構造函數通知已棄用

Question

我對android應用程序開發非常陌生。在這麼多教程的幫助下，我創建了一個帶有webview，actionbar和GCM的應用程序。一切正常。但我收到警告「構造函數通知已被棄用」。我已經通過notification.builder。但我無法用新的通知buider修改我的代碼。有人可以幫助我.....

public class GCMIntentService extends GCMBaseIntentService { 

private static final String TAG = "GCMIntentService"; 

public GCMIntentService() { 
    super(SENDER_ID); 
} 

/** 
* Method called on device registered 
**/ 
@Override 
protected void onRegistered(Context context, String registrationId) { 
    Log.i(TAG, "Device registered: regId = " + registrationId); 
    displayMessage(context, "Your device registred with GCM"); 
    Log.d("NAME"," "+ MainActivity.name); 
    ServerUtilities.register(context, MainActivity.name, MainActivity.email, MainActivity.AndroidVersion, MainActivity.AndroidID, MainActivity.manufacturer, MainActivity.model, registrationId); 
} 

/** 
* Method called on device un registred 
* */ 
@Override 
protected void onUnregistered(Context context, String registrationId) { 
    Log.i(TAG, "Device unregistered"); 
    displayMessage(context, getString(R.string.gcm_unregistered)); 
    ServerUtilities.unregister(context, registrationId); 
} 

/** 
* Method called on Receiving a new message 
* */ 
@Override 
protected void onMessage(Context context, Intent intent) { 
    Log.i(TAG, "Received message"); 
    String message = intent.getExtras().getString("price"); 

    displayMessage(context, message); 
    // notifies user 
    generateNotification(context, message); 
} 

/** 
* Method called on receiving a deleted message 
* */ 
@Override 
protected void onDeletedMessages(Context context, int total) { 
    Log.i(TAG, "Received deleted messages notification"); 
    String message = getString(R.string.gcm_deleted, total); 
    displayMessage(context, message); 
    // notifies user 
    generateNotification(context, message); 
} 

/** 
* Method called on Error 
* */ 
@Override 
public void onError(Context context, String errorId) { 
    Log.i(TAG, "Received error: " + errorId); 
    displayMessage(context, getString(R.string.gcm_error, errorId)); 
} 

@Override 
protected boolean onRecoverableError(Context context, String errorId) { 
    // log message 
    Log.i(TAG, "Received recoverable error: " + errorId); 
    displayMessage(context, getString(R.string.gcm_recoverable_error, 
      errorId)); 
    return super.onRecoverableError(context, errorId); 
} 

/** 
* Issues a notification to inform the user that server has sent a message. 
*/ 
private static void generateNotification(Context context, String message) { 
    int icon = R.drawable.ic_launcher; 
    long when = System.currentTimeMillis(); 
    NotificationManager notificationManager = (NotificationManager) 
      context.getSystemService(Context.NOTIFICATION_SERVICE); 
    Notification notification = new Notification(icon, message, when); 

    String title = context.getString(R.string.app_name); 

    Intent notificationIntent = new Intent(context, MainActivity.class); 
    // set intent so it does not start a new activity 
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | 
      Intent.FLAG_ACTIVITY_SINGLE_TOP); 
    PendingIntent intent = 
      PendingIntent.getActivity(context, 0, notificationIntent, 0); 
    notification.setLatestEventInfo(context, title, message, intent); 
    notification.flags |= Notification.FLAG_AUTO_CANCEL; 

    // Play default notification sound 
    notification.defaults |= Notification.DEFAULT_SOUND; 

    //notification.sound = Uri.parse("android.resource://" + context.getPackageName() + "your_sound_file_name.mp3"); 

    // Vibrate if vibrate is enabled 
    notification.defaults |= Notification.DEFAULT_VIBRATE; 
    notificationManager.notify(0, notification);  

} 

}

你試圖使用的構造被棄用API 11的含義它不是通知不再支持，不應該使用。使用Notification.Builder代替https://developer.android.com/reference/android/app/Notification.Builder.html

Notification noti = new Notification.Builder(mContext) 
    .setContentTitle("New mail from " + sender.toString()) 
    .setContentText(subject) 
    .setSmallIcon(R.drawable.new_mail) 
    .setLargeIcon(aBitmap) 
    .build(); 

您目前有以下幾種：

Notification notification = new Notification(icon, message, when); 

