Base 64 Encoded QRGen QR code can't be decoded

Asked 2020-Oct-21 at 20:51

Im trying to generate a QR code using QRGen, encode it in Base64 and insert it as an image in an HTML string. Later, the HTML string is decoded to be displayed in a JEditorPane (and then sent to a printer). To this end, the ImageView class is extended and a custom View factory is used. This all works fine... sometimes. It completely depends on the input string. Some strings work without issue, others fail cause the decode process to fail with the error java.lang.IllegalArgumentException: Input byte array has wrong 4-byte ending unit.

Here is the encode process:

CakeResponse::file() expects a file system path passed to it, not a URL, it's not going to make any HTTP requests to obtain the data.

You have to obtain the data yourself, and then either buffer it in a temporary file whose path in the filesystem you can pass to CakeResponse::file():

So there are two possible duplicates of this question: here and here. They both come to conclusion that upgrading your Android Support Library to the latest version will fix the problem. Along with that, a clean and rebuild of the project and a restart of Android Studio could also help.
