LibraryLoader

@UnstableApi
public abstract class LibraryLoader


Configurable loader for native libraries.

Summary

Public fields

boolean

Public constructors

LibraryLoader(String[] libraries)

Public methods

synchronized boolean

Returns whether the underlying libraries are available, loading them if necessary.

synchronized void
setLibraries(String[] libraries)

Overrides the names of the libraries to load.

Protected methods

abstract void

Should be implemented to call System.loadLibrary(name).

Public fields

isAvailable

public boolean isAvailable

Public constructors

LibraryLoader

public LibraryLoader(String[] libraries)
Parameters
String[] libraries

The names of the libraries to load.

Public methods

isAvailable

synchronized public boolean isAvailable()

Returns whether the underlying libraries are available, loading them if necessary.

setLibraries

synchronized public void setLibraries(String[] libraries)

Overrides the names of the libraries to load. Must be called before any call to isAvailable.

Protected methods

loadLibrary

protected abstract void loadLibrary(String name)

Should be implemented to call System.loadLibrary(name).

It's necessary for each subclass to implement this method because loadLibrary uses reflection to obtain the calling class, which is then used to obtain the class loader to use when loading the native library. If this class were to implement the method directly, and if a subclass were to have a different class loader, then loading of the native library would fail.

Parameters
String name

The name of the library to load.
