Before Android5.0，I use DexClassloader load plugin dynamiclly，code like this：</p>
DexClassLoader localDexClassLoader = new DexClassLoader(pluginSrcJarDir,cont.getDir("dex", 0).getAbsolutePath(), null, ClassLoader.getSystemClassLoader().getParent());
Class<?> pluginClass = localDexClassLoader.loadClass(className); //error here
but on Android5.0 here is the error：</p>
