Question

I have my login screen in app now. Each time the app is launched in screen the mobile number is pre filled with the older text.

I just want to know I have tried:

I had trouble with this too. A main issue I found was that in order to delete the area by pressing the delete key was that it needed to tap at the end of the line. This works for me:

public void clearTextField(WebElement element) {
    double x = element.getLocation().getX() + element.getSize().width - 5;
    double y = element.getLocation().getY() + ((double) element.getSize().height / 3);
    preciseTap(x, y, 0.1, 1);
    while (!element.getText().isEmpty()) {
        pressDeleteKey();
    }
}

public void preciseTap(double x, double y, double duration, int touchCount) {
    JavascriptExecutor js = (JavascriptExecutor) driver;
    HashMap tapObject = new HashMap();
    tapObject.put("x", x);
    tapObject.put("y", y);
    tapObject.put("touchCount", (double)touchCount);
    tapObject.put("duration", duration);
    js.executeScript("mobile: tap", tapObject);
}

public void pressDeleteKey() {
    HashMap swipeObject = new HashMap();
    swipeObject.put("keycode", 67);
    ((JavascriptExecutor) driver).executeScript("mobile: keyevent", swipeObject);
}

It is a lot slower than just clearing it all out but I have not figured out how to do this yet. Would be ideal to double tap or tap and hold until everything is selected.
