Question

I have splash screen in an application. When user is at home screen and presses the back button; an alert dialog with “Do you want to exit?” is appeared and if users slects OK then moveTaskToBack(true); is called: and the app will exit. But on immediate launch of the application the splash screen is not shown. How to show splash screen on every launch of the application?

Answer 1

A few pointers on how to make a splash screen.

Say we have SplashActivity and HomeActivity.

SplashActivity should be your launcher activity (in the manifest).

<intent-filter>
      <action android:name="android.intent.action.MAIN" />

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

When you start HomeActivity you should call finish() on SplashActivity so that you wouldn’t return to it upon clicking the back button.

In HomeActivity when you intercept the back button to show the dialog, don’t call moveTaskToBack(true); on OK because this only moves your application to the background and doesn’t terminate it.

You should call finish() instead. And since you already called finish on SplashActivity, the only activity left is HomeActivity, so your application will close.
