我一直在試圖創建一個鬧鐘管理器，讓我發送一個小時的電子郵件。我的應用程序是一種日曆，所以我會有很多任務，我需要區分程序。爲此，我使用事件的開始時間作爲id。Android無法啓動意圖BroadcastReceiver
這是我的代碼：
public class EndEventTask extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
String email = "[email protected]";
Uri uri = Uri.parse(email);
Intent EmailActivity = new Intent(Intent.ACTION_SENDTO, uri);
//EmailActivity.putExtra(Intent.EXTRA_SUBJECT,
// "Customer comments/questions");
String message="Prueba de la aplicación del proyecto.";// message to send
EmailActivity.putExtra(Intent.EXTRA_TEXT, message);
EmailActivity.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(EmailActivity);
}
}
，報警管理器從，一旦任務被髮送，活動將完成一個活動發送。此處作爲一例::
if(preferences.getBoolean("AlertCustomer", false)){
scheduleAlarmEnd(finalDate.getTimeInMillis());
}
Intent newIntent = getIntent();
newIntent.putExtra("title", dateTitleText);
newIntent.putExtra("beginDate", selectedDate.getTimeInMillis());
newIntent.putExtra("endDate", finalDate.getTimeInMillis());
newIntent.putExtra("siteLatBeg", latBeg);
newIntent.putExtra("siteLonBeg", lonBeg);
newIntent.putExtra("siteBegText", siteBegTextAutoComp);
newIntent.putExtra("siteLatDes", latDes);
newIntent.putExtra("siteLonDes", lonDes);
newIntent.putExtra("siteDesText", siteText);
newIntent.putExtra("mobile", mobileInt);
newIntent.putExtra("email", emailText);
newIntent.putExtra("duration", duration + extraTime);
this.setResult(RESULT_OK, newIntent);
finish();
...............
private void scheduleAlarmEnd(long time)
{
Intent intentAlarm = new Intent(this, EndEventTask.class);
// create the object
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
PendingIntent pIntent = PendingIntent.getBroadcast(this,
(int) time, intentAlarm, PendingIntent.FLAG_UPDATE_CURRENT);
//set the alarm for particular time
alarmManager.set(AlarmManager.RTC_WAKEUP,time, pIntent);
}
這是我Mainfest：
<uses-permission android:name="com.android.alarm.permission.SET_ALARM"/>
.. .....................
<receiver android:name="com.android.task.BegEventTask">
<intent-filter>
<action android:name="android.intent.action.ACTION_SENDTO" />
</intent-filter>
</receiver>
最後我得到一個錯誤，當開始È意圖（context.startActivity（EmailActivity））：
