我是新來的Android ..我試圖編寫安卓服務，它將在設備啓動時啓動。當我用模擬器運行應用程序時，我能夠在「adb logcat」中看到我的調試語句（system.outs）;這意味着我的服務在啓動完成時被調用。但是根據日誌，'onStart'服務方法中的整個代碼沒有得到執行。日誌不顯示所有預期的system.outs。安卓服務啓動時開機得到強制停止
下面出現 '力停止服務' 語句日誌（標記爲粗體）： -

下面是我的代碼
AndroidManifest.xml中
<?xml version="1.0" encoding="utf-8"?>

System.out.println("**************Service started****************");
Toast.makeText(this, "Service Started", Toast.LENGTH_LONG).show();
int cnt=0;
while (true)
{
Calendar currentDate = Calendar.getInstance();
SimpleDateFormat formatter=new SimpleDateFormat("yyyy/MMM/dd HH:mm:ss");
String dateNow = formatter.format(currentDate.getTime());
System.out.println("*********Current date is :=> " + dateNow);
cnt++;
try{
Thread.sleep (20000);
}catch (Exception e){System.out.println(e);}
if (cnt == 4)
break;
}
System.out.println("********CNT************* " + cnt);
}
}
package com.webapps.service;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class MyStartupIntentReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
Intent serviceIntent = new Intent();
serviceIntent.setAction("com.wissen.startatboot.SimpleService");
System.out.println("**************MyStartupIntentReceiver****************");
context.startService(serviceIntent);
}
}
SimpleService.java下包com.webapps.service定義;而MyStartupIntentReceiver將intentAction設置爲com.wissen.startatboot.SimpleService。
這是否導致我的服務強制停止？
