Android 6.0
"Marshmallow"[3] is a version of the Android mobile operating system. First unveiled in May 2015
at Google I/O under the codename
"Android 'M'", it was officially released in October 2015.[4]
Marshmallow primarily
focuses on improving the overall user experience ofLollipop,[5] introducing a new
permissions architecture, new APIs for contextualassistants (a feature notably
leveraged by "Google
Now On Tap"—a new capability of the Google Search app), a new
power management system that reduces background activity when a device is not
being physically handled, native support for fingerprint recognition and USB Type-C connectors, the ability
to migrate data to a microSD card and use it as
primary storage, as well as other internal changes.

The developer preview
build, codenamed Android "M", was unveiled and released at Google I/O on May 28, 2015, for the Nexus 5 and Nexus 6 phones, Nexus 9tablet, and Nexus Player set-top box, under the
build number MPZ44Q.[5][6] The third developer
preview under build number MPA44G was released on August 17, 2015,[7] later updated to MPA44I,
and brought fixes related to Android for Workprofiles.[8]"Marshmallow"
was officially announced as the release's name the same day.[3]
On September 29, 2015,
Google unveiled launch devices for Marshmallow: the LG Electronics-produced Nexus 5X, theHuawei-produced Nexus 6P, and the
in-house Pixel C tablet.[9][10] Android 6.0 updates and
factory images for Nexus 5, 6, 7 (2013), 9, and
Player were released on October 5, 2015,[11] with over-the-air updates following shortly
after. Older Nexus devices, such as the Nexus 4, Nexus 7 (2012) and Nexus 10 did not receive an
official update. On October 14, 2015, LG announced that it planned to release
Marshmallow for its flagship LG G4 in Poland the following
week, marking the first third-party device to receive an update to Marshmallow.[12]
A new "Assist"
API allows information from a currently-opened app, including text and a
screenshot of the current screen, to be sent to a designated "assistant" application for analysis and
processing. This system is used by the Google Search app feature "Google Now on Tap", which
allows users to perform searches within the context of information currently
being displayed by holding the "Home" button or using a voice
command. The search generates on-screen cards overlaid onto the app, which
display information, suggestions, and actions related to the content.[13] "Direct Share"
allows Share menus to display combinations of contacts and an associated app to
be displayed, as opposed to selecting an app and then choosing a target within
the app itself..[13]
A newly-inserted SD card
or other secondary storage media can be designated as either
"Portable" or "Secondary" storage. "Portable"
maintains the default behavior of previous Android versions, treating the media
as a secondary storage device for storage of user files, and the storage media
can be removed or replaced without repercussions.[13] When designated as
"Internal" storage, the storage media is reformatted with an
encrypted ext4 file system, and is
"adopted" by the operating system as the primary storage partition.
Existing data (including applications and "private" data folders) are
migrated to the external storage, and normal operation of the device becomes
dependent on the presence of the media. Apps and operating system functions
will not function properly if the adopted storage device is removed. If the
user loses access to the storage media, the adopted storage can be
"forgotten", which makes the data permanently inaccessible.[13]
Android Marshmallow
introduces a redesigned application permission model: there are now only eight
permission categories, and applications are no longer automatically granted all
of their specified permissions at installation time. An opt-in system is now used,
in which users are prompted to grant or deny individual permissions (such as
the ability to access the camera or microphone) to an application when they are
needed for the first time. Applications remember the grants, which can be
revoked by the user at any time.[14] The new permission model
will be used only by applications compiled for Marshmallow using its software development kit (SDK), and all other
applications will continue to use the previous permission model.[5][15]
Marshmallow introduces a
new power management scheme known as
"Doze"; when running on battery power, a device will enter a
low-power state if it is inactive and not being physically handled. In this
state, network connectivity and background processing is restricted, and only
"high-priority" notifications are processed.[13]
Android Marshmallow
provides native support for fingerprint recognition on supported devices via
a standard API, allowing third-party applications to
implement fingerprint-based authentication. Fingerprints can be used for
unlocking devices and authenticating Play Store and Android Pay purchases. Android
Marshmallow supports USB Type-C,
including the ability to instruct devices to charge another device over USB.
Marshmallow also introduces "verified links" that can be configured
to open directly in their specified application without further user prompts.[5][15] User data for apps
targeting Marshmallow can be automatically backed up to Google Drive over Wi-Fi. Each
application receives up to 25 MB of storage, which is separate from a
user's Google Drive storage allotment.[13]
As of Marshmallow, the
Android Compatibility Definition Document contains new security mandates for
devices, dictating that those that are capable of accessing encrypted data at a
certain minimum speed must enable Secure boot and device encryption by
default.[16] These conditions comprise
part of a specification that must be met in order to be certified for the
operating system,[16] and be able to license Google Mobile Services software.[17] The requirement for
mandatory device encryption was originally intended to take effect on Lollipop,
but was delayed due to performance issues.[16]
