# Android SDK Initialization

> Initialize the MoEngage SDK in your Android application's onCreate method for Cordova integration.

# Initialization

Get the Workspace ID from the **Settings Page Dashboard --> Settings --> App --> General** on the MoEngage dashboard and initialize the MoEngage SDK in the **Application** class's **onCreate()**

<Info>
  It is recommended that you initialize the SDK on the main thread inside **onCreate()** and not create a worker thread and initialize the SDK on that thread.
</Info>

<CodeGroup>
  ```Java Java theme={null}
  import com.moengage.cordova.MoEInitializer;
  import com.moengage.core.MoEngage;
  import com.moengage.core.DataCenter;

  // this is the instance of the application class and "YOUR_Workspace_ID" is the Workspace ID from the dashboard.
  MoEngage.Builder moEngage = new MoEngage.Builder(this,"YOUR_Workspace_ID”, DataCenter.DATA_CENTER_X);
  MoEInitializer.initialiseDefaultInstance(this, moEngage);
  ```
</CodeGroup>

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

| Data Center                | Dashboard host            |
| -------------------------- | ------------------------- |
| DataCenter.DATA\_CENTER\_1 | dashboard-01.moengage.com |
| DataCenter.DATA\_CENTER\_2 | dashboard-02.moengage.com |
| DataCenter.DATA\_CENTER\_3 | dashboard-03.moengage.com |
| DataCenter.DATA\_CENTER\_4 | dashboard-04.moengage.com |
| DataCenter.DATA\_CENTER\_5 | dashboard-05.moengage.com |

In case your application does not have an Application class yet navigate to 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.\
Refer to the [API reference doc](https://moengage.github.io/android-api-reference/core/com.moengage.core/-mo-engage/-builder/index.html) for a detailed list of possible configurations.

# 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](https://developer.android.com/guide/topics/data/autobackup). 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](/developer-guide/android-sdk/sdk-integration/basic-integration/exclude-mo-engage-storage-file-from-auto-backup) section of the documentation to learn more about which files to exclude.
