Question

This is my method in DBMethods class:

public void getResult(EditText keyWord2){

    EditText keyWord = null;

    String SQL ="localSearch.php?query="+keyWord.getText();
    mDb.rawQuery(SQL, null);
}

And this is my method in which I am opening Database and all that in webServices class.

public void startSearch(View v){

    keyWord = (EditText)findViewById(R.id.searchField);
        String data = null;
        DBMethods mDbHelper = new DBMethods(this);         
        mDbHelper.createDatabase();       
        mDbHelper.open(); 

        mDbHelper.getResult(keyWord);
        mDbHelper.close();

}

When I try to fetch data from the database by entering some keyword in the search bar, a force close error occurs.

Answer 1

EditText keyWord = null;

String SQL ="localSearch.php?query="+keyWord.getText();

Keyword is null, this will give null pointer exception.

I think your SQL variable must be

localSearch.php?query="+**keyWord2**.getText();
