PrefaceUnconsciously the Android Basic series has written 13, this is the 14th article ~ the previous blog recorded a data storage program in Android, That is, the use of shared parameters (Sharedpreferences) (Virgin Male Learning Android (13)---Android Lightweight data storage sharedpreferences). Recently how to learn

Preface SQLite is a lightweight small database. Although it is relatively small, it has relatively complete functions, and some common basic functions of databases are also available, in the current embedded system, this database is used a lot because it occupies a small amount of system resources. SQLite is also used in the Android system. This section describ

Objective: In addition to landing in the project, payment and other interfaces using RSA asymmetric encryption, outside the use of AES symmetric encryption, today we come to understand the AES encryption. Several other encryption methods:RSA encryption of

SQLite Introduction SQLite is a very popular embedded database. It supports the SQL language and has good performance only with a small amount of memory. In addition, it is open-source and can be used by anyone. Many open-source projects (Mozilla, PHP, Python) Use SQLite. SQLite consists of the following components: SQ

Simple use of SQLite databases in Android File file = new File(“hah.txt "); // Only an object file is created. The filepath refers to the hah.txtfile. The hah.txt file may or may not exist. If the file does not exist, it will not be created. Only when a file output stream writes the file can the file be created. Cursor: When you access a table structure in a database and want to access a row in the table,

Android DES encryption related implementation, a simple implementation of a moment, today to sum up: DES encryption Introduction:des is a symmetric encryption algorithm, the so-called symmetric encryption algorithm is: Encryption

Last time I introduced you to the basic information and usage process of SQLite. I believe my friends have some knowledge about SQLite. Today, I will share with you how to use SQLite in Android. Currently, mainstream mobile devices such as Android and iPhone all use

[Android development experience] a safer algorithm than DES encryption-3DES encryption algorithm, android3des Reprinted please indicate the source: http://blog.csdn.net/zhaokaiqiang1992 In the previous article, we discussed the DES algorithm and learned how to ensure the consistency of encryption and decryption results

similar to tables in a database, that is, contentprovider is like a "Database ". The data provided by the outside world should be basically the same as the data obtained from the database, except that the URI is used to indicate the "Database" that the outside world needs to access ". As for how to identify which database is needed from the URI, this is what the android underlying layer needs to do. In brief analysis, contentprovider provides externa

Hi everyone! Today we will focus on the usage of SQLite in Android. Easy: The office room and the programmer in the office room;Programmers write programs and exchange wine with the program.When you wake up, you just sit online and get drunk and stay asleep;Drunk wine wake up day after day, online next year after year.I hope the computer room will never bow to the boss;Mercedes Benz and BMW are fun and prog

A brief introduction SQLite is a lightweight, cross-platform, open-source database engine that has the advantage of read-write efficiency, total resource consumption, latency, and overall simplicity, making it the best solution for mobile platform databases (such as Android, IOS). The Android system has a built-in SQLite
