requestLocationUpdates is not working on Android 11 & 12

I'm trying to call my latitude & longitude data of the phone every 5 seconds.
This code worked well for Android 9 and 10, but it is not working for 11 and 12.
The initial location is updated but the following location is not updated at all.
FINE and COARSE location permissions are requested. What could be the problem?
if (!isGPSEnabled && !isNetworkEnabled) {
lat = 0;
lon = 0;
} else {
this.isGetLocation = true;
// GPS
if (isGPSEnabled) {
locationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER,
0,
0, this);
if (locationManager != null) {
location = locationManager
.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if(location != null && location.getTime() > Calendar.getInstance().getTimeInMillis() - 5000) {
gpsUse = true;
}
if (location != null) {
lat = location.getLatitude();
lon = location.getLongitude();
}
}
}
if (isNetworkEnabled) {
locationManager.requestLocationUpdates(
LocationManager.NETWORK_PROVIDER,
0,
0, this);
if (locationManager != null) {
location4 = locationManager
.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
if(location4 != null && location4.getTime() > Calendar.getInstance().getTimeInMillis() - 5000) {
networkUse = true;
}
if (location4 != null) {
lat = location4.getLatitude();
lon = location4.getLongitude();
}
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
I added the code of AndroidManifest.xml

eaccess permission denied even with permissions granted

I created a simple test app where I decode a file path into a Bitmap. But even if the permissions are granted it still gives permission denied into the console.
Here's the main activity code:
public class MainActivity extends AppCompatActivity {
public static final String TAG = "DEBUG_";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ImageView imageView = findViewById(R.id.image_view);
if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED ||
ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
imageView.setImageBitmap(BitmapFactory.decodeFile("/storage/emulated/0/DCIM/Camera/IMG_20200118_175558.jpg"));
}
}
}
And here's the manifest file:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.frakm.imagepickertesting">
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

<application

<activity android:name=".MainActivity">

<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />

How to access SYSTEM_ALERT_WINDOW permission run time?

This is my code for reference. I have added the run time permission code and system granting the permission but again it gives an error:

setMyLocation Button will not pop up when application loads

I'm trying to display the basic setMyLocation Button when my application loads the map but every time I do so the application crashes and says java.lang.SecurityException: my location requires permission ACCESS_FINE_LOCATION or ACCESS_COARSE_LOCATION
at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:3288) I have the necessary permissions included in the manifest
public class MainActivity extends AppCompatActivity {
public GoogleMap map;
Location location;
//double lat, longit;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
map.setMyLocationEnabled(true);
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

To obtain the current location

I am using the below code to obtain the location of a user
public class MainLocation extends Application implements LocationListener {
protected LocationManager locationManager;
protected LocationListener locationListener;
protected Context context;
String lat;
String provider;
protected String latitude, longitude;
protected boolean gps_enabled, network_enabled;
#Override
public void onCreate() {
super.onCreate();
Log.e("Location", "here");
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && checkSelfPermission(Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
// public void requestPermissions(#NonNull String[] permissions, int requestCode)
// 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 Activity#requestPermissions for more details.
return;
}
}
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
}
#Override
public void onLocationChanged(Location location) {
Log.e("Location", "" + location.getLatitude());
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
Log.e("Location Status", "" + provider + " " + status + " " + extras);
}
#Override
public void onProviderEnabled(String provider) {
Log.e("Location", "Enabled");
}
#Override
public void onProviderDisabled(String provider) {
Log.e("Location","Disabled"+provider);
}
}
but here the onLocationChanged function is never getting called, so i m not able fetch the location. So how can i get the location?
In the logcat, the info tab is showing the latitude and longitude under the title onLocationReceived".

The Google Play services location APIs are preferred over the Android framework location APIs (android.location) as a way of adding location awareness to your app.
You can find the example how to use it right here.
P.S. Don't forget to check if permissions granted on your device, if you added permissions into manifest file...