此構造有利於Notification.Builder的淘汰，看起來像下面這樣：

Notification notification = new Notification.Builder(context) 
    .setContentText(message) 
    .setSmallIcon(icon) 
    .setWhen(when) 
    .build();

至於原始問題，如果您的系統支持GCMBaseIntentService，則此類可以正常工作：

package ...; 

import android.app.Notification; 
import android.app.NotificationManager; 
import android.app.PendingIntent; 
import android.content.Context; 
import android.content.Intent; 
import android.util.Log; 

import com.google.android.gcm.GCMBaseIntentService; 

import static com.example.taxiprofessional.CommonUtilities.SENDER_ID; 
import static com.example.taxiprofessional.CommonUtilities.displayMessage; 

public class GCMIntentService extends GCMBaseIntentService { 

    private static final String TAG = "GCMIntentService"; 

public GCMIntentService() { 
    super(SENDER_ID); 
} 

/** 
    * Method called on device registered 
    **/ 
@Override 
protected void onRegistered(Context context, String registrationId) { 
    Log.i(TAG, "Device registered: regId = " + registrationId); 
    displayMessage(context, "Your device registred with GCM"); 
    AccountInformation info=AccountInformation.sharedInstance(); 
    ServerUtilities.register(context, info.email, info.password, registrationId); 
} 

/** 
    * Method called on device un registred 
    * */ 
@Override 
protected void onUnregistered(Context context, String registrationId) { 
    Log.i(TAG, "Device unregistered"); 
    displayMessage(context, getString(R.string.gcm_unregistered)); 
    ServerUtilities.unregister(context, registrationId); 
} 

/** 
    * Method called on Receiving a new message 
    * */ 
@Override 
protected void onMessage(Context context, Intent intent) { 
    Log.i(TAG, "Received message"); 
    String message = intent.getExtras().getString("price"); 

    displayMessage(context, message); 
    // notifies user 
    generateNotification(context, message); 
} 

/** 
    * Method called on receiving a deleted message 
    * */ 
@Override 
protected void onDeletedMessages(Context context, int total) { 
    Log.i(TAG, "Received deleted messages notification"); 
    String message = getString(R.string.gcm_deleted, total); 
    displayMessage(context, message); 
    // notifies user 
    generateNotification(context, message); 
} 

/** 
    * Method called on Error 
    * */ 
@Override 
public void onError(Context context, String errorId) { 
    Log.i(TAG, "Received error: " + errorId); 
    displayMessage(context, getString(R.string.gcm_error, errorId)); 
} 

@Override 
protected boolean onRecoverableError(Context context, String errorId) { 
    // log message 
    Log.i(TAG, "Received recoverable error: " + errorId); 
    displayMessage(context, getString(R.string.gcm_recoverable_error, 
      errorId)); 
    return super.onRecoverableError(context, errorId); 
} 

/** 
    * Issues a notification to inform the user that server has sent a message. 
    */ 
private static void generateNotification(Context context, String message) { 
    int icon = R.drawable.taxi_profi; 
    long when = System.currentTimeMillis(); 
    NotificationManager notificationManager = (NotificationManager) 
      context.getSystemService(Context.NOTIFICATION_SERVICE); 
    Notification notification = new Notification(icon, message, when); 

    String title = context.getString(R.string.app_name); 

    Intent notificationIntent = new Intent(context, Dashboard.class); 
    // set intent so it does not start a new activity 
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | 
      Intent.FLAG_ACTIVITY_SINGLE_TOP); 
    PendingIntent intent = 
      PendingIntent.getActivity(context, 0, notificationIntent, 0); 
    notification.setLatestEventInfo(context, title, message, intent); 
    notification.flags |= Notification.FLAG_AUTO_CANCEL; 

    // Play default notification sound 
    notification.defaults |= Notification.DEFAULT_SOUND; 

    // Vibrate if vibrate is enabled 
    notification.defaults |= Notification.DEFAULT_VIBRATE; 
    notificationManager.notify(0, notification);  

} 

}

我嘗試下面的教程在： http://javapapers.com/android/google-cloud-messaging-gcm-for-android-and-push-notifications/ 事實上，我似乎能夠註冊和通知的發送給任何錯誤，因爲你可能在看到： http://push.taxiprofessional.net/android/testNotification.php

然而，沒有通知到達。有沒有人使用過，可能有助於揭穿它？
