blank screen comes before splash

Question

The main problem is the splash screen appears after 2-3 seconds. Before splash screen a blank layout appears which I don't want. Otherwise it runs fine. Just want to remove the blank layout which appears before the splash page.

MainActivity:

public class MainActivity extends Activity {      private static String TAG = MainActivity.class.getName();     private static long SLEEP_TIME = 5; // Sleep for some time      @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);          this.requestWindowFeature(Window.FEATURE_NO_TITLE); // Removes title bar         this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);  // Removes notification bar          setContentView(R.layout.activity_main);          // Start timer and launch main activity         IntentLauncher launcher = new IntentLauncher();         launcher.start();     }      private class IntentLauncher extends Thread {          @Override         /**          * Sleep for some time and than start new activity.          */         public void run() {             try {                 // Sleeping                 Thread.sleep(SLEEP_TIME*1000);             } catch (Exception e) {                 Log.e(TAG, e.getMessage());             }              // Start main activity             Intent intent = new Intent(MainActivity.this, Login.class);             MainActivity.this.startActivity(intent);             MainActivity.this.finish();         }     }  } 

main layout

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:paddingBottom="@dimen/activity_vertical_margin"     android:paddingLeft="@dimen/activity_horizontal_margin"     android:paddingRight="@dimen/activity_horizontal_margin"     android:paddingTop="@dimen/activity_vertical_margin"     android:background="@drawable/splash"     tools:context=".MainActivity" >  </RelativeLayout>

Generally speaking, splash screens are not recommended for an app but if you really must.

Android will load a blank layout before it loads an activity layout based on the theme you have set for it. The solution is to set the theme of the splash activity to a transparent one.

Create a transparent theme in res/values/styles.xml

<?xml version="1.0" encoding="utf-8"?> <resources>    <style name="Theme.Transparent" parent="android:Theme">       <item name="android:windowIsTranslucent">true</item>       <item name="android:windowBackground">@android:color/transparent</item>       <item name="android:windowContentOverlay">@null</item>       <item name="android:windowNoTitle">true</item>       <item name="android:windowIsFloating">true</item>      <item name="android:backgroundDimEnabled">false</item>   </style> </resources> 

Then set the theme in your manifest

<activity android:name=".SplashActivity" android:theme="@style/Theme.Transparent"> ... </activity>

It's better to use a Themed background for your starting activity but if you don't want the blank screen appears before launching main activity you can define your activity like this:

Add android:windowDisablePreview to your AppTheme in res/values/styles.xml:

<?xml version="1.0" encoding="utf-8"?> <resources>    <style name="AppTheme" parent="android:Theme">         <item name="android:windowDisablePreview">true</item>   </style> </resources> 

Then set your activity theme in your manifest:

<activity android:name=".MainActivity" android:theme="@style/AppTheme"> ... </activity> 

P.S: Setting android:windowDisablePreview has no effect on your activity background, so you have nothing to worry.
