How to packaging watch face app with auto install.

I released a customizable Watch face app for Android.
Band O'Clock for Wear : Google Play


There are some tricks for enable auto-install from phone.

■ AndroidManifest.xml

This is a AndroidManifest.xml for Wear app.
If you set com.google.android.permission.PROVIDE_BACKGROUND permission, auto-install seems not happen, but you can still select this app for watch face.

■ build.gradle

For build.gradle I changed

compile 'com.google.android.gms:play-services-wearable:+'

to

compile 'com.google.android.gms:play-services:5.0.+@aar'

for both mobile and wear project.

I'm not sure it really affect to auto-install, I did not confirm yet.
