|---|---|
Compatibility with previous versions of the SDK | The BlackBerry Dynamics SDK for Android is compatible with these previous releases of the SDK:
|
Supported Android OS | Android 9.0 or later |
Android API Level | Minimum API level: 28 |
AndroidX libraries | Your apps must use the AndroidX support libraries to compile successfully. The SDK supports the following minimum versions. It is recommended to use the latest stable version of each library.
|
Build requirements |
|
Google
Play Services | The SDK uses Google
Play Services version 17.0.0 to support some of its functionality.If your app uses the following Google
Play Services libraries, verify that you are using the following minimum version or later:
|
Supported CPU architectures |
|
Java compatibility | Applications must be built using Java 8 compatibility. For more information, see java8-support. |
Suggested versions of platform and tools |
|
Package visibility restrictions | Package visibility updates were made in SDK version 8.1 and later to address changes in Android 11 to how apps query and interact with other apps that are installed on the same device. These changes impact apps with the target SDK level set to Android 11 or later only (targetSDKLevel=Android 11). If a BlackBerry
Dynamics app is not upgraded to SDK version 8.1 and you change the target SDK level to Android 11, the app cannot communicate with other BlackBerry
Dynamics apps on the same device, breaking interoperability features (Easy Activation, authentication delegation, and so on).To support the new package visibility queries element, you must either upgrade the Android Gradle plugin to version 3.6.3 or later or follow the instructions from the Android Developers Blog: Preparing your Grade build for package visibility in Android 11 to use a major Gradle version with the latest dot release.Apps that target Android 11 are able to perform interoperability operations with the apps that don't target Android 11. Apps that are not targeted to Android 11 can run on Android 11 and are not affected by the package visibility restrictions. |
Character encoding for build files | Build files (for example, settings.json) must use UTF-8 character encoding. Verify that the editor that you plan to use does not add non-UTF-8 characters or headers. In general, Java does not work with UTF-8-BOM (byte order mark). |
Supported launch modes | Apps built with the BlackBerry Dynamics SDK for Android support the following launch modes in AndroidManifest.xml:
|
BlackBerry Dynamics Launcher Library | The BlackBerry Dynamics Launcher is a user-friendly interface that allows users to easily access and switch between BlackBerry
Dynamics apps, configure app settings, and take advantage of other useful features. For more information, see the BlackBerry Dynamics Launcher Framework documentation.The BlackBerry Dynamics SDK and the BlackBerry Dynamics Launcher Library are mutually dependent. See the BlackBerry Dynamics SDK for Android Release Notes for the required version of the BlackBerry Dynamics Launcher Library . |
Restricted key prefix | The key prefix "blackberry" is reserved by BlackBerry and should not be used for key values, key attributes, or key elements. For more information and examples, see the Application Policies Definition in the appendix of the API Reference. |
Credential manager requirements | Apps that will use the Credential Manager UI require the following updates:
