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

location manager android example

Question

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.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />

Answer 1

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".

Answer 2

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);
}

Answer 3

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.
