Blog Post: Our First Open-Source Project
A Kotlin/Java library to connect directly to an Android device without an adb binary or an ADB server
dependencies {
implementation("dev.mobile:dadb:<version>")
}Connect to emulator-5554 and install apkFile:
Dadb.create("localhost", 5555).use { dadb ->
dadb.install(apkFile)
}Note: Connect to the odd adb daemon port (5555), not the even emulator console port (5554)
The following discovers and returns a connected device or emulator. If there are multiple it returns the first one found.
val dadb = Dadb.discover()
if (dadb == null) throw RuntimeException("No adb device found")Use the following API if you want to list all available devices:
val dadbs = Dadb.list()Prerequisite: Connecting to a physical device requires a running adb server. In most cases, this means that you must have the adb binary installed on your machine.
The Dadb.discover() and Dadb.list() methods now both support USB-connected devices.
// Both of these will include any USB-connected devices if they are available
val dadb = Dadb.discover()
val dadbs = Dadb.list()If you'd like to connect directly to a physical device via its serial number. Use the following API:
val dadb = AdbServer.createDadb(
adbServerHost = "localhost",
adbServerPort = 5037,
deviceQuery = "host:transport:${serialNumber}"
)dadb.install(exampleApkFile)
dadb.uninstall("com.example.app")dadb.push(srcFile, "/data/local/tmp/dst.txt")
dadb.pull(dstFile, "/data/local/tmp/src.txt")val response = dadb.shell("echo hello")
assert(response.exitCode == 0)
assert(response.output == "hello\n")dadb.tcpForward(
hostPort = 7001,
targetPort = 7001
).use {
// localhost:7001 is now forwarded to device's 7001 port
// Do operations that depend on port forwarding
}Dadb will use your adb key at ~/.android/adbkey by default. If none exists at this location, private and public keys will be generated by dadb.
If you need to specify a custom path to your adb key, use the optional keyPair argument:
val adbKeyPair = AdbKeyPair.read(privateKeyFile, publicKeyFile)
Dadb.create("localhost", 5555, adbKeyPair)Copyright (c) 2021 mobile.dev inc.
