An element could not be located on the page using the given search parameters (Appium 1.13.0) - appium-android

Question

I am working on Automation for Android App. While running the script, Appium unable to find the elements. I tried using Id, Xpath. Please help me with this...
Android version: 5.1.1 & 9
Appium Version: 1.13.0
Maven Project
#Test
public void login() {
driver.findElement(By.xpath("//com.vehito.vehitoplus[contains(#resource-id,'phone')]")).sendKeys("9632642105");
driver.findElement(By.id("com.vehito.vehitoplus:id/sign_in_button")).click();
}
Actual Result:
Encountered internal error running command: NoSuchElementError: An element could not be located on the page using the given search parameters

Answer 1

This error said that UIAutomator couldn't able to find that Element.
I found 2 problem with your Xpath code:
1- Replace , with = after resource-id.
2- You use packageName (com.vehito.vehitoplus) instead of the class name.
You can find the exact class name of the element with UIAutomator Viewer:
(Android SDK Dir)\tools\bin\uiautomatorviewer.bat
I mean you may use this: (If the element's class name be: android.widget.EditText )
driver.findElement(By.xpath("//android.widget.EditText[contains(#resource-id='phone')]")).sendKeys("9632642105");
In my experience, I found that By. library (XPath or ID) is not working well with #contains. So it's better if you use exact attributes.
e.g.
driver.findElement(By.id("com.vehito.vehitoplus:id/sign_in_button")).sendKeys("9632642105");
I hope this helps. If not, please provide a screenshot from the page and also UIAutomator viewer screenshot of this input element.
