Я создаю приложение ложного местоположения, но когда я его включаю, другие приложения (например, Google Maps) его не обнаруживают. В приложении я могу определить реальное местоположение, если включен gps, и ложное местоположение, если gps выключен, а приложение включено в приложениях для определения местоположения

Мой код:

Приложения должны явно запрашивать положение ложного местоположения. Если они не запрашивают макет, они получат реальное местоположение независимо от того, существует ли макет. Большинство разработчиков не оставляют запрос ложного разрешения в коде выпуска, чтобы приложение не было обмануто.

В общем, ложное местоположение — это инструмент для отладки ваших приложений, использующих местоположение, а не инструмент для обмана приложений, которые не хотят отлаживаться.
