How do I get the license?

You can run examples and even develop your app without a license. If you do not specify the license in AndroidManifest then SDK will work in trial mode (currently, for 1 minute). If this is not enough for you, contact us at and we'll give you a free trial license for longer period.

What is the latest version of the SDK?

Current version is 1.19.0

Why example is not working / stopped working

Either your trial period is expired or you set the license incorrectly. Please, double check that.


Please kindly take note of the following points when downloading the SDK:

  • This is a trial version and will only work for 1 minute (if you require a trial license which works for a longer period of time please contact us).
  • We are constantly updating and evolving the SDK and it is no final product.
  • The SDK with a trial license should only be tested in a experimental setting and it is not developed to be integrated into your live products.
