saantiaguilera / Result.kt
Created January 14, 2021 17:07
Result sealed class for kotlin error handling, allowing us to write safe code either in a functional or imperative format, without the use of exceptions. Since kotlin from 1.3 onwards changed their Result into an inline class, we can no longer use it for return values (which eliminates the bad smell of exceptions as errors, like most modern lang…

Fresco picasso mode

Juanma tutorial for using Fresco as "Picasso"

La diferencia mas grande entre picasso y fresco es que (por si te preguntan):

Android <4.0 usa como vm Dalvik. De 4.0 a 4.4 esta Dalvik y ART (Beta). >5.0 ART.

Las mayor diferencia entre Dalvik y ART, es que dalvik tiene un solo heap uniforme y que, cada vez que corra el garbage collector, haltea TODOS los procesos para limpiar la memoria. Entonces en los celulares de dalvik, si empezas a usar mucha memoria y tiene que recolectarla, se te "freezea" el celular por unos ms.

Esto se nota demasiado en las listviews/gridviews/recyclerviews, ya que uno levanta muchisima memoria y se recolecta al toque, pero en dalvik esto haltea ;).
