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

1. Build project, install generated apk to device

# at the root dir of project
$ gradle installDebug

2. Open app on device

$ adb shell am start -n yourpackagename/.activityname

Answer 2

There are three commands to accomplish this:

1. ./gradlew assembleDebug #To build the project

2. adb install -r ./app/build/outputs/apk/app-debug.apk #To install it to the device

3. adb shell am start -n $PACKAGE/$PACKAGE.$ACTIVITY #To launch the application in the device, where $PACKAGE is the development package and $ACTIVITY is the activity to be launched (the launcher activity).

I've been writing a bash script to do this, with other few features.

Answer 3

$ gradle installDebug

This will push the debug build apk to device, but you have to manually start the application.

Answer 4

Build -> uninstall old verion -> install new version -> run application.

echo "Build application" && ./gradlew clean build && 
echo "Uninstall application" && adb uninstall [application package] && 
echo "Install application" && adb -d install app/build/outputs/apk/<build type>/[apk name].apk echo "Run application" && 
adb shell am start -n [application package]/.[application name]

Or if you want install and run application in debug type.

./gradlew installDebug && adb shell am start -n [application package]/.[application name]

Answer 5

Since you are using Gradle, you could simple add your own task in build.gradle

task appStart(type: Exec, dependsOn: 'installDebug') {
    // linux 
    commandLine 'adb', 'shell', 'am', 'start', '-n', 'com.example/.MyActivity'

    // windows
    // commandLine 'cmd', '/c', 'adb', 'shell', 'am', 'start', '-n', 'com.example/.MyActivity'      
}

then call it in your project root

$ gradle appStart

Update:

If you are using applicationIdSuffix ".debug", add .debug to the appId only but leave the activity untouched:

'com.example.debug/com.example.MyActivity'

Answer 6

task appStart(type: Exec, dependsOn: 'installDebug') {
    commandLine android.adbExe, 'shell', 'am', 'start', '-n', 'com.example/.MyActivity'
}
