All Implemented Interfaces:

AsyncInitSoSource

public class BackupSoSource
extends ExtractFromZipSoSource

SoSource that extracts zipped libraries from an APK to the filesystem. This is a workaround for a known OS bug where the unpacking of non-asset zipped libraries at install time results in corrupted libraries (e.g. bad elf magic, or truncated files).
