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:1.6.1
}

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

Read the tags from a file descriptor:

KTagLib().getMetadata(fileDescriptor: Int, filename: String? = null)

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

The optional filename parameter helps with file type detection. Providing the filename (with extension) is recommended for better compatibility, especially for files with large metadata blocks.

KTagLib().getArtwork(fileDescriptor: Int, filename: String? = null)

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

The optional filename parameter helps with file type detection.

fun writeMetadata(
    fileDescriptor: Int,
    properties: HashMap<String, ArrayList<String>>,
    filename: String? = null
): 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.

The optional filename parameter helps with file type detection.
