                                });
                        dialog.show();

解决方案

The broadcast receive is app service(intent service). The intent service have a few limitations the first one and most important is 'It can't interact directly with your user interface'.

Then you have a alternative you can try to work with handle if your app it's open and then the handle captures message and throws dialog from handle. Tell me if I helped you and good programming!
