Perform Swipe On Screen Using Accessibilityservice

I want to perform swipe on screen using accessibility service. i tried this but this only perform a single touch. i know it is possible because when enable my service on device it

Solution 1:

I think you have multiple problems. How you're building your gesture is a little off, and the number of pixels you have to move for it to be a swipe is bigger than you think! I would calculate this based on screen size, rather than a specific number of pixels. I think of a typical swipe gesture as about half the screen, originating from one side to the other, right in the middle height wise.

I set up a silly little "onAccessibilityEvent" listener, that on my Nexus 6 bounces back and forth between home screen 1 and home screen two. You have to have two home screens set up obviously to see it in action.

@OverridepublicvoidonAccessibilityEvent(AccessibilityEvent event) {

    switch (event.getEventType()) {
        case AccessibilityEvent.TYPE_ANNOUNCEMENT:
            if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.N) {

                DisplayMetricsdisplayMetrics= getResources().getDisplayMetrics();

                intmiddleYValue= displayMetrics.heightPixels / 2;
                finalintleftSideOfScreen= displayMetrics.widthPixels / 4;
                finalintrightSizeOfScreen= leftSideOfScreen * 3;
                GestureDescription.BuildergestureBuilder=newGestureDescription.Builder();
                Pathpath=newPath();

                if (event.getText() != null && event.getText().toString().contains("1")) {
                    //Swipe left
                    path.moveTo(rightSizeOfScreen, middleYValue);
                    path.lineTo(leftSideOfScreen, middleYValue);
                } else {
                    //Swipe right
                    path.moveTo(leftSideOfScreen, middleYValue);
                    path.lineTo(rightSizeOfScreen, middleYValue);
                }

                gestureBuilder.addStroke(newGestureDescription.StrokeDescription(path, 100, 50));
                dispatchGesture(gestureBuilder.build(), newGestureResultCallback() {
                    @OverridepublicvoidonCompleted(GestureDescription gestureDescription) {
                        Log.w("Gesture Completed");
                        super.onCompleted(gestureDescription);
                    }
                }, null);
            }

        default: {
            break;
        }
    }
}

Also important is the accessibility configuration info, check out my config xml file

<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"android:description="@string/accessibility_service_description"android:accessibilityEventTypes="typeAllMask"android:accessibilityFlags="flagReportViewIds"android:canRetrieveWindowContent="true"android:canRequestTouchExplorationMode="true"android:accessibilityFeedbackType="feedbackSpoken"android:notificationTimeout="100"android:settingsActivity="com.moba11y.basicaccessibilityservice.SettingsActivity"android:canPerformGestures="true"
/>

EDIT:

To support swiping up or down you just need to change your path arguments.

finalint height = displayMetrics.heightPixels;
finalint top = height * .25;
finalint mid = height * .5;
finalint bottom = height * .75;
finalint midX = displayMetrics.widthPixels / 2;

if(swipeUp) {
    path.moveTo(midX, bottom);
    path.lineTo(midX, top);
} else {
    path.moveTo(midX, top);
    path.lineTo(midX, bottom);
}

Solution 2:

Make sure you configured your service to perform gestures:

android:canPerformGestures="true"

Setup your path correctly:

p.moveTo(position.x, position.y);
p.lineTo(position.x + 300, position.y); 

It only works on android 24 and above.
