Android Wear device not detecting any Nodes (phones) DataApi - java

I have and android wear and android phone app. I'm trying to get them connect and ultimately send messages from the watch to the phone. On the watch though, Wearable.CapabilityApi.getCapability() returns no nodes
Here is the Wear MainActivity:
public class MainActivity extends WearableActivity {
public static final String TAG = "WatchApp";
public GoogleApiClient mApiClient;
public static final int CONNECTION_TIME_OUT_MS = 1000;
public static String nodeId;
private static final String AIR_LIFT_CAPABILITY = "airlift";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initApi();
final Button btnUp = (Button)findViewById(R.id.btnUp);
btnUp.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String text = "Preset";
//mAdapter.add( text );
//mAdapter.notifyDataSetChanged();
sendMessage( text );
Log.i("WatchApp", "btnUp Sent Preset");
}
});
Button btnDown = (Button)findViewById(R.id.btnDown);
btnDown.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String text = "AirOut";
//mAdapter.add( text );
//mAdapter.notifyDataSetChanged();
sendMessage(text );
Log.i("WatchApp", "btnUp Sent AirOut");
}
});
// Enables Always-on
setAmbientEnabled();
}
private void initApi() {
mApiClient = getGoogleApiClient(this);
setOrUpdateNotification();
Log.i("WatchApp", "initApi()");
}
private GoogleApiClient getGoogleApiClient(Context context) {
return new GoogleApiClient.Builder(context)
.addApi(Wearable.API)
.build();
}
private void setOrUpdateNotification() {

updateFindMeCapability(result.getCapability());
CapabilityApi.CapabilityListener capabilityListener =
new CapabilityApi.CapabilityListener() {
#Override
public void onCapabilityChanged(CapabilityInfo capabilityInfo) {
updateFindMeCapability(capabilityInfo);
}
};
// Wearable.CapabilityApi.addCapabilityListener(mApiClient, capabilityListener, AIR_LIFT_CAPABILITY);
}
}).start();
}
private void updateFindMeCapability(CapabilityInfo capabilityInfo) {
if (capabilityInfo.getNodes() == null) return;
Set<Node> connectedNodes = capabilityInfo.getNodes();
if (connectedNodes.isEmpty()) {
Log.i(TAG,"No Nodes Found.");
} else {

}
}
}
}
private void sendMessage(final String MESSAGE) {

mApiClient.disconnect();
Log.i("WatchApp", "Message ("+MESSAGE+") sent");
}
}).start();
} else {

}
}
#Override

Any ideas why I get null result for returned nodes? my phone and watch are currently paired and i get updates on my watch from my phone from things like facebook and emails.


As stated in this thread, NodeApi can be used on the device side.
NodeApi.GetConnectedNodesResult nodes =
Wearable.NodeApi.getConnectedNodes(mApiClient).await();
Then for each node within nodes, you can call getDisplayName().
Also, based from this link, use the same debug certificate for both the handheld and wearable app, otherwise the CapabilityAPI won't work.

Service doesn't work with Oreo 8.1 - The Detector does not work, nor does the process in the background

My call detector app is running fine on all android version except 8 Oreo. I get a deadlock paradigm: My detector is not called, and when I close the application the system kills it, not leaving it in the background.
I have already read the documentation from cable to tail https://developer.android.com/about/versions/oreo/background, I already looked a lot in google, and here in stack over flow, but no solution applied to my case, because of the required "dangerous" permissions.
My case seems simple: I have a detector, a service and the main with a button. I want it when the user calls a certain number, my main open.
What is the right way to fix this issue?

Replace reciever in your Manifest by receiver.
Moreover, make sure your app successfully got the token (registration device Id). Hope this helps!
My Manifest:

Moreover, check your sever-side response after sending. Perhaps you will get response message like the following if GCM message sucessfully sent:
{"multicast_id":6371085842931382567,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1240780242421810%4c427ca6f9fd7ecd"}]}
About getting token, firstly, I check SharedPreferences, if empty, get token (device registration id) from Google server. Token will be stored in SharedPreferences for other use / providing to server-side app.
public class MainActivity extends Activity {
Context mContext = this;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
...
SharedPreferences appPrefs = mContext.getSharedPreferences("com.example.gcmclient_preferences", Context.MODE_PRIVATE);
String token = appPrefs.getString("token", "");
if (token.isEmpty()) {
try {
getGCMToken("0123456789"); // Project ID: xxxx Project Number: 0123456789 at https://console.developers.google.com/project/...
} catch (Exception ex) {
ex.printStackTrace();
}
}
...
}
...
private void getGCMToken(final String senderId) throws Exception {
new AsyncTask<Void, Void, Void>() {
#Override
protected String doInBackground(Void... params) {
String token = "";
try {
InstanceID instanceID = InstanceID.getInstance(mContext);
token = instanceID.getToken(senderId, GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);
if (token != null && !token.isEmpty()) {
SharedPreferences appPrefs = mContext.getSharedPreferences("com.example.gcmclient_preferences", Context.MODE_PRIVATE);
SharedPreferences.Editor prefsEditor = appPrefs.edit();
prefsEditor.putString("token", token);
prefsEditor.commit();
}
Log.i("GCM_Token", token);
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
}.execute();
}
}

