SQLite is a little different from other common database, that is, the SQLite database is stored in a file, you can directly export the file from the phone, as a file, and then put on the computer to view.The Android operations database has the following steps:1, inherit Sqliteopenhelper, realize the method inside.Publicclassmydbhelperextendssqliteopenhelper{publi

Android apps will inevitably deal with SQLite. With the continuous upgrade of the application, the original database structure may no longer adapt to the new features, this time, you need to upgrade the structure of the SQLite database. SQLite provides ALTER TABLE commands that allow users to rename or add new fields

Android provides four Data Storage Methods: Shared preferences: used to store data in the "key"-"value" format. It is a lightweight key-value storage mechanism, only basic data types can be stored. Filws: file storage SQLite: a standard database provided by Android. Supports SQL statement Network: stores and obtains data through the network.Shared preferences is

Introduce the encryption module to SQLite in the Android JNI Environment Free SQLite Open Source Code provides only two functions. Only these two functions can achieve the overall database encryption. Then waste a little effort from the Internet to find a good open source library http://sourceforge.net/projects/wxcode/files/Components/wxSQLite3/ has been achieved

Recently I am looking at the source code of the Android platform. Next I will summarize the relationship between sqlitedatabase and its underlying sqllite database. How does the upper-layer sqlitedatabase call the underlying SQLite database operation. Sqlitedatabase is a class used by the android framework layer to encapsulate sqllite database operations. Apps c

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/data/package name" directory. Therefore, to share data, use content provider.
