If you receive an exception like this, please make sure that you follow the next steps:
1) Properly implemented your license key in the activity where you initialize and call the wanted recognizers for the scanning process. Have in mind that the license key must be implemented on the onCreate() method, when the view loads.
2) In your AndroidManifest.xml file make sure that you have set up android:name property
3) Please make sure that you are using the correct package name and license key file generated from the Microblink Dashboard in your app build.gradle file.
4) If non of the above steps work, please contact us directly with logcat and your license key/license key file at firstname.lastname@example.org
