The previous blog post made a series of analyses on Lichee, which is actually a basic quality of Android BSP-SHELL script, as described in seven years itch, therefore, the Lichee series focuses on the basic structure of SHELL scripts and Lichee. Of course, as a qualified Android BSP engineer, we master the Linux driver porting, it is also a basic skill. So from t

The ultimate goal of Android transplant development is to develop mobile phone products. From the developer's point of view, this type of development is based on the hardware system, and builds the Android software system. This type of development works at the bottom of the Android system.In terms of software systems, the main work is focused on the following two

Android developed very quickly in the 21st century, with a large share of the market, far ahead of iOS, largely because anyone could use Android's source code to customize the embedded development system entirely, without having to pay Google a penny.With the rapid development of the communications and electronics industries, a large number of new chips are produced every day, and a large number of new boards are designed, so there will also be a larg

The previous blog post to Lichee did a series of analysis, in fact, in the "Seven itch," said, Android BSP has a basic quality-shell script, so we Lichee series of articles focused on the shell script and lichee the basic structure, Of course, as a qualified Android BSP engineer, mastering the Linux driver porting is also a basic skill. As a result, some of the d

Android is essentially a Linux kernel based system, which means Android is a Linux operating system. But most of the time it will run on arm-architecture devices, such as Android phones, tablets, and so on. Android drives are actually Linux drivers, but here's Android Deep E

First we give the following parameters, which are to be used later:10 Android Old driver teaches you to create a unique refresh loading frameworkSince it is refreshing, our scrolling must be before the parent view. So we need to write the x, y values that we need to change in the Onnestedprescroll method.We need to use the parent view to intercept it. We need to determine if the value of DY is greater than

1. We are on the desktop of the computer right click on the desktop "computer/My Computer" and then click "Manage" in the pop-up menu as shown in the picture. 2. Then in the pop-up menu we click "Management" in the "Device Manager" shown in the following image. 3. Then we found "ADB Interface" or "Android Phone" devices in "Device Manager", which are usually shown in the first device. If the driver is

the application can read sequentially and does not normally support random access. Such devices run in bytes/characters to read and write data, modem is the character deviceBlock device: The application can randomly access the device data, and the program can determine where to read the data at its own discretion. HardwareIf you're using an original Linux OS as a base for Android, the job is simply to add drivers for Android.Android's Ril (Radio Inte

With the current variety of systems, competing for development, the market share of the Android system is far ahead of other systems, in order to enable the perfect operation of Android on a variety of devices, we can learn Linux-based Android Drive development and porting, This chapter of Linux and Android to make a c

In the previous article, we described how to write Linux kernel drivers for the Android system on Ubuntu. In this Linux kernel driver named Hello, three different file nodes are created for user space access, traditional device file/dev/hello, proc system file/proc/hello and DEVFS System Properties file/sys/class/ Hello/hello/val. Further, the/proc/hello and/sys/class/hello/hello/val files are accessed dire

Android has a complete display system. The upper-layer display system provides output devices for system graphics. the Java layer and controls are displayed by the display system. The underlying Display System of Android has a strong relationship with the surface library of Android. The underlying display system provides encapsulation of basic display and output

In the context of the Ubuntu Android simple introduction to the Hardware Abstraction layer (HAL), we briefly describe the way in which the Android system writes drivers for the hardware. In simple terms, the hardware drivers are distributed in the Linux kernel and distributed in the hardware abstraction layer of the user space on the other hand. Then the Linux kernel dr
