I am making an app with Android Studio where the google maps shows the user's location, and i want to add an acceleration detector so when the acceleration of the user is very large, an alert dialog pops up.
The map with the user's location is working, but when I try to add the acceleration sensor, the app crashes (no error warning). The code is the following:
public abstract class Mapa extends FragmentActivity implements OnMapReadyCallback, SensorEventListener {

I don't understand where the error is, could you help me please?
I finally figured it on my own, so I'll post the answer in case anyone else may need it.
Apparently it does not work when you put the Google maps and the accelerometer in the same activity, so I had to separate them. Ir order to do so, I used a Service for detecting the acceleration.
I managed to get my Service going by looking at this:
Android sensors not working in a service
Once this is done, I send my accelerometer info to my maps activity with a LocalBroadcastManager:
How to use LocalBroadcastManager?
By following the instructions given in these 2 questions I managed to make it work.

I created a MapsActivity and corresponding activity_maps.xml.My activity_main.xml there will be a button which when tapped should show the current location pointed by a marker.
Code works fine when making the MapsActivity as Launcher Activity in AndroidManifest.xml but want my MainActivity to be the Launcher Activity.
how I can make my MainActivity as Launcher Activity.

i want to access current location in fragments , but i am using API 28 and android version 3.2.1. i try everything from internet follow tutorials but i cant access my current location , there is no error in my code but i don't know why i cant access it. when i run my program i just see google default map, no marker etc.
i want to access my location through network provider as well as gps provider if network provider is not available.
i also add permissions in manifest
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
for a permission access i am using library from github and for lacation and map
implementation 'pub.devrel:easypermissions:2.0.0'
implementation 'com.google.android.gms:play-services-maps:16.0.0'
implementation 'com.google.android.gms:play-services-location:16.0.0'
please check my code and guide me how i can access current location my code is in below in my code there is also step counter code but ignore that one.

but remember i am using ApI 28
I want get the current location of user on map
when I run the app ,app is successfully launched it takes the permission from user to take location of user through GPS but marker is not showing on map.
when i run the this app on emulator it shows some where else location and when i run this app on mobile it does not show location(marker)
her is the code .

when i run the this app on emulator it shows some where else location
It's not showing your current location because when using the emulator, it's location is set in the settings, it doesn't determine your actual location, so basically it's set manually.
when i run this app on mobile it does not show location(marker)
Regarding that, you can try calling addMarker in onMapReady directly first. And moving your onLocationChanged callback outside of the onMapReady.
I want a marker to show my current location. All permissions needed are added. When I comment out mMap.addMarker and mMap.moveCamera the app is working and Googlemaps is shown. If I let one of those two in my code the app crashes before the map even opens.
I've tried with removing the marker if it isn't null but this doesn't solve the problem.
Do you guys have any idea how I can get the app working?

Okay, I already solved the problem. So I post the solution here.
I have implemented on the MapsActivity the LocationListener interface and for some reason it doesn't work this way. I can retrieve the geocoordinates but as soon as I want to move the camera or add a marker it the app crashes as it gets opened.
I don't know why, but instead of:
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 3000, 5, this)
I undo the implementation of the LocationListener and just create a new one at the position of ,,this":
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 3000, 5, new LocationListener() {
#Override
public void onLocationChanged(Location location) {
posLat = location.getLatitude();
posLng = location.getLongitude();
position = new LatLng(posLat, posLng);
if (mPosition != null) {
mPosition.remove();
}
mPosition = mMap.addMarker(new MarkerOptions().position(position).title("Your position").
icon(BitmapDescriptorFactory.fromResource(R.drawable.location)));
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(position, 11));
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
#Override
public void onProviderEnabled(String provider) {
}
#Override
public void onProviderDisabled(String provider) {
}
}
);
and this way it works without problem.
I am using this code in android 6.0 to get the position:
public class MainActivity extends AppCompatActivity implements LocationListener{
protected LocationManager locationManager;
protected LocationListener locationListener;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
if (checkPermission())
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
}
#Override
public void onLocationChanged(Location location) {
lati = location.getLatitude();
longi = location.getLongitude();
}
#Override
public void onProviderDisabled(String provider) {
Log.d("Latitude", "disable");
}
#Override
public void onProviderEnabled(String provider) {
Log.d("Latitude", "enable");
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
Log.d("Latitude", "status");
}
private boolean checkPermission(){
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
// ActivityCompat#requestPermissions
// here to request the missing permissions, and then overriding
// public void onRequestPermissionsResult(int requestCode, String[] permissions,
// int[] grantResults)
// to handle the case where the user grants the permission. See the documentation
// for ActivityCompat#requestPermissions for more details.
return false;
}
return true;
}
}
I set the permissions in the programs properties to true.
It used to work but now it never finds satellites or the position in general.
Google maps immediately finds satellites.
What do I need to change?
see all that TODO comment in your code? implement it. you must do this for it to work on modern versions of andorid
