Ответ 1
Проблема заключается в методе onActivityResult() для KitKat, который возвращает URI. Вам нужно получить реальную траекторию файла изображений.
Обратите внимание, как я получаю реальный путь IMG, вызывая:
KitkatPath = Uri.parse( "file://" + getPath (MobilestyxAppActivity.this, результат)); в onActivityResult().
Вы должны добавить строку "file://", чтобы она работала.
PS: Я собрал код из разных источников и изменил его.
Посмотрите мой код ниже, который работает для Kitkat и Lolipop и других низких версий Android.
