upload.png')
+    bs.add_item("Camera", lambda x: x, icon_src='./assets/camera.png')

+Lists
+=====
+
+`Material Design spec, Lists page <https://www.google.com/design/spec/components/lists.html>`_
+
+`Material Design spec, Lists: Controls page <https://www.google.com/design/spec/components/lists-controls.html>`_
+
+The class :class:`MDList` in combination with a ListItem like
+:class:`OneLineListItem` will create a list that expands as items are added to
+it, working nicely with Kivy's :class:`~kivy.uix.scrollview.ScrollView`.
+
+
+Simple examples
+---------------
+
+Kv Lang:
+
+.. code-block:: python
+
+    ScrollView:
+        do_scroll_x: False  # Important for MD compliance
+        MDList:
+            OneLineListItem:
+                text: "Single-line item"
+            TwoLineListItem:
+                text: "Two-line item"
+                secondary_text: "Secondary text here"
+            ThreeLineListItem:
+                text: "Three-line item"
+                secondary_text: "This is a multi-line label where you can fit more text than usual"
+
+
+Python:
+
+.. code-block:: python
+
+    # Sets up ScrollView with MDList, as normally used in Android:
+    sv = ScrollView()
+    ml = MDList()
+    sv.add_widget(ml)
+
+    contacts = ["Paula", "John", "Kate", "Vlad"]
+    for c in contacts:
+        ml.add_widget(
+            OneLineListItem(
+                text=c
+            )
+        )
+
+Advanced usage
+--------------
+
+Due to the variety in sizes and controls in the MD spec, this module suffers
+from a certain level of complexity to keep the widgets compliant, flexible
+and performant.
+
+For this KivyMD provides ListItems that try to cover the most common usecases,
+when those are insufficient, there's a base class called :class:`ListItem`
+which you can use to create your own ListItems. This documentation will only
+cover the provided ones, for custom implementations please refer to this
+module's source code.
+
+Text only ListItems

+These are the simplest ones. The :attr:`~ListItem.text` attribute changes the
+text in the most prominent line, while :attr:`~ListItem.secondary_text`
+changes the second and third line.
+
+If there are only two lines, :attr:`~ListItem.secondary_text` will shorten
+the text to fit in case it is too long; if a third line is available, it will
+instead wrap the text to make use of it.

+ListItems with widget containers
+--------------------------------

+- :class:`~OneLineAvatarListItem`
+- :class:`~TwoLineAvatarListItem`
+- :class:`~ThreeLineAvatarListItem`
+- :class:`~OneLineIconListItem`
+- :class:`~TwoLineIconListItem`
+- :class:`~ThreeLineIconListItem`
+- :class:`~OneLineAvatarIconListItem`
+- :class:`~TwoLineAvatarIconListItem`
+- :class:`~ThreeLineAvatarIconListItem`
+
+These widgets will take other widgets that inherit from :class:`~ILeftBody`,
+:class:`ILeftBodyTouch`, :class:`~IRightBody` or :class:`~IRightBodyTouch` and
+put them in their corresponding container.
+
+As the name implies, :class:`~ILeftBody` and :class:`~IRightBody` will signal
+that the widget goes into the left or right container, respectively.
+
+:class:`~ILeftBodyTouch` and :class:`~IRightBodyTouch` do the same thing,
+except these widgets will also receive touch events that occur within their
+surfaces.
+
+Python example:
+
+.. code-block:: python
+
+    class ContactPhoto(ILeftBody, AsyncImage):
+        pass
+
+    class MessageButton(IRightBodyTouch, MDIconButton):
+        phone_number = StringProperty()
+
+        def on_release(self):
+            # sample code:
+            Dialer.send_sms(phone_number, "Hey! What's up?")
+            pass
+
+    # Sets up ScrollView with MDList, as normally used in Android:
+    sv = ScrollView()
+    ml = MDList()
+    sv.add_widget(ml)
+
+    contacts = [
+        ["Annie", "555-24235", "http://myphotos.com/annie.png"],
+        ["Bob", "555-15423", "http://myphotos.com/bob.png"],
+        ["Claire", "555-66098", "http://myphotos.com/claire.png"]
+    ]

+        item = TwoLineAvatarIconListItem(
+            text=c[0],
+            secondary_text=c[1]
+        )
+        item.add_widget(ContactPhoto(source=c[2]))
+        item.add_widget(MessageButton(phone_number=c[1])

+CircularLayout
+==============
+
+CircularLayout is a special layout that places widgets around a circle.
+
+See the widget's documentation and the example for more information.
+
+![Screenshot](screenshot.png)
+
+size_hint
+---------
+
+size_hint_x is used as an angle-quota hint (widget with higher
+size_hint_x will be farther from each other, and viceversa), while
+size_hint_y is used as a widget size hint (widgets with a higher size
+hint will be bigger).size_hint_x cannot be None.
+
+Widgets are all squares, unless you set size_hint_y to None (in that
+case you'll be able to specify your own size), and their size is the
+difference between the outer and the inner circle's radii. To make the
+widgets bigger you can just decrease inner_radius_hint.
