Я новичок в андроида программирования и я написал этот код, который разбирает THT видимую экрана, чтобы получить верхний левый и нижний правый угол cordinates, а затем передает значения в WebService,App сбоями Проходя значение веб-службы
http://hiscentral.cuahsi.org/webservices/hiscentral.asmx?op=GetSeriesCatalogForBox2
теперь, когда я передавал значения по умолчанию xmin xmax ymin и ymax, тогда приложение работает нормально, но затем, когда я использую функцию MapView, чтобы получить угловое сердце, а затем передать их веб-службе, приложение перестанет работать.
я был бы очень благодарен, если вы могли бы мне помочь с этим, спасибо заранее
