Android changelog

Version 3.0.0 (2020-06-10)

This is a major release and it is not backward compatible with the previous ones.

Version 2.4.0 (2020-03-18)

Version 2.3.2 (2020-03-11)

This version fixes a bug that could prevent sensor data from being transmitted to our server.

Version 2.3.1 (2020-02-13)

Version 2.3.0 (2020-02-12)

IMPORTANT:

The OS will automatically grant this permission to existing apps. However, this is not the case for new app installs, therefore developers must request this permission before starting the SDK.

A few helper functions were added to help developers with the task of verifying and requesting the correct permissions and location settings:

MotionTag.hasRequiredLocationSettings(): Checks if the device has all the required location settings.

MotionTag.hasRequiredPermissions(): Checks if the app has all the required permissions.

MotionTag.getRequiredPermissions(): Returns an array with all the required permissions.

MotionTag.requestRequiredLocationSettings(Activity activity, int requestCode): Displays a dialog that allows users to enable all the required location settings.

MotionTag.requestRequiredPermissions(Activity activity, int requestCode): Requests the required runtime permissions to the user.

Please check our documentation for more information.

Version 2.2.7 (2020-01-27)

Version 2.2.6 (2020-01-16)

Version 2.2.5 (2020-01-15)

Version 2.2.4 (2020-01-07)

Version 2.2.3 (2019-12-05)

Version 2.2.2 (2019-11-12)

Version 2.2.1 (2019-10-03)

Version 2.2.0 (2019-09-13)

IMPORTANT:

Starting from version 2.2.0, the SDK requires compileSdkVersion 29 or higher. Apps targeting API 29 must request both android.permission.ACCESS_FINE_LOCATION and android.permission.ACCESS_BACKGROUND_LOCATION runtime permissions, otherwise the SDK will not work properly on Android 10.

After requesting the location permissions, Android 10 users will get a dialog with 3 different options to choose from. Users must select "Allow all the time" option, otherwise the SDK won't function properly.

Returns Method Explanation
void onAutoStart(Reason.Start reason) Informs the application that tracking has been automatically started.
void onAutoStop(Reason.Stop reason) Informs the application that tracking has been automatically stopped.
void onLocation(Location location) Hands the latest captured android.location.Location. to the application.
void onTransmission(long timestamp) Informs when a package of events has been successfully sent to the server. The timestamp parameter represents the time (in milliseconds) of the server confirmation response.

TO

Returns Method Explanation
void onEvent(Event event) Informs the application about a new incoming event.
Event Explanation
AutoStart(Reason.Start reason) Event informs application that tracking has been automatically started.
AutoStop(Reason.Stop reason) Event informs application that tracking has been automatically stopped.
LocationEvent(Location location) Event hands the latest captured android.location.Location. to the application.
Transmission(long timestamp) Event informs when a package of events has been successfully sent to the server. The timestamp parameter represents the time (in milliseconds) of the server confirmation response.
