Android 6. This document provides an introduction to the most notable APIs. To start building apps for Android 6. To better optimize your app for devices running Android , set your targetSdkVersion to "23" , install your app on an Android system image, test it, then publish the updated app with this change.
To learn more about maintaining backward compatibility, read Supporting Different Platform Versions. This release offers new APIs to let you authenticate users by using their fingerprint scans on supported devices, Use these APIs in conjunction with the Android Keystore system. To authenticate users via fingerprint scan, get an instance of the new FingerprintManager class and call the authenticate method.
Your app must be running on a compatible device with a fingerprint sensor. You must implement the user interface for the fingerprint authentication flow on your app, and use the standard Android fingerprint icon in your UI. To see an app implementation of fingerprint authentication, refer to the Biometric Authentication sample.
On Windows, you may have to run telnet Your app can authenticate users based on how recently they last unlocked their device. This feature frees users from having to remember additional app-specific passwords, and avoids the need for you to implement your own authentication user interface. Your app should use this feature in conjunction with a public or secret key implementation for user authentication.
To set the timeout duration for which the same key can be re-used after a user is successfully authenticated, call the new setUserAuthenticationValidityDurationSeconds method when you set up a KeyGenerator or KeyPairGenerator.
Avoid showing the re-authentication dialog excessively -- your apps should try using the cryptographic object first and if the timeout expires, use the createConfirmDeviceCredentialIntent method to re-authenticate the user within your app.
This feature allows you to associate an app with a web domain you own. Based on this association, the platform can determine the default app to use to handle a particular web link and skip prompting users to select an app.
To learn how to implement this feature, see Handling App Links. Auto Backup for Apps The system now performs automatic full data backup and restore for apps. Your app must target Android 6.
If users delete their Google accounts, their backup data is deleted as well. To learn how this feature works and how to configure what to back up on the file system, see Configuring Auto Backup for Apps. This release provides you with APIs to make sharing intuitive and quick for users.
You can now define direct share targets that launch a specific activity in your app. These direct share targets are exposed to users via the Share menu. This feature allows users to share content to targets, such as contacts, within other apps. For example, the direct share target might launch an activity in another social network app, which lets the user share content directly to a specific friend or community in that app.
To enable direct share targets you must define a class that extends the ChooserTargetService class. Declare your service in the manifest.
The following example shows how you might declare the ChooserTargetService in your manifest. This release provides a new voice interaction API which, together with Voice Actions , allows you to build conversational voice experiences into your apps. Call the isVoiceInteraction method to determine if a voice action triggered your activity.
If so, your app can use the VoiceInteractor class to request a voice confirmation from the user, select from a list of options, and more.
Most voice interactions originate from a user voice action. Check out the announcement blog post. The software development kit SDK includes everything you need to build and run. NET applications, using command-line tools and any editor like Visual Studio. Run apps - Runtime Tooltip: Do you want to run apps?
The runtime includes everything you need to run. NET applications. The runtime is also included in the SDK. NET Core Runtime 6. NET Core Module v2 It works along with Build tools for encryption, security, and file size purposes. One of the tools included in this group is the Android Debug Bridge adb. It can be used to install an Android app file on any of your devices and allows you to access additional shell tools like bmgr and logcat.
This emulator is a QEMU-based device-emulation tool that allows you to debug and test your apps in an actual Android runtime environment even without using any physical devices.
Running the emulator will require you to have a system image, an additional tool to your toolset. Each platform version contains the supported system images. This is where Android Studio comes in, it allows you to compile and edit your code, or test your app before releasing it on Google Play. Installing Android Studio is also the easiest way to get a working set of tools on your PC. This set of Android development tools is easy to set up and run. The whole process using this toolset is not intuitive enough for novice app developers.
However, there are lots of available documentation and tutorials online that can help in assisting you in using Android SDK. You can download the toolset for free. The first one requires you to download the whole Android Studio file which already contains the toolset and other Android development tools.
Taking advantage of this, developers can now start to tweak their existing apps and making them ready for the public release of Marshmallow. You can now run and test your apps on Nexus 5, 6, Nexus 9, and Nexus Player as well as emulator. He also mentioned that the developers will receive multiple updates during the Preview to help them test against the latest platform changes. Along with the new platform features like fingerprint support and Doze power saving mode, Android Marshmallow features a new permissions model that streamlines the app install and update process.
