Creation of new document returns error -10

I have the Premium license. I'm trying to create a new PDF document on internal storage, but I always get error -10. See my code below:

final String path = getFilesDir() + "/result.pdf";
Document dest = new Document();
int result = dest.Create(path);

We have checked your code and it's working with the demo project (activated with a premium license), check the screenshot:



The method returns -10 in 3 cases:
--path is null or invalid
--premium license is not actived.
--can't create/open file for path, if occoured.
The path is aparently valid, so make sure that the premium license is activated correctly, and that there is no write-premission problem.

I'm doing the following to activate the Premium license:
Global.Init(this, 2, "Gaia Mobile", "[email protected]", "");
Is all right?

The method call is correct, but we have realized that the key was calculated based on a wrong package name...
Soon you will recieve the correct key calculated based on the correct package name.

When the license will be activated correctly, the watermark should disappear, and the method Global.Init should return true.
