Log	API for sending log output.
LruCache<K, V>	A cache that holds strong references to a limited number of values.
Pair<F, S>	Container to ease passing around a tuple of two objects.
SparseArray<E>	SparseArrays map integers to Objects.
SparseBooleanArray	SparseBooleanArrays map integers to booleans.
SparseIntArray	SparseIntArrays map integers to integers.
SparseLongArray	SparseLongArrays map integers to longs.
