Google is ending support for the Android Market app on Android 2.1 Eclair and older devices on June 30, 2017. When this change happens, users on these devices will no longer be able to access, or install other apps from, the Android Market. The Android Market was replaced by Google Play in 2012.
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.
There are less than 0.1 percent devices that run Android 2.1 or older and hence we have not seen Eclair in the monthly Google Android distribution numbers.
