在这里发布与错误相关的代码和日志，问题是尝试使用 map api v2 显示位置，同时将数据发送到 url 得到这个异常，所以我认为发送请求有问题，但我得到了这样的 JSON 数据对我有帮助。

                    String placesSearchStr = "https://maps.googleapis.com/maps/api/place/nearbysearch/json?"
                            + "location="

                            + "&key=xxxxxxxx";
                    // execute query
                    new GetPlaces().execute(placesSearchStr);
        // Move the camera instantly to User location with a zoom of 12.
        googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(
                USER_LOCATION, 12));

        // Zoom in, animating the camera.
        googleMap.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);

索引 128 处查询中的非法字符：...

这意味着您的字符串中有非法字符。在您的情况下，它是一个管道（|）。您需要将字符编码为%7C. 如果您访问您发布的链接，您也可以看到它在那里的显示方式。

您可以手动执行此操作，也可以使用URLEncoder：

+ "&types=food%7Cbar%7Cclub"

或者

+ "&types=" + URLEncoder.encode("food|bar|club", "utf-8")
