New AudioRecord. Builder and AudioTrack. Builder classes to create digital audio capture and playback objects respectively, and configure audio source and sink properties to override the system defaults.

API hooks for associating audio and input devices. This is particularly useful if your app allows users to start a voice search from a game controller or remote control connected to Android TV.

The system invokes the new onSearchRequested callback when the user starts a search. To determine if the user's input device has a built-in microphone, retrieve the InputDevice object from that callback, then call the new hasMicrophone method. New getDevices method which lets you retrieve a list of all audio devices currently connected to the system. You can also register an AudioDeviceCallback object if you want the system to notify your app when an audio device connects or disconnects.

Video Features This release adds new capabilities to the video processing APIs, including: New MediaSync class which helps applications to synchronously render audio and video streams. The audio buffers are submitted in non-blocking fashion and are returned via a callback. It also supports dynamic playback rate.

If your app uses DRM sessions, you should handle this event and make sure not to use a reclaimed session. With this exception, the codec must be released, as it has moved to terminal state. New getMaxSupportedInstances interface to get a hint for the max number of the supported concurrent codec instances. New setPlaybackParams method to set the media playback rate for fast or slow motion playback.

It also stretches or speeds up the audio playback automatically in conjunction with the video. To get an empty buffer, follow this programming model: Call the dequeueInputImage method. Fill the data into the input buffer.

Send the buffer to the camera by calling the queueInputImage method. Disable or re-enable the status bar including quick settings, notifications, and the navigation swipe-up gesture that launches Google Now with the setStatusBarDisabled method. You can now provision devices through a Device Owner that fetches and installs apps without user interaction. This feature is useful for enabling one-touch provisioning of kiosks or other such devices without activating a Google account.

Silent enterprise certificate access: When an app calls choosePrivateKeyAlias , prior to the user being prompted to select a certificate, the Profile or Device Owner can now call the onChoosePrivateKeyAlias method to provide the alias silently to the requesting application.

This feature lets you grant managed apps access to certificates without user interaction. Auto-acceptance of system updates. By setting a system update policy with setSystemUpdatePolicy , a Device Owner can now auto-accept a system update, for instance in the case of a kiosk device, or postpone the update and prevent it being taken by the user for up to 30 days.

Furthermore, an administrator can set a daily time window in which an update must be taken, for example during the hours when a kiosk device is not in use. When a system update is available, the system checks if the device policy controller app has set a system update policy, and behaves accordingly. Profile Owners are automatically granted permission to query data on the profile they manage, while Device Owners get access to usage data of the managed primary user.

Runtime permission management: A Profile or Device Owner can set a permission policy for all runtime requests of all applications using setPermissionPolicy , to either prompt the user to grant the permission or automatically grant or deny the permission silently. For Profile Owner, the notifications are specific to whether the VPN is configured for a managed profile, a personal profile, or both.

For a Device Owner, the notifications are specific to whether the VPN is configured for the entire device. Work status notification: A status bar briefcase icon now appears whenever an app from the managed profile has an activity in the foreground.

Furthermore, if the device is unlocked directly to the activity of an app in the managed profile, a toast is displayed notifying the user that they are within the work profile.

When developing an application we require a min sdk version or API level for Android app development. Some cases the earlier app which you have developed was in older version and your current Android Studio sdk does not have that version and you are looking to get that version in your android studio then follow the below given steps:.

Step 2 : Click on Tools options in Android toolbar. Step 3 : Android studio will show you an pop up window. That is:. As each new version of Android is released, the framework API is updated to provide new or replacement functionality.

With few exceptions, API functionality from earlier Android versions is carried forward into newer Android versions without modifications. But what if you also want to run your app on earlier versions of Android? If you select a Minimum Android version that is lower than your Target Framework setting, some APIs may not be available to your app at runtime. However, your app can still run on an earlier device, but with reduced functionality. For each API that is not available on Android platforms corresponding to your Minimum Android version setting, your code must explicitly check the value of the Android.

SdkInt property to determine the API level of the platform the app is running on. For example, let's suppose that we want to use the NotificationBuilder. SetCategory method to categorize a notification when running on Android 5. Referring to the Android version table at the beginning of this guide, we see that the build version code for Android 5. To support older versions of Android where SetCategory is not available, our code can detect the API level at runtime and conditionally call SetCategory only when the API level is greater than or equal to the Lollipop build version code:.

In this example, our app's Target Framework is set to Android 5. Lollipop and later, this example code will call SetCategory only when it is actually available — it will not attempt to call SetCategory when the API level is 16, 17, 18, 19, or The functionality is reduced on these earlier Android versions only to the extent that notifications are not sorted properly because they are not categorized by type , yet the notifications are still published to alert the user.

Our app still works, but its functionality is slightly diminished. In general, the build version check helps your code decide at runtime between doing something the new way versus the old way. For example:. There's no fast and simple rule that explains how to reduce or modify your app's functionality when it runs on older Android versions that are lacking one or more APIs. In some cases such as in the SetCategory example above , it's sufficient to omit the API call when it's not available.

However, in other cases, you may need to implement alternate functionality for when Android. SdkInt is detected to be less than the API level that your app needs to present its optimum experience. When you create a Xamarin. Android library project such as a class library or a bindings library , you can configure only the Target Framework setting — the Minimum Android version and the Target Android version settings are not available.

That is because there is no Android Manifest page:. Android library project, there is no Android Application page where you can configure the Minimum Android version and the Target Android version — the Minimum Android version and Target Android version settings are not available. The Minimum Android version and Target Android version settings are not available because the resulting library is not a stand-alone app — the library could be run on any Android version, depending on the app that it is packaged with.

You can specify how the library is to be compiled , but you can't predict which platform API level the library will be run on. With this in mind, the following best practices should be observed when consuming or creating libraries:.

When consuming an Android library — If you are consuming an Android library in your application, be sure to set your app's Target Framework setting to an API level that is at least as high as the Target Framework setting of the library.

When creating an Android library — If you are creating an Android library for use by other applications, be sure to set its Target Framework setting to the minimum API level that it needs in order to compile.
