java - manager - Android "gps requiere el error ACCESS_FINE_LOCATION", aunque mi archivo de manifiesto contenga esto



location manager android example (3)

Cada vez que ejecuto la aplicación, se lanza mi SecurityException y el error del depurador dice así:

java.lang.SecurityException: el proveedor de ubicación "gps" requiere el permiso ACCESS_COARSE_LOCATION o ACCESS_FINE_LOCATION.

Esto parece un simple error, sin embargo, mi archivo de manifiesto es completamente correcto. Aquí está, y aquí está también mi código de MapActivity:

<?xml version="1.0" encoding="utf-8"?>

<uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" /> <uses-permission android:name="com.dev.cromer.jason.coverme.permission.MAPS_RECEIVE" /> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name=".MainActivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" /> <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value= "@string/google_maps_key" /> <activity android:name=".MapActivity" android:label="@string/title_activity_map" > </activity> </application>

Mi actividad:

package com.dev.cromer.jason.coverme; import android.location.Criteria; import android.location.Location; import android.location.LocationListener; import android.location.LocationManager; import android.support.v4.app.FragmentActivity; import android.os.Bundle; import android.util.Log; import com.google.android.gms.common.ConnectionResult; import com.google.android.gms.common.api.GoogleApiClient; import com.google.android.gms.location.LocationServices; import com.google.android.gms.maps.CameraUpdateFactory; import com.google.android.gms.maps.GoogleMap; import com.google.android.gms.maps.SupportMapFragment; import com.google.android.gms.maps.model.LatLng; import com.google.android.gms.maps.model.MarkerOptions; public class MapActivity extends FragmentActivity implements LocationListener { private GoogleMap mMap; // Might be null if Google Play services APK is not available. @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_map); setUpMapIfNeeded(); } @Override protected void onResume() { super.onResume(); setUpMapIfNeeded(); } private void setUpMapIfNeeded() { // Do a null check to confirm that we have not already instantiated the map. if (mMap == null) { // Try to obtain the map from the SupportMapFragment. mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)) .getMap(); // Check if we were successful in obtaining the map. if (mMap != null) { //mMap.setMyLocationEnabled(true); //mMap.setOnMyLocationChangeListener(this); setUpMap(); } } } private void setUpMap() { mMap.addMarker(new MarkerOptions().position(new LatLng(0, 0)).title("Marker")); mMap.setMyLocationEnabled(true); LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE); try { Location myLocation = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER); if (myLocation != null) { Log.d("TAG", "Not null"); } else { Log.d("TAG", "NULL"); locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this); } } catch (SecurityException se) { Log.d("TAG", "SE CAUGHT"); se.printStackTrace(); } } @Override public void onLocationChanged(Location location) { Log.d("CHANGED", "LOCATION UPDATED"); } @Override public void onStatusChanged(String provider, int status, Bundle extras) { } @Override public void onProviderEnabled(String provider) { } @Override public void onProviderDisabled(String provider) { } }


CAUSA: "A partir de Android 6.0 (API nivel 23), los usuarios otorgan permisos a las aplicaciones mientras la aplicación se está ejecutando, no cuando la instalan". En este caso, "ACCESS_FINE_LOCATION" es un "permiso peligroso y por esa razón, obtiene este ''java.lang.SecurityException: el proveedor de ubicación" gps "requiere el permiso ACCESS_FINE_LOCATION". error ( https://developer.android.com/training/permissions/requesting.html ).

SOLUCIÓN: Implementar el código provisto en https://developer.android.com/training/permissions/requesting.html bajo los encabezados "Solicitar los permisos que necesita" y "Manejar los permisos de respuesta de solicitud de permisos".


Mi solución simple es esta

if (ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED && ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED) { googleMap.setMyLocationEnabled(true); googleMap.getUiSettings().setMyLocationButtonEnabled(true); } else { Toast.makeText(this, R.string.error_permission_map, Toast.LENGTH_LONG).show(); }

o puede abrir el diálogo de permisos en otra cosa como esta

} else { ActivityCompat.requestPermissions(this, new String[] { Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION }, TAG_CODE_PERMISSION_LOCATION); }


ACCESS_COARSE_LOCATION , ACCESS_FINE_LOCATION y WRITE_EXTERNAL_STORAGE son parte del sistema de permisos de tiempo de ejecución de Android 6.0 . Además de tenerlos en el manifiesto como lo hace, también debe solicitarlos al usuario en tiempo de ejecución (usando requestPermissions() ) y ver si los tiene (usando checkSelfPermission() ).

Una solución a corto plazo es dejar su targetSdkVersion por debajo de 23.

Pero, eventualmente, querrás actualizar tu aplicación para usar el sistema de permisos de tiempo de ejecución.

Por ejemplo, esta actividad funciona con cinco permisos. Cuatro son permisos de tiempo de ejecución, aunque actualmente solo maneja tres (lo escribí antes de que se añadiera WRITE_EXTERNAL_STORAGE a la lista de permisos de tiempo de ejecución).

(de este proyecto de muestra )

Para la función requestPermissions (), ¿los parámetros deberían ser "ACCESS_COARSE_LOCATION"? ¿O debería incluir el nombre completo "android.permission.ACCESS_COARSE_LOCATION"?

Usaría las constantes definidas en el Manifest.permission , como se muestra arriba.

Además, ¿cuál es el código de solicitud?

Eso se le devolverá como el primer parámetro a onRequestPermissionsResult() , para que pueda distinguir una llamada requestPermissions() de otra.
