Question

I am trying to create an app. App asking every time location Access in Marsh Mallow, always when we open the app. Please suggested the best Process for solve my problem. using following code-

@Override
public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;
//for marshmallow
    final int LOCATION_PERMISSION_REQUEST_CODE = 100;
     ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION, android.Manifest.permission.ACCESS_COARSE_LOCATION},
            LOCATION_PERMISSION_REQUEST_CODE);

    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

        return;
    }
    mMap.setMyLocationEnabled(true);
    buildGoogleApiClient();
    mGoogleApiClient.connect();

}

thanks.

Please reflect your code yourself. Think about the order of requesting and checking the permission. You should check the permission before you're asking for it. This makes sure to prevent asking if the permission was already granted...

Have a look at the example provided by Google and consider adapting this example for your needs:

// Here, thisActivity is the current activity
if (ContextCompat.checkSelfPermission(thisActivity, Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED)     {

    // Should we show an explanation?
    if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity, Manifest.permission.READ_CONTACTS)) {

        // Show an expanation to the user *asynchronously* -- don't block
        // this thread waiting for the user's response! After the user
        // sees the explanation, try again to request the permission.

    } else {

        // No explanation needed, we can request the permission.

        ActivityCompat.requestPermissions(thisActivity,
            new String[]{Manifest.permission.READ_CONTACTS},
            MY_PERMISSIONS_REQUEST_READ_CONTACTS);

        // MY_PERMISSIONS_REQUEST_READ_CONTACTS is an
        // app-defined int constant. The callback method gets the
        // result of the request.
    }
}

Additionally you should overwrite the callback method onRequestPermissionsResult to handle the user's grantResults .

// Callback with the request from calling requestPermissions(...)
@Override
public void onRequestPermissionsResult(int requestCode,
                                       @NonNull String permissions[],
                                       @NonNull int[] grantResults) {
    // Make sure it's our original READ_CONTACTS request
    if (requestCode == READ_CONTACTS_PERMISSIONS_REQUEST) {
        if (grantResults.length == 1 &&
                grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            Toast.makeText(this, "Read Contacts permission granted", Toast.LENGTH_SHORT).show();
        } else {
            Toast.makeText(this, "Read Contacts permission denied", Toast.LENGTH_SHORT).show();
        }
    } else {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }
}

Edit:

This is thecode which you should change

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

if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

    return;
}

Try writting in if else, if permission is not given ask for it or else do what you want to do.

  if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            if(checkSelfPermission(Manifest.permission.Manifest.permission.ACCESS_FINE_LOCATION)
                        != PackageManager.PERMISSION_GRANTED) {
                    requestPermissions(new String[]{Manifest.permission.Manifest.permission.ACCESS_FINE_LOCATION},
                            LOCATION_PERMISSION_REQUEST_CODE);
                }
            } else {
               // do your stuff
            }

and also override onRequestPermissionsResult and apply your code afer you have granted permissions.

The following code checks if the app has permission for working with location, and requests the permission if necessary:

// Here, thisActivity is the current activity
if (ContextCompat.checkSelfPermission(thisActivity,
        Manifest.permission.ACCESS_FINE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {

    // Should we show an explanation?
    if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
    Manifest.permission.ACCESS_FINE_LOCATION)) {

        // Show an expanation to the user *asynchronously* -- don't block
        // this thread waiting for the user's response! After the user
        // sees the explanation, try again to request the permission.

    } else {

        // No explanation needed, we can request the permission.

        ActivityCompat.requestPermissions(thisActivity,
        new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
        MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION_CODE);

        // MY_PERMISSIONS_REQUEST_READ_CONTACTS is an
        // app-defined int constant. The callback method gets the
        // result of the request.
    }
}
else
{
    // Permission already granted ... This is where you can continue your further business logic...
}

And the following is the callback method:

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION_CODE: {
            // If request is cancelled, the result arrays are empty.
            if (grantResults.length > 0
        && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                // permission was granted, yay! Do the
                // Locatio-related task you need to do.

            } else {

                // permission denied, boo! Disable the
                // functionality that depends on this permission.
            }
            return;
        }

        // other 'case' lines to check for other
        // permissions this app might request
    }
}
