Not Helpful 13 Helpful The launcher indicates that work apps and widgets are not accessible. Device owners and profile owners can ensure that work apps always connect through a specified VPN.
The system automatically starts that VPN after the device boots. As before, services are indicated to the system by an intent filter matching action android. An application can customize the profile owner and device owner provisioning flows with corporate colors and logos. This makes it much easier for users to discover and configure accessibility features on their devices, including magnification gesture, font size, display size, and TalkBack.
With these accessibility features getting more prominent placement, your users are more likely to try your app with them enabled. Make sure you test your apps early with these settings enabled. Also in Android 7. The new API allows building services with features such as face-tracking, eye-tracking, point scanning, and so on, to meet the needs of those users.
For more information, see the reference documentation for GestureDescription. Direct boot improves device startup times and lets registered apps have limited functionality even after an unexpected reboot. For example, if an encrypted device reboots while the user is sleeping, registered alarms, messages and incoming calls can now continue to notify the user as normal.
This also means accessibility services can also be available immediately after a restart. Direct boot takes advantage of file based encryption in Android 7. The system uses a device-encrypted store for select system data and explicitly registered app data. By default a credential-encrypted store is used for all other system data, user data, apps, and app data.
At boot, the system starts in a restricted mode with access to device-encrypted data only, and without general access to apps or data. If you have components that you want to run in this mode, you can register them by setting a flag in the manifest. The system ensures registered device-encrypted app data is available before unlock. All other data is unavailable until the User confirms their lock screen credentials to decrypt it.
By using this tool, you gain additional confidence that your app interacts with keys that reside in secure hardware, even if the device running your app is rooted.
If you use keys from the hardware-backed keystore in your apps, you should use this tool, particularly if you use the keys to verify sensitive information within your app.
The tool also allows you to use an off-device service, such as your app's back-end server, to determine and strongly verify the uses and validity of the key pair. These features provide an additional level of security that protects the key pair, even if someone roots the device or compromises the security of the Android platform running on the device. Note: Only a small number of devices running Android 7.
Before you verify the properties of a device's hardware-backed keys in a production-level environment, you should make sure that the device supports hardware-level key attestation. To do so, you should check that the attestation certificate chain contains a root certificate that is signed by the Google attestation root key and that the attestationSecurityLevel element within the key description data structure is set to the TrustedEnvironment security level.
For more information, see the Key Attestation developer documentation. For more information, see Network security configuration. By default, apps that target Android 7. Apps targeting Android 7. By default, Android Studio 2. Although we recommend applying APK Signature Scheme v2 to your app, this new scheme is not mandatory. If your app doesn't build properly when using APK Signature Scheme v2, you can disable the new scheme.
The disabling process causes Android Studio 2. To sign with only the traditional scheme, open the module-level build. Caution: If you sign your app using APK Signature Scheme v2 and make further changes to the app, the app's signature is invalidated.
For this reason, use tools such as zipalign before signing your app using APK Signature Scheme v2, not after. For more information, read the Android Studio documents that describe how to sign an app in Android Studio and how to configure the build file for signing apps using the Android Plugin for Gradle.
The new APIs greatly simplify how your application accesses standard external storage directories, such as the Pictures directory. Additionally, the new APIs simplify the steps a user takes to grant external storage access to your app. When you use the new APIs, the system uses a simple permissions UI that clearly details what directory the application is requesting access to. For more information, see the Scoped Directory Access developer documentation.
You can also provide your own fine-tuned shortcuts lists for the screen. You can do this by overriding the , android. To trigger Keyboard Shortcuts Helper from anywhere in your app, call requestShowKeyboardShortcuts from the relevant activity.
This capability is especially useful when a user is using a mouse or touchpad to interact with UI objects. The default pointer uses a standard icon. This API also includes advanced functionality such as changing the pointer icon's appearance based on specific mouse or touchpad movements.
To set a pointer icon, override the onResolvePointerIcon method of the View class. This method uses a PointerIcon object to draw the icon that corresponds to a specific motion event. Performance can fluctuate dramatically for long-running apps, because the system throttles system-on-chip engines as device components reach their temperature limits. This fluctuation presents a moving target for app developers creating high-performance, long-running apps.
To address these limitations, Android 7. App developers can use these hints to tune apps for a predictable, consistent level of device performance over long periods of time. App developers can try out this new API in Android 7. To use this feature, set the sustained performance window flag for the window you want to run in sustained performance mode.
Set this flag using the Window. The system automatically disables this mode when the window is no longer in focus. There are a number of performance enhancements, including access to an exclusive CPU core for VR apps.
Within your apps, you can take advantage of intelligent head-tracking, and stereo notifications that work for VR. Most importantly, Android 7.
