android - 在 Android 中使用 Google 地图访问用户的当前位置时应用程序崩溃
问题描述
我正在尝试到达用户的当前位置。在运行应用程序时崩溃。该地图正在工作，它指向默认的经纬度，即悉尼，但在尝试访问当前位置时应用程序崩溃。我创建了 enableUserLocation 方法来检查权限。
class MapsActivity : AppCompatActivity(), OnMapReadyCallback {
private lateinit var mMap: GoogleMap
private lateinit var geofencingClient: GeofencingClient
private var FINE_LOCATION_ACCESS_REQUEST_CODE = 10001
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_maps)
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
val mapFragment = supportFragmentManager
.findFragmentById(R.id.map) as SupportMapFragment
mapFragment.getMapAsync(this)
geofencingClient = LocationServices.getGeofencingClient(this)
}
/**
* Manipulates the map once available.
* This callback is triggered when the map is ready to be used.
* This is where we can add markers or lines, add listeners or move the camera. In this case,
* we just add a marker near Sydney, Australia.
* If Google Play services is not installed on the device, the user will be prompted to install
* it inside the SupportMapFragment. This method will only be triggered once the user has
* installed Google Play services and returned to the app.
*/
override fun onMapReady(googleMap: GoogleMap) {
mMap = googleMap
// Add a marker in Sydney and move the camera
val sydney = LatLng(-34.0, 151.0)
mMap.addMarker(MarkerOptions().position(sydney).title("Marker in Sydney"))
mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney))
enableUserLocation()
}
private fun enableUserLocation() {
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
== PackageManager.PERMISSION_GRANTED
) {
mMap.isMyLocationEnabled = true
} else {
//Ask for permission
if (ActivityCompat.shouldShowRequestPermissionRationale(
this,
Manifest.permission.ACCESS_FINE_LOCATION
)
) {
//we need to show a user dialog that why the permission is needed and then ask for the permission
ActivityCompat.requestPermissions(
this,
arrayOf(Manifest.permission.ACCESS_FINE_LOCATION),
FINE_LOCATION_ACCESS_REQUEST_CODE
)
} else {
ActivityCompat.requestPermissions(
this,
arrayOf(Manifest.permission.ACCESS_FINE_LOCATION),
FINE_LOCATION_ACCESS_REQUEST_CODE
)
}
}
}
override fun onRequestPermissionsResult(
requestCode: Int,
permissions: Array<out String>,
grantResults: IntArray
) {
if (requestCode == FINE_LOCATION_ACCESS_REQUEST_CODE) {
if (grantResults.size > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
//We have the permission
mMap.isMyLocationEnabled = true
} else {
//we do not have the permission
}
}
}
}
这是 logcat 错误，它说它是运行时异常。
