Post value to server when no internet connection android studio - sqlite

Question

I'm trying to send a value to the server when the connection doesn't exist, when it connects to the internet it runs fine and is saved to the server and sqlite. but the problem arises when switching state from offline to online. I send one value to the server when the connection is offline but when the state moves to online the value I sent earlier becomes multiple on the server while in the sqlite database only one value is stored.
this is my network state checker class
public class NetworkStateCheckerNama extends BroadcastReceiver {
//context and database helper object
private Context context;
private Database db;
ApiRequestData apiRequestData;
#Override
public void onReceive(Context context, Intent intent) {
this.context = context;
apiRequestData = ServiceGenerator.createBaseService(this.context, ApiRequestData.class);
db = new Database(context);
ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
//if there is a network
if (activeNetwork != null) {
//if connected to wifi or mobile data plan
if (activeNetwork.getType() == ConnectivityManager.TYPE_WIFI || activeNetwork.getType() == ConnectivityManager.TYPE_MOBILE) {
//getting all the unsynced user
Cursor cursor2 = db.getUnsyncedNama();
if (cursor2.moveToFirst()) {
do {
//calling the method to save the unsynced name to MySQL
Nama(
cursor2.getString(cursor2.getColumnIndexOrThrow(Database.KOLOM_NAMA_COBA)),
cursor2.getString(cursor2.getColumnIndexOrThrow(Database.KOLOM_NIP_COBA))
);
} while (cursor2.moveToNext());
}
}
}
}
private void Nama(final String nama,final String nip) {
//Call call = retrofit.create(APIInterface.class).saveName(name);
Call call = apiRequestData.nama_query(nama,nip);
call.enqueue(new Callback<Responses>() {
#Override
public void onResponse(Call<Responses> call, Response<Responses> response) {
if (response.code() == 200){
db.updateNamaStatus(nip, MainActivity.NAME_SYNCED_WITH_SERVER);
//sending the broadcast to refresh the list
context.sendBroadcast(new Intent(MainActivity.DATA_SAVED_BROADCAST_MAIN));
}
}
#Override
public void onFailure(Call<Responses> call, Throwable t) {
}
});
}
