New Features, API & Security:

Display Cutout API: Based on the continuous innovation with screens, the new API is been developed for Curved & Waterfall screens.

Bubbles API: Bubbles are a way to keep conversations in view and accessible while multi-tasking on their phones. Messaging and chat apps should use this on notifications to enable this in Android 11.

Scoped Storage: As it all started from Android 10, the features are enhanced now such as opt-in raw file path access for media, updated Documents UI, and batch edit operations in MediaStore.

Permissions dialog that includes Only this time option

Permissions: Android 11 is being more transparent with permissions and for that new features are added as Data Access Auditing. By this feature, end users will better identify & rectify potentially unexpected data access. Another is Dialog Visibility which says, by tapping “Deny” twice for specific permission, it will be considered as “don’t ask again” subsequently.

Also, the new One Time Permission contains an option called “Only this time” for temporary one-time permission. Moreover, if the app targets Android 11, you cannot directly request all-the-time access to background location.

Bio-metric Authentication Strength: Android 11 introduces the BiometricManager.Authenticators interface. Also the AuthenticationResult API allows you to check whether the user authenticated using bio-metric or device credentials.

Neural Networks API 1.3: Neural Networks API (NNAPI) is designed for running computationally intensive operations for machine learning on Android devices. In Android 11, the operations and controls are expanded and available to developers.

In this release, some new operations and execution controls are added to help optimize common use cases:

• Quality of Service APIs support priority and timeout for model execution.
• Memory Domain APIs reduce memory copying and transformation for consecutive model execution.
• Expanded quantization support, we’ve added signed integer asymmetric quantization where signed integers are used in place of float numbers to enable smaller models and faster inference.

Migration & Compatibility

The Android 11 Preview SDK includes changes that are not compatible with some older versions of Android Studio. So, for the best development experience with the Android 11 Preview SDK, It is recommended that you install the latest preview version of Android Studio 4.0 Preview.

Though you can compile and test Android 11 apps using Android Studio 3.3 and higher. After all these, you can configure the build and access the features subsequently.

Testing

Android 11 introduces new tools for testing and debugging your app against the behavior changes in the latest version of the platform. The main purpose of the compatibility framework is to provide you with control and flexibility as you test your app with a new version of Android.

One should toggle “OFF” while changing all the apps and should toggle “ON” while targeting specific SDK version. There are some restrictions too.

Things To Remember: Implementing Android 11 in your projects at this time can affect the behaviors.
