I want to send the location via message but sometimes it sends the message, sometimes it sends the null string and sometimes it does not send.

This is the button click on which I want to send the message to the
Recipient using the current location

 b.setOnClickListener(new View.OnClickListener() 
 String loc;
 @Override
 public void onClick(View view) 
 arrno[0]=num1;
 arrno[1]=num2;
 arrno[2]=num3;
 arrno[3]=num4;

 requestpermisson();
 for (int i = 0; i < arrno.length; i++) 
*here the getter data is stored in the loc String* 
 loc=getMyLocation();
 sendSMS(arrno[i], "I am in trouble :n"+"My current Address :"+loc);

 

This is just to show the message of the current location and the mobile
numbers
for testing

problem is that I get the location and it sends the SMS with location and sometimes I get a null string and sometimes it does not send

The SMS(maybe due to exceeding the message limit )

 Toast.makeText(getApplicationContext(), "" + num1 + "" + num2 + "" + num3 + "" + num4+" " +loc , Toast.LENGTH_LONG).show();
 
 );



 locationManager =(LocationManager) this.getSystemService(Context.LOCATION_SERVICE);

 locationListener=new LocationListener() 
 @Override
 public void onLocationChanged(Location location) 

 if(location!=null) 
 Geocoder geocoder = new Geocoder(getApplicationContext(), Locale.getDefault());
 try 
 List<Address> listAddresses = geocoder.getFromLocation(location.getLatitude(), location.getLongitude(), 1);


 if (listAddresses != null && listAddresses.size() > 0) 
 String address = "";

 if (listAddresses.get(0).getAddressLine(0) != null) 
 address += listAddresses.get(0).getAddressLine(0) + " ";
 

 if (listAddresses.get(0).getAddressLine(1) != null) 
 address += listAddresses.get(0).getAddressLine(1) + " ";

 

 if (listAddresses.get(0).getAdminArea() != null) 
 address += listAddresses.get(0).getAdminArea() + " ";
 

 if (listAddresses.get(0).getLocality() != null) 
 address += listAddresses.get(0).getLocality() + " ";
 





 // this will show you your current address
 Toast.makeText(MainActivity.this, address, Toast.LENGTH_SHORT).show();

 setMyLocation(address);


 


 catch (Exception e) 
 e.printStackTrace();
 
 
 else
 
 Toast.makeText(context, "no location found", Toast.LENGTH_SHORT).show();


 


 

 @Override

 if(ContextCompat.checkSelfPermission(this,Manifest.permission.ACCESS_FINE_LOCATION)!=PackageManager.PERMISSION_GRANTED)

 else
 
 locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
 








 }

 private static final int MY_PERMISSIONS_REQUEST_SEND_SMS = 1;

This is for requesting the permission

 public void requestpermisson() 
 if (ContextCompat.checkSelfPermission(this,
 Manifest.permission.SEND_SMS)
 != PackageManager.PERMISSION_GRANTED) 
 if (ActivityCompat.shouldShowRequestPermissionRationale(this,
 Manifest.permission.SEND_SMS)) 
 else 
 ActivityCompat.requestPermissions(this,
 new String[]Manifest.permission.SEND_SMS,
 MY_PERMISSIONS_REQUEST_SEND_SMS);
 
 
 






 @Override
 public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) 
 super.onRequestPermissionsResult(requestCode, permissions, grantResults);
 if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) 
 if(ContextCompat.checkSelfPermission(this,Manifest.permission.ACCESS_FINE_LOCATION)==PackageManager.PERMISSION_GRANTED) 

 locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
 
 

 

This is the function for sms sending

 public void sendSMS(String phoneno, String msg)
 Toast.makeText(getApplicationContext(),"In show m",Toast.LENGTH_SHORT).show();

 try
 SmsManager smsManager=SmsManager.getDefault();
 smsManager.sendTextMessage(phoneno,null,msg,null,null);
 Toast.makeText(getApplicationContext(),"message has been send to " +phoneno,Toast.LENGTH_SHORT).show();
 
 catch (Exception ex)
 Toast.makeText(getApplicationContext(),"sms not sent",Toast.LENGTH_SHORT).show();
