Question

I’m learning android and in a tutorial, to open a new screen they use

…

startActivity( new Intent("com.rob.minispy.sweet"));

( in main.java )

…

public class sweet extends Activity {

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

}

( in sweet.java )

…

and finally

<activity android:name=".sweet"
          android:label="@string/app_name">
    <intent-filter>
        <action android:name="android.intent.action.SWEET" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

( in the manifest )

now not only that it doesn’t really work and make the app crash, wouldn’t it be easier to do it simply by

setContentView(R.layout.splash);

from main.java or are there some downsides to that?

Thanks!

You have 2 ways to start the sweet activity

1. Change startActivity( new Intent("com.rob.minispy.sweet")); to startActivity( new Intent("android.intent.action.SWEET")); See more info here
2. startActivity(new Intent(this,sweet.class)); . This uses the form Intent(Context packageContext, Class<?> cls). More info here
