Unable to connect to this library

I have added implementation 'com.github.aagarwal1012:Image-Steganography-Library-Android:v1.0' but, when I implements TextEncodingCallback I am getting error. Like I am unable to connect to steganography-library

Decoding Error [ Incorrect Secret Key error ]

Describe the bug
I am using this key - "123456789A" during encoding & decoding. Encoding is successful (despite result.getSecretKey() returning null) . But during Decoding , I receive error that Secret Key is wrong ( result.issecretkeywrong returned true). All others seems fine. Below are the screenshots of code fragments & error log. Thanks for ur assistance & the great library! Regards from Malaysia.

Gradle implementation does not resolve

Describe the bug
I have tried to follow your instructions to add your library to my project, When I add "implementation 'com.github.aagarwal1012:Image-Steganography-Library-Android:v1.0'" into the build.gradle I get the following error.

ERROR: Failed to resolve: com.github.aagarwal1012:Image-Steganography-Library-Android:v1.0

Is it possible to get the original png image after extracting the encrypted message?

I want to split the image and text to its original state

Unable to save the encoded message

Hi, I got an error when I built this app on my smartphone. I was not able to save the encoded image, and after I click "ENCODED" button and "SAVE IMAGE" button. I got two same error messages:

2020-12-08 23:38:06.105 21616-21616/com.ayush.steganography E/DecorView: mWindow.mActivityCurrentConfig is null
2020-12-08 23:38:06.469 21616-21616/com.ayush.steganography E/ViewRootImpl: sendUserActionEvent() mView returned.

Also, folder Android/data/com.ayush.steganography/files/Documents// was not showing.

Any ideas about these two problems?

Thanks

Secret key of length >16 doesn't work

Describe the bug
If the user passes secret key of length >16 to ImageSteganography constructor the convertKeyTo128bit method won't convert it properly.
Instead of:
result = result.substring(0, 16);
it has:
result = result.substring(0, 15);

And the encryption step fails then.

Possible solution without the pull request
It is easy to fix in the library, but if it won't be fixed here is an easy workaround:

Create class ImageSteganographyV2 which extends ImageSteganography
Copy the whole code(since ImageSteganography doesn't open access to fields)
Fix the bug by changing 15 to 16 in "result = result.substring(0, 15);"
Create ImageSteganography instances using new class. For example:

ImageSteganography imageSteganography = new ImageSteganographyV2(message, secretKey, originalImage);

Everything else can stay the same
