Я попробовал файл C как .cpp и используется Экстерн «C» всеми возможными способами безрезультатно. Я также удалил папки bin, out, libs и obj несколько раз и только что построил. Содержит код и файлы .so.
Но я не могу запустить его это журнал

По какой-то причине этот метод не видел, и все же библиотека загружается .... для чего это стоит, я редактировал этот код от here и достал то, что мне нужно. Thanx
Запустите ndk-build -b V = 1 и вставьте выходной файл, проблема, вероятно, связана с созданием/связыванием библиотеки, в которой выполняется преобразование. –
