Check and prompt user to enable GPS

To check if the GPS have been enabled or not, the following code can be used:

String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);

If it's empty, means the GPS have not been enabled. You can start activity with intent Settings.ACTION_SECURITY_SETTINGS, to switch to GPS setting page.




package com.exercise.AndroidEnableGPS;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.provider.Settings;
import android.widget.Toast;

public class AndroidEnableGPS extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

CheckEnableGPS();
}

private void CheckEnableGPS(){
String provider = Settings.Secure.getString(getContentResolver(),
Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
if(!provider.equals("")){
//GPS Enabled
Toast.makeText(AndroidEnableGPS.this, "GPS Enabled: " + provider,
Toast.LENGTH_LONG).show();
}else{
Intent intent = new Intent(Settings.ACTION_SECURITY_SETTINGS);
startActivity(intent);
}

}
}
