Following the official announcement of Android 5.1, and after giving us factory images for a few Nexus devices, Google has released the Android 5.1 SDK for developers. The Android 5.1 SDK brings the platform to API Level 22, which provides the API that supports multiple SIM cards and enhances enterprise features to better support the newly-announced Android for Work platform.
Also in the update is support for “Carrier Services”, which lets applications developed by carriers modify provisioning tasks such as altering IP addresses for different data connections and multiple other functions regarding the placement of phone calls.
Android 5.1 doesn’t carry with it too many new APIs, so most developers might have a hard time finding something that will revolutionize their apps. However, its always smart to have support for the latest version of Android, as 5.1 carries thousands of fixes that could be beneficial to you. For developers who’d like to begin using the new APIs, head to the source link below.
Google also adds that it will begin rolling out the Android 5.1 update to all current Nexus devices, including the Nexus Player. We’ve already seen 5.1 come to the Nexus 5, and according to a Sprint document, the Nexus 6 should be receiving it today as well.
