Question

locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
                Location location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
                double longitude = location.getLongitude();
                double latitude = location.getLatitude();
                if(Geocoder.isPresent()){
                Geocoder gcd = new Geocoder(context, Locale.getDefault());
                try {
                    List<Address> addresses = gcd.getFromLocation(latitude, longitude, 1);
                    if(addresses != null) {
                        Address returnedAddress = addresses.get(0);
                        StringBuilder strReturnedAddress = new StringBuilder("Address:\n");
                        for(int i=0; i<returnedAddress.getMaxAddressLineIndex(); i++) {
                            strReturnedAddress.append(returnedAddress.getAddressLine(i)).append("\n");
                        }
                     weatherLocation =  strReturnedAddress.toString();
                    }
                }
                 catch (IOException e) {

                    e.printStackTrace();
                }
                }

IDE没有错误。我已经尝试了所有我能想到的东西。每当执行此方法时，应用程序崩溃。（这是该方法中唯一的代码）

logcat的：

崩溃的Logcat。

Answer 1

检查您的registermessage(View ...)方法。也许你的xml / Activity中有拼写错误。如果对片段使用android:onClick="..."的布局，请记住相应的onClick方法必须在Activity中。

涉及位置服务的代码行会导致应用程序崩溃
