Check if Google's location Service is enabled by the user, else open Settings > Location so the user enables them.
First get the
String locationProviders = Settings.Secure.getString(getContentResolver(),Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
contains "network" or "gps" or both values separated by comma.
If the string is empty => Google Location Service is closed and you have to prompt the user to open it. Wifi might or not be open.
If the string equals "network" => WiFi and Google Location Service are enabled.
If the string equals "network,gps" => WiFi and GPS and Location Service are enabled.
We need to create a Dialog and ask the user to take the action he wants. In our case we want the user when she clicks Yes to open the Settings > Location , so she can enable the Location Service.
We can achieve that with ACTION_LOCATION_SOURCE_SETTINGS.
The code is :
if (locationProviders == null || locationProviders.equals("")) {
new AlertDialog.Builder(this)
.setTitle("Enable Location Service")
.setMessage("This Application requires the use of Google Location's service. " +
"Do you wish to enable this feature")
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// show system settings
startActivity(new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS));
}
})
.setNegativeButton("No", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// do nothing
}
})
.show();
}
