Appium error: Logcat capture failed: spawn ENOENT With Android Studio

Question

I am running a simple Calculator test for Android Emulator using Appium + WebDriver in Android Studio. I have manually started Appium Server and Android Emulator and then running test using TestNG.xml.

Here is my sample WebDriver code -

package com.example.user.mysampleapp2;

/**

import java.net.MalformedURLException;
import java.net.URL;
import java.util.concurrent.TimeUnit;
import org.testng.annotations.*;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.remote.CapabilityType;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;

import io.appium.java_client.remote.MobileCapabilityType;
import io.appium.java_client.remote.MobilePlatform;

public class SampleTests {
    public WebDriver driver;

    @BeforeClass
    public void setUp() throws MalformedURLException {
        // Created object of DesiredCapabilities class.
        DesiredCapabilities capabilities = new DesiredCapabilities();

        // Set android deviceName desired capability. Set your device name.
        capabilities.setCapability(MobileCapabilityType.DEVICE_NAME, "Nexus_6_API_25");

        // Set BROWSER_NAME desired capability. It's Android in our case here.
        capabilities.setCapability(MobileCapabilityType.BROWSER_NAME, "Android");

        // Set android VERSION desired capability. Set your mobile device's OS version.
        capabilities.setCapability(MobileCapabilityType.VERSION, "7.1.1");

        // Set android platformName desired capability. It's Android in our case here.
        capabilities.setCapability(MobileCapabilityType.PLATFORM_NAME, MobilePlatform.ANDROID);

        // Set android appPackage desired capability. It is
        // com.android.calculator2 for calculator application.
        // Set your application's appPackage if you are using any other app.
        capabilities.setCapability("appPackage", "com.android.calculator2");

        // Set android appActivity desired capability. It is
        // com.android.calculator2.Calculator for calculator application.
        // Set your application's appPackage if you are using any other app.
        capabilities.setCapability("appActivity", "com.android.calculator2.Calculator");

        // Created object of RemoteWebDriver will all set capabilities.
        // Set appium server address and port number in URL string.
        // It will launch calculator app in android device.
        driver = new RemoteWebDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
    }

    @Test
    public void testFirstCalculator() {

        // Click on DELETE/CLR button to clear result text box before running test.
        driver.findElements(By.xpath("//android.widget.Button")).get(0).click();

        // Click on number 2 button.
        driver.findElement(By.name("7")).click();

        driver.manage().timeouts().implicitlyWait(30,TimeUnit.SECONDS);
    }

    @AfterClass
    public void End() {
        driver.quit();
    }
}

When I run this from Android Studio I get below Appium Error.

I have gone through all the available posts on forum and also Set ANDROID_HOME variable with SDK path in Android Studio Run configurations (Android_Home). Still I am receiving this error.

Any help?

Thanks, Chandresh Parmar

Answer 1

You can follow these answers to fix ANDROID_HOME env variable being set. In the meantime, I suggest to install appium-doctor and check what is missing in your environment setup prior appium tests execution.

In your case:

npm install appium-doctor -g
appium-doctor --android

And response you expect to get is:

### Diagnostic starting ###
✔ The Node.js binary was found at: /usr/local/bin/node
✔ Node version is 7.9.0
✔ ANDROID_HOME is set to: /Users/<user>/Library/Android/sdk
✔ JAVA_HOME is set to: /Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home
✔ adb exists at: /Users/<user>/Library/Android/sdk/platform-tools/adb
✔ android exists at: /Users/<user>/Library/Android/sdk/tools/android
✔ emulator exists at: /Users/<user>/Library/Android/sdk/tools/emulator
✔ Bin directory of $JAVA_HOME is set
### Diagnostic completed, no fix needed. ###

Fix all the x marks and good luck

Answer 2

From the error logs, you can clearly see that, ANDROID_HOME environment variable is not set.

For example : You have installed the Android SDK in "C:\Users\YourUserName\AndroidSDK" then the value of ANDROID_HOME path will be the same path.

Just add new environment variable with name as ANDROID_HOME and value as your path.

And also your appium version very old(1.4.16). I suggest you to upgrade it to 1.6.3 which is very stable version of appium as of now
