If port 5037 is occupied, we will be troubled by not finding the device when using the Adb command. Its function is to connect to the ADB server and provide some services for the client running on the host ДЄ small partner said that he hoped that I would put the Adb startup problem at the top, because he often encountered the problem of adb unable to find the device, then I will put it in front, I think it is definitely not only she will encounter this situation.

The program 'adbd' runs as a background process in the Android device or emulator system.

The resident process adb demon (adbd) running on the device side:.

ADB Server also needs to send the request of the adb client to the corresponding adbd via usb or tcp Its function is to detect the connection and removal of the USB port sensing device, and the start or stop of the emulator instance.

Next, when the adbd of the device and the adb server on the pc side establish a connection, the adb client can send a service request to the ADB servcer ДЄDB Server is a background process running on the host. If the ADB server cannot be found, the 'adb' program automatically starts an ADB server. First, the 'adb' program tries to locate the ADB server on the host. The command line program 'adb' is used to run adb commands from a shell or script. And what is this daemon?ДЄDB is a C/S architecture application, composed of three parts:

So there are three questions here, why is the server, the server corresponds to the server or the server? If the mobile phone is the client, does the server refer to the service opened on the computer. In order to facilitate understanding, we start with three instructions, we often use adb start-server, adb devices, adb kill-server.Д®nter fullscreen mode Exit fullscreen mode So many companies can use this feature to bypass the permission mechanism to do some operations on non-Root non-customized machines (the specific usage is mentioned below), of course, there are also various ways, such as connecting via mobile phone OTG, which will not be repeated here. Because Adb is designed to facilitate debugging by developers, it is necessary to expose some interfaces outside of permissions. In fact, Adb has a lot of authority to some extent, even on the latest version of the Android system. Many operations that hope to bypass the permission management mechanism are no longer available, but Adb can achieve it. The permission mechanism of the existing Android system is becoming more and more perfect. We can find the adb tool in the platform-tools directory of the android sdk installation directory

It can be seen that the original intention of Android is to use a tool such as adb to assist developers in debugging apk faster and better in the process of developing android applications, so adb has the ability to install and uninstall apk, copy and push files, view device hardware information, and view Functions such as applications occupying resources and executing shell commands on the device The picture below shows the official introduction of Adb by Android:

The full name of Adb is Android Debug Bridge: Android Debug Bridge. The following may be more cumbersome, I will try to be simple, please be patient and finish reading.

#Error device unauthorized adb emulator mac driver

Obviously, it is much more complicated than the driver who connects the data line and uses the adb command. It is to be installed and opened in the hands of Android developers with eclipse or other ide. When debugging the screen, it depends on whether the screen is full to verify that the driver is normal. A usage scenario of the latter makes me pay attention to him: the company customizes the Android system. The former is used to install software, and the latter is used to open the software. There are some uncommon scenarios we should at least Knowing that it can be done, for example, we know adb install but not adb shell am start. In fact, we can understand a little more. I believe that friends who do Android development have used ADB commands, but they are only limited to installing application push files and device restarting. * The content of this article is integrated from the Internet, welcome to reprint.
