“getText” syntax is not working and it’s showing error.
@Override
protected String doInBackground(String... params)
{
String usernam = username.getText().toString();
String passwordd = password.getText().toString();
if(usernam.trim().equals("")|| passwordd.trim().equals(""))
{
z = "Please enter Username and Password";
}
else
{
try
{
con = connectionclass(un, pass, db, ip);
if (con == null)
{
z = "Check Tour Internet Access!";
}
else
{
String query = "select * from login where user_name= '" + usernam.toString() + "' and pass_word = ' " + passwordd.toString();
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery(query);
if(rs.next())
{
z = "Login successful";
isSuccess = true;
con.close();
}
else
{
z = "Invalid Credentials";
isSuccess = false;
}
}
}
catch (Exception ex)
{
isSuccess = false;
z = ex.getMessage();
}
}
return z;
}

Answer
private class MyAsyncTask extends AsyncTask<String, Void, String> {
private String username="";
private String password="";
public MyAsyncTask(String user, String pass)
{
this.username = user;
this.password = pass;
}
protected void onPreExecute() {
}
protected Bitmap doInBackground(String... strings) {
// Some long-running task like downloading an image.
// No UI related work here.. or else it will crash
}
protected void onPostExecute(Bitmap result) {
// This method is executed in the UIThread
// with access to the result of the long running task
}
}
Now when calling the asynctask in your Activity do this
// Its inside the Activity Class
MyAsyncTask asd = new MyAsyncTask(username.getText().toString(),password.getText().toString());
asd.execute("");
Pass the values of the EditText while calling the AsyncTask itself in the activity
