Not able to identify the MenuList button via Xpath's


I am using appium version 1.8.2. When I am trying to find element(usually by xpath), but getting below error:
javax.xml.transform.TransformerException: Expected ], but found: ,
For documentation on this error, please visit:

*** Element info: {Using=xpath, value=//android.widget.TextView[contains[@content-desc,‘Volume’]]}

and also when i try to inspect the element via Appium Desktop, it is closes unexpectedly.

FYI, I am trying to inspect a Menu List button.

Below are the other xpath’s I have tried.
MobileElement menuListBox = driver.findElement(By.xpath("//*[android.widget.TextView[@resource-id=‘com.myapp:id/action_more’]]"));

Actions action = new Actions(driver);

Can anyone please tell me what needs to be done
