Added

Added support for Heap Contentsquare Bridge SDK.

[0.5.2] - 2024-03-21

Fixed

Fixed a bug introduced in 0.5.0 that prevented Mobile Library Version from being properly captured.
- Customers should skip versions 0.5.0 and 0.5.1 in favor of 0.5.2 to prevent gaps in Mobile Library Version capture.

[0.5.1] - 2024-02-23

Fixed

Fixed a bug where switching between environment IDs could prevent events from being stored properly.
Fixed a bug where native events would set the session expiration back to five minutes after a WebView event extended it to 30 minutes.

Added

Added support for tracking pageviews across a JavaScript bridge.
Added support for tracking interactions across a JavaScript bridge.

[0.5.0] - 2024-01-08

Added

Added an option to capture vendor ID from Google App Set ID.
Added an option to configure the number of messages sent in each upload batch.
Added an option to configure whether event properties should be cleared when the current user changes.
Added new artifacts to enable non-core functionality.
- io.heap.core.identifier:ad-id-google
- io.heap.core.identifier:ad-id-amazon
- io.heap.core.identifier:vendor-id-google
- io.heap.core.web:webview-heapjs

Changed

Android Core no longer includes dependencies for advertiser ID and WebView sessionization behaviors. If attempting to capture advertiser ID, you must add one of the above advertiser ID capture artifacts. You must also include the WebView artifact to enable WebView session sharing.
Updated the networking layer to continue sending events when receiving a 400 response code from Heap to allow data replay capabilities.
Event properties are no longer cleared when switching the active user. To retain the old behavior and clear event properties when changing users, set the clearEventPropertiesOnNewUser initialization option.

[0.4.0] - 2023-09-25

Added

Added an option to disable accessibility label capture.
Added a builder to Options to make setting options easier in Java apps.

Changed

Heap.addEventProperties no longer attaches properties to session messages.

Added support to track app version changes.

[0.2.0] - 2023-05-15

Fixed

Fixed a race condition that could prevent capture of the Android Advertiser ID property.

Changed

Changed the default behavior of Heap.startRecording to delay the start of a session until an event or pageview occurs. In order to override the default behavior and start a session immediately, initialize an Options instance with startSessionImmediately set to true and invoke Heap.startRecording with that Options instance. NOTE: If you are using the Heap Android View Autocapture SDK, you must also upgrade that dependency's version to 0.2.0.
Kotlin dependencies updated to version 1.8.x. Implementing apps will need to update their Kotlin plugin version to 1.8.0 or higher.

[1.1.0] - 2019-06-29

Changed

Sessions now last for five minutes since the last interaction, instead of restarting whenever the app reenters the foreground

[1.0.1] - 2019-06-29

[0.9.1] - 2019-03-25

Fixed

[0.9.0] - 2019-03-21

Added

Allow ignoring events from parts of the view hierarchy, both declaratively
via XML view tags, and programmatically by calling Heap.ignore() on the
view.
Capture page transition events for changes to the visible page in a
ViewPager.
Heap now captures events for androidx equivalents of support library
elements.

Changed

compatibility, but the ext.heap map location is deprecated.
The Heap Gradle plugin can now also be applied before the Android Gradle
plugin if using Gradle >= 4.8.
The Heap Gradle plugin attempts to reduce configuration overhead by using
the task configuration avoidance APIs when used with Android Gradle Plugin
versions 3.3 and higher.

removed in a future version; use ext.heapEnabled instead.
Support for Android Gradle Plugin versions earlier than 3.0.0 is deprecated
and will be removed in a future release.

Fixed

Fix an issue with EditText change events sometimes having incorrect
timestamps, leading to dropped events.
Fix potential issue with tracking changes to set of visible fragments.

[0.8.3] - 2019-01-23

TextWatcher added

Request bodies are now compressed with gzip for size efficiency

Fixed

Heap no longer captures duplicate events for certain app architecture patterns

[0.8.2] - 2019-01-05

Added

Heap client library now specifies a target SDK version, which prevents the
manifest merger from automatically adding the implicit system permissions
READ_PHONE_STATE, READ_EXTERNAL_STORAGE, and WRITE_EXTERNAL_STORAGE to
users' apps

[0.8.1] - 2018-12-17

Fixed

Heap plugin works for Android Gradle Plugin version 3.2.1.
Heap plugin instruments Android App Bundles (note: dynamic modules are not supported).

[0.8.0] - 2018-12-05

Added

Heap now autocaptures when fragments are added or removed from view, and
includes visible fragments as an event property on all events

Changed

Heap plugin looks for the heap extension on flavors and default config as
well as build types
The Gradle plugin will error out if used with Android Gradle Plugin 3.2.0 or
higher. This is a temporary measure as we add compatibility for AGP 3.2+ and
app bundles.

Removed

Heap no longer sends session and pageview events if the build plugin did not
apply Heap properly, or if the app is running under instant run. This was
confusing when troubleshooting, as seeing some events could make it look like
Heap was installed properly when it was not.

Fixed

Fixed an issue with the included proguard rules that could result in a
NoSuchMethodError at runtime

[0.7.5] - 2018-10-15

Added

Proguard rules are now bundled in the client library, removing the need to
add them manually when integrating

Changed

Heap library now includes device form factor with event data.
