Design an android based application to demostrate GPS services using Google Maps
Code:-
MainActivity.java:-
package
com.example.mapservices;
public
class MainActivity extends AppCompatActivity {
EditText etSource,etDestination;
Button btTrack;
@Override
protected void onCreate(Bundle
savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
etSource =
findViewById(R.id.et_source);
etDestination =
findViewById(R.id.et_destination);
btTrack = findViewById(R.id.bt_track);
btTrack.setOnClickListener(new
View.OnClickListener() {
@Override
public void onClick(View view) {
String sSource =
etSource.getText().toString().trim();
String sDestination =
etDestination.getText().toString().trim();
if
(sSource.equals("") && sDestination.equals("")){
Toast.makeText(getApplicationContext(),"Enter both location",
Toast.LENGTH_SHORT).show();
}else{
DisplayTrack(sSource,sDestination);
}
}
private void DisplayTrack(String
sSource, String sDestination) {
try {
Uri uri = Uri.parse("https://www.google.co.in/maps/dir/"
+ sSource + "/" + sDestination);
Intent intent = new
Intent(Intent.ACTION_VIEW,uri);
intent.setPackage("com.google.android.apps.maps");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}catch(ActivityNotFoundException e){
Uri uri =
Uri.parse("https://play.google.com/store/apps/details?id=com.google.android.apps.maps");
Intent intent = new
Intent(Intent.ACTION_VIEW,uri);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}
}
});
}}
