Classes

TypeReason
AndroidExceptionBase class for all checked exceptions thrown by the Android frameworks.
AndroidRuntimeExceptionBase class for all unchecked exceptions thrown by the Android frameworks.
ArrayMapArrayMap is a generic key->value mapping data structure that is designed to be more memory efficient than a traditional Android.Runtime.JavaDictionary.

FloatMathMath routines similar to those found in Java.Lang.Math.
IAttributeSetA collection of attributes, as found associated with a tag in an XML document.
IPrinterSimple interface for printing text, allowing redirection to various targets.
IPrinterExtensionsDocumentation for this section has not yet been entered.
JsonReaderReads a JSON () encoded value as a stream of tokens.
JsonTokenA structure, name or value type in a JSON-encoded string.
JsonWriterWrites a JSON () encoded value to a stream, one token at a time.
LayoutDirectionA class for defining layout directions.
LayoutDirectionsEnumerates values returned by several types.
LogAPI for sending log output.

LogPriorityEnumerates values returned by several methods of Android.Util.LogPriority and taken as a parameter of several types.
LongSparseArraySparseArray mapping longs to Objects.
LruCacheA cache that holds strong references to a limited number of values.

MutableBoolean [Android Documentation]
MutableByte [Android Documentation]
MutableChar [Android Documentation]
MutableDouble [Android Documentation]
MutableFloat [Android Documentation]
MutableInt [Android Documentation]

NoSuchPropertyExceptionThrown when code requests a Android.Util.Property on a class that does not expose the appropriate method or field.
PairContainer to ease passing around a tuple of two objects.
PatternsCommonly used regular expression patterns.

PropertyA property is an abstraction that can be used to represent a mutable value that is held in a host object. The Property's Android.Util.Property.set(T, V) or Android.Util.Property.get(T) methods can be implemented in terms of the private fields of the host object, or via "setter" and "getter" methods or by some other mechanism, as appropriate.

SparseIntArraySparseIntArrays map integers to integers.
SparseLongArraySparseLongArrays map integers to longs.
StateSetState sets are arrays of positive ints where each element represents the state of a Android.Views.View (e.g. focused, selected, visible, etc.

TimeUtilsA class containing utility methods related to time zones.
TimingLoggerA utility class to help log timings splits throughout a method call.
TypedValueContainer for a dynamically typed data value.
XmlXML utility methods.
Xml+EncodingSupported character encodings.
