大家好，我有非常重要的问题，请帮助我。我正在尝试使用广播接收器处理传入的消息。但是，它不起作用。我发送下面的代码请帮助我。

                            }
                            else if(body.startsWith("<secureSmsMessaging>")){
                            createMessage(messages[0]);
                            }
                            messages[0].getMessageBody().replaceAll(body, decrypted);


                        }
                    }
                }

                this.abortBroadcast();
           }
}

我试图调试它。但它没有进入我的广播接收器。每当我发送消息时，Android的默认消息服务都会处理它。我做错了什么？

我在等你的回答。谢谢。

我猜你错了@ onReceive 方法。

我创建了一个小应用程序来使用广播接收器收听传入的消息。

SMSBroadcastReceiver.java

public class SMSBroadcastReceiver extends BroadcastReceiver{

@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 Phone No: " +msgs[i].getOriginatingAddress();
            str +="\n"+"Message is: ";
            str += msgs[i].getMessageBody().toString();
            str +="\n";
        }

        Log.v("Debug", str);
        Toast.makeText(context, str, Toast.LENGTH_SHORT).show();
    }
}}

AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.rdc"
  android:versionCode="1"
  android:versionName="1.0">
<uses-sdk android:minSdkVersion="8" />

<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>
<uses-permission android:name="android.permission.READ_SMS"></uses-permission>

<application android:icon="@drawable/icon" android:label="@string/app_name">
    <receiver android:name=".SMSBroadcastReceiver">
        <intent-filter>
            <action android:name="android.provider.Telephony.SMS_RECEIVED"/>
        </intent-filter>
    </receiver>

</application></manifest>

您可以检查这一点并实施到您的代码中！

我通过使用 https 服务器解决了我的问题。我的问题是在发送用户的公钥和加密消息期间将包含字节数组的字符串转换为字节数组。现在我正在使用 https 服务器来编写我的员工，然后从那里。现在更经济了。我建议每个想要在消息传递中提供加密的人使用https服务器，因为您可能会遇到很多问题。
