Input byte array has incorrect ending byte at 40

Question

I have a string that is base64 encoded. It looks like this:

eyJibGExIjoiYmxhMSIsImJsYTIiOiJibGEyIn0=

Any online tool can decode this to the pro

Answer 1

Maybe too late, but I also had this problem.

By default, the Android Base64 util adds a newline character to the end of the encoded string.
The Base64.NO_WRAP flag tells the util to create the encoded string without the newline character.

Your android app should encode src something like this:

String encode = Base64.encodeToString(src.getBytes(), Base64.NO_WRAP);
