Service doesn't run on continuous background location tracking

I want to track user location continuously even after they close the app. The service continuously stores location on DB and a wakefulintent starts a timertask to upload it to server. I have used
LocationServices.FusedLocationApi.requestLocationUpdates(Utils.googleApiClient,
mlocationrequest, this);
on a service. I have declared service on manifest as
<service
android:name="com.projest.services.BackgroundService"
android:enabled="true"
android:process=":Background">

and called servicew on my main activity using
Intent service = new Intent(this, BackgroundService.class);
startService(service);
but the service is not working. I couldn't see log.

What mistake am I making
I am working two weeks on this.Please help me.

you need to define android:stopWithTask="false" in manifest.
the process(Threads) run from the service will stop working if your app is removed from the recent apps. To ensure that your processes(Threads) remains always in running condition you have to Override onTaskRemoved() method and add code to restart Tasks like below.
#Override
public void onTaskRemoved(Intent rootIntent){
Intent restartServiceTask = new Intent(getApplicationContext(),this.getClass());
restartServiceTask.setPackage(getPackageName());
PendingIntent restartPendingIntent =PendingIntent.getService(getApplicationContext(), 1,restartServiceTask, PendingIntent.FLAG_ONE_SHOT);
AlarmManager myAlarmService = (AlarmManager) getApplicationContext().getSystemService(Context.ALARM_SERVICE);
myAlarmService.set(
AlarmManager.ELAPSED_REALTIME,
SystemClock.elapsedRealtime() + 1000,
restartPendingIntent);
super.onTaskRemoved(rootIntent);
}

Starting app when it shakes using broadcast

What I want is that when my app is in background and I shake the phone the app should start and come on foreground!
To achieve this I have used broadcast receiver as follows :
public class BootReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context arg0, Intent arg1) {
// TODO Auto-generated method stub
mSensorManager = (SensorManager) arg0.getSystemService(arg0.SENSOR_SERVICE);
mSensorManager.registerListener( mSensorIntentListener, mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER), SensorManager.SENSOR_DELAY_NORMAL);
}
}
I have registered it also as follows :
<receiver
android:name=".BootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
</intent-filter>
</receiver>
Now for shake event I am using this code as given below :
private final SensorEventListener mSensorIntentListener = new SensorEventListener() {
public void onSensorChanged(SensorEvent se) {
float x = se.values[0];
float y = se.values[1];
float z = se.values[2];
mAccelLast = mAccelCurrent;
mAccelCurrent = (float) Math.sqrt((double) (x*x + y*y + z*z));
float delta = mAccelCurrent - mAccelLast;
mAccel = mAccel * 0.9f + delta; // perform low-cut filter
if (mAccel > 12) {
Toast.makeText(getApplicationContext(), "Device has shaken.", Toast.LENGTH_LONG).show();
Intent intent = new Intent(getApplicationContext(), MainActivity.class)
.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}
}
#Override
public void onAccuracyChanged(Sensor arg0, int arg1) {
// TODO Auto-generated method stub
}
};
Now when I try to run the app and put it on background and shake it doesn't works !
So what is the logical error and how to make my app come foreground on shake ?
One more thing I am using nested classes concept so all classes are in MainActivity class !
code full !
:
package com.example.sensorlist;
public class MainActivity extends ActionBarActivity {

Your <receiver> element will not work. If you were to look at LogCat on a reboot, you would see warnings or errors from Android, saying that it cannot find your BootReceiver class. A manifest-registered receiver cannot be a nested class inside of an activity.
Get rid of the <receiver> element. Get rid of BootReceiver. Register your SensorEventListener in onCreate() of your activity. So long as your process is running (which may not be very long), and so long as the device is turned on, you should receive sensor events.

To capture shakes you should use always-on low power sensors, registered in a wakelocked sticky service. To reach a great amount of devices, your app should find what of that low power sensors are available in the phone. And then use the best combination, minimizing battery power drain. You will need also to ensure your app is whitelisted for battery optimization, so your app can survive in background.

How to call a condition on a view?

I have two activities in first activity, I have two text views fromLocation and toLocation. On click of from and to text view I am calling next activity in which I have a map and I choose a location which I am storing in string and showing on text view. This choose location I want to show on fromLocation text view of first activity onClick of a layout of useLocation in second activity on the basis of which text view is choose. If onClick of fromLocation the address should show on fromLocation text view and onClick of toLocation address should show on toLocation. This will be onResume method of first activity.
Now I am getting the address on both text views when I choose address for first time onClick on fromLocation text view.
How to do this..?

