I'm on a problem by taking the selected gallery picture and want to save it first as Base64 String in a XML file for later use. For example if you exit the app and open it again. I tried to use Base64InputStream but without success.

Can you give me a hint how to get from InputStream to Base64 String? Also don't forget to add permissions in AndroidManifest. Got this code from something I use in an application, stripped it down to the most basic as far as i know.

If you are selecting image from Gallery then why you are saving it as Base64 string in xml fileyou can reuse that image from gallery. If you want to store it locally then you can use SQLite Database to store itfor more detail visit this link.

String to base64 converter options Base64 Chunks Enable Base64 Chunks Split base64 output into lines with a constant size. Chunk length Output line length. Output Base64 As Is Disable base64 chunks and print output as a continuous stream of text. String to base64 converter tool What is a string to base64 converter? This tool converts a plain string to base64 encoding.

Base64 encoding uses only letters a-z, A-Z, and plus, slash and equals sign characters. This encoding scheme takes every 6 bits of the input string and assigns one of 64 letters to it.

It's easy to calculate that base64 produces a larger output than the original string. In the options above, you can also set base64 encoding's output chunk size line length. And coming soon, you'll be able to customize 63rd plus and 64th slash alphabet characters as well as change the padding character.

There is a way to convert inputStream to a String, and encode it to base64, right? Is there a way to do that? The simplest way would be to use IOUtils from apache-commons to do that:. You can do that directly using JDBC:. As I mentioned, you shouldn't use String for binary data. The baseencoded data can be stored as a String though.

But since your database column is a blob, I would continue to work with a byte[]. Then write it to the database. Writing a blob using jdbc and a PreparedStatement looks like this:. Learn more.

Convert a hexidecimal string generated by toHexString back into a byte array. Convert a string into a byte array in hex format.Converts the value of an array of 8-bit unsigned integers to its equivalent string representation that is encoded with base digits. Converts a subset of an array of 8-bit unsigned integers to its equivalent string representation that is encoded with base digits.

Parameters specify the subset as an offset in the input array, the number of elements in the array to convert, and whether to insert line breaks in the return value. Parameters specify the subset as an offset in the input array, and the number of elements in the array to convert. Converts an array of 8-bit unsigned integers to its equivalent string representation that is encoded with base digits.

You can specify whether to insert line breaks in the return value.

Converts the 8-bit unsigned integers inside the specified read-only span into their equivalent string representation that is encoded with base digits. You can optionally specify whether to insert line breaks in the return value. InsertLineBreaks to insert a line break every 76 characters, or None to not insert line breaks.

The string representation in base 64 of length elements of inArraystarting at position offset. The following example demonstrates the ToBase64String method. The input is divided into groups of three bytes 24 bits each. Consequently, each group consists of four 6-bit numbers where each number ranges from decimal 0 to In this example, there are 85 3-byte groups with one byte remaining. The first group consists of the hexadecimal values 00, 01, and 02, which yield four 6-bit values equal to decimal 0, 0, 4, and 2.

Those four values correspond to the base digits "A", "A", "E", and "C" at the beginning of the output. If an integral number of 3-byte groups does not exist, the remaining bytes are effectively padded with zeros to form a complete group.

In this example, the value of the last byte is hexadecimal FF. The elements of the inArray parameter are taken as a numeric value and converted to a string representation in base The offset and length parameters are bit signed numbers. The offset parameter is zero-based. The ToBase64String method is designed to process a single byte array that contains all the data to be encoded. To encode data from a stream, use the System.

ToBase64Transform class. If the options parameter is set to InsertLineBreaks and the output of the conversion is longer than 76 characters, a line break is inserted every 76 characters.
