Kann FINE_LOCATION nicht erteilen Berechtigung

Question

Hallo Ich baue eine App Ich möchte auf den Standort des Mobiltelefons zugreifen. Es scheint jedoch, dass ich die Zugriffserlaubnis nicht erlauben kann, so funktioniert meine App nicht in Android M Handy, das ich gerade teste. Hier ist ein Teil meines Code:

public class LocationMainActivity extends AppCompatActivity { 

private ListView listView; 
private static final String EXTERNAL_PERMISSIONS[] = new String[]{ 
     Manifest.permission.ACCESS_FINE_LOCATION,Manifest.permission.INTERNET}; 
private static final int EXTERNAL_CODE=1; 
private boolean perm; 
private Cursor cursor; 
private DatabaseAdapt dbAdapt; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_location_main); 
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar4); 
    setSupportActionBar(toolbar); 
    ActionBar actionBar = getSupportActionBar(); 
    actionBar.setDisplayHomeAsUpEnabled(true); 
    listView = (ListView)findViewById(R.id.locationContainer); 

    dbAdapt = new DatabaseAdapt(this); 
    dbAdapt.open(); 
    cursor =dbAdapt.loadLocationTitles(); 
    String [] from = new String[]{DatabaseAdapt.LOCATION_TITLE}; 
    int [] to = new int[] {android.R.id.text1}; 
    CursorAdapter cursorAdapter = new SimpleCursorAdapter(this,android.R.layout.simple_list_item_1,cursor, 
      from,to,0); 
    listView.setAdapter(cursorAdapter); 
} 

public void onDestroy(){ 
    super.onDestroy(); 
    cursor.close(); 
    dbAdapt.close(); 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    getMenuInflater().inflate(R.menu.menu_main,menu); 
    return super.onCreateOptionsMenu(menu); 
} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    int id = item.getItemId(); 
    if(id==R.id.add_button);{ 
     askForPerm(); 
     if(perm){ 
      Intent intent = new Intent(LocationMainActivity.this,LocationSecondActivity.class); 
      startActivity(intent); 
     } 
     else { 
      askForPerm(); 
     } 
    } 
    return super.onOptionsItemSelected(item); 
} 

private void askForPerm() { 

    // if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { 
    int w = ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION); 
    int r = ContextCompat.checkSelfPermission(this, Manifest.permission.INTERNET); 

    if (w != PackageManager.PERMISSION_GRANTED && r != PackageManager.PERMISSION_GRANTED) { 
     ActivityCompat.requestPermissions(this, EXTERNAL_PERMISSIONS, EXTERNAL_CODE); 
    } else { 
     Toast.makeText(this, "Permissions already granted", Toast.LENGTH_SHORT).show(); 
     perm=true; 
    } 
} 

@Override 
public void onRequestPermissionsResult(int requestCode,String[] permissions, int[] grantResults) { 
    super.onRequestPermissionsResult(requestCode, permissions, grantResults); 
    switch (requestCode){ 
     case EXTERNAL_CODE: 
      if(ActivityCompat.checkSelfPermission(this,permissions[0])==PackageManager.PERMISSION_GRANTED) 
      { 
       perm=true; 
      } 
      else { 
       Toast.makeText(this,"Permissions denied",Toast.LENGTH_LONG).show(); 
       perm=false; 
      } 
      break; 
    } 
} 
} 

In dieser Aktivität mich für die Berechtigungen stellen und erst dann kann ich einen neuen Standort hinzuzufügen. Die App wechselt regelmäßig zur nächsten Aktivität, die erteilten Toast-Berechtigungen werden angezeigt, auch wenn ich die App zum ersten Mal installiere, was etwas komisch wirkt. Ich benutze den gleichen Code, um die Write External und Kameraberechtigungen in einer anderen Funktion der App anzufordern, und es funktioniert gut.

Ich habe auch den Code meiner zweiten Aktivität, wo ich die Lage

erhalten möchte

private EditText editTitleLocation, addressText, latText,longText;

      } 

      break; 
    } 

} 

Hier wird die Ortskoordinaten ist Objekt null ist und die Sicherheitsposition zeigt getriggerten, dass ich nicht die feine Standorterlaubnis Kann mir bitte jemand in die richtige Richtung zeigen? Muss ich in der zweiten Aktivität noch einmal nach Berechtigungen fragen?

Das Protokoll zeigt diese unter:

W/System.err: java.lang.SecurityException: Client must have 
    ACCESS_FINE_LOCATION permission to request PRIORITY_HIGH_ACCURACY

put folgenden Code in Ihr askForPerm() -Methode: -

LocationRequest locationRequest = LocationRequest.create(); 
    locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY); 
    locationRequest.setInterval(30 * 1000); 
    locationRequest.setFastestInterval(5 * 1000); 
    LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder() 
      .addLocationRequest(locationRequest); 
    builder.setAlwaysShow(true); //this is the key ingredient 

    PendingResult<LocationSettingsResult> result = 
      LocationServices.SettingsApi.checkLocationSettings(googleApiClient, builder.build()); 
    result.setResultCallback(new ResultCallback<LocationSettingsResult>() { 
     @Override 
     public void onResult(LocationSettingsResult result) { 
      final Status status = result.getStatus(); 
      final LocationSettingsStates state = result.getLocationSettingsStates(); 
      switch (status.getStatusCode()) { 
       case LocationSettingsStatusCodes.SUCCESS: 
        // All location settings are satisfied. The client can initialize location 
        // requests here. 
        break; 
       case LocationSettingsStatusCodes.RESOLUTION_REQUIRED: 
        // Location settings are not satisfied. But could be fixed by showing the user 
        // a dialog. 
        try { 
         // Show the dialog by calling startResolutionForResult(), 
         // and check the result in onActivityResult(). 
         status.startResolutionForResult(MainActivity.this, REQUEST_CHECK_SETTINGS); 
        } catch (IntentSender.SendIntentException e) { 
         // Ignore the error. 
        } 
        break; 
       case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE: 
        // Location settings are not satisfied. However, we have no way to fix the 
        // settings so we won't show the dialog. 
        break; 
      } 
     } 
    }); 

Try this !! Es ist in meiner Anwendung funktioniert.
