To take screenshot in Android and iOS

[Amit Rawat]

Can we take screenshots for iOS and Android app screens. I could see some comments in Git "Added support for screenshots for Android."   but I am not sure how to use it in my code.

I am using java for both Android and iOS automation. I would really appreciate if any one can help me on this.

Android screenshots are a work in progress.

I also run into this problem.

I am looking into using Appium to further my UI testing, are there demonstrations or tutorials that would show how to capture screens?

Or is the screencapture code part of the Appium codebase, and, if so would I use a Selenium screen capture function in my automation to take screens?

[bootstrap online]

The Selenium screencapture command should work. In Ruby it's
@driver.save_screenshot png_save_path

I have tried taking the screenshot of android hybrid app with selendroid and ios native/hybrid apps which works well .

But, when I try to take screenshot of android native app by setting device as 'android' , the screenshot request doesn't even reach appium.

My test fails with the following message.

java.lang.ClassCastException: org.openqa.selenium.remote.RemoteWebDriver cannot be cast to org.openqa.selenium.TakesScreenshot

Please find below the java code which I used.

##################Java code#################################

DesiredCapabilities capabilities = new DesiredCapabilities();

capabilities.setCapability("device", "android");

 // Take the Screen shot and store it in a file

        org.openqa.selenium.WebDriver augmentedDriver = new Augmenter().augment(webDriver);

        File screenshot = ((TakesScreenshot) augmentedDriver).getScreenshotAs(OutputType.FILE);

        // the name of the file

        String filename = "screenshot.png";

        FileUtils.copyFile(screenshot, new File(filename));

That sounds like a Java-specific issue. Screenshots also work in the javascript bindings (see Appium's test suite for example).

[Jason Carr]

Yeah the bindings don't all work *exactly* the same way. It's possible that we're not 100% compatible with the java bindings, or that the java bindings are broken, or that the code is wrong. Looking at the code, I think you're doing it the right way. Maybe someone else has some insight into how to do this with Java?

[Brian]

Thanks for the help.

Hi,

I have tried taking screen shots of android native app and it works fine, though i struggled a lot to get it work. I have done it in both java and C#. Here's the code in c#

 try

                    {

                        String base64 = rm.executescript(DriverCommand.Screenshot, null).Value.ToString();

                        byte[] data = Convert.FromBase64String(base64);

                        using (var stream = new MemoryStream(data, 0, data.Length))

                        {

                            Image image = Image.FromStream(stream);

                            image.Save(filePath + "\\" + imageName);

                        }

                    }

                    catch (Exception e)

                    {

                        Console.Write(e.Message);

                    }

here "rm" is the object for class that extends RemoteWebDriver and overrides the method "executescript".

Hope it works for you :)

Hi Ritika,

Thanks a lot for your response.

I have tried a few based on your c# code and trying to work out similar in java.But still end up getting the same ClassCatException.

Would greatly appreciate if you could post your java code.

[Dan Cuellar]

Sounds like this might be an appium bug, can someone 100% confirm screenshot does not work with java?

[bootstrap online]

ClassCastException is a user error and not an Appium bug.

Hi Ritika,

Glad to hear that someone has got capturing screenshots working in c#. I am using the ScreenShotRemoteWebDriver.cs implemented by ?? a while back that casts ITakeScreenShot to Remotedriver but I can't get screenshot capture to work. It works on mobile browsers but for some reason it doesn't work on Native Apps. I tried to incorporate your code but I still could get it to work, could you point out where I am doing it wrong;

        public Screenshot GetScreenshot()

        {

            // Get the screenshot as base64.

            Response screenshotResponse = this.Execute(DriverCommand.Screenshot, null);

            string base64 = screenshotResponse.Value.ToString();

            // ... and convert it.

            return new Screenshot(base64);

        }

    }

}

Where I am using the class

Screenshot screenshot = ((ITakesScreenshot)driver).GetScreenshot();

            string ss = screenshot.AsBase64EncodedString;

            byte[] screenshotAsByteArray = screenshot.AsByteArray;

             screenshot.SaveAsFile("//location+imagename", System.Drawing.Imaging.ImageFormat.Jpeg);

As i said this works on mobile browsers

[Guilherme Tramontina]

I've just posted my findings on github (https://github.com/appium/appium/issues/708#issuecomment-19996799). Pasting my comment here:

Using the Java web driver, I was getting a ClassCastException as someone reported on google groups (https://groups.google.com/forum/#!searchin/appium-discuss/screenshot/appium-discuss/A6kAET0C7nc/_I7rszrh8YkJ) when augmenting the driver to be able to take screenshots. I dug a little bit and found that my remote web driver was not being augmented with the TakesScreenshot interface, and then I noticed that the capability for Android (app/android.js) is set to takesScreenshots: true, while the capability constant is takesScreenshot (no 's' at the end).
So I went ahead and changed it locally to see if I could make it work. I ended up with a different error. Now it augments my driver, but I get the following error: org.openqa.selenium.remote.SessionNotFoundException: Session ID is null
Has anyone ever got screenshots working with webdriver for Java and Android?

