The usual problem on Android and other phones is not the program heap but rather the heap (often separate) used for images. In particular on Android this is a problem that requires some special programming techniques if you're using a lot of images.
In Java, local variables "go out of scope" when you return from the method where they're declared. However, with some GC schemes there's a slight chance that a variable could have "life after death" when a new method is called that uses the same stack space, but the specific location of the variable isn't overwritten. (I don't think this is a problem on Android, as it has a "precise" garbage collector.)
