I made an application running in the background, and I want to add a function to measure the slide on the screen. I'll leave you the code for both, and someone can help me. I'm a beginner and I've been looking all over trying to solve this without results.

I know the post is too long, but I did not know how to shorten it so you can understand it.

The code for running the application in the background

App.java

package com.codinginflow.foregroundserviceexample;

import android.app.Application;
import android.app.NotificationChannel;
import android.app.NotificationManager;
import android.os.Build;


public class App extends Application 
public static final String CHANNEL_ID = "exampleServiceChannel";

@Override
public void onCreate() 
 super.onCreate();

 createNotificationChannel();


private void createNotificationChannel() 
 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) 
 NotificationChannel serviceChannel = new NotificationChannel(
 CHANNEL_ID,
 "Example Service Channel",
 NotificationManager.IMPORTANCE_DEFAULT
 );

 NotificationManager manager = 
getSystemService(NotificationManager.class);
 manager.createNotificationChannel(serviceChannel);
 

AndroidManifest.xml

ExampleService.java

package com.codinginflow.foregroundserviceexample;

import android.app.Notification;
import android.app.PendingIntent;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.support.annotation.Nullable;
import android.support.v4.app.NotificationCompat;

import static com.codinginflow.foregroundserviceexample.App.CHANNEL_ID;


public class ExampleService extends Service 

@Override
public void onCreate() 
 super.onCreate();


@Override
public int onStartCommand(Intent intent, int flags, int startId) 
 String input = intent.getStringExtra("inputExtra");

 Intent notificationIntent = new Intent(this, MainActivity.class);
 PendingIntent pendingIntent = PendingIntent.getActivity(this,
 0, notificationIntent, 0);

 Notification notification = new NotificationCompat.Builder(this, 
 CHANNEL_ID)
 .setContentTitle("Example Service")
 .setContentText(input)
 .setSmallIcon(R.drawable.ic_android)
 .setContentIntent(pendingIntent)
 .build();

 startForeground(1, notification);

 return START_NOT_STICKY;


@Override
public void onDestroy() 
 super.onDestroy();


@Nullable
@Override
public IBinder onBind(Intent intent) 
 return null;

MainActivity.java

package com.codinginflow.foregroundserviceexample;

import android.content.Intent;
import android.support.v4.content.ContextCompat;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;

public class MainActivity extends AppCompatActivity 
private EditText editTextInput;

@Override
protected void onCreate(Bundle savedInstanceState) 
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);

 editTextInput = findViewById(R.id.edit_text_input);


public void startService(View v) 
 String input = editTextInput.getText().toString();

 Intent serviceIntent = new Intent(this, ExampleService.class);
 serviceIntent.putExtra("inputExtra", input);

 ContextCompat.startForegroundService(this, serviceIntent);


public void stopService(View v) 
 Intent serviceIntent = new Intent(this, ExampleService.class);
 stopService(serviceIntent);

Code for sliding measurement

Point p1;
Point p2;

View view = new View(this);

view.setOnTouchListener(new View.OnTouchListener() 
 public boolean onTouch(View v, MotionEvent event) 
 if(event.getAction() == MotionEvent.ACTION_DOWN)
 p1 = new Point((int) event.getX(), (int) event.getY());
 else if(event.getAction() == MotionEvent.ACTION_UP)
 p2 = new Point((int) event.getX(), (int) event.getY());

 return false;
 
);

Can someone call me this code in my app?
