Android implements SD card and memory file storage in the same way. The method for obtaining the file path is basically the same as that of java. The following is the code of the program. The configuration location and implementation are different. Others are the same. The following code is used: Main. xml: [Html]Android: orientation = "vertical"Android: layout_w

Usage scenarios:1. When copying files, it is common for a thread to call an interface to copy files, which requires caching the data, and if each file needs to create a separate cache, the memory fragmentation is large.If you create a static memory area, when multithreading calls the same interface, multiple threads using the same static cache can cause data pollution. The best way is that the cache is visible only to this thread,Creates a buffer when

The naming method for Pg XLOG files (REDOLOG) names is defined in the XLogFileName macro, the time series ID, log ID, and segment ID are composed of eight hexadecimal numbers. For example, 000000000000000000008f. # Define XLogFileName(Fname, tli, log, seg)\ Snprintf (fname, MAXFNAMELEN,"% 08X % 08X % 08X", Tli, log, seg) Different segment IDs correspond to different physical XLOG log files. Log IDs are logical concepts and contain multiple physical XLOG files. The initial size of the Pg XLOG

context.mode_private: Is the default mode of operation, which means that the file is private data and can only be accessed by the app itself , in which the contents of the original file are overwritten by the written content . If you want to append the newly written content to the original file. You can use Context.mode_appendcontext.mode_append: The mode checks

, you can directly check the file extension, as long as the file extension is satisfied, so that the file can be stored. In any case, the execution permission restriction is imposed, and it is okay if you do not store the content as required. It cannot be executed.Correct steps:1. Read the file name and verify that the
