私はAndroidでSMSアプリに取り組んでおり、送信者が入力して[メッセージの送信]をクリックすると、メッセージはクラスEccで操作され、受信者に送信されます。受信者はこのメッセージを読み取ってEccクラスに送信する必要があり、そこで操作が行われ、送信者に返送されます。受信者にメッセージを送信することはできますが、受信者側では何も起こりません。

これがSmsReceiverクラスです

 package com.example.smsTest;

 import android.content.BroadcastReceiver;
 import android.content.Context;
 import android.content.Intent;
 import android.os.Bundle;
 import android.telephony.SmsMessage;
 import android.widget.Toast;

 public class SMSReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    // TODO Auto-generated method stub
    Bundle bundle=intent.getExtras();
    Object[] messages=(Object[])bundle.get("pdus");
    SmsMessage[] sms=new SmsMessage[messages.length];

    Ecc ecc;
    ecc = new Ecc(context);
    String msg_receive = intent.getStringExtra("message1"); 
    if (msg_receive != null)  { 

    for(int n=0;n<messages.length;n++)
        {
            sms[n]=SmsMessage.createFromPdu((byte[]) messages[n]);

        }

    for(SmsMessage msg:sms)
        {
            String ph=msg.getDisplayOriginatingAddress();
            String body=msg.getMessageBody();
            ecc.recv(ph,body);          
            Toast.makeText(context,"ecc entered at receiver", Toast.LENGTH_SHORT).show();

            SMSTest.update("\n From:" +ph+"\n"+"message:"+body+"\n");

            Toast.makeText(context,"updated", 
                    Toast.LENGTH_SHORT).show();

        }

    }
  } 
}

これがeccクラスです

こちらがSMSTestクラスです

package com.example.smsTest;

}

public static void update(String msg) {

    txtmsg.append(msg);

}

}

これがマニフェストファイルです

エラーは発生しません。送信者側は、受信者がメッセージを受信するように機能しますが、何も起こりません。

Eccクラスのように：

// Constructor
public Ecc(SMSTest smsTest) {   //<<<<
    this.smsTest = smsTest;
}

アクティビティタイプパラメータを使用してEccコンストラクタを作成しましたが、オブジェクトの作成時にuがに渡されます。SMSTestSMSReceiverBroadcastReceiver

解決：

Activityインスタンスを作成してActivityのメソッドを呼び出す代わりに、Activityまたは。の間でメソッドを共有するための別個の通常のJavaクラスを作成しますBroadcastReceiver。コンポーネントインスタンスを渡す代わりに、SMSを送信するためのコンテキストを渡します。

Context context ;
    // Constructor
    public Ecc(Context context) {   //<<<<
        this.context = context;
    }

contextSMSの送信に 使用し、Eccクラスインスタンスを次のように作成しますBroadcastReceiver。

Ecc ecc;
ecc=new Ecc(context);  //<< pass context instead of this

このようにManifastファイルに放送を登録してください

<receiver android:name="your package name and class name">  </receiver>

または、このようなマニフェストではなく、コードでブロードキャストを登録してみてください

IntentFilter in_filter = new IntentFilter("android.intent.action.PHONE_STATE");
     Incoming = new BroadcastReceiver()
            {   
            @Override
            public void onReceive(final Context context, Intent intent) {
                // TODO Auto-generated method stub
                  {
                      telephonyManager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
                      callEventListener = new PhoneStateListener(){
                          public void onCallStateChanged(int state, String incomingNumber) {
                                super.onCallStateChanged(state, incomingNumber);
                                if (state == TelephonyManager.CALL_STATE_IDLE){
                                     System.out.println("Idel State phone");
                                }
                                else if (state == TelephonyManager.CALL_STATE_RINGING){
                                    context.stopService(new Intent(context, myPlayService.class));
                                    System.out.println("phone ringing");
                                }
                            }
                        };
                telephonyManager.listen(callEventListener, PhoneStateListener.LISTEN_CALL_STATE);
                      }
                 }
            };

            this.registerReceiver(Incoming, in_filter);
