Android MediaScanner Summary

Android MediaScanner Summary
1. Introduction

Since then, the source code analysis of Android MediaScanner has been completed, and it has been written intermittently for more than half a month. Now let's summarize MediaScanner. (The overall architecture of MediaScanner is still referenced in the general outline of Android MediaScanner)

2. Programmatic articles

Android MediaScanner Overview
This article describes the MediaScanner architecture in detail, including the MediaScanner system hierarchy, the involved code, and the call sequence. You can see several figures in detail.
To understand the overall structure of MediaScanner, you must first read this article.

3. Each module analyzes the 3.1 APP Layer

Android MediaScannerService source code analysis

3.2 communication layer

Android MediaScanner source code parsing
Android MediaScannerJNI source code
One JAVA and one C ++ are responsible for upward and downward communication. By checking the code, you can find that there is a MediaScannerClient. It is estimated that Google's original design idea is to map the two, but it only implements some of them, the Client at the C ++ layer is hardly implemented.
