How to programmatically enable GPS in Android Cupc

Question

I'm currently writing an app in Android that works with the GPS. At the moment I'm able to work out whether the GPS is enabled. My problem is that I want to enable the GPS on app startup if it is disabled. How can I do this programmaticaly?

Answer 1

You can't, starting with Android 1.5. The most you can do is pop open the activity to allow the user to toggle it on/off. Use the action held in android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS to craft an Intent to open this activity.

Answer 2

First check whether the location service is already on or not ??

Checking location service is enabled or not

public boolean isLocationServiceEnabled(){
    LocationManager locationManager = null;
    boolean gps_enabled= false,network_enabled = false;

    if(locationManager ==null)
        locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    try{
        gps_enabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
    }catch(Exception ex){
        //do nothing...
    }

    try{
        network_enabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
    }catch(Exception ex){
        //do nothing...
    }

    return gps_enabled || network_enabled;

}

Then finally to open if location service in turned off previously

  if (isLocationServiceEnabled())) {
          //DO what you need...
     } else {
          AlertDialog.Builder builder = new AlertDialog.Builder(this);
          builder.setMessage("Seems Like location service is off,   Enable this to show map")
      .setPositiveButton("YES", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialogInterface, int i) {
                             Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
                                    startActivity(intent);
                                }
                            }).setNegativeButton("NO THANKS", null).create().show();
                }

You might use the following:

try {
  Settings.Secure.setLocationProviderEnabled(getContentResolver(), LocationManager.GPS_PROVIDER, true);
} catch (Exception e) {
  logger.log(Log.ERROR, e, e.getMessage());
}

but it will only work if you have system signature protection level. So you need to cook your own Image to actually use it :/

Answer 4

if your question is at the user level of android these properties are located in: "Settings -> Location -> Use wireless networks" -> "Settings -> Location -> Use GPS satellites".

But at the developer can use the class "android.provider.Settings.Secure" with the appropriate permissions.

Answer 5

This method code can be help for you

private void turnGPSOnOff(){
  String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
  if(!provider.contains("gps")){
    final Intent poke = new Intent();
    poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider");
    poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
    poke.setData(Uri.parse("3")); 
    sendBroadcast(poke);
    //Toast.makeText(this, "Your GPS is Enabled",Toast.LENGTH_SHORT).show();
  }
}

Answer 6

You should use the Location Settings Dialog in Play Services that prompts the user to enable location services (if necessary) with just one click.
