I run my test, there is no error report in appium or eclipse but only my app failed. to execute the evaluate result.
here is my code:
package Practice;

import java.net.MalformedURLException;
import java.net.URL;
import org.openqa.selenium.By;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.interactions.Actions;
import org.openqa.selenium.remote.DesiredCapabilities;
import io.appium.java_client.AppiumDriver;
import io.appium.java_client.MobileElement;
import io.appium.java_client.android.AndroidDriver;

public class clickAbout {

public static void main(String[] args) throws InterruptedException {
    
    //Set the Desired Capabilities
    DesiredCapabilities caps = new DesiredCapabilities();
    caps.setCapability("deviceName", "Android device");
    caps.setCapability("udid", "emulator-5554");//Give Device ID of your mobile phone
    caps.setCapability("platformName", "Android");
    caps.setCapability("platformVersion", "8.0.1");
    caps.setCapability("appPackage", "com.transcomputing.cali");
    caps.setCapability("appActivity", "com.transcomputing.cali.MainActivity");
    caps.setCapability("autoWebview", true);        
    caps.setCapability("showChromedriverLog",true);  
    caps.setCapability("unicodeKeyboard", true);
    
    //caps.setCapability("enablePerformanceLogging",true);
                
    try {
            AppiumDriver<MobileElement> driver = new AndroidDriver<MobileElement>(new URL("http://0.0.0.0:4723/wd/hub"), caps);
                            
            //driver.findElement(By.cssSelector(".item-block")).click();
            driver.findElement(By.xpath("//*[@id=\'btn-about\']/div[1]/div")).click();
            driver.findElement(By.cssSelector("body > ion-app > ng-component > ion-nav > ng-component > ion-tabs > page-about > ion-header > ion-navbar > button")).click();
            driver.findElement(By.xpath("//*[@id=\'btn-resources\']/div[1]/div")).click();
            driver.findElement(By.xpath("//*[@id=\'tab-t0-0\']/ion-icon")).click();
            driver.findElement(By.xpath("//*[@id=\'btn-settings\']/div[1]/div")).click();
            driver.findElement(By.xpath("//*[@id=\'tab-t0-0\']/ion-icon")).click();
            driver.findElement(By.xpath("//*[@id=\'btn-evaluate\']/span")).click();
            
            driver.findElement(By.xpath("//*[@id=\'select-8-0\']/span")).click();
            JavascriptExecutor je = (JavascriptExecutor) driver;
           
            WebElement element = driver.findElement(By.xpath("/html/body/ion-app/ion-modal/div/ng-component/ion-content/div[2]/ion-list/button[29]/div[1]/div"));
           
            je.executeScript("arguments[0].scrollIntoView(true);",element);
          
            driver.findElement(By.xpath("/html/body/ion-app/ion-modal/div/ng-component/ion-content/div[2]/ion-list/button[29]/div[1]/div")).click();
          

          WebElement ele = driver.findElement(By.xpath("//*[@id=\'tabpanel-t0-1\']/page-evaluate-test-results/ion-content/div[2]/wrap-card-tablet/form/ion-list/ion-item-group[2]/ion-item[1]/div[1]/div/ion-input/input"));
          //((JavascriptExecutor) driver).executeScript("arguments[0].scrollIntoView(true);", ele);
          
          JavascriptExecutor jse = (JavascriptExecutor)driver;
          jse.executeScript("arguments[0].value='2222';", ele);
          
          
          driver.findElement(By.xpath("//*[@id=\'tabpanel-t0-1\']/page-evaluate-test-results/ion-content/div[2]/wrap-card-tablet/form/ion-list/ion-item-group[4]/ion-item[1]/div[1]/div/div/div/div[2]/ion-segment/ion-segment-button[1]/div[1]")).click();
          driver.findElement(By.xpath("//*[@id=\'tabpanel-t0-1\']/page-evaluate-test-results/ion-content/div[2]/wrap-card-tablet/form/ion-list/ion-item-group[5]/ion-item[1]/div[1]/div/ion-select/div[1]")).click();
          
          
          Actions a=new Actions(driver);
        		a.moveToElement(driver.findElement(By.xpath("/html/body/ion-app/ion-popover/div/div[2]/div/ng-component/ion-list/ion-item[1]/div[1]/ion-radio"))).click().build().perform();
           driver.findElement(By.xpath("//*[@id=\'tabpanel-t0-1\']/page-evaluate-test-results/ion-content/div[2]/wrap-card-tablet/form/ion-grid/ion-row/ion-col[2]/button/span")).click();
        		
         
 
    } catch (MalformedURLException e) {
        System.out.println(e.getMessage());
    }
    
    
}

}
I can enter value into it by javascript method, but the result is not recognizeresult

if I use method as driver.findElement(By.xpath("/html/body/ion-app/ion-modal/div/ng-component/ion-content/div[2]/ion-list/button[29]/div[1]/div")).click();
the error report as unknown error: Element

is not clickable at point (159, 554). Other element would receive the click:
I am using java, appium 1.7.2

I would prefer to use relative xpaths, instead of absolute. Please try to make an effective xpath then use.


this is the keyboard, it is html5 keyboard, not accept sendkeys, has to click on keyboard.

So, you have to click on any of the keys here ?

Please send me the screenshot of DOM

do you mean this one?

I am running into the same issue with numeric keyboard. Please share if there is a solution for this.
