title: Enter "Enter key" in Appium Testing
body: <p>How to send/press <strong>Enter</strong> key from soft keyboard in Appium in Android Automation testing? <br/>
  I tried several options, but none of them are working - instead of pressing the key, they are clearing the text entered in text area. Below is the code (in JAVA Language):<br/></p>
  
  <pre><code>String app_package_name = "abc.xyz.android";
  
  DesiredCapabilities capabilities = new DesiredCapabilities();
  capabilities.setCapability("platformName", "Android");
  capabilities.setCapability("deviceName", "Nexus_5X_API_23");
  capabilities.setCapability("platformVersion", "6.0");
  capabilities.setCapability("appPackage", app_package_name);
  capabilities.setCapability("appActivity", app_package_name + ".activity.StartupActivity_");
  
  String url = "http://127.0.0.1:4723/wd/hub";
  AndroidDriver driver = new AndroidDriver(new URL(url), capabilities);
  driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
  
  By password = By.id(app_package_name_with_id + "et_password");
  WebElement enterPassword = driver.findElement(password);
  enterPassword.click();
  driver.getKeyboard().sendKeys("12345");
  
  driver.getKeyboard().sendKeys(Keys.ENTER); // THIS IS NOT WORKING.
  driver.getKeyboard().sendKeys(Keys.RETURN); // THIS IS ALSO NOT WORKING.
  driver.pressKeyCode(AndroidKeyCode.ENTER); // THIS IS ALSO NOT WORKING.
  driver.pressKeyCode(AndroidKeyCode.KEYCODE_NUMPAD_ENTER); // SAME HERE.
  enterPassword.sendKeys(Keys.ENTER); // SAME HERE.
  </code></pre>
  
  <p>Please if anyone can help me achieve it?</p>
