Android Base64 Encryption decryption

Encrypted incoming data is of type Byte, not using the Decode method to convert raw data to binary, string type of data using Str.getbytes () can be string str = "hello!"; /Here is the Encode method, which returns a byte type of encrypted data, which can be converted to String type string strBase64 = new string using the new string (Base64.encode (Str.getbytes (), Base64.default)); LOG.I ("Test", "encode >>>" + strBase64);//Here Encodetostring directly returns the string type of encrypted data string entostr = Base64.encodetostring (Str.getbytes (), base64.default); LOG.I ("Test", "encodetostring >>>" + entostr);//Decrypt data after Base64 encryption LOG.I ("test", "Decode >>>" + new STR ING (Base64.decode (strbase64.getbytes (), Base64.default));
