java - Request - Response API for Android Wear 2.0? -


how implement request-response protocol android wear 2.0 app?

scenario:

when tap on button on watch, want fetch data phone , display on watch's screen.

what tried:

i implemented working example using messageapi, don't it. send dummy "request" in 1 place using 1 method, disregard pendingresult , hope receive message corresponding response.

ideally, i'd have is:

byte[] responsebytes = sendrequest(somerequestbytes);

i'm not sure have tried.

but code should work send byte array.

wearable.messageapi.sendmessage(googleapiclient, transcriptionnodeid,             voice_transcription_message_path, voicedata).setresultcallback(                   new resultcallback() {                       @override                       public void onresult(sendmessageresult sendmessageresult) {                           if (!sendmessageresult.getstatus().issuccess()) {                               // failed send message                           }                       }                   }             );

voicedata simple byte array. array received both wearable , handheld device.

to retrieve data use this:

@override public void onmessagereceived(messageevent messageevent) {     if (messageevent.getpath().equals(your_text)) {         messageevent.getdata();//this byte array     } }

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
