Ich versuche dem Nest SDK auf Github und dem Beispielcode zu folgen. Mein Fragment-Code ist wie folgt -Das Nest Thermostat funktioniert mit der Android-App
/**
* A placeholder fragment containing a simple view.
*/
public class ThermoActivityFragment extends Fragment implements View.OnClickListener {
private static final String TAG = ThermoActivity.class.getSimpleName(); // for log
// Nest API instance holder
private NestAPI tNest;
private NestToken tToken;
private Thermostat tThermo;
private Structure tStruct;
// Save the ID's and secret
private static final String CLIENT_ID = Constants.CLIENT_ID;
private static final String CLIENT_SECRET = Constants.CLIENT_SECRET;
private static final String REDIRECT_URL = Constants.REDIRECT_URL;
private static final int AUTH_TOKEN_REQUEST_CODE = 111;
private static final int RESULT_OK = -1;
private static final String THERMOSTAT_KEY = "thermostat_key";
private static final String STRUCTURE_KEY = "structure_key";
private static final String DEG_F = "%d°F";
// Text View
private TextView tTempIncr;
private TextView tTempDecr;
private TextView tSetTemp;
public ThermoActivityFragment() {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_thermo, container, false);
tTempIncr = (TextView) view.findViewById(R.id.temp_incr);
tTempDecr = (TextView) view.findViewById(R.id.temp_decr);
tSetTemp = (TextView) view.findViewById(R.id.temp_value);
view.findViewById(R.id.temp_incr).setOnClickListener(this);
view.findViewById(R.id.temp_decr).setOnClickListener(this);
NestAPI.setAndroidContext(getContext());
tNest = NestAPI.getInstance();
tNest.setConfig(CLIENT_ID, CLIENT_SECRET, REDIRECT_URL);
// Auth flow
tToken = ThermoSettings.loadAuthToken(getContext());
if (tToken != null) {
authenticate(tToken);
} else {
tNest.launchAuthFlow(getActivity(), AUTH_TOKEN_REQUEST_CODE);
}
if (savedInstanceState != null) {
tThermo = savedInstanceState.getParcelable(THERMOSTAT_KEY);
tStruct = savedInstanceState.getParcelable(STRUCTURE_KEY);
//updateViews();
}
return view;
}
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putParcelable(THERMOSTAT_KEY, tThermo);
outState.putParcelable(STRUCTURE_KEY, tStruct);
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (resultCode != RESULT_OK || requestCode != AUTH_TOKEN_REQUEST_CODE) {
Log.e(TAG, "Finished with no result.");
return;
}
tToken = NestAPI.getAccessTokenFromIntent(intent);
if (tToken != null) {
ThermoSettings.saveAuthToken(getContext(), tToken);
authenticate(tToken);
} else {
Log.e(TAG, "Unable to resolve access token from payload.");
}
}
@Override
public void onStop() {
Log.d(TAG, "onStop");
super.onStop();
tNest.removeAllListeners();
}
@Override
public void onClick(View v) {
if (tThermo == null || tStruct == null)
return;
String tThermoId = tThermo.getDeviceId();
long temp = tThermo.getTargetTemperatureF();
switch (v.getId()) {
case R.id.temp_incr:
System.out.println("Temp Incr");
++temp;
tSetTemp.setText(String.format(DEG_F, temp));
tNest.thermostats.setTargetTemperatureF(tThermoId, temp);
break;
case R.id.temp_decr:
--temp;
tSetTemp.setText(String.format(DEG_F, temp));
tNest.thermostats.setTargetTemperatureF(tThermoId, temp);
break;
}
}
/**
* Authenticate with the Nest API and start listening for updates.
*
* @param token the token used to authenticate.
*/
private void authenticate(NestToken token) {
//NestAPI nest = NestAPI.getInstance();
tNest.authWithToken(token, new NestListener.AuthListener() {
@Override
public void onAuthSuccess() {
Log.v(TAG, "Authentication succeeded.");
fetchData();
}
@Override
public void onAuthFailure(NestException exception) {
Log.e(TAG, "Authentication failed with error: " + exception.getMessage());
ThermoSettings.saveAuthToken(getActivity(), null);
tNest.launchAuthFlow(getActivity(), AUTH_TOKEN_REQUEST_CODE);
}
@Override
public void onAuthRevoked() {
Log.e(TAG, "Auth token was revoked!");
ThermoSettings.saveAuthToken(getActivity(), null);
tNest.launchAuthFlow(getActivity(), AUTH_TOKEN_REQUEST_CODE);
}
});
}
/**
* Setup global listener, start listening, and update view when update received.
*/
private void fetchData() {
tNest.addGlobalListener(new NestListener.GlobalListener() {
@Override
public void onUpdate(@NonNull GlobalUpdate update) {
tThermo = update.getThermostats().get(0);
//System.out.println(tThermo);
tStruct = update.getStructures().get(0);
//updateViews();
}
});
}
}
Die Einstellungsdatei, wo ich das Token speichern ist wie folgt -
public class ThermoSettings {
private static final String TOKEN_KEY = "token";
private static final String EXPIRATION_KEY = "expiration";
public static void saveAuthToken(Context context, NestToken token) {
if (token == null) {
getPrefs(context).edit().remove(TOKEN_KEY).remove(EXPIRATION_KEY).commit();
return;
}
getPrefs(context).edit()
.putString(TOKEN_KEY, token.getToken())
.putLong(EXPIRATION_KEY, token.getExpiresIn())
.commit();
}
public static NestToken loadAuthToken(Context context) {
final SharedPreferences prefs = getPrefs(context);
final String token = prefs.getString(TOKEN_KEY, null);
final long expirationDate = prefs.getLong(EXPIRATION_KEY, -1);
if (token == null || expirationDate == -1) {
return null;
}
return new NestToken(token, expirationDate);
}
private static SharedPreferences getPrefs(Context context) {
return context.getSharedPreferences(NestToken.class.getSimpleName(), 0);
}
}
Was ich versuche zu tun - Ich bin mit einem Knopf auf der Homepage, um die Aktivität einzugeben. Wenn ich auf die Schaltfläche klicke, wird die Website zur Autorisierung von Nest angezeigt. Wenn ich auf "Akzeptieren" klicke, wird zwar meine Benutzeroberfläche angezeigt, aber die Meldung "Authentifizierung erfolgreich" wird nicht im Protokoll angezeigt. Kann mir jemand sagen, was ich falsch mache?
