KTagLib

Kotlin bindings for TagLib

Gradle:

Step 1. Add the Jitpack repository to the root build.gradle

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

Step 2. Add the dependency

dependencies {
    implementation("com.github.timusus:KTagLib:release-SNAPSHOT") // or kTagLib:1.5.1
}

See the sample app for an example of reading tags, using the Storage Access Framework.

Usage

Read Tags

Read the tags from a file descriptor:

KTagLib().getMetadata(fileDescriptor: Int)

This returns a Metadata object, containing the tags and audio properties of the audio file located at fileDescriptor, or null if none are found

Retrieve Artwork

KTagLib().getArtwork(fileDescriptor: Int)

Returns a ByteArray (or null) representing the image data of the largest image found.

Write Tags

fun writeMetadata(
    fileDescriptor: Int,
    properties : HashMap<String, ArrayList<String>>
): Boolean

Attempts to write the tags supplied via the map to the file located at fileDescriptor. Existing tags with the same key are replaced.

Returns true if the tags are successfully updated.
