PathClassLoader

Provides a simple ClassLoader implementation that operates on a list of files and directories in the local file system, but does not attempt to load classes from the network. Android uses this class for its system class loader and for its application class loader(s).

Inherited Methods

From class dalvik.system.BaseDexClassLoader

Class<?>	findClass( String name) Overridden by subclasses, throws a `ClassNotFoundException` by default.
String	findLibrary( String name) Returns the absolute path of the native library with the specified name, or `null`.
URL	findResource( String name) Finds the URL of the resource with the specified name.
Enumeration< URL>	findResources( String name) Finds an enumeration of URLs for the resource with the specified name.
synchronized Package	getPackage( String name) Returns package information for the given package.
String	toString() Returns a string containing a concise, human-readable description of this object.

From class java.lang.ClassLoader

void	clearAssertionStatus() Sets the default assertion status for this class loader to `false` and removes any package default and class assertion status settings.
final Class<?>	defineClass( String name, ByteBuffer b, ProtectionDomain protectionDomain) Defines a new class with the specified name, byte code from the byte buffer and the optional protection domain.
final Class<?>	defineClass( String className, byte[] classRep, int offset, int length, ProtectionDomain protectionDomain) Constructs a new class from an array of bytes containing a class definition in class file format and assigns the specified protection domain to the new class.
final Class<?>	defineClass( String className, byte[] classRep, int offset, int length) Constructs a new class from an array of bytes containing a class definition in class file format.
final Class<?>	defineClass(byte[] classRep, int offset, int length) This method was deprecated in API level 1. Use `defineClass(String, byte[], int, int)`

String	findLibrary( String libName) Returns the absolute path of the native library with the specified name, or `null`.
final Class<?>	findLoadedClass( String className) Returns the class with the specified name if it has already been loaded by the VM or `null` if it has not yet been loaded.
URL	findResource( String resName) Finds the URL of the resource with the specified name.
Enumeration< URL>	findResources( String resName) Finds an enumeration of URLs for the resource with the specified name.
final Class<?>	findSystemClass( String className) Finds the class with the specified name, loading it using the system class loader if necessary.

Class<?>	loadClass( String className, boolean resolve) Loads the class with the specified name, optionally linking it after loading.
Class<?>	loadClass( String className) Loads the class with the specified name.
final void	resolveClass( Class<?> clazz) Forces a class to be linked (initialized).
void	setClassAssertionStatus( String cname, boolean enable) Sets the assertion status of the class with the specified name.
void	setDefaultAssertionStatus(boolean enable) Sets the default assertion status for this class loader.
void	setPackageAssertionStatus( String pname, boolean enable) Sets the assertion status of the package with the specified name.

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals( Object o) Compares this instance with the specified object and indicates if they are equal.

Public Constructors

public PathClassLoader (String dexPath, ClassLoader parent)

Added in API level 1

Creates a PathClassLoader that operates on a given list of files and directories. This method is equivalent to calling PathClassLoader(String, String, ClassLoader) with a null value for the second argument (see description there).

Parameters

dexPath	the list of jar/apk files containing classes and resources, delimited by `File.pathSeparator`, which defaults to `":"` on Android
parent	the parent class loader

public PathClassLoader (String dexPath, String libraryPath, ClassLoader parent)

Added in API level 1

Creates a PathClassLoader that operates on two given lists of files and directories. The entries of the first list should be one of the following:

JAR/ZIP/APK files, possibly containing a "classes.dex" file as well as arbitrary resources.
Raw ".dex" files (not inside a zip file).

The entries of the second list should be directories containing native library files.

Parameters

dexPath	the list of jar/apk files containing classes and resources, delimited by `File.pathSeparator`, which defaults to `":"` on Android
libraryPath	the list of directories containing native libraries, delimited by `File.pathSeparator`; may be `null`
parent	the parent class loader
