## Build and install

On Android Studio, click on the "Run" button.

If you prefer to run on the command line, type

```bash

./gradlew installDebug

adb shell am start com.example.androidthings.button/.ButtonActivity

```

If you have everything set up correctly, the LED will light up when you press

the button and light off when you release it.

## Enable auto-launch behavior

This sample app is currently configured to launch only when deployed from your

development machine. To enable the main activity to launch automatically on boot,

add the following `intent-filter` to the app's manifest file:

```xml

    

        

        

        

    

```
