Answer 1

The mistake you are doing here is you are dumping specific time into your code You never know how much it will take to get response. You should follow following approach

Step 1 Show progress dialog on screen

Step 2 Let download take its own time.But it should be done in new thread

Step 3 Once download is complete it will raise message that task is done,now remove that progress dialog and proceed.

I am pasting sample code here.Hope it will help you.

package com.android.myApps;

import android.app.Activity;
import android.app.ProgressDialog;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;

public class MainScr extends Activity
{
    private Handler handler;
    private ProgressDialog progress;
    private Context context;

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        context = AncActivity.this;
        progress = new ProgressDialog(this);
        progress.setTitle("Please Wait!!");
        progress.setMessage("Wait!!");
        progress.setCancelable(false);
        progress.setProgressStyle(ProgressDialog.STYLE_SPINNER);

        handler = new Handler()
        {

            @Override
            public void handleMessage(Message msg)
            {
                progress.dismiss();
                Intent mainIntent = new Intent(context, Category.class);
                startActivity(mainIntent);
                super.handleMessage(msg);
            }

        };
        progress.show();
        new Thread()
        {
            public void run()
            {
                // Write Your Downloading logic here
                // at the end write this.
                handler.sendEmptyMessage(0);
            }

        }.start();

    }

}
