How to press the keys in mobile keyboard

Hi, I’m doing mobile automation with robot framework & Appium. I want to enter the texts & numbers in my application by pressing the mobile keyboard (Screenshot_01).

This is what I have so far,

`*** Settings ***

Library AppiumLibrary
Resource /some/path/Variables.robot

*** Test Cases ***

TC_01_Login with valid details
Open Application http://localhost:4723/wd/hub platformName=Android deviceName=emulator-5554 app=C:/APK/APK_File_Name.apk automationName=Uiautomator2
sleep 10s

# Skip Button
click element   //android.widget.TextView[@text="Skip"]
sleep  5s

# Enter the Name
input text      ${Locator_Name}     xxxxx
sleep  5s
# Continue Button
click element   ${Continue_Button}
sleep  10s

# Enter the Mobile Number
click element   ${Locator_Mobile}
sleep  25s

#############################
#Try 1

# Click No. 0 from the mobile keyboard
click element    //android.widget.LinearLayout[@text="0"]
sleep  1s

#############################
#Try 2

# Click No. 0 from the mobile keyboard
PRESS KEYCODE     None    0
sleep  2s

#############################

# Next Button
click element    ${Next_Button}`

Here, First I tried as “Try 1”, and get the below error;
ValueError: Element locator ‘//android.widget.LinearLayout[@text=“0”]’ did not match any elements.

Then I deleted the first method and tried as “Try 2”. But it closed the application so that I couldn’t complete the scenario.

Please help to solve this issue. Any guidance and advice will be greatly appreciated!

Have you know the answer yet? Would you mind to let me know How to press the enter keys in mobile keyboard, please.

@KonraweePra, In this application, here we used the default keyboard. So, I couldn’t press the keys using the “Click Element” and “Press Keycode” keywords. But I was able to do it by clicking the coordinates.
Here is a sample example, maybe it will be helpful to you.

## Enter the keys
# Click on the space button
AppiumLibrary.click element at coordinates    748    2603
sleep  2s
# Click on the letter "g"
AppiumLibrary.click element at coordinates    718    2262
sleep  2s

# Press No. 0
AppiumLibrary.click element at coordinates    532    2599
sleep  1s
# Press No. 7
AppiumLibrary.click element at coordinates    186    2465
sleep  1s
