Before I start

Piano Analytics SDKs have been designed for the Piano Analytics solution. Data sent through these SDKs will not be processed within the Analytics Suite 2.

Integrate the library

The first step to use our SDK is to integrate our library in your project. You have multiple ways to do this.


Add this following line in your build.gradle file (app-level) under dependencies:

implementation 'io.piano:analytics:3.x.x' // replace 3.x.x with the version you target


  1. Clone the Android SDK from our Github repository:

    • SSH:
    • HTTPS:
  2. From your Android Studio

    • Go to File > Project Structure > Modules
    • Click on the plus sign + and go to Import...
    • Search for the cloned directory and select the piano-analytics folder
    • Click on Finish
  3. After a sync of Gradle you might have an error like 'Build was configured to prefer settings repositories over project repositories'

    • Open your project-level settings.gradle file and replace/add the repositoriesMode as below
      • repositoriesMode.set(RepositoriesMode.PREFER_SETTINGS)
    • Resync Gradle
  4. As a support to Huawei in our SDK, you might also have a warning on sync (error on build) talking about a library from com.huawei.hms

    • For Gradle plugin earlier than 7.0

      • Open your project-level build.gradle file
      • Add the Maven repository as below under buildscript > repositories and allproject > repositories
        • maven {url ''}
    • For Gradle plugin 7.0

      • Open your project-level build.gradle file
      • Add the Maven repository as below under buildscript > repositories
        • maven {url ''}
      • Open your project-level settings.gradle file
      • Add the Maven repository as below under dependencyResolutionManagement > repositories
        • maven {url ''}
    • For Gradle plugin 7.1 or Later

      • Open your project-level settings.gradle file
      • Add the Maven repository as below under pluginManagement > repositories and dependencyResolutionManagement > repositories
        • maven {url ''}

piano-analytics should now be recognized as a library

Instantiate tracker

First of all, you should ensure that your app permissions are correctly set. You need the following permissions in your AndroidManifest.xml:

<!-- Allow the application to send events to Piano Analytics -->
<uses-permission android:name="android.permission.INTERNET" />

<!-- Allow to check network condition before trying to send events -->
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

Our Android SDK requires you to instantiate a tracker before using it.

You should pass the application context as a parameter.

PianoAnalytics pa = PianoAnalytics.getInstance(getApplicationContext());


In order to setup your tracking, you need to set the configuration of the library:

func PianoAnalytics.setConfiguration(config);

Here is the minimal configuration required:

pa.setConfiguration(new Configuration.Builder()

Don't hesitate to read our collection methods article to find the collection domain that has been assigned to you.

You can also use a custom domain thanks to our CDDC.

Here are the available configurations:
