Question

I just want to know how to launch an Activity in a try/catch bloc, i made this

    public void onReceive(Context context, Intent intent) {
            SipAudioCall incomingCall = null;
            try {
                Intent monIntent = new Intent(this,dialog.class);
                startActivity(monIntent);
                SipAudioCall.Listener listener = new SipAudioCall.Listener() {
@Override
                public void onRinging(SipAudioCall call, SipProfile caller) {

But i have errors:

constructor Intent(IncomingCallReceiver, Class<dialog>) is not defined
Method startActivity(Intent) is undefined for the type IncomingCallReceiver

I want to show an alertdialog when having a call.
How can i solve this problem?

Thank you very much.
Whole class:

public class IncomingCallReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        SipAudioCall incomingCall = null;
        try {

            SipAudioCall.Listener listener = new SipAudioCall.Listener() {
                @Override
                public void onRinging(SipAudioCall call, SipProfile caller) {
                    try {
                        call.answerCall(30);
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }
            };

            SIPCommunicator wtActivity = (SIPCommunicator) context;

            incomingCall = wtActivity.manager.takeAudioCall(intent, listener);
            incomingCall.answerCall(30);
            incomingCall.startAudio();
            incomingCall.setSpeakerMode(true);
            if(incomingCall.isMuted()) {
                incomingCall.toggleMute();
            }

            wtActivity.call = incomingCall;

            wtActivity.updateStatus(incomingCall);

        } catch (Exception e) {
            if (incomingCall != null) {
                incomingCall.close();
            }
        }
    }

}

The problem you are facing is not the try catch block, it’s the fact that you are starting activity in a listener implementation. Substitute

Intent monIntent = new Intent(this,dialog.class);

with

Intent monIntent = new Intent(<Name of this class>.this,dialog.class);

and

 startActivity(monIntent);

with

<Name of this class>.this.startActivity(monIntent);

By <Name of this class> I mean the head class where you are writing your code.
