android mtp driver

Through the first chapter of the study, I learned a lot.Androidis a very good operating system,AndroidThe system architecture is divided into four tiers, respectively:LinuxKernel,c,c++code Base,Android SDK APIand applications. What we have to learnanrroidsystem porting is divided into two parts, application porting and system porting. But we're focusing on this part of the system transplant,AndroidThe primary work of the transplant is migration.LinuxD

Hardware Abstraction Layer: HALGoogle to join HAL for Android mainly has the following purposes:1. The calling interface of the unified hardware. Since HAL has a standard calling interface, HAL can be used to shield Linux drivers from complex, non-uniform interfaces.2. Fixed the GPL copyright issue. Because the Linux kernel is based on the GPL protocol, Android is based on the Apache Licence 2.0 protocol. S

I'll analyze the process of the local video playback in Android 4.1 on PandaBoard. Hardware acceleration for HD video playback also would be discussed.1. Video FileA video file usually contains the Part:file Header and Coded video Frames. So there is steps for video Playback:parse file header and Decode video frames. The media player must implement the functionalities. A media player consist of a media player engine and media codec plugin. The former

Android's system architecture has four layers, they are: Liunx kernel, C + + code base, Android SDK API, should program.Android is based on the Liunx kernel, so it differs from the core parts of some liunx systems even if there are differences. In this layer, Android includes liunx drivers as well as memory management, process management, power management and other programs. Where

Embedded Linux/android Drive Development Secret (1) Touch screen driver developmentSpecial Introduction: Since 1971, when American Samhurst invented the world's first touch sensor, touch-screen technology has been innovating, giving programmers and UI engineers unlimited space to imagine, which greatly improves the end user's ease of operation for a variety of devices, and now our daily lives such as mobile

Hardware Abstraction Layer:HALHAL is a set of libraries built on Linux drivers. This library is not part of the Linux kernel, but is an application that belongs to the linux kernel layer. Google joins HAL for Android to: Unify the hardware's calling interface. Solve the GPL copyright issue. For some special requirements. This chapter also describes in detail the addition of HALfor LED drivers :1. Write a procedure that supports the HAL Linux
