二、CallAlarm中的代码：

package com.cn.daming;

import android.content.Context;

import android.content.Intent;

import android.content.BroadcastReceiver;

import android.os.Bundle;

public class CallAlarm extends BroadcastReceiver

{

@Override

public void onReceive(Context context, Intent intent)

{

Intent i = new Intent(context, AlarmAlert.class);

Bundle bundleRet = new Bundle();

bundleRet.putString("STR_CALLER", "");

i.putExtras(bundleRet);

i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

context.startActivity(i);

}

}
