我在这里附加了我的广播接收器文件 BroadCast接收器文件
Here i have attached my broadcast Receiver file BroadCast Receiver File
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 传入屏幕
here i have attached my incoming screen source code 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

请帮助我解决
推荐答案
我参加聚会很晚，但可能会帮助其他人.
I'm late to the party but it may help others.
虽然我正在处理类似的问题，但据我了解，后台服务需要独立的权限，而Android中的前台应用程序(活动)则需要单独的权限.
While I'm working on a similar problem, what I understand , background services need separate permissions as compared to permissions needed for foreground applications (activities) in Android.
如果您在Android清单中具有特定的权限类型，则不足以允许您在服务中使用相同的代码.例如，当我使用代码向SIP服务器注册时，对我的USES_SIP权限给出了错误.相同的代码在活动中也可以正常工作.
If you have for a particular permission type in your Android Manifest, that is not sufficient to allow you to use the same code in a service. For example USES_SIP permission for me was giving error when i used the code for registering with a SIP server. The same code works fine from an activity.
目前，我正在启动一个活动以接收呼叫并从该活动注册BroadcastReceiver，因此已授予了权限.
For now I'm launching an activity to receive calls and register BroadcastReceiver from the activity , hence have the permissions granted.
您的NullPointerException不是很复杂，但是很可能是由于权限的原因.
Your NullPointerException is not very elaborate , but most probably its because of the permissions.
