回答1:
Instant Run is enabled by default for projects built using Android Gradle Plugin 2.0.0, or later. To update an existing project with the latest version of the Gradle plugin, go to the Settings dialog:
On Mac, click Android Studio → Preferences
On Windows and Linux, click File → Settings
In the Settings/Preferences dialog, go to Build, Execution, Deployment → Instant Run.
Click the Update Project link. When prompted, click OK.
If the the Update Project link does not appear, your project is already up to date.
Using Instant Run
To first run your app, click Run ‘app’ (or Debug ‘app’ ). Android Studio will run your app by compiling, dexing, packaging and installing an .APK file, and launching the app. After your app has launched, a small, yellow thunderbolt will appear with the Run ‘app’ button (or Debug ‘app’ button). This indicates that the Instant Run feature is ready.
Clicking Run ‘app’ (or Debug ‘app’) again will start an Instant Run and your changes are pushed to the connected device within a few seconds.
To terminate the running app on your device, click Stop ‘app’ .

Instant Run is enabled by default on newly created projects and it can be turned on for existing apps in the project settings at Build, Execution, Deployment -> Instant Run. Build scripts will have to be updated to use v2.0.0-alpha of the Gradle plugin. As always, this is still very new and may not be completely stable.
