how to resolve Appium bad parameters error - automated-tests

Question

I am stuck at the error when the appium server shows error
[MJSONWP] Bad parameters: BadParametersError: Parameters were incorrect. We wanted {"required":["desiredCapabilities"],"optional":["requiredCapabilities","capabilities","sessionId","id"]} and you sent ["desiredCapabilities","requiredCapabilities","capabilities","alwaysMatch","firstMatch"]
In the eclipse it shows error
org.openqa.selenium.SessionNotCreatedException: Unable to create new remote session. desired capabilities = Capabilities [{app=C:\Users\Admin\workspace\Sling_App\src\app-dev-debug.apk}], required capabilities = Capabilities [{}]
I have been using 5.0.0 and also 4.1.2 client jar
Tried with Selenium 3 , 3.3
Appium Server I tried on are 1.6.2 , 1.6.3 and latest 1.6.4
Nothing Solves the problem ,
I read most of the articles related to this , but of no use
Please tell if any 1 has found solution to thisenter image description here

Answer 1

In ideal case we need to pass 6 capabilities(for APK testing) as below,
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("deviceName","ANDROID");
capabilities.setCapability("platformVersion", "5.1");
capabilities.setCapability("platformName",Constant.appPlatform);
capabilities.setCapability("app", app.getAbsolutePath());
capabilities.setCapability("appPackage", Constant.appPackage);
capabilities.setCapability("appActivity",Constant.appActivity);
Also initiate appium webdriver instead of Android as below,
AppiumDriver driver = new AndroidDriver(new URL("http://127.0.0.1:4727/wd/hub"), capabilities);
I am using appium 1.6.4 and java client 4.12 with selenium stand alone 2.53.1.
AppPackage/AppActivity are required for simulator also.
Hope this helps you.
Thanks.
