I understand that WeakReferences are especially suited to implement Caches.
Are there other scenarios whereby WeakReferences are suitable on a mobile platform like Android ?
I understand that Android reclaims memory itself by killing processes.

Weak references are used to prevent circular references too.

Android's Dalvik VM does garbage collection just like your desktop version of Java SE does.
In addition to that, when memory gets tight, paused applications can be killed. If they're needed later they are reconstituted from saved state.
