(Android™) Get the LastErrorText for an Asynchronous Method CallSee more Async ExamplesDemonstrates how to get the LastErrorText information for a Chilkat method called asynchronously.
// 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. CkSocket socket = new CkSocket(); // The Async call simply creates the task. The "Connect" method has not yet been called. int maxWaitMs = 5000; // Let's intentionally cause this connect to fail by giving it an invalid domain.. CkTask task = socket.ConnectAsync("amazonbladflakjsdflksadjf.com",443,true,maxWaitMs); if (socket.get_LastMethodSuccess() == false) { Log.i(TAG, socket.lastErrorText()); return; } // Start the background thread to run the task. boolean success = task.Run(); if (!success) { Log.i(TAG, task.lastErrorText()); return; } // The application is now free to do anything else // For this example, we'll simply sleep and periodically // check to see if the Socket Connect if finished. while (task.get_Finished() != true) { // Sleep 1 ms. task.SleepMs(1); } // If the task completed, it means the method (in this case the Connect method) was called and returned success or failure. if (task.get_StatusInt() != 7) { Log.i(TAG, "Task did not complete."); Log.i(TAG, "task status: " + task.status()); return; } // Get the success/failure of the Connect // (This is the return value of the Connect method had it been called synchronously) success = task.GetResultBool(); if (success == false) { // Get the LastErrorText for the Connect method call. // Had we called Connect synchronously, we would've simply accessed the socket object's LastErrorText property. // Instead, we get the task object's ResultErrorText. Log.i(TAG, task.resultErrorText()); } else { Log.i(TAG, "Connect succeeded."); } } static { System.loadLibrary("chilkat"); // Note: If the incorrect library name is passed to System.loadLibrary, // then you will see the following error message at application startup: //"The application <your-application-name> has stopped unexpectedly. Please try again." } } |
