To download the Linux kernel adapted to Android, it should be downloaded via the URL provided by Google, not just downloadable. After strictly performing the steps on the book you can download the source code for Android. By relying on the repository (. git), you can easily download the updated version of the content via Repo sync, and do not delete the. git.We can also only download part of the source code

The first chapter introduces Android Drive Development and porting technologyFirst, Android four-tier system architecture:Android 's system architecture is divided into 4 tiers, namely:Linux kernel,C + + code base, Android SDK API, application. Linux kernel: linux kernel includes Linux driver and memory management, process management, power management and other

This chapter is about setting up a test environment for s3c6410 Development Board. 1. Install Serial debugging tool: Minicom, 1th step: Use Insmod | The grep usbserial command detects whether the current system supports USB to serial port, 2nd step: Install minicom using the Apt-get install minicom command, step 3rd: Configure Minicom–s with minicom command ; 4th step: Test minicom with the minicom command 2. Burn Write Android system: (1) Use Eboot e

the IP and subnet masks using the Linux command Ifconfig, and set the gateway with the route command.This chapter only describes how to install Android on the Ok6410-a Development Board. Of course, readers can also choose other boards, or they can do Linux drivers directly on the phone. Because of the different development boards and mobile phone installation of the Android method has a certain difference,

function displays the message in the console through the/dev/console device file, which only works under the console of the character interface, so the PRINTK function is only used on the console of the character interface to output the message normally.In Linux file systems,/proc is often used as a tool for data interaction between kernel space and user space. /proc is a virtual file system, so reading and writing/proc file systems is much faster than reading/writing/dev file systems. As a res

fixed-name struct-body variable hal_module_info_sym. The HAL module consists of LEDs HAL.C and LEDs. Hal.h. Leds_hal.h header files are used to define structs, macros, and header files that reference some systems.The steps and principles for writing the HAL module are as follows: 1: Defining structs and Macros, 2: Writing the Open function of the HAL module, 3: defining Hw_module_methods_ t struct variables, 4: Defining Hal_module_info_sym variables, 5: Writing the HAL module's Close function;

to * this parameters object. * /** * OK, the wrong place. We've been positioned in a couple of places. In the code you write, check to see if you have called these methods. Android source code or gaze is clearer, look at the method in English, see if there are errors in the number of references.At that time I was using setpicturesize error, according to the method of explanation, I explained briefly. Why it went wrong. Since Parameters.setpicturesize

Objective During the Android development, I found that many An Zhouyuan code used design patterns, more commonly used adapter patterns (various adapter), Builder Mode (Alert dialog build), and so on. Although we know a lot about design patterns, in this aspect of applying design patterns, it feels like many people are lacking in this. So this article is a deep understanding of the builder model in

Android audio and video went deep into 1949th using ijkplayer as a video player (with source code download) and androiw.player Project addressHttps://github.com/979451341/MyijkplayerSome time ago, I thought it was difficult to make FFmpeg a video player. Although there was no problem in playing the video, I still needed to drag the progress bar to set the playing progress, that can be postponed .....Now let

/*/kernel directory.LIB: library file code.MM: Memory management code, and part of the platform-related code is placed in the ARCH/*/MM directory.NET: Network-related code, the realization of a variety of common network protocols.Scripts: The script file used to configure the kernel.5, Android Transplant is mainly the Linux kernel transplant, the Linux kernel transplant is mainly Linux4-Driven porting. So we need to build two sets of environments for

) before the Android burning, be sure to start the Eboot erase Nandflash, using the Eboot erase steps as follows: Preparation, with the serial cable or USB to the serial port to connect the development Board and the PC, and start the minicom, enter the Eboot state, open the Development Board power switch, Initiating launch in 5 seconds. Tip, press the SPACEBAR on the PC keyboard to stop the Development Board in the Eboot state. Erase Nandflash Enter "

to put the business logic into the HAL Library . Step 2 : Write HALThe HAL library is an ordinary Linux Library (*.so ) file. However, this type of library file has an interface. The SYM variable is module_info through the HAL. Service Library is defined in this interface by the ID positioning hallibrary the. Step 3 : Write the Service LibraryAlthough this step is not required, the new HAL architecture requires us to do so. the Service library is also a Linux library . This step is more flexib

Android Deep Exploration (Vol. 1) HAL and Driver development experienceThe tenth chapter of embedded Linux call technologyFor complex Linux drivers and libraries such as HAL, you need to debug them in a variety of ways. For example, set breakpoints, step through code, output debugging information, and so on. While embedded Linux is not easy to debug with visual Studio, Delphi, Eclipse visualization tools, l

By learning Android Deep Exploration (Volume one) HAL and driver development in the seventh chapter let me know how to control the light emitting diode through the driver, realize the driver directly interacts with the hardware.A complete Linux driver mainly consists of internal processing and hardware interaction, in which the internal processing mainly refers to the Linux driver loading, unloading, device

wrong place, we are positioned in such a few places. In the code you write, check to see if you have called these methods. Android source code is still more clearly annotated, see the method in English, see if there are errors in the parameters.At that time I was using setpicturesize error, according to the method, I explained briefly, why the error. Because Parameters.setpicturesize (320, 480) (set resolution) parameter is wrong, if you do not know

Accessibility design for Android embedded configuration software: When compiling on the menu bar, it is used to display the results of the compilation. Includes features such as root layout, screen resolution, editing, and deletion. The

Hal is a set of libraries built on Linux drivers. This library is not part of the Linux kernel but is the application layer on top of the Linux kernel layer.Google's main purpose for adding Hal to Android is as follows:1, the unified hardware call interface.2, solve the GPL copyright issue.3, for a number of special requirements.To write a Linux driver that supports HAL:1. Write Linux drivers2. Writing Hal Library3. Write Service LibrarySteps and prin
