Method Detail

getAllEntries

getAssetFileDescriptor

public android.content.res.AssetFileDescriptor getAssetFileDescriptor(String assetPath)

getAssetFileDescriptor allows for ZipResourceFile to directly feed Android API's that want an fd, offset, and length such as the MediaPlayer. It also allows for the class to be used in a content provider that can feed video players. The file must be stored (non-compressed) in the Zip file for this to work.

Parameters:

assetPath -

Returns:

the asset file descriptor for the file, or null if the file isn't present or is stored compressed

getInputStream

public InputStream getInputStream(String assetPath)
                           throws IOException

getInputStream returns an AssetFileDescriptor.AutoCloseInputStream associated with the asset that is contained in the Zip file, or a standard ZipInputStream if necessary to uncompress the file

Parameters:

assetPath -

Returns:

an input stream for the named asset path, or null if not found

Throws:

IOException
