Intent and usage of open file for Android programming development

This paper describes the intent and use method of opening files in Android programming development. Share with you for your reference, as follows:

When writing the file management system, various requirements for opening files in different formats will be used. Because Android system has built-in system applications that can be opened by default, it still can not meet the requirements, such as opening video files, word, etc., which can only be used after installing corresponding playback software, At this time, the program will find the software that can be used through intent. Opening a file through code requires two parts. One part is to obtain the suffixes of different files to match the corresponding intent according to the demand, and the other is that the open intent of files with different formats is different

1. Define the suffix array file fileendings in the values directory

2. Define the openfiles tool class, just transfer the file parameter, and then open the file through the returned intent

3. Defines the suffix used to check whether the file to be opened is in the traversal suffix array

4. Open the corresponding file by calling the intent returned by the openfiles class

I hope this article will help you in Android programming.
