If you want an environment for basic compatibility
|
|
testing of your app, you can use your current APK and a
|
|
supported watch or an emulator. You don't necessarily need to update your
|
|
full development environment to do basic testing. To simply test your
|
|
app's compatibility with a preview system image, see <a href=
|
|
"{@docRoot}wear/preview/downloads.html">Download and Test with a
|
|
Device</a>.
|
|
</p>
|
|
|
|
<p>
|
|
However, to develop apps for the Android Wear 2.0 Developer Preview, you
|
|
need to make some updates to your development environment, as described
|
|
below.
