java - How to show splash screen only when the app starts "fresh"?

Question

I want to show the splash screen only once during the Application life cycle. Here is my code:

SplashScreenActivity.java:

final int welcomeScreenDisplay = 3000;

Thread welcomeThread = new Thread() {

    int wait = 0;

    @Override
    public void run() {
        try {
            super.run();

            while (wait < welcomeScreenDisplay) {
                sleep(1000);
                wait += 1000;
            }
        } catch (Exception e) {
            System.out.println("EXc=" + e);
        } finally {

            // Start other Activity
            startActivity(new Intent(SplashScreenActivity.this,
                    MainActiviey.class));
            finish();
        }
    }
};
welcomeThread.start();

Manifest:

    <activity android:name=".SplashScreenActivity" android:label="test"
    android:noHistory="true"
        android:screenOrientation="portrait" android:configChanges="orientation|keyboardHidden|keyboard">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".MainActiviey" android:label="test"
         android:screenOrientation="portrait"
        android:configChanges="orientation|keyboardHidden|keyboard">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

The problem is if I press the hardware HOME botton to hide the app and open the App again at the application list. It will show the splash screen again (instead of showing the MainActivity). Is it possible to show splash screen only when the app starts "fresh" (not show at onresume() )? Thanks!

You can't have this intent for two activities:

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

Also you might want to hide the splash screen from the history stack in case you decided launch another activity inside it as per Ash suggestion.

You can use this flag on your activity tag:

android:noHistory="true"
