從Android中的服務開始活動時出錯

我有一個收聽來電的接收器。從這個接收器我開始一個服務，將發送電子郵件（使用android意圖），但我得到一個例外（從日誌貓PLZ引用日誌）。從Android中的服務開始活動時出錯

了java.lang.RuntimeException：無法啓動服務 [email protected]意圖{ CMP = com.pack.android.email.service/com.pack.android。 service.EmailService }：android.util.AndroidRuntimeException：在Activity上下文之外調用的startActivity（）需要FLAG_ACTIVITY_NEW_TASK 標誌。這真的是你想要的嗎？

我已經設置了'FLAG_ACTIVITY_NEW_TASK'和'FLAG_FROM_BACKGROUND'。這不是用戶活動。我正嘗試使用intent.SENDTO/SEND啓動現有活動（發送電子郵件）。

奇怪的事情是錯誤：android.content.ActivityNotFoundException： 致無活動處理意向{行動= android.intent.action.SENDTO FLG = 0x10000004（有演員）}

我在這裏錯過了什麼？

使用Java Mail API發送電子郵件時，我面臨的另一個問題是郵件被正確發送，這看起來像是什麼，但不知何故郵件似乎永遠不會出現在郵箱中。我指的是下面的鏈接發送電子郵件沒有意圖： Send email without intent

這將是gr8，如果有人可以提供一些見解。

代碼如下：呼叫接收器： -

public class CallReceiver extends BroadcastReceiver 
{ 
    private static final String LOG_TAG = "CallReceiver"; 
    private static final String ACTION = "android.intent.action.PHONE_STATE"; 

    @Override 
    public void onReceive(Context context, Intent intent) 
    { 
     System.out.println("--------Inside onReceive of CallReceiver--------"); 
     Log.d(LOG_TAG, "Inside onReceive"); 

     if(intent.getAction().equals(ACTION)){ 
      Log.d(LOG_TAG, "-----Criteria matched-----"); 
      Intent emailIntent = new Intent(context, EmailService.class); 
      emailIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
      emailIntent.addFlags(Intent.FLAG_FROM_BACKGROUND); 
      context.startService(emailIntent); 
     } 
    } 
}

我的意圖中已經有了這些標誌。這不是用戶活動。我正嘗試使用意向INTENT.SENDTO啓動現有的活動。我注意到的奇怪的事情是錯誤：引起：android.content.ActivityNotFoundException：沒有找到處理Intent的活動{act = android.intent.action.SENDTO flg = 0x10000004（有額外）} – Adithya

從logcat發佈stacktrace 。同時發佈您用來啓動服務的代碼。也發佈代碼在服務的'onCreate（）' –

只是爲了添加..我試圖從模擬器發送電子郵件。我已成功使用意向從模擬器發送電子郵件。只是，當我從後臺使用java郵件API嘗試時，似乎沒有發生任何事情。 – Adithya

，你得到

android.content.ActivityNotFoundException: No Activity found to handle Intent { 
    act=android.intent.action.SENDTO flg=0x10000004 (has extras) }

的原因是因爲你從來沒有設置數據在意圖。 Android會嘗試查找可處理「SENDTO」操作和您提供的數據的活動。但是您沒有提供任何數據，因此無法找到合適的活動。你有這樣的代碼：

Intent emailIntent = new Intent(Intent.ACTION_SENDTO); 
emailIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
emailIntent.addFlags(Intent.FLAG_FROM_BACKGROUND); 
// emailIntent.setType("plain/text"); 
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, 
      new String[] { "[email protected]" }); 
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, 
      "Email from Intent"); 
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, 
      "Hi, This is 5554 from intent"); 
// getApplicationContext().startActivity(Intent.createChooser(emailIntent, "Send mail...")); 
Log.d(LOG_TAG, "context = " + getApplicationContext()); 
startActivity(emailIntent);

，但你需要調用emailIntent.setdataAndType()或emailIntent.setData()1 and emailIntent.setType（）`。

謝謝，但我從啓動器啓動電子郵件活動時並未使用setData。那次我能夠成功發送郵件。無論如何，我想從背景發送電子郵件，但一直沒有能夠這樣做！任何幫助將是偉大的 – Adithya

從您發佈的日誌，它看起來像電子郵件發送和接受。它是否着陸在垃圾郵件文件夾中？您可以嘗試將電子郵件發送到其他服務，並查看是否有效。 –

嘿..我總是收到郵件..它不是在垃圾郵件，但是它是在一些其他文件夾，因爲我的過濾器:) ..感謝很多。 – Adithya

看這個行中登錄：

android.util.AndroidRuntimeException：從外部一個活動的上下文中調用startActivity（）需要FLAG_ACTIVITY_NEW_TASK 標誌。這真的是你想要的嗎？

其中明確指出您需要FLAG_ACTIVITY_NEW_TASK才能從Service啓動Activity。所以加

intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
intent.addFlags(Intent.FLAG_FROM_BACKGROUND);

啓動活動從服務

我在我的代碼中有這些標誌。 – Adithya

使用FLAG_ACTIVITY_NEW_TASK

Intent myIntent = new Intent(getBaseContext(), myActivity.class); 
myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK|Intent.FLAG_FROM_BACKGROUND); 
getApplication().startActivity(myIntent);

從Android中的服務開始活動時出錯
