import android.content.Intent ;
import android.location.LocationManager ;
import android.os.Bundle ;
import android.provider.Settings ;
import android.support.v7.app.AlertDialog ;
import android.support.v7.app.AppCompatActivity ;
import android.view.View ;
import android.widget.Button ;
import android.widget.TextView ;
public class MainActivity extends AppCompatActivity {
   @Override
   protected void onCreate (Bundle savedInstanceState) {
      super .onCreate(savedInstanceState) ;
      setContentView(R.layout. activity_main ) ;
      Button button = findViewById(R.id. button ) ;
      button.setOnClickListener( new View.OnClickListener() {
         @Override
         public void onClick (View v) {
            locationEnabled() ;

         gps_enabled = lm.isProviderEnabled(LocationManager. GPS_PROVIDER ) ;
      } catch (Exception e) {
         e.printStackTrace() ;
      }
      try {
         network_enabled = lm.isProviderEnabled(LocationManager. NETWORK_PROVIDER ) ;
      } catch (Exception e) {
         e.printStackTrace() ;
      }
      if (!gps_enabled && !network_enabled) {
         new AlertDialog.Builder(MainActivity. this )
         .setMessage( "GPS Enable" )
         .setPositiveButton( "Settings" , new
         DialogInterface.OnClickListener() {

   }
}
Step 4 − Add the following code to androidManifest.xml
<? xml version= "1.0" encoding= "utf-8" ?>
<manifest xmlns: android = "http://schemas.android.com/apk/res/android"
   package= "app.tutorialspoint.com.sample" >
   <uses-permission android :name= "android.permission.ACCESS_FINE_LOCATION" />
   <uses-permission android :name= "android.permission.ACCESS_COARSE_LOCATION" />
   <application
      android :allowBackup= "true"
      android :icon= "@mipmap/ic_launcher"
      android :label= "@string/app_name"
      android :roundIcon= "@mipmap/ic_launcher_round"
      android :supportsRtl= "true"
      android :theme= "@style/AppTheme" >
      <activity android :name= ".MainActivity" >
         <intent-filter>
            <action android :name= "android.intent.action.MAIN" />
            <category android :name= "android.intent.category.LAUNCHER" />
