Appium - Create Session - Error: Either Jsonwp Or W3c Capabilities Should Be Provided

I am unable to get Appium to start an Android session and did not find anything related to the error message I am getting when I searched online. When I run my test Appium dumps th

Solution 1:

Replace ApplicationName> Absolute to either App or (appPackage and appActivity)

//Either add following line in the DesiredCapabilitiescapabilities.setCapability(MobileCapabilityType.App, "Path to your apk file");

//OR add following two capabilities if the app is already installed in the testing devicecapabilities.setCapability("appPackage", "app package name");
capabilities.setCapability("appActivity, "app activity name");

@Dave Thomas, hi.

Considering official spec says that

• JSONWP Spec Required capabilities have higher priority than desired capabilities and must be set for the session to be created
• W3C Spec capabilities.alwaysMatch must be set for session to be created; capabilities.firstMatch must match at least one (the first one to match will be used)

I think You should dig into capabilities set-up. Let me share piece of code that might be helpful for You:

package io.mytestproject.appium.tests;
        import io.appium.java_client.android.AndroidDriver;
        import io.appium.java_client.remote.AndroidMobileCapabilityType;
        import io.appium.java_client.remote.MobileCapabilityType;
        import io.testproject.appium.pom.tests.pages.LoginPage;
        import io.testproject.appium.pom.tests.pages.ProfilePage;
        import org.openqa.selenium.Platform;
        import org.openqa.selenium.remote.DesiredCapabilities;
        import java.net.URL;
        publicclassPositiveLoginTest {
            privatefinalstaticStringAPP_PACKAGE_NAME="io.mytestproject.demo";
            privatefinalstaticStringAPP_ACTIVITY_NAME=".MainActivity";

   publicvoidsetup()throws Exception {
                // Prepare Appium sessionDesiredCapabilitiescapabilities= DesiredCapabilities.android();
                capabilities.setCapability(MobileCapabilityType.PLATFORM_NAME, Platform.ANDROID);
                capabilities.setCapability(MobileCapabilityType.UDID, "YOUR_DEVICE_UDID");
                capabilities.setCapability(MobileCapabilityType.NO_RESET, false);
                capabilities.setCapability(AndroidMobileCapabilityType.APP_PACKAGE, APP_PACKAGE_NAME);
                capabilities.setCapability(AndroidMobileCapabilityType.APP_ACTIVITY, APP_ACTIVITY_NAME);
                // Initialize driverAndroidDriverdriver=newAndroidDriver(newURL("http://0.0.0.0:4723/wd/hub"), capabilities);

    ......        }
        }

Please also see this article to understand the difference between web and mobile test automation drivers and corresponding capabilities.

And also, providing the whole listing of Appium Desired Capabilities

Hope this helps for You, Regards, Eugene
