# zip-android 
Android JNI bindings for [zip-rs](https://github.com/zip-rs/zip), a native rust zip library.
### Installation
```kotlin
repositories {
mavenCentral()
}
dependencies {
implementation("io.github.diamondminer88:zip-android:2.1.1@aar")
}
```
### Example Usage (Kotlin)
```kotlin
ZipReader(zipFile).use { zip ->
"Entry count: ${zip.entryCount}"
"Entries: ${zip.entryNames.joinToString()}"
// Loop over entries
zip.entries().forEach { /* guh */ }
zip.forEach {
"Entry: ${it.name} size: ${it.size} modified: ${it.lastModified}"
if (it.isFile) {
"Content: ${it.read().decodeToString()}"
}
}
}
// Close reader/writer by using .use {} (kotlin) or .close()/try block for java
ZipWriter(zipFile).use { zip ->
zip.setComment("a comment".toByteArray())
zip.writeEntry("compressed.txt", "hot garbage")
zip.writeEntry("data/compressed_bytes.txt", bytes)
zip.writeDir("com/github/diamondminer88/zip")
zip.deleteEntries("abc.txt", "guh.txt")
zip.deleteEntry("husk.txt")
// Delete entry from central dir and keep the existing alignment (useful for writing zip aligned .so's)
zip.deleteEntry("lib.so", /* fillVoid = */ true)
// Write page-aligned (4096 byte) uncompressed entry (useful for writing zip aligned .so's)
zip.writeEntry("lib.so", bytes, ZipCompression.NONE, 4096)
}
```
