Android data cache-file storage, android file storage
During Android APP development, we usually add cache modules. Cache stores some APP data locally. Most of the data requested by the network is stored locally, so that the cached data can be directly used within the cache data validity period, this reduces the pressure on apps and servers and greatly improves user experience. Android data cache can be sa

Linear table-sequential Storage Structure and linear Storage Structure
1) Statement
Newbie. If something is wrong, unreasonable, encoding style, and algorithm ideas need to be improved, please give me some advice.
Ii) Introduction
This article uses the method of dynamically opening up the memory to create a linear table, to achieve the basic operations of the sequence table.
This code is simple. After all,
context.mode_private: Is the default mode of operation, which means that the file is private data and can only be accessed by the app itself , in which the contents of the original file are overwritten by the written content . If you want to append the newly written content to the original file. You can use Context.mode_appendcontext.mode_append: The mode checks whether the file exists, appends content to the file, or creates a new file.context.mode_world_readable and context.mode_world_writeab
We know that there are common file name detection vulnerabilities and file format check vulnerabilities. Another vulnerability is the file storage vulnerability. this vulnerability mainly allows users to read input path names and use incorrect filtering methods, leading to malicious users, storing files in unexpected locations poses security risks.
As a matter of fact, let's take a few points. let's take a look at it first. since the user wants to st
Attribute list of iOS data persistent storage, ios Data StorageProperty list (plist)
IOS provides a plist format file (attribute list) for storing lightweight data. It can only store data of the NSDictionary, NSArray, NSString, NSNumber, Boolean, NSData, and NSDate types. Save these types of data as plist files. The stored data can be directly read using NSDictionary and NSArray.

Next, let's take a look at the NSU

Read the last two articles. We know that there are common file name detection vulnerabilities and file format check vulnerabilities. There is also a file storage vulnerability. This type of vulnerability mainly allows users to read the input path name and use incorrect filtering methods. As a result, malicious users can store files in unexpected places, posing a security risk.

Data storage (2) -- XML storage of the SAX engine (with Demo)
The Android SDK only supports reading XML using the SAX technology, and the SAX adopts the sequential reading method to process XML documents. This requires that each time you read a node of the XML document, the corresponding event is triggered to process the node. The following describes how to use SAX based on an instance:
