1# String Encoding and Decoding 2 3### Introduction 4 5This sample shows how to output strings in a specified format and obtain error messages corresponding to error codes. It also demonstrates string encoding and decoding. The sample app is as follows. 6 7 8 9### Functions 10 111. Output in a specified format: You can use the app to output a string in different formats. 12 132. Error code parsing: You can input an error code in the app to obtain the corresponding error message. 14 153. Text encoding and decoding: You can use the app to encode and decode strings. 16 17### Required Permissions 18 19N/A 20 21### Usage 22 231. Touch **Output in specified format**. Your input is then displayed in different formats, such as integer, floating point number, and string. 24 252. Touch **Obtain error details**. The error message corresponding to the error code is displayed in the text box on each line. 26 273. Touch **Text encoder**. Your input is then encoded and displayed, together with the information about data reading and writing. 28 294. Touch **Text decoder**. The encoded text content is decoded, and the output displayed is the same as what you input. 30 31### Constraints 32 331. This sample can only be run on standard-system devices. 34 352.
