API Level: {@sdkPlatformApiLevel}
- -- Android 5.1 - (LOLLIPOP_MR1) - is an update to the Lollipop release that offers new features for users and app developers. - This document provides an introduction to the most notable new APIs. -
- -- For a high-level look at the new platform features, see the Android Lollipop highlights. -
- - -
- To start building apps for Android 5.1, use the
- SDK Manager to download the Android 5.1 SDK
- Platform and System Images. Then set your app development project to use a
- {@code targetSdkVersion}
- of "{@sdkPlatformApiLevel}". Install your app on an Android {@sdkPlatformVersion}
- system image, test it, then publish the updated app with this change.
-
- You can use Android {@sdkPlatformVersion} APIs while also supporting older versions by adding - conditions to your code that check for the system API level before executing APIs not supported - by your {@code - minSdkVersion}. To learn more about maintaining backward compatibility, read Supporting Different Platform - Versions. -
- -- For more information about how API levels work, read What is API Level? -
- -- Android 5.1 adds support for using more than one cellular carrier SIM card at a time. This - feature lets users activate and use additional SIMs on devices that have two or more SIM card - slots. -
- -- You can access information about the currently active SIM through the {@link - android.telephony.SubscriptionManager} class, including whether or not the device is considered - to be roaming on the current network. This information is useful for developers who want to - throttle their apps' data access down or off for device users who are sensitive to data access - charges. Your app can be alerted to changes in a device's current network connection by - requesting the {@link android.Manifest.permission#READ_PHONE_STATE} permission and setting {@link - android.telephony.SubscriptionManager.OnSubscriptionsChangedListener} on the {@link - android.telephony.SubscriptionManager} object. -
- - -- The {@code org.apache.http} classes and the {@link android.net.http.AndroidHttpClient} class - have been deprecated in Android 5.1. These classes are no longer being maintained and you should - migrate any app code using these APIs to the {@link java.net.URLConnection} classes as soon as - possible. -
- - -- Android 5.1 provides support for telecommunication service providers to create apps that can - perform carrier provisioning tasks on an Android device. These APIs provide a secure and flexible - way for carrier-developed apps to perform these tasks and be distributed through Google Play. Apps - that use these functions must be signed by a certificate that matches the certificate in the - device's Universal Integrated Circuit Card (UICC). -
- -- The carrier service APIs have been added to the {@link android.telephony.TelephonyManager} class, - the {@link android.telephony.SmsManager} class, and the new {@link - android.service.carrier.CarrierMessagingService} class. Apps can check for access to these APIs - by calling the {@link android.telephony.TelephonyManager#hasCarrierPrivileges} method. Apps that - call these APIs without access receive a {@link java.lang.SecurityException}. -
