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;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.hardware.SensorManager;
import android.widget.TextView;
import androidx.annotation.Nullable;

import com.android.volley.RequestQueue;
import com.android.volley.Response;
import com.android.volley.VolleyError;
import com.android.volley.toolbox.JsonObjectRequest;
import com.android.volley.toolbox.Volley;
import org.json.JSONException;
import org.json.JSONObject;
public class MyService extends Service implements SensorEventListener {
private SensorManager mSensorManager;
private Sensor mSensor;
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.

I have an activity named Player Activity in which I am streaming music with the help of MediaPlayer API. Whenever my activity is created a notification is displayed which has some basic control of the music player.
So when I tap on my notification it jumps back to the Player Activity, but the state of the activity is lost.
Before tapping on notification :
After tapping on notification :
Here is the code of my notification's Pending Intent
Intent notifyIntent = new Intent(context, PlayerActivity.class);
notifyIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
notifyIntent.setAction("android.intent.action.MAIN");
notifyIntent.addCategory("android.intent.category.LAUNCHER");
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, notifyIntent, PendingIntent.FLAG_UPDATE_CURRENT);

Thanks in advance. Pardon me if the explanation is not clear, because if i might have right words to explain it, I would have googled it.
Add this to your PlayerActivity activity in manifest :
android:launchMode="singleTask"
And use these flags in the intent for pendingintent :
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
I have problem, dont know what to do, Goal is to make QR scanner, you enter value then press OK it should store the values in object podaci and to use same values in other activitiy.
But what happens it scans QR code but it doesnt show real value it shows something like this : "com.google.android.gms.vision.barcode.Barcode#ecd6456" and there is no value stored in object podaci in MainActivity.
here is my QR class :

I'm new to Android App Development and creating a simple service app. It has a button to start service and a button to stop service with their repective methods. Following is my code:
App3_main.java
package eg.app3;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
public class App3_main extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_app3_main);
}
public void startservice(View view)
{
Intent intent = new Intent(this,MyService.class);
startservice(intent); //this is where I'm getting the error mentioned in the title
}
public void stopservice(View view)
{
Intent intent = new Intent(this,MyService.class);
stopservice(intent); //this is where I'm getting the error mentioned in the title
}
}
MyService.java
package eg.app3;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.widget.Toast;
public class MyService extends Service {
public MyService() {
}
#Override
public void onCreate() {
super.onCreate();
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
Toast.makeText(this,"Service Started",Toast.LENGTH_LONG).show();
return START_STICKY;
}
#Override
public void onDestroy() {
Toast.makeText(this,"Service Stopped",Toast.LENGTH_LONG).show();
}
#Override
public IBinder onBind(Intent intent) {
return null;
}
}
Please guide me where I'm wrong.
Replace:
startservice(intent);
with:
startService(intent);
Then, replace:
stopservice(intent);
with:
stopService(intent);
Like most programming languages, Java is case-sensitive.

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 have an android service that plays music.i start in my main activity with this code:
Intent service = new Intent(MainMenu.this, musicservice.class);
MainMenu.this.startService(service);
and this is my service:
public class musicservice extends Service {
#Override
public IBinder onBind(Intent arg0) {
return null;
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
super.onStartCommand(intent, flags, startId);
MediaPlayer mp;
mp = MediaPlayer.create(musicservice.this, R.raw.music);
mp.setOnCompletionListener(new OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
mp.release();
}
});
mp.start();
return Service.START_STICKY;
}
#Override
public void onDestroy() {
super.onDestroy();
}
}
it stsrts work fine, but when i start another activity, my music goes off and seems my service destroys!! but dont want this, i want my service only stops when my application ends. music plays only when user works with app. even when app in in the background i want my music dont play! how i can implement this?
If you want your application to play music while your activity is on, try bind it.
it should look something like this:
Service:
package com.example.service;
import android.app.Service;
import android.content.Intent;
import android.media.MediaPlayer;
import android.media.MediaPlayer.OnCompletionListener;
import android.os.Binder;
import android.os.IBinder;
import com.example.playmusic.R;
public class PlayMusicService extends Service {
private final IBinder binder = new LocalBinder();
private MediaPlayer player;
#Override
public IBinder onBind(Intent intent) {
return binder;
}
public class LocalBinder extends Binder {
public PlayMusicService getService() {
return PlayMusicService.this;
}
}
public void play() {
player = MediaPlayer.create(this, R.raw.music);
player.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mp.release();
}
});
player.start();
}
public void pause() {
player.pause();
}
}
Activity:
package com.example.playmusic;
import android.app.Activity;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.content.ServiceConnection;
import android.os.Bundle;
import android.os.IBinder;
import com.example.service.PlayMusicService;
import com.example.service.PlayMusicService.LocalBinder;
public class MainActivity extends Activity {
private PlayMusicService service;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
protected void onPause() {
super.onPause();
service.pause();
}
#Override
protected void onStart() {
super.onStart();
if (service != null) {
service.play();
} else {
bindService();
}
}
private void bindService() {
bindService(new Intent(this, PlayMusicService.class), new ServiceConnection() {
#Override
public void onServiceDisconnected(ComponentName name) {
service = null;
}
#Override
public void onServiceConnected(ComponentName name, IBinder binder) {
LocalBinder localBinder = (LocalBinder) binder;
service = localBinder.getService();
service.play();
}
}, Context.BIND_AUTO_CREATE);
}
}
Service destroy when your activity destroy when you start service from activity.
Use AlarmManager to schedule the service repeatedly.
