@netas,

Thanks for the details.

Do you use Aspose.Cells for Android via Java, make sure you are using the right (Android) library jars. Please see the document and follow the guidelines on how to setup Aspose.Cells for Android via Java in Android Studio IDE for your reference:

Let us know if you still find any issue.

No problem when compiling in DEBUG mode I get an error (ExceptionInInitializerError) when compiling in RELEASE mode, i think it’s permission problem ?

@netas,

Yes, your issue can be related to configuration or rights issue on your end. Anyways, we will also evaluate your issue further on our end.

I changed configuration gradle, like that;

implementation fileTree(include: [’*.jar’], dir: ‘libs’)
and i also added.
implementation files(‘libs/aspose-cells-17.12.jar’)

solved, thanks.
