How to receive ACTION_SCREEN_OFF with a "always running" service

I want to create an app that set/reset a timer to reproduce a song if the mobile spend 8 hours with the screen off.
I want to create a service that receive ACTION_SCREEN_OFF, but the problem is that when the app is killed from recent apps, the service is killed. I try with START_STICKY but the service is not restarted (onCreate is called sometimes but not onStart Command). I try to set in Manifest but the receiver must be register.
By now I only want that receiver detect ACTION_SCREEN_OFF.
I Have this code:
MainScreen.java (MainActivity)
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
public class MainScreen extends Activity implements View.OnClickListener{
public static final String MSG_TAG = "NoSleepMore";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_screen);
findViewById(R.id.start_service_button).setOnClickListener(this);
findViewById(R.id.stop_service_button).setOnClickListener(this);
}
#Override
public void onClick(View v){
Intent intent = new Intent(getApplicationContext(), LockService.class);
switch (v.getId()) {
case R.id.start_service_button:
Log.e(MSG_TAG,"Service started");
//starts service for the given Intent
startService(intent);
break;
case R.id.stop_service_button:
Log.e(MSG_TAG,"Service stopped");
//stops service for the given Intent
stopService(intent);
break;
}
}
}
LockService.java
import android.app.Service;
import android.content.BroadcastReceiver;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.IBinder;
import android.util.Log;
public class LockService extends Service {
#Override
public IBinder onBind(Intent arg0) {
Log.i(MainScreen.MSG_TAG, "onBind()" );
return null;
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.i(MainScreen.MSG_TAG, "Service Created");
/* Filtrar Acciones Capturadas */
final IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
filter.addAction(Intent.ACTION_SCREEN_OFF);
filter.addAction(Intent.ACTION_USER_PRESENT);
// Listener
final BroadcastReceiver mReceiver = new ScreenReceiver();
// Registar Listener
registerReceiver(mReceiver, filter);
return Service.START_STICKY;
//return super.onStartCommand(intent, flags, startId);
}
#Override
public void onCreate() {
Log.i(MainScreen.MSG_TAG, "onCreate()");
}
#Override
public void onDestroy() {
Log.i(MainScreen.MSG_TAG, "onDestroy()");
}
}
ScreenRecive.java
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
public class ScreenReceiver extends BroadcastReceiver {
#Override
public void onReceive(final Context context, final Intent intent) {
Log.i(MainScreen.MSG_TAG,"OnReceive->");
// Log Handel
if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
// do whatever you need to do here
Log.i(MainScreen.MSG_TAG,"Screen action OFF");
} else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {
// and do whatever you need to do here
Log.i(MainScreen.MSG_TAG,"Screen action ON");
}else if(intent.getAction().equals(Intent.ACTION_USER_PRESENT)){
Log.e(MainScreen.MSG_TAG,"Action UserPresent");
}
}
}

avoid of send null from destroyed activity to restarted service

I want to programing app for data track in background , so I use service .
I want to write a program that monitors all data sent and received by the device, and when the total volume of received or received messages reaches a specified value, the Internet device is turned off.
So I used the following code to monitor the data:
 
mStartRX = TrafficStats.getTotalRxBytes ();
mStartTX = TrafficStats.getTotalTxBytes ();
And I used the services to work on the background in the background.
To specify the download or upload limit from the user with edittext, I requested this limit in mainactivity and send this value to the service.
The problem is when: When I destroy the program, I will restart the service and get the NULL value and the program crashes.
My application code:

please help me ...

The problem is with this line
public long dl=MainActivity.DLL;
You're referring to a variable in the Activity, surly when the Activity is destroyed, this variable is no longer in scope, thus you get Null Exception.
You must get this value using the intent.
The other problem is that you can't prevent any service from being killed by the system except foreground services which need to show a notification to the user. But this is not suitable for your situation.
Therefore, the best approach for you is to check whether intent is null or not. If it is not null, you get the value and save it into Preferences or Database or somewhere, if it is null, you retrieve the value from where you stored it before.

Problem
ToolBar on AdminLogin does not allow me to return to LoginActivity when I select the back Button
Admin Login does not work despite entering the hardcoded input for the Admin Name and Password. After clicking on the Login button, the app prompts out a White layout for a few seconds I am brought back to the StartActivity and the Toast message does not show "Failed Login".
SOLUTION
The problem was because the "AdminActivityClass" had
#Override
public void onStart() {
super.onStart();
FirebaseUser currentUser = mAdminAuth.getCurrentUser();
if(currentUser == null){
sendUserToStartPage();
}
}
private void sendUserToStartPage(){
Intent intentStart = new Intent(AdminActivity.this, StartActivity.class);
startActivity(intentStart);
finish();
}
Since the Admin login was hardcoded, the currentUser within the FirebaseUser currentUser = mAdminAuth.getCurrentUser(); was set to null. This caused the activity to be sent back to the start page (sendUserToStartPage();)

After posting your full set of code, you should be doing the following.
comment out the sendUserToStartPage(); inside of the currentuser == null and then try.
why? Because the user IS null. why? because you hard coded it into the code. The user admin with password admin does not exist in your Firebase (and if it does, you never checked it prior) so when you sign in, you do not create a session for admin, therefore the current user is null.
try doing this
if ("admin".equals(adminLoginID)) {
if ("admin".equals(adminLoginPassword)) {
//goto activity
}
} else {
//not admin
}
this might be better actually
if (("admin".equals(adminLoginID)) && ("admin".equals(adminLoginPassword))) {
//goto activity
} else {
//not admin
}
or even this....
if (("admin".equals(jAdminID.getText().toString().trim())) && ("admin".equals(jAdminPassword.getText().toString().trim()))) {
//goto activity
} else {
//not admin
}
Try this example in the manifest.
Youre manifest for the activities are missing a theme.
Also, its missed the meta-data.
<activity
android:name=".Leagues.CreateLeague"
android:label="Create League"
android:parentActivityName=".MainActivity"
android:screenOrientation="portrait"
android:theme="#style/AppTheme2">
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.aaa.bbb.MainActivity" />
</activity>

Try like this smartly
take a String variable globally and declare and intialise them
in next step you need to add validations
String str_admin="admin";
if ((str_admin.equals(adminLoginID)) && (str_admin.equals(adminLoginPassword))) {
//pass reference of activity which you want to open it
} else {
//not admin
}
Happy to help yoh

How to start service in dialer (default or stock dialer) of android

I want start a service when my dialer (default or stock dialer) open. My service just toasts a message. How to start the service for dialer. The startService command is working in MainActivity, but it is not working while a dialer is open.
My code is shown below:

}
}
This code is not working. The service starting when the startService calling in MainActivity. But when a dialer open it not working.

I think maybe you can try changing getApplication () to MainActivity.this.
And I think you need to jump from the dialer to MainActivity to get the service started

Where am I wrong with broadcasting info from Java and receiving in Unity?

So I just started working on this project and part of it is sending packages of information from an app in Java to another Unity app.
I have been trying to follow this tutorial but I have problems getting it to work and even somewhat understanding it a bit since I have not worked with Java before.
Here is the current code I have so far.
