I wanted to test android auto sample (Hello World notification) app given in developer guide samples.
I followed the steps - https://developer.android.com/training/auto/start/index.html
Tried launching messaging simulator and then, waiting for "Hello World" notification on auto simulator (messaging-simulator app). But nothing appeared. Should I look into messaging/inbox folder? tried restarting as well.
I have got it! Its a Messaging Sample App which will be launched in Android Fragment. Also, if the app doesn't launch yet, stop the simulator from Settings > Apps then restart it.
