Android App and MySqlConnection: Resolving 'connection.open' Error

When attempting to establish a database connection using MySqlConnection in an Android app, you might encounter the following error:

System.TypeInitializationException: The type initializer for 'MySql.Data.MySqlClient.Replication.ReplicationManager' threw an exception.

To resolve this issue, consider the following solution:

Replace MySql.Data with MySqlConnector

Instead of using the MySql.Data package, opt for the MySqlConnector package from NuGet. This package is designed specifically for Xamarin Android and addresses the connection error.

Updated Code:

<code class="csharp">using MySqlConnector;

public void Conectar()
{
    // Initialize MySQL .NET connector
    MySqlConnection.Initialize();

    string SC;

    SC = "server = XXX; Port = 3306; database = XXX; user id = XXX; password = XXX; charset = utf8";

    _Conn = new MySqlConnection(SC);

    _Conn.Open();
}</code>

Additional Considerations:

  • Ensure that the MySqlConnector package is added to your project's references through NuGet.
  • Confirm that the connection string (SC) contains correct database settings.

Conclusion:

By switching from MySql.Data to MySqlConnector, you can establish database connections successfully in Android apps and avoid the 'connection.open' error.
