OTG cable – Make sure that your device supports OTG.Preparations and Downloadsīefore you can use your Android phone or tablet device as a PC for running and executing ADB and Fastboot commands, you will require a few things (Search “adb” in / system/bin or /system/xbin folder. This file is already included in some new devices. Thanks to Google, ADB has been compiled for ARM. We can’t use them because those files are not compiled for ARM. You may think that we can use ADB and fastboot binary files for Linux on our Android devices. This guide here will show you how to install ADB and Fastboot on any Android smartphone or tablet, so can perform all the activities you would on your PC. But let’s say that your PC isn’t working or maybe you are traveling and the PC available doesn’t have ADB/Fastboot installed. There are certain devices out there that don’t support the traditional custom recovery flashing methods instead you have to use ADB and Fastboot to flash the files. One of the main advantages of using ADB or fastboot in you can install system updates, custom ROMs, boot images, custom kernel, and applications as well. And without them, it’s impossible to perform any sort of development on your phone. Learn how you can execute ADB and Fastboot command on Android phones and tablet devices.ĪDB and Fastboot have become essential tools for every developer and advanced Android user nowadays. You can flash a device when it's in the fastboot bootloader mode.Here’s how you can use Android device as PC for ADB and Fastboot. Not all Android devices have fastboot enabled.Īndroid device manufacturers are allowed to choose if they want to implement fastboot or some other protocol. Fastboot does not require USB debugging to be enabled on the device. Fastboot allows to boot from a custom recovery image. If the mode is enabled, it will accept a specific set of commands sent to it via USB using a command line. It requires that the device be started in Fastboot mode. It is included with the Android SDK package used primarily to modify the flash filesystem via a USB connection from a host computer. It is implemented in a command-line interface tool of the same name and as a mode of the bootloader of Android devices. Communication with a device is done with a Transport.įastboot is a communication protocol used primarily with Android devices. On the other side, the Server continuously monitors for connecting Daemons (as USB devices or TCP emulator). On one side the Server exposes a “Smart Socket” to Clients such as adb or DDMLIB. The central part is the Server which runs on the Host computer. Three components of adb pipeline: As outlined in the overview, this codebase generates three components (Client, Server (a.k.a Host), and Daemon (a.k.a adbd)). this makes distribution and starting the server easier.ģ. Currently, a single 'adb' binary is used for both the server and client. Then, the client sends its service requests to the ADB server. It first tries to locate the ADB server on the host machine, and will start one automatically if none is found. ADB command-line client: The 'adb' command-line program is used to run adb commands from a shell or a script. The BOOTLOADER and RECOVERY states correspond to alternate states of devices when they are in the bootloader or recovery mode.ģ. Otherwise, the device is OFFLINE, meaning that the ADB server detected a new device/emulator, but could not connect to the adbd daemon. The ADB server considers that a device is ONLINE when it has successfully connected to the adbd program within it. Its purpose is to connect to the ADB server (through USB for devices, through TCP for emulators) and provide a few services for clients that run on the host. ADB daemon (adbd): The 'adbd' program runs as a background process within an Android device or emulated system. The ADB server is really one giant multiplexing loop whose purpose is to orchestrate the exchange of data (packets, really) between clients, services and devices.Ģ. It thus maintains a list of "connected devices" and assigns a 'state' to each one of them: OFFLINE, BOOTLOADER, RECOVERY or ONLINE. Its purpose is to sense the USB ports to know when devices are attached/removed, as well as when emulator instances start/stop. ADB server : This is a background process that runs on the host machine.
