LocationManager's getBestProvider returning null

Question

I have a bunch of people reporting an error that I cannot reproduce. When trying to open a MapView it\'s reporting that the getBestProvider is retu

Answer 1

In your call to getBestProvider() you've asked for enabled providers only (that's the second parameter in the method call which you have set to true). If the user has disabled all providers, you will get null.

In any case, you need to be able to deal with the situation where there are no available providers, so you'll need to check for null and tell the user that he has not enabled any location.

Answer 2

androidManifest.xml

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

MapsActivity.java

 @Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    if (permissions.length == 1 &&
            permissions[0] == android.Manifest.permission.ACCESS_FINE_LOCATION &&
            grantResults[0] == PackageManager.PERMISSION_GRANTED) {
        if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling
            //    ActivityCompat#requestPermissions
            // here to request the missing permissions, and then overriding
            //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
            //                                          int[] grantResults)
            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return;
        }
        mMap.setMyLocationEnabled(true);
    } else {
        // Permission was denied. Display an error message.
    }
}

MapsActivity.java/onCreate()

if (ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION)
            == PackageManager.PERMISSION_GRANTED) {
        mMap.setMyLocationEnabled(true);
    } else {
        ActivityCompat.requestPermissions(this,new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION}, 1);
    }

this work for me;
