FAILED CONFIGURATION: @BeforeTest setUpDriver java.lang.NoSuchMethodError: org.openqa.selenium.os.CommandLine.executeAsync()V

Today we have noticed the below errors while running our test scripts.

So we have removed Android jars(android_webdriver_library-srcs.jar ,android_webdriver_library ) from our project Build path , then all the scripts started working fine.

We are still searching why this conflict happened and how to overcome this :)

Setup of Android WebDriver in Eclipse

Here are the Instruction for how to setup Android driver in Eclipse

1. Install  Android SDK 

Download the SDK zip file and unzip in your local computer.

Say download at “C:\android ” location

Go to unzipped folder and click on “Android SDK Manager” and install the following:

         a.Tools

         b.Extras

         c.Android API’s as per your choice (Say Android 2.2 , Android 4.0)

2. Install the ADT Plugin for Eclipse-

Goto Help > Install New Software....>> Add

https://dl-ssl.google.com/android/eclipse/

3.Configure ADT Plugin

Window > Preferences...>>Android

Set the SDK location to where is your Android SDK has been installed.

Location will be something like:  C:\android\android-sdk-windows

4. Add the new AVD

In Eclipse goto Window >>AVD Manager>>

Create new AVD by clicking on “New” button.(Give the AVD  name  and select the Target)

5.Now download the Android APK 

http://code.google.com/p/selenium/downloads/detail?name=android-server-2.21.0.apk&can=2&q=

Copy the file and paste it in the “Platform-tools” folder of the unzipped Android SDK.

Location will be something like “C:\android\android-sdk-windows\platform-tools “

6. Now start the Android AVD (Which has been created in Step 4) by following below in your Eclipse
Window >>AVD Manager>> Select the created AVD and click on “Start”

7.  Find the installed emulator device id .
open the command prompt ( cmd ) and run the following command 

adb devices

Emulator device id will be something like “emulator-5554”

8. Now from the command prompt, go to the “Platform-tools” folder of the unzipped Android SDK

cd "C:\android\android-sdk-windows\platform-tools"

9. Install the Android server by running the following command

adb -s <<emulator-id>> -e install -r  android-server-2.21.0.apk

10. Start the Android WebDriver application by running the following command

adb -s <<emulator-id>> shell am start -a android.intent.action.MAIN -n org.openqa.selenium.android.app/.MainActivity -e debug true

11. Now setup the port forwarding in order to forward traffic from the host machine to the emulator by running the following command

adb -s <<emulator-id>> forward tcp:8080 tcp:8080
