The Return Type Is Incompatible With Asynctask

I'm trying to capture the response of httpclient using AsyncTask but throws me the following error verifying any incompatibility doInBackground in the String: 'the return type is

Solution 1:

the problem here is that AsyncTask Extensions are generic and need three types: AsyncTask<Params, Progress, Result>AsyncTask which may be Void or a class, but not primitive data types.

so what happens is you told the compiler that doInBackground returns a primitive var but it was expecting an instance of the class String.

So use doInBackground function as

@OverrideprotectedStringdoInBackground(String... params) {
                // TODO Auto-generated method stubString result = insertar();

                return result;
            }

Edit

In AsyncTask you are returning Boolean and in doInBackground return type is String,so

change it to String because you want String value from insertar() function,i.e. change

classInsertarextendsAsyncTask<String,String,Boolean>{

to

classInsertarextendsAsyncTask<String,String,String>{

and

@OverrideprotectedvoidonPostExecute(Boolean result) {

        }

to

@OverrideprotectedvoidonPostExecute(String result) {

        }
