There are two ways to access images in an Android database, one is to save the path to the image, and the other is to store the image in binary form (Sqlite3 supports BLOB data types). For the use of the two methods, as if the second method than the first method is more popular with programmers, they think, in many database languages, the processing of large segments is not easy, such as pictures of

hardware services for the Java interface on the application frameworks layer of the Android system.I. Refer to the article on the Java Access Hardware service interface in Ubuntu for authoring the Jni method for the Android hardware Abstraction Layer (HAL) module, and prepare the JNI method call layer for the hardware Abstraction Layer module.Two. In

storage space is very large, such as 16g or 32g, where 16g and 32g refers to the total size of the disk, the equivalent of your newly-bought computer a new hard disk. When the phone comes out of the factory, it will burn Android on this disk, the Android system will partition the entire disk, part of the Android system can be used to store system

Android is a multi-process system in which the application (or part of the system) runs in its own process. The security between the system and the application is enforced at the process level through the Linux facilities (tools, functions), such as assigning the user ID and group ID to the application. A more granular security feature is the "Permission" mechanism to restrict specific actions for a particular process, while "Per-uri permissions" can

In the Android Hardware Abstraction Layer (HAL) Overview and Learning Plan article, we briefly describe the ways in which Android systems write drivers for hardware. In short, hardware drivers are distributed on the Linux kernel, and on the other hand, in the hardware abstraction layer of user space. Next, writing a Linux kernel driver for Android on Ubuntu cited

[Android development experience] What Should cached files of an APP exist? After reading this article, you should be clear about it. androidapp Reprinted please indicate the source: http://blog.csdn.net/zhaokaiqiang1992 As long as it is an APP that requires online data retrieval, cache files will be generated locally, regardless of version update or image cache.

Android uses Io streams to read and write files in the same way as javase. In addition, Android uses the javase Io stream. Next we will use an exercise to learn how to read and write Android files. 1. Create an android Project P

export the file by clicking on the "Floppy left arrow" icon in the upper right corner of File explorer. The first parameter of the Openfileoutput () method specifies the file name, cannot contain the path delimiter "/", and if the file does not exist, Android automatically creates it. The created file is saved in the/data/data/ If the file is too large to be stored on the phone's file directory, it needs to be stored on sdcard. Use the activity of th
