My LogCat is displaying idsactly what I described. Would really appreciate a fix guys!
I've seen this for a number of months on my S3 and it's never appeared to cause any problems. The answer here sounds probable to me.

I am trying to retrieve step counts from a smartwatch and push it to API. I was able to retrieve and push the data when I open the app. But once it is not activated, then it will not send any data. I am trying to use the android service to run the app in the background so that it will send the data continuously. I have given all the permissions and enabled them.
This is MainActivity.java
package com.example.stepcounter;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity{
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
protected void onResume() {
super.onResume();
}
protected void onPause() {
super.onPause();
}
protected void onDestroy() {
super.onDestroy();
}
public void onPressStartService(View v){
Intent intent = new Intent(this, MyService.class);
startService(intent);
}
public void onPressStopService(View v){
stopService(new Intent(getApplicationContext(), MyService.class));
}
}
And this is MyService.java
package com.example.stepcounter;
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.os.IBinder;
import android.hardware.Sensor;

public class MyService extends Service implements SensorEventListener {

private String HelloData;
private TextView mTextView;
private boolean isSensorPresent;
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
mSensorManager = (SensorManager)this.getSystemService(Context.SENSOR_SERVICE);
if(mSensorManager.getDefaultSensor(Sensor.TYPE_HEART_RATE) != null) {
mSensor = mSensorManager.getDefaultSensor(69680);
isSensorPresent = true;
} else {
isSensorPresent = false;
}
mSensorManager.registerListener(this, mSensor, SensorManager.SENSOR_DELAY_NORMAL);
return START_STICKY;
}
#Nullable
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onSensorChanged(SensorEvent event) {
mTextView.setText("Heart Rate: " + String.valueOf(event.values[0]));
HelloData = (String) String.valueOf(event.values[0]);
if(!HelloData.contains("0.0")){
postDataUsingVolley(HelloData);
}
}
#Override
public void onAccuracyChanged(Sensor sensor, int i) {
}
private void postDataUsingVolley(String ranData) {
String url = "https://test.com";
RequestQueue queue = Volley.newRequestQueue(this);
JSONObject postData = new JSONObject();
try {
postData.put("data", ranData);
} catch (JSONException e) {
e.printStackTrace();
}
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, url, postData, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
System.out.println(response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
error.printStackTrace();
}
});
queue.add(jsonObjectRequest);
}
}
I have also added the following in AndroidManifest.xml
<service
android:name=".MyService"
android:enabled="true"
android:exported="true"></service>
It works for 30 seconds, send the data and once the watch goes inactive, it stops sending data. Any idea what is wrong with this?
You need to unregister your Sensor during onPause:
#Override
protected void onPause() {
super.onPause();
sensorManager.unregisterListener(this);
}
Also, if you unregister, you need to use your boolean activityRunning.
Any thoughts why doesnt this code invoke the onResults method ?

-in my AndroidManifest.xml I got the uses-permission I really dont know whats wrong any opinion is welcomed, It seems like the app is somehow skipping initializeSpeechRecognizer();. The app is only supposed to repeat what I said so thats why my processResult method contains only speak("command");
The problem was that my virtual device for some reason didn't cooperate with PC mic, on real machine it works.
Ya guys i have tried a lot of answers on this website and that all doesn't work at all

as mentioned in this answer i guess GooglePlayServiceClient and has become outdated so remove it and use GoogleApiClientinstead.Also LocationServices.API, and FusedLocationProviderApi were introduced.
Usage of GoogleApiClient :
To use GoogleApiClient the first thing to change is the interface, the activity or service is implementing
//old code of GooglePlayServiceClient :
public class LocationMonitoringService extends Service implements GooglePlayServicesClient.ConnectionCallbacks
//replace the above ^ code with this: new code for GoogleApiClient
public class LocationMonitoringService extends Service implements GoogleApiClient.ConnectionCallbacks
in GooglePlayServiceClient, mLocationClient was just a regular class constructor.
inGoogleApiClient a Builder is used like :
//old code of GooglePlayServiceClient :
LocationClient mLocationClient;
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
mLocationClient = new LocationClient(this, this, this);
mLocationClient.connect();
}
replace it^ with new builder code of GoogleApiClient :
GoogleApiClient mLocationClient;
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
mLocationClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
mLocationClient.connect();
}
Examples :
Requesting location :
Old code was just a simple call like
mLocationClient.requestLocationUpdates(mLocationRequest, locationListener);
in GoogleApiClient we use FusedLocatonApi like :
LocationServices.FusedLocationApi.requestLocationUpdates(mLocationClient, mLocationRequest, locationListener);
This post shows you a implementation of most of the methods like :onConnected onConnectionFailed onConnectionSuspended etc.
I am trying to get the friends list of the current logged-in user.

for (GraphUser u : users) {
friendsList.add(buildFriendInfoHolder(u));
}
Intent intent = new Intent(parentActivity,
FriendListActivity.class);
intent.putParcelableArrayListExtra("friends_list",
friendsList);
parentActivity.startActivity(intent);
} else {
Log.i("users_status", "null");
}
}

The problem is the users list (List<GraphUser> users) is always null.
I previously set the read permission as follows:
authButton.setReadPermissions(Arrays.asList("read_friendlists"));
So, I am not sure what's wrong. Here is the full Code:
Solved: I didn't add the INTERNET permission in my manifest file.
