wZip

An android library the provides zip and unzip functionality. This uses the default implementation of ZipInputStream and ZipOutputStream to read and generate the zip files.

Gradle

maven { url 'https://jitpack.io' }

dependencies {
    implementation 'com.github.wwdablu:wZip:x.y.z'
}

Usage

wZip library provides only 2 methods:

• zip
• unzip

The process to generate a zip archive is to provide the list of files and the destination where the zip is to be generated.

zip(this@MainActivity, // Context
    dfList,            // List of DocumentFile pointing to the individual files
    it,                // DocumentFile pointing to the zip file to be created
    "Zipper",          // Name of the zip process
    this@MainActivity) // Callback implementation

The process to unzip the contents and extract them to a folder is:

unzip(this@MainActivity, // Context
      zipFile,           // DocumentFile pointing to the zip file
      it,                // DocumentFile pointing to the directory to be extracted into
      "Unzipper",        // Name of the zip process
      this@MainActivity) // Callback implementation

wZip also provides 4 callback methods to notify the states of the process.

fun onStart(worker: String, mode: Mode)
fun onZipComplete(worker: String, zipFile: DocumentFile)
fun onUnzipComplete(worker: String, extractedFolder: DocumentFile)
fun onError(worker: String, e: Exception, mode: Mode)

Note

It uses DocumentFile for access to the files and creating the ZIP file.
