Android util base64 cannot be resolved

Encoder that encodes using the MIME type base64 encoding scheme. Encoder that encodes using the MIME type base64 encoding scheme with specified line length and line separators.

Basic Encoding

Decoder getUrlDecoder Returns a Base Decoder that decodes using the URL and Filename safe type base64 encoding scheme. Encoder getUrlEncoder Returns a Base Encoder that encodes using the URL and Filename safe type base64 encoding scheme. Returns: A Base64 encoder. Parameters: lineLength - the length of each output line rounded down to nearest multiple of 4.

Returns: A Base64 decoder. That documentation contains more detailed, developer-targeted descriptions, with conceptual overviews, definitions of terms, workarounds, and working code examples. The encoder treats the encoded output stream as one line; no line separators are output. The decoder rejects an encoding that contains characters outside the Base64 alphabet. Note that these and other stipulations can be overridden.

The encoded output stream is organized into lines of no more than 76 characters; each line except the last line is separated from the next line via a line separator.

Access restriction: The type BASE64Encoder is not accessible due to restriction – alojosyhaj.ga

All line separators or other characters not found in the Base64 alphabet are ignored during decoding. No line separators are output.

The resulting URL string would be somewhat longer. Java 8 introduced a Base64 API consisting of the java.

Working with Java's Base64 API

Base64 class along with its Encoder and Decoder nested static classes. Base64 presents several static methods for obtaining encoders and decoders:. RFC 's encoder, which is returned from the noargument getMimeEncoder method, is rather rigid. For example, that encoder creates encoded text with fixed line lengths except for the last line of 76 characters. If you want an encoder to support RFC , which dicates a fixed line length of 64 characters, you need to use getMimeEncoder int lineLength, byte[] lineSeparator.

Base64 Encoding in Java 8

Encoder presents several threadsafe instance methods for encoding byte sequences. Passing the null reference to one of the following methods results in java. NullPointerException :. Decoder presents several threadsafe instance methods for decoding byte sequences.

Your Answer

Passing the null reference to one of the following methods results in NullPointerException :. What is Base64? Base64 encoding and decoding Base64 relies on simple encoding and decoding algorithms. There are two cases to consider: One remaining byte: Four zero bits are appended to this byte to form two 6-bit groups. Each group indexes the array and a resulting character is output.

Two remaining bytes: Two zero bits are appended to the second byte to form three 6-bit groups.

Base64 variants Several Base64 variants have been devised. Abhishek Rath. NoSuchMethodError: org. Regards Abhishek. Paul Clapham. I like Not directly, no. That class will be in some jar file which is independent of the JRE. If you put a jar file into this folder then it's automatically considered by the JRE to be part of the classpath any time you run a class.

This can be very convenient, except that when you upgrade to a new JRE you may have forgotten you put that jar in the Installed Extensions folder of the old JRE, or you may not have known that somebody else in your organization did that. And since the jar isn't in the Installed Extensions folder of the new JRE, suddenly things don't work right any more.

This may be what's happening to you. Tutorial here: Installed Extensions.
