How To fix white screen on app Start up

Question

I have an android app which displays a white screen for 2 seconds on startup  My other apps don t do this  but this one does  I have also implemented a splashscreen with the hope that it would fix this  Should I increase my splash screen sleep time  Thanks

Put this in a custom style and it solves all the problems. Using the hacky translucent fix will make your task bar and nav bar translucent and make the splashscreen or main screen look like spaghetti.

<item name="android:windowDisablePreview">true</item>

Below is the link that suggests how to design Splash screen  To avoid white black background we need to define a theme with splash background and set that theme to splash in manifest file   https   android jlelse eu right-way-to-create-splash-screen-on-android-e7f1709ba154  splash background xml inside res drawable folder   lt  xml version    1 0  encoding    utf-8   gt    lt layer-list xmlns android    http   schemas android com apk res android  gt     lt item android drawable     color colorPrimary      gt     lt item gt    lt bitmap  android gravity    center     android src     mipmap ic launcher      gt    lt  item gt    lt  layer-list gt    Add below styles   lt  -- Base application theme  -- gt       lt style name  AppTheme  parent  Theme AppCompat Light DarkActionBar  gt           lt  -- Customize your theme here  -- gt           lt item name  colorPrimary  gt  color colorPrimary lt  item gt           lt item name  colorPrimaryDark  gt  color colorPrimaryDark lt  item gt           lt item name  colorAccent  gt  color colorAccent lt  item gt       lt  style gt       lt  -- Splash Screen theme  -- gt       lt style name  SplashTheme  parent  Theme AppCompat NoActionBar  gt           lt item name  android windowBackground  gt  drawable splash background lt  item gt       lt  style gt    In Manifest set theme as shown below   lt activity             android name   SplashActivity              android theme   style SplashTheme  gt               lt intent-filter gt                   lt action android name  android intent action MAIN    gt                   lt category android name  android intent category LAUNCHER    gt               lt  intent-filter gt       lt  activity gt

It can be fixed by setting the theme in your manifest as    lt activity         android name   MySplashActivityName          android theme   android style Theme Translucent NoTitleBar   gt    lt intent-filter gt        lt action android name  android intent action MAIN    gt        lt category android name  android intent category LAUNCHER    gt   lt  intent-filter gt   lt  activity gt    and after that if you are getting java lang IllegalStateException  You need to use a Theme AppCompat theme  or descendant  with this activity  then you may need to extend Activity instead of AppCompatActivity in your MySplashActivity   Hope it helps

Just mention the transparent theme to the starting activity in the AndroidManifest xml  file    Like    lt activity         android name  first Activity Name          android theme   android style Theme Translucent NoTitleBar   gt    lt intent-filter gt               lt action android name  android intent action MAIN    gt                lt category android name  android intent category LAUNCHER    gt           lt  intent-filter gt    lt  activity gt    and extend that screen with Activity class in place of AppCompatActivity   like    public class SplashScreenActivity extends Activity     ----YOUR CODE GOES HERE----

Like you tube   initially they show icon screen instead of white screen  And after 2 seconds shows home screen   first create an XML drawable in res drawable    lt  xml version  1 0  encoding  utf-8   gt   lt layer-list xmlns android  http   schemas android com apk res android  gt        lt item         android drawable   color gray   gt        lt item gt           lt bitmap             android gravity  center              android src   mipmap ic launcher   gt       lt  item gt    lt  layer-list gt    Next  you will set this as your splash activity   s background in the theme  Navigate to your styles xml file and add a new theme for your splash activity   lt resources gt        lt  -- Base application theme  -- gt       lt style name  AppTheme  parent  Theme AppCompat Light DarkActionBar  gt           lt  -- Customize your theme here  -- gt       lt  style gt        lt style name  SplashTheme  parent  Theme AppCompat NoActionBar  gt           lt item name  android windowBackground  gt  drawable background splash lt  item gt       lt  style gt    lt  resources gt    In your new SplashTheme  set the window background attribute to your XML drawable  Configure this as your splash activity   s theme in your AndroidManifest xml    lt activity     android name   SplashActivity      android theme   style SplashTheme  gt       lt intent-filter gt           lt action android name  android intent action MAIN    gt            lt category android name  android intent category LAUNCHER    gt       lt  intent-filter gt   lt  activity gt    This link gives what you want  step by step procedure  https   www bignerdranch com blog splash-screens-the-right-way   UPDATE   The layer-list can be even simpler like this  which also accepts vector drawables for the centered logo  unlike the  lt bitmap gt  tag     lt layer-list xmlns android  http   schemas android com apk res android  gt       lt  -- Background color -- gt       lt item android drawable   color gray   gt        lt  -- Logo at the center of the screen -- gt       lt item         android drawable   mipmap ic launcher          android gravity  center   gt   lt  layer-list gt

Try the following code    lt  -- Base application theme  -- gt   lt style name  AppTheme  parent  Theme AppCompat Light NoActionBar  gt       lt  -- Customize your theme here  -- gt       lt item name  colorPrimary  gt  color colorPrimary lt  item gt       lt item name  colorPrimaryDark  gt  color colorPrimaryDark lt  item gt       lt item name  colorAccent  gt  color colorAccent lt  item gt       lt item name  android windowNoTitle  gt true lt  item gt       lt item name  android windowActionBar  gt false lt  item gt       lt item name  android windowFullscreen  gt true lt  item gt       lt item name  android windowContentOverlay  gt  null lt  item gt       lt item name  android windowIsTranslucent  gt true lt  item gt   lt  style gt    This code works for me and will work on all Android devices

Both properties works use any one of them        lt style name  AppBaseThemeDark  parent   style Theme AppCompat  gt               lt  --your other properties -- gt               lt  -- lt item name  android windowDisablePreview  gt true lt  item gt -- gt               lt item name  android windowBackground  gt  null lt  item gt               lt  --your other properties -- gt       lt  style gt

White background is caused because of the Android starts while the app loads on memory  and it can be avoided if you just add this 2 line of code under SplashTheme    lt item name  android windowDisablePreview  gt true lt  item gt   lt item name  android windowIsTranslucent  gt true lt  item gt

User · Answer

The white background is coming from the Apptheme You can show something useful like your application logo instead of white screen it can be done using custom theme in your app Theme just add   android windowBackground      attribute  The attribute value may be a image or layered list or any color

This is my AppTheme on an example app    lt style name  AppTheme  parent  Theme AppCompat Light DarkActionBar  gt       lt item name  android windowIsTranslucent  gt true lt  item gt       lt item name  colorPrimary  gt  color colorPrimary lt  item gt       lt item name  colorPrimaryDark  gt  color colorPrimaryDark lt  item gt       lt item name  colorAccent  gt  color colorAccent lt  item gt   lt  style gt    As you can see  I have the default colors and then I added the android windowIsTranslucent and set it to true   As far as I know as an Android Developer  this is the only thing you need to set in order to hide the white screen on the start of the application
