Android:在Nexus 5上grpc失败了

Question

我正在使用地理编码器.在所有设备上,代码工作正常,但在Nexus 5手机上,日志中有例外.

我的代码:

override fun fromAddress(address: Address): Observable<Geolocation> {
    val location = geocoder.getFromLocationName("${address.street} ${address.number}, ${address.postcode}, ${address.city}", LOCATIONS_MAX_RESULTS).first()
    return Observable.just(Geolocation(latitude = location.latitude, longitude = location.longitude))
}

我的错误:

我随处可读解决方案重新安装Android工作室或更新Android工作室,但这对我不起作用.

当我从纬度和经度获取地址时，我遇到了同样的问题。我正在使用模拟器和另一个卡车屏幕设备。在这两种设备上都会出现同样的问题。GRPC 失败。但是当我在我的手机和另一台三星设备上运行此代码时，它运行得很好。我必须在卡车屏幕设备上运行它。所以我找到了一个解决方案，使用 Google Maps Location API 从纬度和经度获取位置。

String url = "https://maps.googleapis.com/maps/api/geocode/json?latlng="+log.getLattitude()+","+log.getLongitude()+"&key="+context.getResources().getString(R.string.geocodeAPiKey);

或者简单地

String url = "https://maps.googleapis.com/maps/api/geocode/json?latlng=33.25845,75.256489&key=API_KEY;

您可以像反向地理编码一样搜索它

通过此链接您可以获得用于地理编码的API 密钥

https://developers.google.com/maps/documentation/geocoding/get-api-key

在结果中你将得到一个 JSONObject。获取 JSONArray 中的第一个元素，并从中获取地址，如下所示

    JSONObject info = new JSONObject(result);
    JSONObject locationInfo = info.getJSONArray("results").getJSONObject(0);
    String locationDescription = locationInfo.getString("formatted_address");

这是反向地理编码。如果您想做简单的地理编码。几乎是这样的。我有反向地理编码代码，所以我与您分享了它。
