Quoted from the link I provided above: "embedded system normally are reluctant to use eMMC or SDCard as swap because there is wear-leveling and latency issues" and "it sometime ends up making system very unresponsive caused by slow swap storage performance". | |

| Dec 27, 2021 at 16:55 | comment | added | Irfan Latif | As Robert said, saying that "Dalvik does not support swap space" does not make sense. Rather you can say that "Android does not support swap space". But it isn't true. Android is based on Linux kernel. And you can use a swap partition or swap file on Android exactly the same way as you'd do on a Linux PC. But you are correct in saying that Android devices by default do not use secondary storage for swap space. Instead engineers at Android decided to use ZRAM. | |

| Dec 27, 2021 at 15:16 | comment | added | Robert | Dalvik is the Android JVM (thus an program) and swap space is a feature of the OS. I a regular OS a program is never aware if it uses RAM or swap as the OS just provides memory. There are Android stock devices that are configured to have a small swap partition and of course a lot of custom ROMs make use of swap partitions. Therefore I am not sure what actually you are asking. | |
