How can I adb install an apk to multiple connected devices?

Question

I have 7 devices plugged into my development machine.

Normally I do adb install and can install to just a single device.

PowerShell solution

function global:adba() {
    $deviceIds = iex "adb devices" | select -skip 1 |  %{$_.Split([char]0x9)[0].Trim() } | where {$_ -ne "" }
    foreach ($deviceId in $deviceIds) {
        Echo ("--Executing on device " + $deviceId + ":---")
        iex ("adb -s $deviceId " + $args)
    }
}

Put this in your profile file (notepad $PROFILE), restart your shell and you can invoke installations with :

adba install yourApp.apk
