Survicate Android SDK

The Survicate Android SDK will increase your app's size by approximately 4MB when obfuscated and uncompressed. Note that the SDK features a Time To Live (TTL) mechanism of 60 seconds. This means any modifications made to your survey will be reflected on your respondents' devices after a delay of up to 60 seconds.

Requirements:

  • Using Survicate Mobile SDK requires an account at survicate.com. You can create your account here for free, or become invited to your company account by one of your colleagues.
  • Android Gradle plugin in version 3.0.0+.
  • Compatibility with Java 8 language features.
  • Respondent's device running Android version 5 or above.

Installation

Installing using Maven

The recommended installation method.

  1. Define https://repo.survicate.com Maven repository in one of the following ways:
  1. Add Survicate SDK dependency to your app's build.gradle file.

Installing manually

  1. Download Survicate for Android
  2. Copy Survicate.aar to app/libs directory of your project.
  3. Add dependencies for manual installation to your app's build.gradle file:
Show dependencies

Note: Keep in mind that when updating the version by manual installation, you need to update SDK dependencies versions too.


Configuration

The following configuration will require workspace key. You can get your workspace key in the Access Keys section of the Survicate panel.

  1. Configure your workspace key in AndroidManifest.xml file. Create meta-data: com.survicate.surveys.workspaceKey.
  2. Initialize the SDK in your application class using init() method. If your project doesn't have a custom application class yet, you'll need to create one. Make sure that your custom application class is defined in AndroidManifest.xml.

As an alternative to the main way of specifying the Workspace Key, you can also use the setWorkspaceKey() method.

Important:

  • Using setWorkspaceKey() method overrides the Workspace Key defined in the configuration.
  • setWorkspaceKey() method must be used before init() method is called.

ProGuard (optional)

The SDK provides built-in proguard rules, so you don't have to specify them manually.

Included rules

Since 2.0.0 Survicate Android SDK depends on Coil library. Please refer to Coil website for more information about their proguard rules.

We recommend using the most recent version of Gradle with R8 enabled in gradle.properties file:


Using SDK

Survicate allows you to launch precisely targeted surveys inside your app. In the Survicate Panel, you can set conditions that need to be met for the surveys to appear. Users matching conditions defined in the Survicate panel will see the survey automatically. Here's a list of conditions you can use to target your surveys:

  • Name of the screen that a user currently sees
  • Any application event
  • User attributes and identities
  • Device language
  • Operating system

Make sure to list all the screens and events described in your application. Once you got this covered, you or any person responsible for creating and managing surveys will be able to trigger surveys from the Survicate panel with no need for you to update the application.

Warning Warning The SDK utilizes SharedPreferences to store information used by the targeting engine described in this section. Clearing SharedPreferences will cause the targeting system to malfunction; f.e. by showing the same survey twice to a single user.

Targeting a survey by screen name

A survey can appear when a user is viewing a specific screen. For example, a survey can be triggered to show up on the application's home screen after a user spends more than ten seconds there. To set it up, you need to send information to Survicate about the user entering and leaving a screen.

Note: Multiple active screens are allowed. In specific, calling enterScreen() does not make the previous screen to be discarded. Be sure to call leaveScreen() when you no longer want the screen to be treated as active.

Screen name is case sensitive. If there's any discrepancy between what's declared in the ‘Screens’ tab of the Target section in the Survicate panel and the application code, the survey will not appear.

Events-based survey targeting

Survicate Android SDK allows you to launch surveys based on events your users trigger in your app. Your survey will show instantly after an event occurs in your app.

Event name is case sensitive. If there is any discrepancy between what's declared in the ‘Triggers’ tab of the Target section in the Survicate panel and the application code, the survey will not appear.

User identification & attributes

You can pass user attributes to Survicate as an additional layer of information about your users. Attributes can be used to:

  • Identify respondents (by default survey responses are anonymous).
  • Target surveys to specific users with Audience filters.
  • Recall information in survey questions (e.g. include user name).
  • Filter survey results.

Bear in mind that user attributes are cached. You only need to provide them once, e.g. when user logs in, not after each init(). You can also change their values at any time to trigger a survey.

Attribute types

  • String: any text, e.g. user name or e-mail.
  • Number: an integer or decimal.
  • Boolean: a logic value.
  • Date: a java.util.Date that can be used in date or time interval filters (the latter measure elapsed time from a given timestamp).

Additional notes

  • You can freely use custom attribute keys without the need to register them anywhere. However, the "user_id" has an additional meaning: it corresponds to the "known user" in the panel's Audience filter. A user is considered known when a trait with the "user_id" key has been set on the device (the value doesn't matter).

  • In some panel functionalities (e.g. autocompletion), the attribute key will be available only after a survey response with the given attribute is uploaded (unless the key was added in the panel manually). By that time, the trait is saved only locally on the user's device.

  • Note that the predefined attribute classes (UserTrait.UserId, UserTrait.FirstName, etc.) have been deprecated in version 4.0. Instead, you should use the UserTrait(key, value) constructor. You will find migration details in the deprecation messages.

Reseting user data for testing purposes

If you need to test surveys on your device, reset() method might be helpful. This method will reset all user data stored on your device (survey views, attributes, information about answered surveys for the targeting engine).

Event listeners

SDK allows you to utilize event listeners. You may find them useful to trigger actions in your application based on actions performed by respondents. Here's a list of events you can subscribe to:

  • survey_displayed - occurs when survey is loaded and appears in the User Interface
  • question_answered - occurs after a question is answered ( Survicate stores incomplete survey submissions )
  • survey_closed - occurs when a user closes the survey using the close button
  • survey_completed - occurs when a user finishes the survey

SurvicateAnswer properties (QuestionAnsweredEvent.answer)

PropertyTypeDescription
typeStringAnswer type. One of: ['text', 'single', 'multiple', 'smiley_scale', 'rating', 'csat', 'numerical_scale', 'nps', 'date', 'form', 'button_close', 'button_next', 'button_link'].
idLong?Answer ID. Applicable only for types: ['single', 'smiley_scale', 'csat', 'rating', 'numerical_scale'].
idsSet<Long>?Selected answer IDs. Applicable only for type = ['multiple'].
valueString?Text representation of an answer, e.g. "Happy" for smiley scale. Not applicable for call-to-action answers: ['button_close', 'button_next', 'button_link'].

The id, ids and value properties are provided only for the cases enlisted in the table above. Therefore, expect that there might be answer objects that consist only of the type property.