[Ajith V L]

I am also having the same issue as Guilherme. Screenshot works on iOS but it does not work on Android for native apps. I am getting the exception "

[bootstrap online]

Screenshots are working for me in Ruby so I think it's an issue with
the Java bindings.

[Dan Cuellar]

Yeah, in .NET you have to roll your own Screenshot methods because for some reason they are not in the RemoteWebDriver class.

[Dan Cuellar]

I submitted a patch to the Selenium project about a year ago and no one has merged

[Adriano Bonat]

I've sent a pull request to fix this issue:

https://github.com/appium/appium/pull/829

The correct capability name is "takesScreenshot", in the singular.

[W]

Could you point in in the right direction, I am using the following but the function is not detecting a native app it works for mobile browsers. This is webdriver c#

  public Screenshot GetScreenshot()

        {

            // Get the screenshot as base64.

            Response screenshotResponse = this.Execute(DriverCommand.Screenshot, null);

            string base64 = screenshotResponse.Value.ToString();

            // ... and convert it.

            return new Screenshot(base64);

        }

    }

}

Where I am using the class

Screenshot screenshot = ((ITakesScreenshot)driver).GetScreenshot();

            string ss = screenshot.AsBase64EncodedString;

            byte[] screenshotAsByteArray = screenshot.AsByteArray;

             screenshot.SaveAsFile("//location+imagename", System.Drawing.Imaging.ImageFormat.Jpeg);

My pull request got merged but there isn't a new release of appium with it, you can try out with appium from their git repo or wait the next release (current version in npm is 0.7.3).

Hi, I'm also having problems with taking a screenshot using Appium on Android (I'm using binaries downloaded from appium.io on Win8 machine). 

Calling the "screenshot" wire protocol command using a browser to the Appium app, returns status "0" and an empty value. As you can probably guess, calling the getScreenshot command through some language bindings (I've tried Java and Python) returns the same result. Other actions such as finding elements and clicking seems to work well. 

Here is the on screen logs from the Appium app from a call to "screenshot":

GET /wd/hub/session/a3c713ca-ce7f-4eb0-8b88-cbbf707abb7f 200 5ms - 288
debug: Appium request initiated at /wd/hub/session/a3c713ca-ce7f-4eb0-8b88-cbbf707abb7f/screenshot
info: Responding to client with success: {"status":0,"value":"","sessionId":"a3c713ca-ce7f-4eb0-8b88-cbbf707abb7f"}

So, the call returns 200 OK, but no actual data. Needless to say, the Android app being automated is shown on screen as the foreground application. 

Any help would be greately appreciated :)

[Dan Cuellar]

Due to a different bug I wasn't able to publish Appium 0.8.0 for Windows.

If you download the source from appium.io this will work. It will also work next time we cut binaries for Windows 8 which should be in a week or two I would guess.

I'll check it out. Thanks for the quick reply!

Works like a charm! (well, almost like a charm, there are some other issues, but less relevant to this thread). 

Thanks!

Hello,

Please try the below code sample for capturing screenshot in java.

        try {

        

            File classpathRoot = new File(System.getProperty("user.dir"));

            File appDir = new File(classpathRoot, "../calci-android-app/out/production/calci-android-app");

            File app = new File(appDir, "calci-android-app.apk");

            DesiredCapabilities capabilities = new DesiredCapabilities();

            capabilities.setCapability("device","Android");

            capabilities.setCapability(CapabilityType.BROWSER_NAME, "");

            capabilities.setCapability(CapabilityType.VERSION, "4.2");

            capabilities.setCapability(CapabilityType.PLATFORM, "MAC");

            capabilities.setCapability("app", app.getAbsolutePath());

            capabilities.setCapability("app-package", "com.example.calci");

            capabilities.setCapability("app-activity", ".MyActivity");

            capabilities.setJavascriptEnabled(true);

            driver = new RemoteWebDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);

            WebDriver augmentedDriver = new Augmenter().augment(driver);

            File f  = ((TakesScreenshot)augmentedDriver).getScreenshotAs(OutputType.FILE);

            FileUtils.copyFile(f, new File("screenshot.jpg"));

        } catch (Exception e) {

            e.printStackTrace();

        }

Is this working for anyone?

