This section is in a list format that may be better presented using prose. (March 2012) |
Google announced the Android Market on 28 August 2008, and made it
available to users on 22 October 2008. They introduced support for paid
applications on 13 February 2009 for US and UK developers,[54][55] with additional support for 29 countries on 30 September 2010.
In December 2010, Google added content filtering to Android Market
and reduced the purchase refund window from 24–48 hours to 15 minutes.[56]
In February 2011, Google introduced a web client that provides access
to Android Market via PC. Applications requested through the Android
Market web page are downloaded and installed on a registered Android
device.[57]
In May 2011, Google added new application lists to Android Market,
including "Top Grossing" applications, "Top Developers", "Trending"
applications, and "Editors Recommendations". Google's Eric Chu said the
goal of this change was to expose users to as many applications as
possible.[58]
In July 2011, Google introduced a redesigned interface with a focus
on featured content, more search filters, and (in the US) book sales and
movie rentals.[59]
In September 2011, the Motorola Xoom tablet received an update that brought the redesigned Android Market to an Android 3.x Honeycomb based device.[60]
In November 2011, Google added a music store to the Android Market.[61]
In March 2012, the maximum allowed size of an application's APK file
was also increased from 50MB to allow two additional files for a maximum
of 50MB for the APK and two additional files of 2GB each, totalling
4146MB/4.05GB.[62]
On 6 March 2012, the Android Market was re-branded as Google Play.[63]
[edit] Device compatibility
The Google Play application is not open source.
Only Android devices that comply with Google's compatibility
requirements may install and access Google's closed-source Google Play
application, subject to entering into a free-of-charge[64] licensing agreement with Google.[65] In the past, these requirements had included 3G or 4G cellular data connectivity,[66] ruling out Android-powered devices comparable to Apple's iPod touch, but this requirement had been loosened by the 2011 release of the Samsung Galaxy Player.
Google Play applications are self-contained Android Package files.
Google Play does not install applications; it asks the device's
PackageManagerService to install them. The package manager becomes
visible if the user downloads an APK
file directly into their device. Applications are installed to the
phone's internal storage, and under certain conditions may be installed
to the device's external storage card.[67]
