Here i have attached my broadcast Receiver file BroadCast Receiver File

@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) {

}
public void showIncomingCallGui(Intent intent,Context context) {
Intent incomingCall=new Intent(context,incomeScreen.class);
incomingCall.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(incomingCall);
}
}
here i have attached my incoming screen source code incomingscreen
package example.com.myapplication;
import android.app.PendingIntent;
import android.content.Intent;

public IncomingReceiver callReceiver;
@Override

//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());
}
});
}
}
Here comes my error log
02-15 12:01:03.334 3921-3921/example.com.myapplication D/Receiver: Answer
02-15 12:01:03.334 3921-3921/example.com.myapplication D/Exception: java.lang.NullPointerException
kindly please help me to solve
回答1:
I'm late to the party but it may help others.
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.
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.
For now I'm launching an activity to receive calls and register BroadcastReceiver from the activity , hence have the permissions granted.
Your NullPointerException is not very elaborate , but most probably its because of the permissions.

回答2:
When you write "native sip", do you mean the pre-packaged SIP that comes w/Android or a native SIP binary bundled w/your application and presumably built by you (such as PJSIP, Linphone, etc.)?
If it's the latter, you cannot do what you are doing through the Android API. You need to use your SIP stack's API.
