Question

i created a splash screen but when i launch my app the splash screen does not show, just a black screen. however, after my timer for the splash screen ends, my menu comes up. in the graphical layout of my splashscreen.xml, the splash screen image show. but when run, it does not. all is normal except for my splash screen…

code for myMain.java:

package com.immrroj.firstapp;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;

public class myMain extends Activity
{

@Override
protected void onCreate(Bundle savedInstanceState)
{
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.splashscreen);
    Thread splashtimer = new Thread()
    {
        @Override
        public void run()
        {
            try
            {
                int timer = 0;
                while (timer < 5000)
                {
                    sleep(100);
                    timer = timer + 100;
                }
                startActivity(new Intent("com.immrroj.firstapp.CLEARSCREEN"));
            } catch (InterruptedException e)
            {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

            finally
            {
                finish();
            }
        }
    };
    splashtimer.run();
}

@Override
protected void onDestroy()
{
    // TODO Auto-generated method stub
    super.onDestroy();
}

@Override
protected void onResume()
{
    // TODO Auto-generated method stub

Got it.

Downloaded your .rar and gave it a look. Turns out there was something wrong with your Thread. I don’t know exactly what, but it was causing the layout not to be properly loaded (probably because you made it sleep for 100 ms, then wake up, check a variable, and sleep again for 100 ms over and over).

I changed your thread with the following code and now it works perfectly on my phone:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.splashscreen);

        Thread timer = new Thread() {
            // Thread to show the splash screen, then launch the main screen
            @Override
            public void run() {
                try {
                    sleep(2500); // set this to how long you want to wait before
                                    // showing the main screen
                } catch (InterruptedException e) {
                    e.printStackTrace();
                } finally {
                    Intent mainScreen = new Intent(
                            "com.immrroj.firstapp.CLEARSCREEN");
                    startActivity(mainScreen);
                }
            }
        };
        timer.start();
    }

You can leave all the other onStart, onPause etc methods out, you’re not using those in a splash screen anyway.

I uploaded the edited code here: Download

Good luck with your app!
