Client not ready yet.. in Android wear watchface app

I am trying to build an app with watchface wear. my app runnning well but when I create watchface wear and set NoActivity and run wear app then it shows "Client not ready yet.." message in Run-Logcat like that-

$ adb push F:\Advanced_Android_Development\watchface\build\outputs\apk\watchface-debug.apk /data/local/tmp/com.example.android.sunshine.app
$ adb shell pm install -r "/data/local/tmp/com.example.android.sunshine.app"
Success
"Client not ready yet.."

And also when I opened Error-Logcat then it shows -

I'm seeing the client not ready message even after a successful install. Long press the watch face OR slide right to left then click bullet point list (to open a list of available watch faces) and check if it was installed. I'd look for the dog watch face because it stands out a lot.
