【问题描述】：
在service 中请求位置更新时出现此错误。已授予定位权限，LocationManager 不为空，Provider 不为空。
LocationManager: [LocationManager] requestLocationUpdates(),

我在onStartCommand()内部呼叫的位置代码：
@SuppressLint("MissingPermission")
private void createAndRequestLocationUpdates() {
try {
if (!TrackThatUtils.isLocationEnabled(getApplicationContext())) {
Log.e(TAG, "Location is disable.");
return;
}
if (locationManager == null) {
locationManager = (LocationManager) getApplicationContext().getSystemService(Context.LOCATION_SERVICE);
addProximityAlert();
}
if (locationManager == null || !locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
Log.e(TAG, "Location provider is disable.");
return;
}
// getting GPS status
boolean isGPSEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
Log.e(TAG, "Location provider is: " + isGPSEnabled);
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED &&
ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
// ActivityCompat#requestPermissions
// here to request the missing permissions, and then overriding
// public void onRequestPermissionsResult(int requestCode, String[] permissions,

// for ActivityCompat#requestPermissions for more details.
Log.e(TAG, "== Error On onConnected() Permission not granted");
//Permission not granted by user so cancel the further execution.
return;
}
Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_FINE);
criteria.setPowerRequirement(Criteria.NO_REQUIREMENT);
criteria.setAltitudeRequired(false);
criteria.setSpeedRequired(true);
//setCostAllowed(true): This flag enables LocationManager to exchange “data packet” with
// 3G/4G network base stations in order to get better location
criteria.setCostAllowed(true);
criteria.setBearingRequired(false);
//API level 9 and up
criteria.setHorizontalAccuracy(Criteria.ACCURACY_HIGH);
criteria.setVerticalAccuracy(Criteria.ACCURACY_HIGH);
String provider = locationManager.getBestProvider(criteria, true);
// locationManager.requestLocationUpdates(gpsFreqInMillis, gpsFreqInDistance, criteria, locationListener, null);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0,
0, this);
Log.i(TAG, "request for location updates..");
} catch (SecurityException | IllegalArgumentException e) {
Log.e(TAG, "Exception inside createAndRequestLocationUpdates(): " + e);
}
}

检查我的答案，它是一个完整的解决方案，使用 google api 客户端运行时权限，试试看，如果有帮助，请告诉我
-
可能你正在从任何处理程序/线程调用
requestLocationUpdates。尝试在 Activity 或 Fragment 的 onCreate() 中替换您的调用方法。 -
@Quicklearner 感谢您的快速回复。我在服务中使用此代码，并且我使用的是 LocationManager 未融合的 API
-
使用 google api 客户端是一种很好且安全的技术 :) 我会说一个很好的做法
