Android service restarts, but application does not - android

I am developing an application that sends over a webservice information about the last dialed number, call status, and duration of the call.
The application works perfectly fine, but when the device closes the application the android service does restart but the activity does not.
The way I am sure about that is that I have Toasts when the service is started: "Servicio TRUCKA iniciado" and "Servicio TRUCKA creado" tell me that the service has been created and started.
And when the information is sent to the webservice I have toasts saying: "Enviando información..." and "Información enviada."
But when the application is closed (via the android task manager that automatically closes apps) the messages from the service "Servicio TRUCKA iniciado" and "Servicio TRUCKA creado" do appear, but the toasts from the information sent part do not.
I hope someone can help me and tell what am I doing wrong? :)

android - app keeps crashing on searching

so I've created an app which sets an alarm 25 mins before your departure time, based on the estimated time taken to travel from your place of departure to your destination.
I am able to build the app, but the app keeps crashing whenever I press the search button. I am guessing it has something to do with the integration of the placeautocomplete fragment, but not sure what about it.

If file does not exist, create it and write string to it. If it does then append string to it. Isn't working right

Okay, I read a lot and thought I had this worked out but apparently not. What I'm trying to do is check to see if a file exists (in this case heapFile.csv) and if it doesn't to create it and then write a string to it. If the file does exist, then I want to append the string to the file. I get no errors when I run this though I do get a warning saying that it can't create the file although it actually does do so. However it's not writing the string to the file in either case. I'm probably just not using the right syntax or something but after staring at this for weeks I can't see the forest for the trees and find the problem. Aside from this one issue my program is working fine and if I can just get this working I can FINALLY finish this. Any help is incredibly appreciated.
Here's the java file. I think it's clear where the file creation/writing bit is.

Edited my question to include the manifest so you can see the permissions I've got. I think it's right but I'm not certain...
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

use this:
String file = heapFile.getAbsolutePath();
FileWriter heapFileWritter = new FileWriter(file, true);
getName() would give you just the name of the file. But you need to provide absolutepath for FileWriter.

Write or append string to a file. Getting read only file system error

First off I wanted to thank everyone for the help I've gotten on my last few questions. I've searched and done my best to figure out my latest problem but I've had no luck even after searching here. I'm trying to check to see if "heapFile.csv" exists and if it doesn't, to create the file and then write a string to it. If it does then I just want to append a string to it instead. I think what I have will do that but I keep getting an IOException along with it saying the file system is Read Only. I do have the manifest file changed to include accessing the sdcard and even used the android too to make a virtual sdcard in case that was the problem.

I think problem is in this line:
FileWriter heapFileWritter = new FileWriter(
heapFile.getName(), true);
instead try this:
FileWriter heapFileWritter = new FileWriter(
heapFile, true);
explanation:
heapFile.getName() refers to your file name so lets say heapFile.txt.
so when you ask FileWriter to write to this file. It doesn't know which file you are referring to. So it try to create the file. But wait! where it will create the file, as it has only the file name, not the complete path.
So even I am sure where it would think of creating the file, my guess is Root( I am not sure). Which is read-only hence the error.
public FileWriter(String fileName,
boolean append)
throws IOException
IOException - if the named file exists but is a directory rather than
a regular file, does not exist but cannot be created, or cannot be
opened for any other reason
