On an Android Cupcake (1.5) enabled device, how do I check and activate the GPS?
Best way seems to be the following:
final LocationManager manager = (LocationManager) getSystemService( Context.LOCATION_SERVICE );
if ( !manager.isProviderEnabled( LocationManager.GPS_PROVIDER ) ) {
buildAlertMessageNoGps();
}
private void buildAlertMessageNoGps() {
final AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Your GPS seems to be disabled, do you want to enable it?")
.setCancelable(false)
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(@SuppressWarnings("unused") final DialogInterface dialog, @SuppressWarnings("unused") final int id) {
startActivity(new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS));
}
})
.setNegativeButton("No", new DialogInterface.OnClickListener() {
public void onClick(final DialogInterface dialog, @SuppressWarnings("unused") final int id) {
dialog.cancel();
}
});
final AlertDialog alert = builder.create();
alert.show();
}
alert
for the whole activity so you can dismiss it in onDestroy to avoid a memory leak (if(alert != null) { alert.dismiss(); }
) –
Dias LocationManager.NETWORK_PROVIDER
will return true –
Rhynchocephalian dialog.cancel
when clicking the positive button, otherwise the dialog stays even if we enable the GPS. –
Catholicity In android, we can easily check whether GPS is enabled in device or not using LocationManager.
Here is a simple program to Check.
GPS Enabled or Not :- Add the below user permission line in AndroidManifest.xml to Access Location
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
Your java class file should be
public class ExampleApp extends Activity {
/** Called when the activity is first created. */
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)){
Toast.makeText(this, "GPS is Enabled in your devide", Toast.LENGTH_SHORT).show();
}else{
showGPSDisabledAlertToUser();
}
}
private void showGPSDisabledAlertToUser(){
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
alertDialogBuilder.setMessage("GPS is disabled in your device. Would you like to enable it?")
.setCancelable(false)
.setPositiveButton("Goto Settings Page To Enable GPS",
new DialogInterface.OnClickListener(){
public void onClick(DialogInterface dialog, int id){
Intent callGPSSettingIntent = new Intent(
android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(callGPSSettingIntent);
}
});
alertDialogBuilder.setNegativeButton("Cancel",
new DialogInterface.OnClickListener(){
public void onClick(DialogInterface dialog, int id){
dialog.cancel();
}
});
AlertDialog alert = alertDialogBuilder.create();
alert.show();
}
}
The output will looks like
alert
for the whole activity so you can dismiss it in onDestroy()
to avoid a memory leak (if(alert != null) { alert.dismiss(); }
) –
Alkylation yes GPS settings cannot be changed programatically any more as they are privacy settings and we have to check if they are switched on or not from the program and handle it if they are not switched on. you can notify the user that GPS is turned off and use something like this to show the settings screen to the user if you want.
Check if location providers are available
String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
if(provider != null){
Log.v(TAG, " Location providers: "+provider);
//Start searching for location and update the location text when update available
startFetchingLocation();
}else{
// Notify users and show settings if they want to enable GPS
}
If the user want to enable GPS you may show the settings screen in this way.
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivityForResult(intent, REQUEST_CODE);
And in your onActivityResult you can see if the user has enabled it or not
protected void onActivityResult(int requestCode, int resultCode, Intent data){
if(requestCode == REQUEST_CODE && resultCode == 0){
String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
if(provider != null){
Log.v(TAG, " Location providers: "+provider);
//Start searching for location and update the location text when update available.
// Do whatever you want
startFetchingLocation();
}else{
//Users did not switch on the GPS
}
}
}
Thats one way to do it and i hope it helps. Let me know if I am doing anything wrong.
startActivityForResult
with multiple intents. When the intents return to your activity, you check the RequestCode to see which intent is returning and respond accordingly. –
Hoicks provider
can be an empty string. I had to change the check to (provider != null && !provider.isEmpty())

Yerxa Here are the steps:
Step 1: Create services running in background.
Step 2: You require following permission in Manifest file too:
android.permission.ACCESS_FINE_LOCATION
Step 3: Write code:
final LocationManager manager = (LocationManager)context.getSystemService (Context.LOCATION_SERVICE );
if ( !manager.isProviderEnabled( LocationManager.GPS_PROVIDER ) )
Toast.makeText(context, "GPS is disabled!", Toast.LENGTH_LONG).show();
else
Toast.makeText(context, "GPS is enabled!", Toast.LENGTH_LONG).show();
Step 4: Or simply you can check using:
LocationManager manager = (LocationManager) getSystemService(Context.LOCATION_SERVICE );
boolean statusOfGPS = manager.isProviderEnabled(LocationManager.GPS_PROVIDER);
Step 5: Run your services continuously to monitor connection.
Yes you can check below is the code:
public boolean isGPSEnabled (Context mContext){
LocationManager locationManager = (LocationManager)
mContext.getSystemService(Context.LOCATION_SERVICE);
return locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
}
In Kotlin: How to check GPS is enable or not
val manager = getSystemService(Context.LOCATION_SERVICE) as LocationManager
if (!manager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
checkGPSEnable()
}
private fun checkGPSEnable() {
val dialogBuilder = AlertDialog.Builder(this)
dialogBuilder.setMessage("Your GPS seems to be disabled, do you want to enable it?")
.setCancelable(false)
.setPositiveButton("Yes", DialogInterface.OnClickListener { dialog, id
->
startActivity(Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS))
})
.setNegativeButton("No", DialogInterface.OnClickListener { dialog, id ->
dialog.cancel()
})
val alert = dialogBuilder.create()
alert.show()
}
This method will use the LocationManager service.

//Check GPS Status true/false
public static boolean checkGPSStatus(Context context){
LocationManager manager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE );
boolean statusOfGPS = manager.isProviderEnabled(LocationManager.GPS_PROVIDER);
return statusOfGPS;
};
Here is the snippet worked in my case
final LocationManager manager = (LocationManager) getSystemService(Context.LOCATION_SERVICE );
if ( !manager.isProviderEnabled( LocationManager.GPS_PROVIDER ) ) {
buildAlertMessageNoGps();
}
`
GPS will be used if the user has allowed it to be used in its settings.
You can't explicitly switch this on anymore, but you don't have to - it's a privacy setting really, so you don't want to tweak it. If the user is OK with apps getting precise co-ordinates it'll be on. Then the location manager API will use GPS if it can.
If your app really isn't useful without GPS, and it's off, you can open the settings app at the right screen using an intent so the user can enable it.
Kotlin Solution :
private fun locationEnabled() : Boolean {
val locationManager = getSystemService(Context.LOCATION_SERVICE) as LocationManager
return locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)
}
In your LocationListener
, implement onProviderEnabled
and onProviderDisabled
event handlers. When you call requestLocationUpdates(...)
, if GPS is disabled on the phone, onProviderDisabled
will be called; if user enables GPS, onProviderEnabled
will be called.
