Hi,

my app works very well, but only in one device, a Samsung Tab 2 7" with Android 4.1.2

i get "Invalid license key" when i try to create Debenu !

Any ideas what's wrong?

Regards

Stefan

Hi Stefan,

a code snippet to check your syntax would be great ;-)

What's the meaning of "i try to create debenu"?

There are different versions of the library.

For windows, android, and so on ...

Due to this i can imagine that each license key is only valid for one library version?

Here a few lines of code:

{$IFDEF ANDROID}

SharedObjectFileName := TPath.Combine(TPath.GetDocumentsPath,

'libDebenuPDFLibraryAndroidArm1311.so');

if fileexists(SharedObjectFileName) = False then

Showmessage('*.SO-File missing!');

PDFLibrary := TDebenuPDFLibraryCPAndroidDelphi1311.Create

(SharedObjectFileName);

key := GetPDFKey(); //geting my key, stored in a special path

{$ENDIF}

{$IFDEF MSWINDOWS}

PDFLibrary := TDebenuPDFLibrary1311.Create;

key := GetPDFKey();

{$ENDIF}

UnlockResult := PDFLibrary.UnlockKey(key);

if UnlockResult <> 1 then

Showmessage('Invalid License Key !');

At the special device UnlockResult = 0 and i don't know why :-(((

This code works with all Windows and Android devices, only the ode will not work!

The user has set his Tablet to factory default and the problem is always ...

Ciao

Hi,

in the meantime i have moved on and found that the library is not loaded! Even when the library is not loaded, unlockkey result = 0 (like bad license key). What could be the cause?

Ciao

Hi Stefan,

you should check the resulting value from loadfromfile.

There'll be the first error.

Using unlock will only raise a following error.

Using unlock without loading returns with 0 (nothing) - this should be normal behavior?
