在代码：

locationManager.requestLocationUpdates(provider,60000,50,getListener()); 中报以下的错误：

Call requires permission which may be rejected by user: code should explicitly check to see if permission is available (with `checkPermission`) or explicitly handle a potential `SecurityException`

在AndroidManifest.xml中加入了以下的权限还是有错：

百度了下，大意是：

调用需要的权限可能被用户拒绝:代码应该显式地检查权限是否可用(用checkPermission)或显式地处理一个潜在的“SecurityException”

这是在使用 Android marshmallow(API 23)时出现的

参考以下代码解决：

private static final int MINIMUM_DISTANCE = 50; // 50m

/* GPS */

private LocationManager mLocationManager;

private LocationListener mLocationListener;

@Override

protected void onCreate(Bundle savedInstanceState) {

...

mLocationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

Criteria criteria = new Criteria();

mProviderName = mLocationManager.getBestProvider(criteria, true);

if (mProviderName == null || mProviderName.equals("")) {

startActivity(new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS));

mLocationManager.requestLocationUpdates(mProviderName, MINIMUM_TIME, MINIMUM_DISTANCE, this);

Location location = mLocationManager.getLastKnownLocation(mProviderName);

break;

case "network":

break;

case "gps":

break;

}

// One or both permissions are denied.

} else {

// The ACCESS_COARSE_LOCATION is denied, then I request it and manage the result in

// onRequestPermissionsResult() using the constant MY_PERMISSION_ACCESS_FINE_LOCATION

ActivityCompat.requestPermissions(this,

}

}
