Android Debug Bridge: Android Debug Bridge (adb) is a command line tool that lets you communicate with an emulator or connected Android device. It is a client-server program that includes three components: • Client- It runs on your development machine. You can invoke a client from a shell by issuing an adb command. • Server-It runs as a background process on your development machine. The server manages communication between the client and the adb daemon. • Daemon- It runs as a background process on each emulator or device instance. ADB is found as part of the Andriod SDk Platform-tools package, it consists of both client and server-side programs that communicate with one another.When you start an adb client, first checks whether there is an adb server process already running.

If there is no adb running process, it starts the server process. When server starts, it binds to local TCP port and listens the adb commands. The server then sets up connections to all running emulator/device instances. It locates emulator/device instances by scanning odd-numbered ports in the range 5555 to 5585, the range used by emulators/devices. Where the server finds an adb daemon, it sets up a connection to that port. ADB Commands: The format for issuing commands through the ADB is as follows: adb [-d -e -s ] Installing an Application: With the help of adb we can install our app on emulator or device.

Adb install where is the path of that apk file which you want to install on emulator/device. Viewing connected Android devices: To view the attached devices use devices command. It prints a list of all attached emulator/device instances.

The secure adb intoduced in 4.2/4.3 doesn't always work with older ones. I had the same issue a few weeks ago. If this doesn't work under developer options hit revoke usb debugging authorizations and try connecting it again. Sep 23, 2011 - Save restartADB.bat file. If you want restart adb.exe server, run restartADB.bat by double click on icon. Next example: Open Total Commander.

Adb devices Here’s an example showing the devices command and its output: $ adb devices List of devices attached emulator-5554 device emulator-5556 device emulator-5558 device where emulator-5558 is the serial number and device is the instance that is connected to adb server. If there is no emulator/device running, adb returns no device. Sending commands to specific emulator/device: If multiple emulator/device instances are running, you need to specify a target instance when issuing adb commands. Adb -s Example: adb -s emulator-5556 install demo1.apk Copying Files to or from an Emulator/Device: You can use the adb commands pull and push to copy files to and from an emulator/device. If you want to copy a file from the emulator or device you can use pull command. Adb pull If you want to copy a file to the emulator or device you can use push command.
