MultiDex Offline

A Context-less version of MultiDex Suport library, this modified version for those cases where the context is unknown (like in a xposed module).

Modified version based on 2.0.1 from androidx (tree 652081201e50f0766dcfd7c650ef91d417f48597).

    public class MultiDexOffline {
        public static void install(
            SharedPreferences prefs,
            ApplicationInfo applicationInfo,
            String filesDir,
            ClassLoader classLoader
        );
    }

Summary:

Patches the application context class loader in the desired app by appending extra dex files loaded from the application apk. This method should be called once.

Parameters:

• prefs where save preference and to get the current dex version
• filesDir Application private storage path, normally obtained from Context.getFilesDir()
• classLoader classloader to patch.
• throws RuntimeException if an error occurred preventing the classloader extension.

Notes:

• Please use MultiDexExtractor.PREFS_FILE for the prefences filename, inside of shared_prefs folder under private files app. Example /data/data/com.example.app/shared_prefs/multidex.version.
• If the target app already has the MultiDex support library, will be installed anyway (cannot be detected)
