public class SimpleActivity extends Activity {

  private static final String TAG = "Chilkat";

  // Called when the activity is first created.
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    CkCert cert = new CkCert();

    // The certificate must originate from a source where the private key material is available to be included
    // in the upload to Azure Key Vault.

    boolean success = cert.LoadPfxFile("qa_data/pfx/myCert.pfx","pfx_password");
    if (success == false) {
        Log.i(TAG, cert.lastErrorText());

    CkJsonObject json = new CkJsonObject();

    // Indicate this request is to upload to Azure Key Vault.
    json.UpdateString("service","azure-keyvault");

    // Provide your OAuth2 client credentials for your Azure App (service principal) that has
    // the required Role-Based Access Control (RBAC) permissions.
    json.UpdateString("auth.client_id","APP_ID");
    json.UpdateString("auth.client_secret","APP_PASSWORD");
    json.UpdateString("auth.tenant_id","TENANT_ID");

    // Indicate the key vault name
    json.UpdateString("vault_name","VAULT_NAME");

    // When you import a certificate into an Azure Key Vault, the certificate name and vault name are included as 
    // parts of the URL to specify the target location where the certificate should be stored. 
    // The URL follows a specific format to identify the target Key Vault and the certificate within it. 
    // Here's how the certificate name and vault name are incorporated into the URL:
    // https://VAULT_NAME.vault.azure.net//certificates/CERT_NAME/import?api-version=7.4

    // Specify an arbitrary certificate name, but one that can be used in a URL as shown above.  (i.e. alphanumeric with no SPACE chars)
    json.UpdateString("cert_name","CERT_NAME");

    // Add optional tags if desired. Tags can be anything you want.   
    json.UpdateString("tags.serial",cert.serialNumber());
    json.UpdateString("tags.issuer",cert.issuerCN());
    json.UpdateString("tags.subject",cert.subjectCN());

    // OK.. everything is specified.  Simply call UploadToCloud.
    CkJsonObject jsonOut = new CkJsonObject();
    jsonOut.put_EmitCompact(false);
    success = cert.UploadToCloud(json,jsonOut);
    if (success == false) {
        Log.i(TAG, cert.lastErrorText());
        Log.i(TAG, jsonOut.emit());
        return;
        }

    // Success!  Go to the Azure portal and refresh to see the certificate has been uploaded.
    // The jsonOut provides the JSON response from the Azure server.
    Log.i(TAG, jsonOut.emit());
    Log.i(TAG, "Success");
