On June 30, 2017, Google will be ending support for the Android Market app on
Android 2.1 Eclair and older devices. When this change happens, users on these
devices will no longer be able to access, or install other apps from, the
Android Market. The change will happen without a notification on the device, due
to technical restrictions in the original Android Market app.
It has been 7 years since Android 2.1 Eclair launched. Most app developers are
no longer supporting these Android versions in their apps given these devices
now account for only a small number of installs.
We will still be supporting later versions of Android Market for as long as
feasible. Google Play, the replacement for
Android Market, is available on Android 2.2 and above.
