Android stores and loads local files (external storage devices) and android storage devices
Sometimes the application needs to write data to the external storage of the device. If you want to share music, images, or online data with other apps or users, it is easier to share data stored on external devices. In addition, external devices usually have larger
Problem Description:
Local storage has become a growing concern in recent years in the design of virtualized architectures, where local storage costs are much lower than for Sans. Whether local storage is appropriate for your environment requires specific analysis of specific issues. This article takes only one case to help you understand the pros and cons of lo

In order to facilitate readers at different levels to understand the basic article, so I first to introduce a lot of users know things. The main function of RAM is to store code and data for the CPU to call when needed. But the data is not as simple as a bag of rice, but more like a library with a Plaid bookshelf to store books, not only to put in and to be able to make
Memory, also known as memory, is one of the important components in the computer and serves as a bridge to communicate with the CPU. All programs in the computer run in the memory, so the memory performance has a great impact on the computer. Memory (memory) is also called internal memory. It is used to temporarily store computing data in the CPU and data exchanged with external memory such as the hard disk. As long as the computer is running, the CPU transfers the data to be computed to the mem

I. The concept and development of file system and database system1. File systemThe so-called file system simply says the software structure that is responsible for accessing and managing file information. For example, the computer's hard disk C, D, E, F, and movable storage devices. A file system is a method and data structure that the operating system uses to clear files on a disk or partition, that is, the method of organizing files on disk. Also re

As a complete application, data storage operations are essential. Therefore, the Android system provides four data storage methods. They are SharePreference, SQLite, Content Provider, and File. In Android, data is basically private and stored in the "data/package name" directory. Therefore, to share data, use Content Provider.SQLite: SQLite is a lightweight database that supports basic SQL syntax and is a c
