A Fonts Cache mechanism that can be used in your project right away. Do you know that creating a typeface object from resources every time you set a font to your views is memory expensive? Use this simple helper class to avoid such memory leaks and improve your app's performance.

FontsHelper.kt

import android.content.Context
import android.graphics.Typeface
import com.zoho.zohosocial.utils.MLog
import java.util.*


object FontsHelper {
    private val TAG = "TypefaceHelper"

    private val fontsCache = Hashtable<String, Typeface>()

    operator fun get(c: Context, assetPath: String): Typeface? {
        if (!fontsCache.containsKey(assetPath)) {
            try {
                fontsCache[assetPath] = Typeface.createFromAsset(c.assets, "fonts/$assetPath")
            } catch (e: Exception) {
                MLog.e(TAG, "Could not get typeface '" + assetPath + "' because " + e.message)
                return null
            }
        }
        return fontsCache[assetPath]
    }
}
