  // Create a Keystore and generate a key
  val keystore: Keystore = Keystore("samples-dataprotect")
  keystore.generateKey()
  
  // Encrypt data
  val plainText = "plain text data".toByteArray(StandardCharsets.UTF_8)
  val encrypted = keystore.encryptBytes(plain)
  
  // Decrypt data
  val samePlainText = keystore.decryptBytes(encrypted)
  

• concept-engine: Enhanced settings to cover most common WebView settings.

• browser-engine-system:

  • SystemEngineSession now provides a way to capture a screenshot of the actual content of the web page just by calling captureThumbnail

• browser-session:

  • Session exposes a new property called thumbnail and its internal observer also exposes a new listener onThumbnailChanged.

  session.register(object : Session.Observer {
      fun onThumbnailChanged(session: Session, bitmap: Bitmap?) {
              // Do Something
      }
  })
  

  • SessionManager lets you notify it when the OS is under low memory condition by calling to its new function onLowMemory.

• browser-tabstray:

  • Now on BrowserTabsTray every tab gets is own thumbnail :)

• support-ktx:

  • Now you can easily query if the OS is under low memory conditions, just by using isOSOnLowMemory() extension function on Context.

  val shouldReduceMemoryUsage = context.isOSOnLowMemory()
  
  if (shouldReduceMemoryUsage) {
      //Deallocate some heavy objects
  }
  

  • View.dp is nowResource.pxtoDp.

  // Before
  toolbar.dp(104)
  
  // Now
  toolbar.resources.pxToDp(104)
  

• samples-browser:

  • Updated to show the new features related to tab thumbnails. Be aware that this feature is only available for systemEngine and you have to switch to the build variant systemEngine*.
