Unable to scroll/swipe
See original GitHub issueI started to use Appium: 1.9.0 with appium-espresso-driver for the testing with webdriver. However, I cannot get scrolling/swiping working.
I tried below:
browser.touchDown(10, 900);
browser.touchMove(10, 10);
browser.touchUp(10,10);
It doesn’t give any error, but it doesn’t do anything on the page (the same happens if I use “browser.touchPerform” or “browser.touchAction”).
browser.performTouchAction([{ action: 'press', options: { x: 1945, y: 1255 } }]); browser.performTouchAction([{ action: 'moveTo', options: { x: 66, y: 470 } }]); browser.performTouchAction([{ action: 'release', options: {} }]);
Gives the following error:
An unknown server-side error occurred while processing the command. Original error: com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 2 path $ at com.google.gson.internal.bind.ReflectiveTypeAdapterFactory$Adapter.read(ReflectiveTypeAdapterFactory.java:224) at com.google.gson.Gson.fromJson(Gson.java:888) at com.google.gson.Gson.fromJson(Gson.java:853) at com.google.gson.Gson.fromJson(Gson.java:802) at com.google.gson.Gson.fromJson(Gson.java:774) at io.appium.espressoserver.lib.http.Router.route(Router.java:240) at io.appium.espressoserver.lib.http.Server.serve(Server.java:62) at fi.iki.elonen.NanoHTTPD.serve(NanoHTTPD.java:2244) at fi.iki.elonen.NanoHTTPD$HTTPSession.execute(NanoHTTPD.java:945) at fi.iki.elonen.NanoHTTPD$ClientHandler.run(NanoHTTPD.java:192) at java.lang.Thread.run(Thread.java:764) Caused by: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 2 path $ at com.google.gson.stream.JsonReader.beginObject(JsonReader.java:385) at com.google.gson.internal.bind.ReflectiveTypeAdapterFactory$Adapter.read(ReflectiveTypeAdapterFactory.java:213) … 10 more
Using browser.scroll(element_selector, 50, 900); gives me the following error:
An unknown server-side error occurred while processing the command. Original error: java.lang.NullPointerException: Attempt to invoke virtual method ‘long java.lang.Long.longValue()’ on a null object reference at io.appium.espressoserver.lib.handlers.PointerEventHandler.handleTouchScroll(PointerEventHandler.java:217) at io.appium.espressoserver.lib.handlers.PointerEventHandler.handle(PointerEventHandler.java:92) at io.appium.espressoserver.lib.handlers.PointerEventHandler.handle(PointerEventHandler.java:35) at io.appium.espressoserver.lib.http.Router.route(Router.java:251) at io.appium.espressoserver.lib.http.Server.serve(Server.java:62) at fi.iki.elonen.NanoHTTPD.serve(NanoHTTPD.java:2244) at fi.iki.elonen.NanoHTTPD$HTTPSession.execute(NanoHTTPD.java:945) at fi.iki.elonen.NanoHTTPD$ClientHandler.run(NanoHTTPD.java:192) at java.lang.Thread.run(Thread.java:764)
I tried few more methods to scroll vertically or swipe horizontally but pretty much all of them give me one of the above results. I would like to use this driver for our testing as it gives us an easy way to access elements. However, I need to have the scrolling.swiping functionality and I cannot get it working. Is there a way to do it with the current version of the driver?

Please find below the appium logs for the following commands. If you need some more logs for any particular commands please let me know:
browser.performTouchAction([{ action: 'press', options: { x: 1945, y: 1255 } }]);browser.scroll(element_selector, 50, 900);So, I’m pretty sure the issue with this:
Is that they shouldn’t be arrays, but individual objects.
As for the first one:
This should be fixed with the latest version (try installing
npm uninstall -g appium && npm install -g appium@beta). It was usingmousepointer by default before, now it usestouch.
