DexClassLoader

open class DexClassLoader : BaseDexClassLoader
kotlin.Any
   ↳ java.lang.ClassLoader
   ↳ dalvik.system.BaseDexClassLoader
   ↳ dalvik.system.DexClassLoader

A class loader that loads classes from .jar and .apk files containing a classes.dex entry. This can be used to execute code not installed as part of an application.

Prior to API level 26, this class loader requires an application-private, writable directory to cache optimized classes. Use Context.getCodeCacheDir() to create such a directory:

<code>File dexOutputDir = context.getCodeCacheDir();
  </code>

Do not cache optimized classes on external storage. External storage does not provide access controls necessary to protect your application from code injection attacks.

Added in API level 3
DexClassLoader(
    dexPath: String!,
    optimizedDirectory: String!,
    librarySearchPath: String!,
    parent: ClassLoader!)

Creates a DexClassLoader that finds interpreted and native code. Interpreted classes are found in a set of DEX files contained in Jar or APK files.

The path lists are separated using the character specified by the path.separator system property, which defaults to :.

Parameters
dexPath String!: the list of jar/apk files containing classes and resources, delimited by File.pathSeparator, which defaults to ":" on Android
optimizedDirectory String!: this parameter is deprecated and has no effect since API level 26.
librarySearchPath String!: the list of directories containing native libraries, delimited by File.pathSeparator; may be null
parent ClassLoader!: the parent class loader
