Question

我正在尝试构建一个使用SmsMessage类的应用程序，但有两个版本，具体取决于设备的API级别：

android.telephony.gsm.SmsMessage（已弃用1.6及以上）

android.telephony.SmsMessage（1.6及以上的新类）

我想要定位1.5，然后在1.6或更高版本的设备上运行较新的类（android.telephony.SmsMessage）。我该怎么做？

我已经厌倦了这个：http://devtcg.blogspot.com/2009/12/gracefully-supporting-multiple-android.html但我无法让它工作（作者没有提到他/她如何处理不同的导入，确切的api级别设置等。）

感谢。

Answer 1

您需要定位android-4或更高版本，否则新版本将不存在。

关于加载正确的版本，您可以使用条件类加载，在this sample project中演示两个版本的联系人内容提供商。此外，this article是Google在此主题上所说的话。

使用CommonsWare的例子，我能够创建它（有效）：

[清单设置]

1.将目标SDK设置为4（或更高）（Android 1.6 +）

2.将min SDK设置为3（Android 1.5）

[OfflineSMSReceiver.java]

import java.util.Date;
import com.apps.myapp.Utilities;
import com.apps.myapp.SmsMessageBridge;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;

public class OfflineSMSReceiver extends SMSReceiver
{
    @Override
    public void onReceive(Context context, Intent intent)
    {
        System.out.println("SMS_RECEIVED");

        System.out.println(Utilities.getNow());
        //---get the SMS message passed in---
        Bundle bundle = intent.getExtras();        
        SmsMessageBridge[] msgs = null;

        Date date; 
        long timeStamp;
        String time;
        String str = "";            
        if (bundle != null)
        {
            //---retrieve the SMS message received---
            Object[] pdus = (Object[]) bundle.get("pdus");
            msgs = new SmsMessageBridge[pdus.length];           
            for (int i=0; i<msgs.length; i++){
                msgs[i] = SmsMessageBridge.INSTANCE.createFromPdu((byte[])pdus[i]);
                timeStamp = msgs[i].getTimestampMillis();
                date = new Date(timeStamp);
                time = this.getTime(date.getHours(),date.getMinutes(),date.getSeconds());
                str += "SMS from " + msgs[i].getOriginatingAddress();                     
                str += " :";
                str += msgs[i].getMessageBody().toString();
                str += "\n";
                str += "TIME: "+time+"\t"+this.getNowDate();
            }

            System.out.println(str);
        }
    }
}

[SmsMessageBridge.java]

import android.os.Build;

public abstract class SmsMessageBridge
{
    public abstract SmsMessageBridge createFromPdu(byte[] pdu);
    public abstract long getTimestampMillis();
    public abstract String getOriginatingAddress();
    public abstract String getMessageBody();

    public static final SmsMessageBridge INSTANCE = getBridge();

    private static SmsMessageBridge getBridge()
    {
        final int sdkVersion = new Integer(Build.VERSION.SDK).intValue();

        if(sdkVersion>3)
        {
            return new NewSmsMessage();
        }
        else
        {
            return new OldSmsMessage();
        }
    }
}

[OldSmsMessage.java]

import android.telephony.gsm.SmsMessage;//*NOTE* depreciated in v1.6+

@SuppressWarnings("deprecation")
public class OldSmsMessage extends SmsMessageBridge
{
    private SmsMessage myMSG;

    @Override
    public SmsMessageBridge createFromPdu(byte[] pdu)
    {
        myMSG = SmsMessage.createFromPdu(pdu);
        return this;
    }

    @Override
    public long getTimestampMillis()
    {
        return myMSG.getTimestampMillis();
    }

    @Override
    public String getOriginatingAddress()
    {
        return myMSG.getOriginatingAddress();
    }

    @Override
    public String getMessageBody()
    {
        System.out.println("v1.5");
        return myMSG.getMessageBody();
    }
}

[NewSmsMessage.java]

import android.telephony.SmsMessage;

public class NewSmsMessage extends SmsMessageBridge
{
    private SmsMessage myMSG;

    @Override
    public SmsMessageBridge createFromPdu(byte[] pdu)
    {
        myMSG = SmsMessage.createFromPdu(pdu);
        return this;
    }

    @Override
    public String getMessageBody()
    {
        //System.out.println("v1.6+");
        return myMSG.getMessageBody();
    }

    @Override
    public String getOriginatingAddress()
    {
        return myMSG.getOriginatingAddress();
    }

    @Override
    public long getTimestampMillis()
    {
        return myMSG.getTimestampMillis();
    }

}

再次感谢CommonsWare。

Android - 支持1.6+，并支持1.5中的弃用代码？
