Smartphone (please complete the following information):

• Device: Nexus 5
• OS: Android 6.0.1, API 23
• Library version 2.12.0

Additional context
It may be caused by the obfuscation...

Looks like this line in MaterialTapTargetPrompt.java

info.setPackageName(PromptView.this.getClass().getPackage().getName());

This does look like obfuscation

Going on the JavaDoc getPackage() returns null if no package information is available from the archive or codebase. Obfuscation could be removing it or the class loader isn't finding it for another reason

I will add a check for package being null. When it is null the default value for the contexts package will be used

Changes have been released in v2.12.1, please let me know if these changes resolve this

[CameliaTripon]

Thank you for the quick fix. This should solve the issue.
And btw, really nice library
