Question

I have a problem with my app, before it was showing up in my emulator. After I unlocked it i could see it and click on it. But now, it’s not showing. I googled for almost hours but to no avail. Please I need your help so I can move on. Thanks. My manifest file seems okay, no error. And my source codes don’t also have errors.

Splash.java

public class Splash extends Activity{

    //MediaPlayer ourSong; // for our splash background song

    @Override
    protected void onCreate(Bundle iHF) {
        super.onCreate(iHF);
        setContentView(R.layout.splash);

            Thread timer = new Thread(){
                public void run(){
                    try{
                        sleep(1000); // sleeps/delays for 1 second
                    } // end try
                    catch(InterruptedException e){
                        e.printStackTrace();
                    }finally{
                        // this is going to create new intent activity for Ihealthfirst
                        // based on the action name (com.fps.ihealthfirst.IHEALTHFIRST)
                        Intent openIHealthFirst = new Intent("com.fps.iHealthFirst.IHEALTHFIRSTACTIVITY");
                        startActivity(openIHealthFirst);
                    }// end finally
                } // end run method
            }; // end thread

            timer.start();
        } // end onCreate method

    @Override
    protected void onPause() {
        super.onPause();
        finish();
    }



    } // end Splash class

Answer 1

Try replacing this line in your manifest:

<category android:name="android.intent.category.DEFAULT"/>

to this:

<category android:name="android.intent.category.LAUNCHER"/>

As it is now, you don’t have a launcher activity defined. If you wish to keep the DEFAULT option, you can add the line I posted rather than replacing it.
