海每个人实际上都在尝试创建一个应用程序，该应用程序支持基于 SIP 在互联网上进行音频呼叫，这里使用的是本地 sip，我遇到了来电问题，我已经完成了服务的注册部分，但是在接听电话时，我无法接听电话，请帮帮我

在这里，我附上了我的广播接收器文件广播接收器文件

package example.com.myapplication;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.net.sip.SipAudioCall;
import android.net.sip.SipException;
import android.net.sip.SipProfile;
import android.util.Log;

public class IncomingReceiver extends BroadcastReceiver {
public  SipAudioCall incomingCall=null;
@Override
public void onReceive(Context context, Intent intent) {

    try {
        SipAudioCall.Listener listener = new SipAudioCall.Listener() {
            @Override
            public void onRinging(SipAudioCall call, SipProfile caller) {
                try {
                    call.answerCall(30);
                    Log.d("Incoming", call.toString());
                    Log.d("Name",call.getPeerProfile().getProfileName());
                } catch (Exception e) {
                    e.printStackTrace();
                }
                //incomingCall=call;
            }
        };
      //  showIncomingCallGui(intent, context);
        incomeScreen wtActivity = (incomeScreen)context;
        incomingCall = wtActivity.mSipManager.takeAudioCall(intent, listener);
        wtActivity.call = incomingCall;
        Log.d("Manager", wtActivity.mSipManager.toString());
        if(incomingCall.isMuted()) {
            incomingCall.toggleMute();
        }
       showIncomingCallGui(intent,context);

    } catch (Exception e) {
        if (incomingCall != null) {
            incomingCall.close();
        }
    }
}
public void accept()
{
    Log.d("Receiver","Answer");
    try {
            incomingCall.answerCall(30);
            incomingCall.startAudio();
            incomingCall.setSpeakerMode(true);
    } catch (SipException e) {
        Log.d("Call Exception",e.toString());
        e.printStackTrace();
    }
    catch (Exception e)
    {
        Log.d("Exception",e.toString());
    }
}
public void showIncomingCallGui(Intent intent,Context context) {
    Intent incomingCall=new Intent(context,incomeScreen.class);
   incomingCall.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    context.startActivity(incomingCall);
}
}

在这里我附上了我的传入屏幕源代码incomingscreen

package example.com.myapplication;

import android.app.PendingIntent;
import android.content.Intent;
import android.content.IntentFilter;
import android.net.sip.SipAudioCall;
import android.net.sip.SipException;
import android.net.sip.SipManager;
import android.net.sip.SipProfile;
import android.net.sip.SipRegistrationListener;
import android.os.Bundle;
import android.app.Activity;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;

import java.text.ParseException;

public class incomeScreen extends Activity {
public SipProfile mSipProfile = null;
public SipProfile.Builder builder = null;
public MyService service;
public SipAudioCall call = null;
public SipManager mSipManager;
public EditText username,password,domain;
public IncomingReceiver callReceiver;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_income_screen);
    //service=new MyService();
    mSipManager=MyService.sipManager2;
    IntentFilter filter = new IntentFilter();
    filter.addAction("example.com.myapplication.INCOMING_CALL");
    callReceiver = new IncomingReceiver();
    this.registerReceiver(callReceiver, filter);
    if(callReceiver!=null)
    {
        unregisterReceiver(callReceiver);
    }
    Button b1 = (Button) findViewById(R.id.Accept);

    b1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            callReceiver.accept();
            Log.d("ManagerSIp",mSipManager.toString());
        }
    });

}
}

这是我的错误日志

我参加聚会迟到了，但这可能对其他人有所帮助。

虽然我正在处理类似的问题，但据我了解，与 Android 中的前台应用程序（活动）所需的权限相比，后台服务需要单独的权限。

如果您在 Android Manifest 中具有特定权限类型，则不足以让您在服务中使用相同的代码。例如，当我使用代码注册 SIP 服务器时，我的 USES_SIP 权限会出错。相同的代码可以在活动中正常工作。

现在我正在启动一个活动来接收呼叫并从该活动注册 BroadcastReceiver ，因此已授予权限。

您的 NullPointerException 不是很详细，但很可能是因为权限。

当您写“native sip”时，您是指与 Android 一起提供的预打包 SIP，还是与您的应用程序捆绑在一起并可能由您构建的本地 SIP 二进制文件（例如 PJSIP、Linphone 等）？

如果是后者，您将无法通过 Android API 执行您正在执行的操作。您需要使用 SIP 堆栈的 API。
