Android Wearable Message API根本不起作用

Question

I tried some basic communication tutorial between mobile(handheld) and wearable but it doesn't work at all. Whenever I check the result of sendMessage, it says SUCCESS but receiver is never called.

I also changed deprecated com.google.android.gms.wearable.BIND_LISTENER to com.google.android.gms.wearable.DATA_CHANGED and com.google.android.gms.wearable.MESSAGE_RECEIVED but it still not working.

Does this log relevant to this phenomenon?

Answer 1

It was because the app never called GoogleApiClient's connect method such as googleApiClient.connect() and googleApiClient.blockingConnect() . However, while investigating the issue, I created some working skeleton app for Android Wearable Messaging API . *I also resolved the outdated warning by setting Play-Service-Wearable 's version into "7.5.0".
