keine Berechtigungen erlaubt Auto android Studio

Question

Ich versuche Wetterinformationen mit GPS-Standort zu bekommen, aber das Problem ist Wert für meine Position 0,0 ("Breite, Länge"). Wenn ich auf Einstellung für mein Telefon gehe -> "Erlaubnis" fand keine Erlaubnis erlaubt, und ich muss die Erlaubnis manuell aktivieren. Dann funktioniert die App gut.

ich auf Version 4.4.2 getestet und es funktionierte gut und die Erlaubnis Auto erlaubt, aber auf Version 7.0 Ich habe die Erlaubnis zur Aktivierung manuell von der Einstellung Ideen ?

Answer 1

Versuchen Sie diesen Code ActivityCompat.requestPermissions

Es ist ein Tutorial oder höher verwenden

private int PERMISSIONS_REQUEST_LOCATION = 100; 

protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main_activity); 

     if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) { 
       if (ContextCompat.checkSelfPermission(MainFragmentActivity.this, ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) { 
        if (ActivityCompat.shouldShowRequestPermissionRationale(MainFragmentActivity.this,ACCESS_FINE_LOCATION)) { 

        } else { 
      ActivityCompat.requestPermissions(MainFragmentActivity.this, new String[]{ACCESS_FINE_LOCATION}, PERMISSIONS_REQUEST_LOCATION); 
        } 
       } 
     } 
} 

Answer 2

Sie müssen die Laufzeitberechtigung anfordern.

Sie tun das auf tun dies in Android Version 6.0 für Runtime Permission here
