How to determine files? You can use Cursor to traverse the database and compare the value of the INTERNAL_CONTENT_URI field. This is a Uri, which stores the complete path of the multimedia file on the Android mobile phone SD card. [Java] Copy codeThe Code is as follows: Uri originalUri = MediaStore. Images. Media. EXTERNAL_CONTENT_URI; // If it is a Video, it is MediaStore. Video. Media. EXTERNAL_CONTENT_UR

When the Android system is started, it will automatically detect the SD card files and collect music files to generate a database file.

Recently I made an android music player. I personally felt that the most difficult part was "playing back" and "playing list", but I finally found the implementation method. Different people may implement different methods. Here I will share some of my implementation methods for the "playlist" module. "playing back" will be introduced in the next blog, I hope you can share some of your ideas. Android uses ContentProvider to support data sharing between different applications. To facilitate opera
