1. Configuration File
In the Android system, there are some Initialization Configuration files, such:
/Init. RC/Default. Prop/system/build. Prop
The file contains the system attribute values configured for the boot settings. These attribute values can be obtained through getprop and set by setprop, such:
1. Start emulator (simulator)Enter emulator in DOS and press enter to start emulator, provided that you add the tools directory of the android SDK to the environment variable; otherwise, you must first enter the tools directory of the android SDK, then enter the emulator command. 2.

In Linux, when debugging Android phones on a real machine, you often encounter insufficient permissions for device errors. In addition, ADB devices may be garbled and you are not authorized to perform any ADB operations. The following configuration method can solve this problem (the environment is UBUNTU ):
1. Enter terminal
For complex Linux drivers and libraries such as HAL, you need to test them in a variety of ways. such as setting breakpoints, gradually tracking code, output debugging information and so on. This chapter focuses on how to debug embedded Linux kernel modules, executable programs, and shared libraries using the Development Board, Android emulator, and some function

For female programmers, every time they install software or configure an environment, they often crash. This is also true for Aunt ape ~ (Ah, do I say I'm an aunt ?)

Adding a driver to the android kernel is actually adding a driver to the Linux kernel. It mainly adds vertex information to two files, one is the kconfig file and the other is the MAKEFILE file. For example, if the driver you added is placed in the xxx directory under the DRIVERS directory, the kconfig and makefile files under the directory will be repaired.
Specific modification method:
For example, I want

Because in Android do serial driver Dongdong, so to install ndk, used to be VMWARE-6.5.1 + fedora10 development environment.Therefore, we re-built a virtual machine based on the original vmware6.5 + fdeora10, and created wins. After the Linux File is switched, We decompress all ndk, SDK, eclipse, and JDK to OPT.
Configure the environment variable. I added the export path to VIM/etc/profile and added the JDK
Step 1:Linux Bash support for Windows 10 is not implemented with virtual machines/emulators, but is embedded in a complete Ubuntu Linux environment. It is technically a system call that transforms Linux system calls into Windows in real time, and you can think of it as Wine as a reverse technique. Microsoft calls it the Linux

A. Use the adb LAN function to connect the device
1. Run the adb command with a usb connection and change the connection mode to tcpip.Adb tcpip {port} port is the port number2. Unplug the USB cable and run the adb command to connect to the device.Adb connect xxx. xxx (device ip): port (the port number just set)3. Run the adb command normally.Adb works in a special way by listening to Socket TCP 5554 and other ports to allow the IDE to communicate with Qemu. By default, adb will use the network
