Android Debug Bridge helper written in Kotlin

Get started now View it on GitHub


The only way to get access to the adb programmatically from java world currently is to use the ddmlib java project. Unfortunately it has several limitations, namely:

  1. Sub-optimal resources usage
  2. Code is not tested properly
  3. Limitations of adb server are propagated to the user of ddmlib

To optimize the resources usage adam uses coroutines instead of blocking threads. This reduced the load dramatically for scenarios where dozens of devices are connected and are communicated with. Full E2E testing with at least Android emulator is also used to guarantee stability.

Supported functionality

  • Shell
    • Basic shell: support (with stdout and patched exit code)

Getting started

Maven Central

To add a dependency on Adam using Maven, use the following:


To add a dependency using Gradle:

dependencies {
  implementation 'com.malinskiy:adam:X.X.X'

Basic usage example

//Start the adb server

//Create adb client
val adb = AndroidDebugBridgeClientFactory().build()

//Execute a request
val output = adb.execute(ShellCommandRequest("echo hello"), "emulator-5554")
println(output) // hello
