[android] Passing arguments to AsyncTask, and returning results

You can receive returning results like that: AsyncTask class

@Override
protected Boolean doInBackground(Void... params) {
    if (host.isEmpty() || dbName.isEmpty() || user.isEmpty() || pass.isEmpty() || port.isEmpty()) {
        try {
            throw new SQLException("Database credentials missing");
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }

    try {
        Class.forName("org.postgresql.Driver");
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    }

    try {
        this.conn = DriverManager.getConnection(this.host + ':' + this.port + '/' + this.dbName, this.user, this.pass);
    } catch (SQLException e) {
        e.printStackTrace();
    }

    return true;
}

receiving class:

_store.execute();
boolean result =_store.get();

Hoping it will help.
