tap and press using appium

Some important points

1. TouchAction class can be used to do tap, press and long press operation
2. We can find the Point of Source and Destination element using getLocation method
3. In same way, we can do this action in iOS as well

Below hypothetical code demonstrates how you can perform tap, press and long press actions in appium.

package org.softpost.android.simulator;

import io.appium.java_client.MultiTouchAction;
import io.appium.java_client.TouchAction;
import io.appium.java_client.android.AndroidDriver;
import io.appium.java_client.android.AndroidElement;
import io.appium.java_client.touch.WaitOptions;
import io.appium.java_client.touch.offset.PointOption;
import org.junit.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;

import java.net.URL;
import java.time.Duration;
import java.util.concurrent.TimeUnit;
