You should not be creating a new thread on startup, instead you should create a view that does not have to wait for your resources to load, as detailed in this article: Splash Screens the Right Way.
As stated in the article, you should create a layer-list
drawable instead of a layout
XML file:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Fill the background with a solid color -->
<item android:drawable="@color/gray"/>
<!-- Place your bitmap in the center -->
<item>
<bitmap
android:gravity="center"
android:src="@mipmap/ic_launcher"/>
</item>
</layer-list>
Then create a theme using the drawable file as a background. I use the background
attribute instead of the windowBackground
attribute as suggested in the article, because background
takes the status and navigation bars into account, centering the drawable better. I also set windowAnimationStyle
to null
so that the splash screen does not animate the transition to the MainActivity
:
<resources>
<!-- Base application theme -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
</style>
<!-- Splash Screen theme -->
<style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
<item name="android:background">@drawable/background_splash</item>
<item name="android:windowAnimationStyle">@null</item>
</style>
</resources>
Then declare your theme in the manifest for your SplashActivity
:
<activity android:name=".SplashActivity"
android:theme="@style/SplashTheme">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
And finally all you have to do in your SplashActivity
is start your MainActivity
, and the splash screen will only show for as long as it takes for your app to configure:
public class SplashActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent intent = new Intent(this, MainActivity.class);
startActivity(intent);
finish();
}
}
