Can you deploy to a device via Gradle from the command line

Question

What the question says really - can you issue any commands directly to gradlew via the command line to build, package and deploy to a device?

Answer 1

A more flexible way to do it is by using monkey:

task runDebug (type: Exec, dependsOn: 'installDebug') {
    commandLine android.getAdbExe().toString(), "shell",
        "monkey",
        "-p", "your.package.name.debugsuffix",
        "-c", "android.intent.category.LAUNCHER", "1"
}

Some advantages to this method:

• getAdbExe doesn't require adb to be on the path and uses the adb version from the sdk pointed to in local.properties.
• The monkey tool allows you to send a launcher intent, so you aren't required to know the name of your activity.

Answer 2

One line sentence:

Build project & Install generated apk & Open app on device

$ ./gradlew installDebug && adb shell am start -n com.example/.activities.MainActivity

Answer 3

I wrote this task to be able to install and also open the application on the device. Since I had multiple buildTypes and flavors with different application ids, it was not feasible to hard code the package name. So I wrote it like this instead:

android.applicationVariants.all { variant ->
    task "open${variant.name.capitalize()}" {
        dependsOn "install${variant.name.capitalize()}"

        doLast {
            exec {
                commandLine "adb shell monkey -p ${variant.applicationId} -c android.intent.category.LAUNCHER 1".split(" ")
            }
        }
    }
}

This would give you open{variant} for every install{variant} task you already have.
