Я хочу отправить только простые строки из Smartphone в android износ. Я просмотрел этот вопрос раньше: Unable to push data to android wear (Emulator) и попытался сделать то же самое, но onDataChanged только тогда, когда я удаляю приложение App на своем телефоне, но не тогда, когда вызывается push StringstoWear. Надежды на помощь ...onDataChanged isn't вызван на android износ
Вот мой код на телефоне: package de.gruppe8.culturehelper;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.wearable.PutDataMapRequest;
import com.google.android.gms.wearable.Wearable;
import java.util.Date;
public class Phone extends AppCompatActivity implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {
private GoogleApiClient mGoogleApiClient;
private static final String TAG = "PHONE";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_phone);
//Erstelle Google API Client zur Kommunikation mit Wear
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(Wearable.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
//Testbutton zum Daten versenden
Button button = (Button) findViewById(R.id.Testbutton);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
pushStringsToWear();
}
});
}
//Sendet Daten an Wear, wenn aufgerufen !!!!--->Auchtung wird noch nicht richtig empfangen
private void pushStringsToWear() {
Inhalt.TEXT ="ätzend";
//Requester
PutDataMapRequest Sender = PutDataMapRequest.create(Inhalt.NOTIFICATION_PATH);
//Diese Daten werden versendet, unter dem angegeben Pfad (siehe hier drüber)
Sender.getDataMap().putLong("time", System.currentTimeMillis());
Sender.getDataMap().putString("Bilddateiname", Inhalt.IMAGE);
Sender.getDataMap().putString("Text", Inhalt.TEXT);
Wearable.DataApi.putDataItem(mGoogleApiClient, Sender.asPutDataRequest());
//bestätigt das aufrufen der Funktion
TextView Information = (TextView) findViewById(R.id.Information);
String a= "dgdfjkjhg";
Information.setText(a);
}
//zu versendende Daten--->müssen anhand der Datenbank vor dem Absenden verändert werden
public static class Inhalt {
public static String NOTIFICATION_PATH = "/Warning";
public static Long Zeit = System.currentTimeMillis();
public static String IMAGE = "Image";
public static String TEXT = "content";
}
//Pflichtfunktionen onStart,onStop,onConnected,onConnectionFailed/Suspended, onStop
@Override
protected void onStart() {
super.onStart();
mGoogleApiClient.connect();
Log.d(TAG, "connected to APICLIENT" + new Date().getTime());
}
@Override
public void onConnected(Bundle bundle) {
Log.d(TAG, "Connected");
}
@Override
public void onConnectionSuspended(int i) {
Log.d(TAG, "Connection Suspended");
}
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
Log.d(TAG, "Connection Failed");
}
@Override
protected void onStop() {
super.onStop();
mGoogleApiClient.disconnect();
Log.d(TAG, "disconected from APICLIENT" + new Date().getTime());
}
}
И это мой код на Wear:
package de.gruppe8.culturehelper;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.widget.TextView;
import com.google.android.gms.common.ConnectionResult;

import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.wearable.DataApi;
import com.google.android.gms.wearable.DataEvent;
import com.google.android.gms.wearable.DataEventBuffer;
import com.google.android.gms.wearable.DataMapItem;
import com.google.android.gms.wearable.MessageApi;
import com.google.android.gms.wearable.MessageEvent;
import com.google.android.gms.wearable.Wearable;
import java.util.Objects;
public class Watch extends Activity implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, DataApi.DataListener, MessageApi.MessageListener {
private GoogleApiClient mGoogleApiClient;
private static final String TAG = "WEAR";
private TextView mTextView;
GoogleApiAvailability a;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_watch);
//Starten des Google API Clients zur kommunikation mit Smartphone
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(Wearable.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
}
//Wenn Daten vom Handy abgesendet werden, werden sie hier empfangen ---> Derzeit nur bei Deinstallation der App
public void onDataChanged(DataEventBuffer dataEvent) {
for (DataEvent event : dataEvent) {
if (event.getType() == DataEvent.TYPE_CHANGED &&
event.getDataItem().getUri().getPath().equals("/Warning")) {
final DataMapItem dMI = DataMapItem.fromDataItem(event.getDataItem());
//Empfangbare Daten, zur weiterverarbeitung If states einbauen und Folge festlegen(externe Funktionen?)
String Text = dMI.getDataMap().getString("Text");
String Bild = dMI.getDataMap().getString("Bilddateiname");
Long Zeit = dMI.getDataMap().getLong("time");
//Teststring
TextView Testergebnis = (TextView) findViewById(R.id.text);
String s= Objects.toString(Zeit, null);
Testergebnis.setText(s);
}
}
}
@Override
protected void onStart() {
super.onStart();
mGoogleApiClient.connect();
}
//Startet die Listener
@Override
public void onConnected(Bundle bundle) {
Wearable.DataApi.addListener(mGoogleApiClient, this);
Wearable.MessageApi.addListener(mGoogleApiClient, this);
}
@Override
protected void onStop() {
if (null != mGoogleApiClient && mGoogleApiClient.isConnected()) {
Wearable.DataApi.removeListener(mGoogleApiClient, this);
mGoogleApiClient.disconnect();
}
super.onStop();
}
@Override
public void onConnectionSuspended(int i) {
Log.d(TAG, "Connection Suspended");
}
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
Log.d(TAG, "Connection Failed");
}
@Override
public void onMessageReceived(MessageEvent messageEvent) {
}
}
