Interface Context
Provides APIs to handle data campaigns, track Item views and interactions, and track manual actions, all within a lifecycle-managed context such as Screen
.
Typically used as Evergage.getScreenForActivity(android.app.Activity)
, and if necessary, Evergage.getGlobalContext()
for behavior outside of an Activity.

Whether this context is active or not.
A typical Screen context is active when Screen.isRunning()
and the app and user are active.
Besides some initial setup just before becoming visible (setCampaignHandler(com.evergage.android.CampaignHandler, java.lang.String)
, viewItem(com.evergage.android.promote.Item)
, and so on), activity generally occurs while a context is active. Context activity, in addition to app state and user idleness, can affect campaign delivery. For more information, see setCampaignHandler(com.evergage.android.CampaignHandler, java.lang.String)
.
Returns
true
, if this context is active.
To optionally support custom data campaigns, register a campaign handler for the app-defined target within this context. Can set a null
handler for a target to clear.
The "target" is an app-defined string that uniquely identifies the payload data schema - what the data represents and its purpose. See Campaign.getTarget()
.
While the context, app, and user are active, the handler can receive asynchronous callbacks (on the main thread) with campaigns for the target, in response to actions or events sent. The handler code must show or update the campaign to the user, when appropriate. For example code, see CampaignHandler
.
Campaigns can be held for delivery while either:
- The context, app, or user is inactive
- No handler is found for the campaign's target within this context
For each context and target, only the most recent campaign is held.
Lifecycle details:
- For an Activity, it’s recommended to always get
Evergage.getScreenForActivity(Activity)
and call this method just before becoming visible, specifically inonStart()
. For example code, seeCampaignHandler
. - In order to prevent accidental leaks in the
CampaignHandler
, a Screen has a limited time to become visible, after which its handlers and held campaigns are cleared. - When a screen transitions to not visible
onStop()
, all handlers and held campaigns are cleared.
Parameters:
Parameter | Description |
---|---|
handler | The campaign handler this context must use for the specified target. |
target | App-defined string that uniquely identifies the payload data schema - what the data represents and its purpose. For more information, see Campaign.getTarget() . |
See Also
Tracks an impression for the provided data campaign. Call this method after showing the campaign to the user or if the campaign would be shown but the user is in the control group. For more information, see Mobile Data Campaigns and CampaignHandler
.
Parameters:
Parameter | Description |
---|---|
campaign | The campaign for which an impression should be tracked. |
See Also
Tracks a dismissal for the provided data campaign. Call this method after showing the campaign to the user and the user dismissed the campaign. For more information, see Mobile Data Campaigns and CampaignHandler
.
Parameter | Description |
---|---|
campaign | The campaign for which a dismissal should be tracked. |
See Also
Tracks a clickthrough for the provided data campaign. Call this method after showing the campaign to the user and the user clicked campaign content. For more information, see Mobile Data Campaigns and CampaignHandler
.
Parameters
Parameter | Description |
---|---|
campaign | The campaign for which a clickthrough should be tracked. |

Track an uncommonly handled push notification clickthrough that can't be automatically tracked.
Personalization automatically tracks clicks/opens from Firebase notifications received in the background, and from Firebase notifications received in the foreground that your app chooses to handle by launching an activity in the default launchMode
"standard" (for example, intent did not have flags such as FLAG_ACTIVITY_CLEAR_TOP
). Any Activity using a different launchMode
can enable tracking by calling setIntent
within onNewIntent
, as shown in the following example.
This tracking method may be required if you manually render a notification from the push. For example, if the Firebase notification is received while the app is in the foreground, it is not automatically shown - instead FirebaseMessagingService#onMessageReceived
is called. At this point your app can decide if it wants to manually show a notification. For example code using notifications, see trackClickthrough(Intent)
.
The following code example uses an AlertActivity
/Dialog
.
Parameters
Parameter | Description |
---|---|
notificationData | Pass remoteMessage.getData() , after it's been manually rendered and clicked. |

Tracks that an item is being viewed.
Set null

or viewItemDetail(com.evergage.android.promote.Item)
are called again.

Since
1.4.0
Tracks that an order was purchased. If the order contains no lineItems

order | The order that was purchased. Each LineItem.item should be a Product with a set Product.price . |

Sends an event to Personalization describing an action to track. When considering the action name, remember that datasets encompass multiple platforms and apps. The name can match a corresponding action/behavior from another platform/app. A campaign can use a source rule to be limited to a specific source or set of sources. For information on recommended rules, see Mobile Data Campaigns.
Actions sent from this context (including Item APIs) can potentially receive a campaign in response, delivered to a handler via setCampaignHandler(com.evergage.android.CampaignHandler, java.lang.String)
.
Parameters
Parameter | Description |
---|---|
action | A short string that identifies the action. |
