java - NullPointerException：尝试从空对象引用上的字段“int com.google.android.gms.location.LocationRequest.a”读取
问题描述
我不明白为什么单击 startService 是一个前台服务时会出现此错误，并通知将应用程序更新位置保持在后台
atcom.raismedia.taxiclient.TrackingService.requestLocationUpdates(TrackingService.java:367) at com.raismedia.taxiclient.TrackingService.onConnected(TrackingService.java:349)
在这些行中
public void startLocationUpdates() {
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,
// int[] grantResults)
// to handle the case where the user grants the permission. See the documentation
// for ActivityCompat#requestPermissions for more details.
return;
}
-------------->367 LocationServices.FusedLocationApi.requestLocationUpdates(googleApiClient, locationRequest, this);
}
@Override
public void onConnected(@Nullable Bundle bundle) {
// Permissions ok, we get last location
