Android活動未找到廣播接收器

Question

您好，我試圖設置基於輸入到SQL數據庫的通知。當我嘗試保存輸入的數據時，出現錯誤AlarmReciever Activity Not Found;

當我在下面添加到清單，我收到了類似的錯誤無法找到明確的類我本來這個清單中的

<receiver android:process=":remote" android:name="AlarmReciever"></receiver> 

。任何建議將不勝感激。

<activity 
      android:name=".AlamReciever" 
      android:label="@string/title_activity_user_menu" > 

     </activity> 

Addcourse類片斷

       String moduleStartMinute = timePickerStart.getCurrentMinute().toString(); 

       String moduleEndHour = timePickerEnd.getCurrentHour().toString(); 
       String moduleEndMinute = timePickerEnd.getCurrentMinute().toString(); 

       String moduleLocation = sqlModuleLocation.getText().toString();

        PendingIntent sender = PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT); 

        // Get the AlarmManager service 
        AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE); 
        am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), sender); 
        long weekly = AlarmManager.INTERVAL_DAY * 7; 
       am.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),weekly,sender); 
       startActivity(intent); 

AlarmReciever類

public class AlarmReciever extends BroadcastReceiver { 

@Override 

    public void onReceive(Context context, Intent intent) {  
     NotificationCompat.Builder nb = new NotificationCompat.Builder(context); 
     nb.setContentTitle("title"); 
     nb.setContentText("message"); 
     nb.setSmallIcon(R.drawable.ic_launcher); 

     NotificationManager nm = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE); 
     final Intent notificationIntent = new Intent(context, AddCourse.class); 
     notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK); 

     final PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0); 
     nb.setContentIntent(contentIntent); 
     Notification notification = nb.getNotification(); 
     nm.notify(0, notification); 
     }

Answer 1

如果您使用的是廣播接收器，它應被宣佈爲一個接收器，不是一個活動和噓通常應該有一個相關的行動。事情是這樣的：

<receiver android:name=".myReceiverName" android:exported="true"> 
<intent-filter> 
    <action android:name="android.intent.action.some_action"/> 
    <data android:scheme="package" android:path="com.blah.mypackage"> 
</intent-filter> 

見詳細說明，官方指導：

https://developer.android.com/guide/topics/manifest/receiver-element.html

Answer 2

您在AndroidManifest.xml文件同一封裝內登記Activity和BroadcastReceiver具有相同名稱的所以用活動名稱，而不是用於註冊活動的BroadcastReceiver類

 <activity 
      android:name=".Your_Activity_Name" 
      android:label="@string/title_activity_user_menu" > 
     </activity> 

Answer 3

試試這並保持接收者的名稱與活動不同。

<activity 
     android:name="com.example.mycoursetimetable.AlarmReciever" 
     android:label="@string/title_activity_user_menu" > 

    </activity>
