KeyDispatchTimedOut Error, when cliced a button to start an activity

Question

I am trying to retrieve values from a column in SQLite table and store it in an array. I have to start that activity from a another activity by clicking a button. But unfortunately, when I click that button, I am getting KeyDisplatchTimedOut error, which stopped my application unexpectedly.

This is my logcat -

This is the way I am calling that activity -

activity1.java:

alert_menu = (Button) findViewById(R.id.alert_menu);
            alert_menu.setOnClickListener(new View.OnClickListener() {
                public void onClick(View v) {
                    Intent i = new Intent(settings.this,Dialog.class);
                        startActivity(i);
                    }
                }); 

Dialog.java:

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_dup);

for(int i =1;i<=info.getrowcountofpersons();i++) 
{
    items[i-1]=info.getPersonList(i); //this method will return each person name and will be stored in items[] array
    System.out.println("The list items are:"+items[i-1]); 
    Toast.makeText(getApplicationContext(), items[i-1], Toast.LENGTH_LONG).show();

}
}

But instead of doing for loop, and initializing the array as private String[] items = {"Warrior","Archer","Wizard"};, the dialog is shown up and I am not getting that error. What might be the problem here?

Thanks in advance.

I think you are click the button within retrieving data from sqlite process completed. So you have to wait until the process completed. Its better to use AsyncTask to retrieve data from SQLite. For more detail refer this thread.