I tried the code for java on the iOS simulator but always get the same exception when attempting to augment the driver:

     java.lang.IllegalArgumentException: Superclass has no null constructors but no arguments were given

I'm using Junit and have a rule setup to always take a screenshot when an exception is thrown like so:

    @Rule

    public ScreenshotTestRule screenshotTestRule = new ScreenshotTestRule();

    private class ScreenshotTestRule implements MethodRule {

        public Statement apply(final Statement statement, final FrameworkMethod frameworkMethod, final Object o) {

            return new Statement() {

                @Override

                public void evaluate() throws Throwable {

                    try {

                        statement.evaluate();

                    } catch (Throwable t) {

                        captureScreenshot(frameworkMethod.getName());

                        throw t; // rethrow to allow the failure to be reported to JUnit

                    }

                }

                public void captureScreenshot(String testName) {

                    new File("target/surefire-reports/screenshot/").mkdirs(); // Insure directory is there

                    String filename = "target/surefire-reports/screenshot/" + testName + ".jpg";

                    try {

                        WebDriver augmentedDriver = new Augmenter().augment(driver);

                        File scrFile = ((TakesScreenshot)augmentedDriver).getScreenshotAs(OutputType.FILE);

                        FileUtils.copyFile(scrFile, new File(filename), true);

                    } catch (Exception e) {

                        System.out.println("Error capturing screen shot of " + testName + " test failure.");

                    }

                }

            };

        }

    }

I did notice that the driver quits and closes the simulator before the rule for the takeScreenshot can take place but thats probably a different problem. 

The test code in the appium project has the same error it looks like

https://github.com/appium/appium/blob/master/sample-code/examples/java/junit/src/test/java/com/saucelabs/appium/UICatalogTest.java

See method testScreenshot()

[Igor Gladun]

Hello.

I had problems with 

Superclass has no null constructors but no arguments were given

Solved next way, adding static and default constructor to Swipeable

(driver is static)

    public static class SwipeableWebDriver extends RemoteWebDriver implements HasTouchScreen {

        private RemoteTouchScreen touch;

        public SwipeableWebDriver() {

        }

        public SwipeableWebDriver(URL remoteAddress, Capabilities desiredCapabilities) {

            super(remoteAddress, desiredCapabilities);

            touch = new RemoteTouchScreen(getExecuteMethod());

        }

        public TouchScreen getTouch() {

            return touch;

        }

    }

public class TakeScreenshotListener extends TestListenerAdapter {

    @Override

    public void onTestFailure(ITestResult tr) {

        try {

            takeScreenshot(tr.getName());

        } catch (IOException e) {

            e.printStackTrace();

        }

    }

  public static void takeScreenshot(String testName) throws IOException {

        System.out.println("Taking screenshot");

        new File("target/surefire-reports/screenshot/").mkdirs(); 

        String filename = "target/surefire-reports/screenshot/" + testName + ".jpg";

        try {

            WebDriver augmentedDriver = new Augmenter().augment(driver);

            File scrFile = ((TakesScreenshot)augmentedDriver).getScreenshotAs(OutputType.FILE);

            FileUtils.copyFile(scrFile, new File(filename), true);

        } catch (Exception e) {

            e.printStackTrace();

            System.out.println("Error capturing screen shot of " + testName + " test failure.");

        }

        System.out.println("Took Screenshot"+testName);

    }

Thanks Igor that fixed my problem!

[Naru Segawa]

Just added
    public SwipeableWebDriver() {
    }

as Igor but without static

Hi Sakit,

Can u pls provide the code for taking screenshot of iOS in c# using appium.

Thanks  in advance.

[gobi]

Hi, i am facing trouble to take iOS device screenshot. Hereby i have given code snippet used

WebDriver driver = new RemoteWebDriver(new URL("http://127.0.0.1:27745/wd/hub"), capabilities);
            driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
            driver.get("http://www.google.com/ncr");
            driver.getTitle();
            System.out.println("Page load completed");
            WebElement element = driver.findElement(By.name("q"));
            element.sendKeys("BrowserStack");
            element.submit();
//            Get the screenshot

            WebDriver adriver =  new Augmenter().augment(driver);
            File scrFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
           
            try {
            File testScreenShot = new File("/Users/labuser/Downloads/test.jpg");
            //Copy the file to screenshot folder
            FileUtils.copyFile(scrFile, testScreenShot);

            } catch (IOException e) {
            e.printStackTrace();
            }
           
This works for me only on Simulator for real device it is not working. Do I need to setup any additional device settings for screen capture?
It keeps waiting at line
           File scrFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
  Receiving message in console, it shows for simulator also for sometimes.

Screenshot on iOS real devices only works when automating native apps--when automating Safari it won't work unfortunately.
