發送超過100條短信時Android應用程序強制關閉

Question

我試圖發送文本消息一定的時間，當我執行超過100次的任何操作時它會強制關閉應用程序。有什麼建議麼？

好的，這裏是我更新的代碼，現在有一些額外的問題 - 敬酒永遠不會消失，如果我啓用我的if語句進行數據驗證，它將無法正常工作（基本上試圖提示用戶輸入信息，如果它爲空，而不是隻強制關閉應用程序）

這裏是我更新的代碼：

package net.learn2develop.SMS; 

import android.app.Activity; 
import android.app.PendingIntent; 
import android.content.BroadcastReceiver;

EditText PhNumber, Message, TxtCount; 
Button btnSendSMS; 

/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    //create text box to enter phone number 
    PhNumber=(EditText) findViewById(R.id.PhNumber); 

    //create text box to enter message 
    Message=(EditText) findViewById(R.id.Message); 

    //create text box to see how many times the user wants to send message 
    TxtCount=(EditText) findViewById(R.id.TxtCount); 

    //create button to send text message 
    btnSendSMS = (Button) findViewById(R.id.btnSendSMS); 
    //create listener for button 
    btnSendSMS.setOnClickListener(new View.OnClickListener() 

    {    
     public void onClick(View v) 
      {   
       //variable for count. 
       int count = 1;

Answer 1

也許嘗試分裂的消息，或送他們一個計時器，而不是一個循環，你可以嘗試一些像這樣：

   Thread background = new Thread (new Runnable() { 
       public void run() { 
        Thread.sleep(100); 
          // Send message 
       } 
      }); 

Answer 2

您可能應該安排服務在每條消息發送（或失敗）時發送廣播，然後才發送下一條消息。您可能正在淹沒服務，導致部隊關閉。

檢查the docs關於如何使用「發送的意圖」。
