I try to synchronize the contacts of the mobile device with a database in this case Postgresql, the way I do it does not seem to be the most convenient.

    public void sincronizarcontactos(){



// Se tiene permiso

final String projeccion = new String{ContactsContract.CommonDataKinds.Phone._ID,ContactsContract.Data.DISPLAY_NAME, ContactsContract.CommonDataKinds.Phone.NUMBER, ContactsContract.CommonDataKinds.Phone.NORMALIZED_NUMBER};

String selectionClause = ContactsContract.Data.MIMETYPE + "='" +

        ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE + "' AND "

        + ContactsContract.CommonDataKinds.Phone.NUMBER + " IS NOT NULL";

String sortOrder = ContactsContract.Data.DISPLAY_NAME + " ASC";



final Cursor c = getContentResolver().query(

        ContactsContract.Data.CONTENT_URI,

        projeccion,

        selectionClause,

        null,

        sortOrder);



HashSet<String> normalizedNumbersAlreadyFound = new HashSet<>();

int indexOfNormalizedNumber = c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NORMALIZED_NUMBER);

progreso= ProgressDialog.show(SincronizarActivity.this, "", "Sincronizando...", true);



int o=0;



while(c.moveToNext()){

    o++;

    progreso.show();

    String email=c.getString(0).replace(" ","_");

    String normalizedNumber = c.getString(indexOfNormalizedNumber);

    if(normalizedNumbersAlreadyFound.add(normalizedNumber)){

        String urlinsert="http://192.168.1.33/Agenda/insert_persona.php?name="+c.getString(0)+

                "&city=Paute&email="+email+"@gmail.com&phone="+c.getString(1)+"&mobile="+c.getString(2);



        JsonObjectRequest solicitud = new JsonObjectRequest(urlinsert,null, new Response.Listener<JSONObject>(){

            @Override

            public void onResponse(JSONObject datos) {

                Toast.makeText(SincronizarActivity.this, "Guardado", Toast.LENGTH_SHORT).show();

            }

        },new Response.ErrorListener(){

            @Override

            public void onErrorResponse(VolleyError error) {

                progreso.dismiss();

                Toast.makeText(SincronizarActivity.this, "Tuvimos un problema de conexión...", Toast.LENGTH_SHORT).show();

            }

        });

        VolleyRP.addToQueue(solicitud,request,this,volley);

    }



    if (o==projeccion.length){

        progreso.dismiss();

    }



}

progreso.dismiss();

Toast.makeText(SincronizarActivity.this, "Se han sicronizado sus contactos...", Toast.LENGTH_SHORT).show();

c.close(); }

As I say it does not seem to me to be the most correct way, I would like you to help me to get them to synchronize automatically, example as in the photo ...

The query code looks ok, I think the question you're asking is "how do I run a contact sync operation integrated into Android's ecosystem".

The answer would by to create a Contacts SyncAdapter, see my answer to a similar question here: https://stackoverflow.com/a/44566012/819355
