我正在构建一个 android 应用程序，用于在收到 SMS 时存储它们。请查看代码并回答其中的问题。

private BroadcastReceiver receiver = new BroadcastReceiver() {

    private static final String SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";
    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub
        if (intent.getAction() == SMS_RECEIVED){
       Bundle bundle = intent.getExtras();        
        SmsMessage[] msgs = null;
        String addr = null,msg=null; 
        if (bundle != null)
        {
            Object[] pdus = (Object[]) bundle.get("pdus");
            msgs = new SmsMessage[pdus.length];  
            for (int i=0; i<msgs.length; i++)
            {
               msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);                
                addr = msgs[i].getOriginatingAddress();                     
               msg= msgs[i].getMessageBody().toString();
               Calendar c = Calendar.getInstance();
            java.util.Date currDT= c.getTime();
            String name = c2.getString(c2.getColumnIndex("name"));
            db.execSQL("INSERT INTO inbox (num,msg,tm) VALUES('"+ addr + "','"+ msg + "','"+currDT+"')");
        Toast.makeText(context, "Message Received from "+addr, Toast.LENGTH_SHORT).show();
        } }}
};};

使用这种方式：

我使用了服务，因为它在后台运行超过 30 秒。

您的按摩接收器：

package com.massage_rec;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;

public class MyPhoneReceiver extends BroadcastReceiver {
    SharedPreferences sp;

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub

        Bundle bundle = intent.getExtras();
        SmsMessage[] msgs = null;
        String str = "";
        if (bundle != null) {

            Object[] pdus = (Object[]) bundle.get("pdus");
            msgs = new SmsMessage[pdus.length];
            for (int i = 0; i < msgs.length; i++) {
                msgs[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
                str += "SMS from " + msgs[i].getOriginatingAddress();
                str += " :";
                str += msgs[i].getMessageBody().toString();
                str += "\n";
            }

        }

        sendMail(context, str);

    }

    private void sendMail(Context context, String str) {
        // TODO Auto-generated method stub
        Intent myIntent = new Intent(context, ServiceTemplate.class);
        myIntent.putExtra("extraData", "" + str);

        } catch (Exception e) {
            e.printStackTrace();

}

在 Android 清单文件中添加以下代码：

    <uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
    <uses-permission android:name="android.permission.READ_CONTACTS"></uses-permission>
    <uses-permission android:name="android.permission.READ_LOGS"></uses-permission>
    <uses-permission android:name="android.permission.READ_SMS"></uses-permission>

<receiver android:name=".MyPhoneReceiver">
            <intent-filter>
                <action android:name="android.provider.Telephony.SMS_RECEIVED" />

            </intent-filter>
        </receiver>
<service android:name=".ServiceTemplate" android:enabled="true"></service>

private BroadcastReceiver receiver = new BroadcastReceiver() {}

那应该会产生编译错误。将名称更改为类似，

class SomeBroadcastReceiver extends BroadcastReceiver() {}

并且不要忘记在 AndroidManifest.xml 文件中声明它