If i understand correctly.. You should launch second activity as startActivityForResult and after choosing location on map return it as a result.
The first activity should now this value from the method onActivityResult

Click on first textview launch second activity with requestcode
Second activity after choosing location finishes with setResult, where you store chosen location
Get the result in onActivityResult of first activity and set it to textView
the same for second textview. Use different requestcodes for different textview, which you should check in onActivityResult to determine which textView data was chosen in second activity

How can I send current location from one activity to another?

I am using map to get current location and now I want to send my current location to another activity which has form to input all the data.
I am confused about which variables and methods I should use to send the location data.
ChooseFromMapActivity
This is the activity where I am getting my current location. And now on Click of useLocation layout I want to send this location to the edit text of another activity i.e GoSendActivity.

public void setmToloc_details(){this.mToloc_details=mToloc_details;}
public void setmItems_details(){this.mItems_details=mItems_details;}
}
How can I achieve this?? Please help..

try this :
useLocation.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(ChooseFromMapActivity.this , GoSendActivity.class);
intent.putExtra("Latitude", latitude);
intent.putExtra("Longitude", longitude);
startActivity(intent);
}
});
And inside onCreate of GoSendActivity,get latitude and longitude like this :
Bundle extras = getIntent().getExtras();
if (extras != null) {
double latitude = extras.getDouble("Latitude");
double longitude = extras.getDouble("Longitude");
}
Now you can set latitude and longitude to your edittext edittext.setText(String.valueOf(latitude));

Apart from passing the data to the next activity using intents, you can also use shared preferences, TinyDB lib achieves great results for caching data. Yoou will need to sync this in your gradle file :
compile 'com.mukesh:tinydb:1.0.1'
then in your onCreate in each activity you will be using the same, initialize the tinyDB by passing application context
TinyDB tinyDB = new TinyDB(getApplicationContext());
With that you can store and retrieve any data within the app using a key-value pair,example to store your coordinates, just call :
tinyDB.putDouble("latitude",latitude);
tinyDB.putDouble("longitude",longitude);
And you can retrieve the data this way:
double latitude = tinyDB.getDouble("latitude");
double longitude = tinyDB.getDouble("longitude");
This class supports all data formats, from Strings,Double,Float and even objects such as ararayLists. Would highly recommend you to try it out.

Make this class as serialisable and put it into intent using bundle.putSerializable("myclaa",location).
Class Location implements Seraializable{
}

Service and Notification refreshed when Activity is closed

I have a Service with a Notification with a Progress Bar inside. This Service is started when i open the Main Activity and works fine. But, when i close Main Activity (onDestroy() is called) the Notification is like refreshed. This is the code of my Service.
#Override
public void onCreate() {
super.onCreate();
Mypreferences prefs = new Mypreferences(this);
String minutes = prefs.getStringValueOf("Minutes");
final NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
final NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
d = Integer.valueOf(minutes)*60;
builder.setSmallIcon(R.drawable.ic_action_about);
builder.setContentTitle(getString(R.string.app_name));
new Thread(new Runnable() {
#Override
public void run() {
// TODO Auto-generated method stub
for(int i=0;i<d;i++) {
builder.setProgress(d, d-i, false);
builder.setContentInfo(d-i+"/"+d);
notificationManager.notify(0, builder.build());
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}).start();
Integer d it's 60 and countdown works fine but when i close MainActivity if for example ProgressBar is at 40, return to 60. Why? How can i solve?
Service code
#Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
#Override
public void onCreate() {
super.onCreate();
pref = new SharedPref(this);
map = pref.getAllPrefs();
boolean delay = pref.loadBooleanPref("delay");
String delayTime = pref.loadStringValue("DelayTime");
if(delay && delayTime != null) {
new CountDownTimer(TimeUnit.MINUTES.toMillis(Long.valueOf(delayTime)), 1000) {
#Override
public void onTick(long millisUntilFinished) {
// TODO Auto-generated method stub
}
#Override
public void onFinish() {
// TODO Auto-generated method stub
getInfo();
}
}.start();
} else {
getInfo();
}
}
