How does getExternalCacheDir() work on Android?
<p>From what I understand, we cache the frequently accessed objects in a memory segment that is more easily accessible than normal disk reads.</p>

<p>getExternalCacheDir(), as opposed to getCacheDir() points to the external filesystem - which seems to me as a normal getExternalFilesDir(). How does Android optimize access to ExternalCacheDiir ? Is it something like the "swap" space on Linux ?</p>

<p>Thanks !</p>
