(Android™) Get an Azure AD Access TokenDemonstrates how to obtain an Azure AD access token for authentication using a client ID, client secret, and tenant ID.
// Important: Don't forget to include the call to System.loadLibrary // as shown at the bottom of this code sample. package com.test; import android.app.Activity; import com.chilkatsoft.*; import android.widget.TextView; import android.os.Bundle; 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); // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code.