Change this line
android:name=".MyGcmListenerService"
instead of above line
android:name="your package.MyGcmListenerService"
example com.yourappname.gcm.GcmIntentService
<service
android:name=".MyGcmListenerService"
android:exported="false" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
</intent-filter>
</service>
simple example code for BroadCastReceiver.
public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
// Explicitly specify that GcmIntentService will handle the intent.
ComponentName comp = new ComponentName(context.getPackageName(),
GcmIntentService.class.getName());
// Start the service, keeping the device awake while it is launching.
startWakefulService(context, (intent.setComponent(comp)));
setResultCode(Activity.RESULT_OK);
}
}

// in your BroadcastReceiver.
String messageType = gcm.getMessageType(intent);
if (!extras.isEmpty()) { // has effect of unparcelling Bundles
/*
* Filter messages based on message type. Since it is likely that GCM
* will be extended in the future with new message types, just ignore
* any message types you're not interested in, or that you don't
* recognize.
*/
if (GoogleCloudMessaging.
MESSAGE_TYPE_SEND_ERROR.equals(messageType)) {
sendNotification("Send error: " + extras.toString());
} else if (GoogleCloudMessaging.
MESSAGE_TYPE_DELETED.equals(messageType)) {
sendNotification("Deleted messages on server: " +
extras.toString());
// If it's a regular GCM message, do some work.
} else if (GoogleCloudMessaging.

Log.e(":::gcm message",extras.getString("key");
}
}
// Release the wake lock provided by the WakefulBroadcastReceiver.
GcmBroadcastReceiver.completeWakefulIntent(intent);

Issue By Lastlocation

I write a program that determine my Location. I follow only the instructions from Google pages this and this.
When the program runs on my Galaxy note 4 (android 5.0.1), it gives me a popup to choose my account then I choose that but after that comes other empty popup and stays there, without to give me my location.
But when I click outside the popup, the popup goes and I see the map normally without my location.
I have only one class, this:
public class MainActivity extends FragmentActivity implements ConnectionCallbacks, OnConnectionFailedListener {
private GoogleApiClient mGoogleApiClient;
private static final int REQUEST_RESOLVE_ERROR = 1001;
private static final String DIALOG_ERROR = "dialog_error";
private boolean mResolvingError= false;
private static final String STATE_RESOLVING_ERROR = "resolving_error";

mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(Drive.API)
.addScope(Drive.SCOPE_FILE)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
mResolvingError = savedInstanceState != null && savedInstanceState.getBoolean(STATE_RESOLVING_ERROR,false);
}
#Override

super.onStart();
if(!mResolvingError)
mGoogleApiClient.connect();
};
#Override

super.onStop();
};

return;
else if(result.hasResolution()){
try {
mResolvingError = true;
result.startResolutionForResult(this, REQUEST_RESOLVE_ERROR);
} catch (SendIntentException e) {
mGoogleApiClient.connect();
}
}
else{
showErrorDialog(result.getErrorCode());
mResolvingError = true;
}
}
#Override
public void onConnected(Bundle connectionHint) {
Location mLastLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
if(mLastLocation != null){
//mLatitudeText.setText(String.valueOf(mLastLocation.getLatitude()));
//mLongitudeText.setText(String.valueOf(mLastLocation.getLongitude()));
}
}
#Override
public void onConnectionSuspended(int arg0) {

}
private void showErrorDialog(int errorCode) {
ErrorDialogFragment dialogFragment = new ErrorDialogFragment();
Bundle args = new Bundle();
args.putInt(DIALOG_ERROR,errorCode);
dialogFragment.setArguments(args);
dialogFragment.show(getSupportFragmentManager(),"errordialog");
}
public void onDialogDismissed(){
mResolvingError =false;
}
/* A fragment to display an error dialog */
public static class ErrorDialogFragment extends DialogFragment{
public ErrorDialogFragment(){};
public Dialog onCreatDialog(Bundle savedInstanceState){
int errorCode = this.getArguments().getInt(DIALOG_ERROR);
return GooglePlayServicesUtil.getErrorDialog(errorCode, this.getActivity(), REQUEST_RESOLVE_ERROR);
}
#Override
public void onDismiss(DialogInterface dialog){
((MainActivity)getActivity()).onDialogDismissed();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_RESOLVE_ERROR) {
mResolvingError = false;
if (resultCode == RESULT_OK) {
// Make sure the app is not already connected or attempting to connect
if (!mGoogleApiClient.isConnecting() &&
!mGoogleApiClient.isConnected()) {
mGoogleApiClient.connect();
}
}
}
}
#Override
protected void onSaveInstanceState(Bundle outState){
super.onSaveInstanceState(outState);
outState.putBoolean(STATE_RESOLVING_ERROR, mResolvingError);
}
}
and my manifest is:
<?xml version="1.0" encoding="utf-8"?>

I think this section is wrong
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(Drive.API)
.addScope(Drive.SCOPE_FILE)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
and must be changed into
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(LocationServices.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
The problem is where you specifies the API Type.
