Я делаю FlashLight, и когда друг пытается это сделать, у него случился сбой. Он имеет V 4.0+ Вот мой LogCat:У меня проблемы с Android 4.0+ Но нет в 2.2
https://github.com/Hersix/LogCat-FlashLightAPP/commit/9fa44813cdad14f461c14070cc0eea6e8c29c93a
Я новичок, но я читал, что приложения с потоками в версии 4.0+ Сбои, так .. я не понимаю хорошо, но, как могу ли я поместить весь свой код без потока? Это мое приложение код:
