I am trying to create an Android app in Android Studio.
The app is mainly a background service to send some information to the server around every 15 seconds or so.
I have created an empty activity, boot receiver and a service class, but it doesn't work.
Could somebody help me, and explain why it doesn't work.
The relevant files:
MainActivity.java
package nl.robinvandervliet.robinsapp.app;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;

{
super.onCreate(savedInstanceState);
finish();
}
}

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class BootReceiver extends BroadcastReceiver
{
#Override
public void onReceive(Context context, Intent intent)
{
context.startService(new Intent(context, RobinsService.class));
}
}
RobinsService.java
package nl.robinvandervliet.robinsapp.app;
import android.app.Notification;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.widget.Toast;
public class RobinsService extends Service
{
private Runnable runnable = new Runnable()
{
#Override
public void run()
{
//Opening connection to the server.
while (true)
{
//Sending some data to the server.
//Sleeping for around 15 seconds.
}
//Dead code, should never reach this place.
}
};
public IBinder onBind(Intent intent)
{
return null;
}
#Override
public void onCreate()
{
new Thread(runnable).start();
Notification notification = new Notification.Builder(getApplicationContext()).setContentTitle("MyService is running!").setContentTitle("(more information later)").build();
startForeground(1, notification);
Toast.makeText(getApplicationContext(), "Service created!", Toast.LENGTH_LONG).show();
}
}

Thanks, Robin.
Since you haven't implemented some parts yet I assume you just want it to run when you boot your device. Maybe take a look here. Adding an extra action in the manifest might solve your problem.

I'm unable to make WorkManager survive reboot. I want my tasks to be executed automatically even after reboot.
My Device is Realme X2 with Android 10.
WorkManager is working fine. But the moment i reboot my phone and wait for 15 mins for my tasks to be executed but it simply never executes.

Im trying to make an app that getting all notifications and do the task. But my problem is NotifycationListener service starting automaticly even i didnt call the start service. Its starting as soon as I allow the app notification access on my phone. So service starting somehow and I cant stop it. Im already try simple services they working correctly. But this one with the NotificationListener is really painful. I just want to start and stop this service by my command.
Service start by itself when I allow this (screenshot)

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {
Button startB,stopB;
Intent intent;
int count=0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
startB=(Button)findViewById(R.id.button);
stopB=(Button)findViewById(R.id.button2);
startB.setOnClickListener(new View.OnClickListener() {
#Override

intent = new Intent(MainActivity.this,MyService.class);

stopB.setOnClickListener(new View.OnClickListener() {

AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE">
<intent-filter>
<action android:name="android.service.notification.NotificationListenerService" />
</intent-filter>
></service>
</application>
And the tricky part is in the Manifest. When I delete intent-filter part and run the app. It doesn't want to notification access anymore and it doesn't start by itself. I can start and stop the service from the MainActivity with buttons. But this time the app not getting the notification.
// just delete this lines
<intent-filter>
<action android:name="android.service.notification.NotificationListenerService" />
</intent-filter>
This is an intended behavior.
When you grant notification access permission (or restart the phone) then SYSTEM is binding to your NotificationListenerService in order to send notification data.
If you override your services onBind method and log it, you will see it's being called.
I have made a simple service in android studio which should start as soon as I boot the phone. It should display atleast a TOAST Message. I am using Redmi note 4 as emulator and the service is not starting when I boot or reboot the phone. I have set the app to autostart also in settings.

MainActivity.java has no changes.
public class MainActivity extends AppCompatActivity {
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

You need to start a service, not an activity.
From
context.startActivity(serviceIntent);
To
context.startService(serviceIntent);
Alright, I have tried every solution on Stack and nothing works.My current method registers the "SmsListener" receiver from the MainActivity. All I'm trying to do is initialize the onReceive method. There are no errors; It simply isn't picking up a broadcast. What am I doing wrong? Pasting the applicable code here. Anything else that may be needed please just ask.
Update:
Here is a similar unresolved issue
Listen Android incoming SMS when Google Hangout or other app receives it
I am testing under Android 6.0.1. Target Sdk version is 22. Min Sdk is 19. It's worth noting that I just tested my original code on an LG Optimus GPro with Android 4.4.2 and it worked. It still isn't working on my Nexus with Android 6.0.1.

Try following way with highest reading priority value,
<receiver android:name=".SmsListener"
android:enabled="true"
android:exported="true"
android:permission="android.permission.READ_SMS">
<intent-filter android:priority="2147483647">
<action android:name="android.provider.Telephony.SMS_RECEIVED"/>
</intent-filter>
</receiver>
This will surely solve out your problem.
Update from below comment,
Since you are checking on Android version 6.0.1 just follow these steps,
Go to Settings,
Go to Apps
Select your Application
Choose Permissions Option
Enable SMS permission
After spending more than an hour I found that RECEIVE_SMS permission is required.
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.RECEIVE_SMS},
MY_PERMISSIONS_REQUEST_SMS_RECEIVE);
Prioirty is not required to be set. This should work.
Found a solution.
First make another app your default SMS app.
Then: Google Hangout --> Settings (Disable merged conversations) --> SMS (Disable SMS)
You are registering broadcast your in your Activity, so it won't work if your app is in background. you can remove this from your Activity and you can register it in Manifest.
ex:
<receiver android:name=".SmsListener">
<intent-filter android:priority="999">
<action android:name="android.provider.Telephony.SMS_RECEIVED"/>
</intent-filter>
</receiver>
Along with this add permission to recieve sms.
Try this, and it will work
I am implementing a simple application executing a background service, I am not able to start the service, following is my Manifest & Code, the service class is properly resolved ( reading resources ), inheriting from IntentService ( and implementing the req methods ) doesn't resolve the problem as-well...
Why does the Background service doesn't start?
any help will be appreciated.

The problem was simple, the service was actually starting but since android:process=":captureService" was specified it was starting on a separate process, one that is not connected by the debugger, either specifcally connecting to the service process, OR, omitting android:process=":captureService" resolve the problem.
