Android SDK Initialization

Initializing the SDK



Initialize the SDK on the main thread inside onCreate() and not create a worker thread and initialize the SDK on that thread.

import com.moengage.capacitor.MoEInitializer;
import com.moengage.core.MoEngage;
import com.moengage.core.DataCenter;

public class MainApplication extends Application {

  @Override public void onCreate() {
// this is the instance of the application class and "YOUR_APP_ID" is the APP ID from the dashboard.
MoEngage.Builder moEngage = new MoEngage.Builder(this,"YOUR_APP_ID”, [YOUR_DATA_CENTER]);
MoEInitializer.initialiseDefaultInstance(this, moEngage);

Following details of the different data centers you need to set based on the dashboard hosts

Data Center Dashboard host






For more information about the detailed list of possible configurations, refer to the API reference.



All the configurations are added to the builder before initialization. If you are calling initialize at multiple places, ensure that all the required flags and configurations are set each time you initialize to maintain consistency in behavior.

In case your application does not have an Application class yet navigate to the java source code inside the android platform folder and add the Application class file.


Make sure your application class is defined in the AndroidManifest.xml file as well.

Register MoEngage's Plugin

Register the plugin in your Activity class's onCreate().

import com.getcapacitor.BridgeActivity;
import com.moengage.capacitor.MoECapacitorCorePlugin;

public class MainActivity extends BridgeActivity {

  @Override protected void onCreate(Bundle savedInstanceState) {
    //register the MoEngage Capacitor Plugin

Exclude MoEngage Storage File from Auto-Backup

This is a mandatory integration step and is very essential to prevent your data from getting corrupted. Android's auto back-up service periodically backs up Shared Preference files, Database files, etc, more details here. This backup results in MoEngage SDK's identifiers being backed up and restored after re-install.This restoration of the identifier results in your data being corrupted and users not being reachable via push notifications.

To ensure data is not corrupted after a backup is restored, opt out of MoEngage SDK's storage files. Refer to Exclude MoEngage Storage File from the Auto-Backup section of the documentation to learn more about which files to exclude.
