Embodiment

[0043] The short message database includes a public short message database and an encrypted short message database. Among them, the public short message database is the main database, and the encrypted short message database is the secondary database. The ID range [10001,20000] of the encrypted message database, the specific implementation is as follows:

[0044] Step 1. Construct the access architecture of SMS master content provider-SMS slave content provider on the Android terminal;

[0045] Step 1-1. Construct SMSContentProvider, the main content provider of SMS. Directly inherit the original Android content provider to generate the SMS main content provider. The SMS main content provider has all the interfaces and functions of the original Android content provider, including data query interface, data insertion interface, data update interface and data deletion interface.

[0046] Step 1-2. Build the SMS slave content provider SMSSlaveContentProvider. The SMS slave conte...

Abstract

The invention relates to a multi database visiting method based on an Android terminal. The multi database visiting method based on the Android terminal comprises the following steps: firstly, establishing a visiting framework which both a main-content provider and a following content provider are coexisted on the Android terminal; secondly, respectively connecting a plurality of databases with identical database table structures on the main content provider and the following content provider in a hanging way, and enabling the main content provider and the following content provider to operate corresponding databases; and finally, the main content provider and the following content provider achieve visit of the plurality of databases at the same time based on the call request of an application program. By establishing the visiting framework of the main content provider and the following content provider, the multi database visiting method based on the Android terminal simplifies a complex process flow of an original content provider to the plurality of databases as visiting and improves process efficiency.

Description

technical field [0001] The invention belongs to the field of intelligent handheld terminal operating systems, in particular to an Android terminal-based multi-database access method. Background technique [0002] Android is a well-structured hierarchical software and hardware platform, which can be divided into four layers: the top layer is the application program layer, which is provided by operating system manufacturers or third-party developers with multiple functional applications; the second layer is the application framework layer, Provides the Java layer framework for application running and necessary basic services, etc.; the third layer is the system runtime layer, which provides system libraries and Android runtime libraries; the bottom layer is the Linux kernel layer, which provides the necessary operating system kernel drivers and hardware drivers . Among them, the application framework layer is the basis for application development. It provides rich API interfa...
