Мы используем функциональность камеры в нашем приложении. Приложение также будет опубликовано в Google App Store. но мы столкнулись с новой проблемой: setParameters не удалось в нашем приложении, некоторые устройства только как moto g второго поколения. Пожалуйста, найдите консоль ошибок и кодировку SurfaceView ниже. Как решить эту проблему, пожалуйста, помогите мне. БлагодаряКак разрешить Android-камеру setParameters не удалось
