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);

    }

}

}

            .setContentTitle("Example Service")

            .setContentText(input)

            .setSmallIcon(R.drawable.ic_android)

    super.onDestroy();

    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?
