我知道有时google后端服务可能无法使用。
因此，解决方案可能是循环，直到我获得数据。
private class getLocationDetails extends AsyncTask<String, Void, String> {
@Override
protected String doInBackground(String... params) {
Log.d("looping", "" + count + "");
count++;
double lat = Double.parseDouble(params[0]);
double lng = Double.parseDouble(params[1]);
List<Address> addresses = null;
try {
Geocoder gCoder = new Geocoder(ImageAndLocationActivity.this,
Locale.getDefault());
addresses = gCoder.getFromLocation(lat, lng, 1);
Address addr = addresses.get(0);
user_country = addr.getCountryName();
user_city = addr.getLocality();
user_district = addr.getSubAdminArea();
if (user_city == null) {
user_city = user_district;
}
} catch (Exception e) {
Log.e("Exception in getLocationDetails - ", e.getMessage());
return null;
}
return "";
}
@Override
protected void onPostExecute(String result) {
if (result != null) {
Log.d("user_city = ", "" + user_city);
} else {
new getLocationDetails().execute(CurrentLat + "", CurrentLng
+ "");
}
}
@Override
protected void onPreExecute() {
}
@Override
protected void onProgressUpdate(Void... values) {
}
}
但我根本无法获得该位置：
logcat的：

02-27 16:29:49.568: E/Exception in getLocationDetails -(10966): Service not Available

Geocoder无效的实际原因是因为NetworkLocator在行动中被杀死了。可能是由于内存较少或者您使用任务管理器来杀死所有服务？
我不确定，但这是猜测。我以前见过这个。去年我编写了一个重新连接机制来加载NetworkLocator.apk并绑定到GeocoderService。我认为这个变化还没有合并到JellyBean中，所以这个问题仍然存在。
只能通过重启来解决。 （NetworkLocationService在启动时加载

我遇到了相同的地理编码器错误但未应用上述错误。它不会运行我的某个Android设备。然后我记得我已经加入了一些正在运行的服务。 解决方案是将电池取出几秒钟并重新安装。 它可以在不改变代码的情况下工作：））
答案 9 :(得分：0)
有些设备没有Geocoder支持，所以您需要创建自己的地理编码器。
基本上你需要创建一个异步任务来请求google获取地址并处理json响应。
使用aquery，我做这样的事情：
public void asyncJson(String address){
address = address.replace(" ", "+");
String url = "http://maps.googleapis.com/maps/api/geocode/json?address="+ address +"&sensor=true";
aq.ajax(url, JSONObject.class, new AjaxCallback<JSONObject>() {
@Override
public void callback(String url, JSONObject json, AjaxStatus status) {
if(json != null){
//here you work with the response json
JSONArray results = json.getJSONArray("results");
Toast.makeText(context, results.getJSONObject(1).getString("formatted_address"));
}else{
//ajax error, show error code
Toast.makeText(aq.getContext(), "Error:" + status.getCode(), Toast.LENGTH_LONG).show();
}
}
});

我也遇到过这个错误。最近我将设备更新到Marshmallow时发生了这种情况。
如果我重新启动，它会工作一次，但之后会失败，之后根本不会工作。
我像其他人一样创建了AsyncTask，只返回json响应的第一个结果中的地址。
要使用下面的代码，使用api键调用它构造，并使用Location对象作为输入来执行AsyncTask。您可以使用以下内容导入位置。 import android.location.Location;您必须通过请求更新它来获取LocationManager的当前位置。
new ReverseGeoCodeTask(GOOGLE_API_KEY).execute(location);
确保将api密钥替换为您自己的密钥，并确保在Google云端控制台中启用它。这是您管理特定项目的所有Google API的地方。
将此类复制为您需要反向地理编码地址的活动中的内部类。
