Appium 点击Android屏幕

用driver.tap(1, 10, 10, 800); 点击屏幕，经常提示：An unknown server-side error occurred while processing the command

测试中断，经查找资料，如下方法很好用：

@SuppressWarnings("unchecked")

public void touchScreen(){
@SuppressWarnings("rawtypes")
Map tap = new HashMap();
tap.put("tapCount", new Double(2));
tap.put("touchCount", new Double(1));
tap.put("duration", new Double(0.5));
tap.put("x", new Double(300));
tap.put("y", new Double(300));
driver.executeScript("mobile: tap", tap);
}
