How To fix white screen on app Start up?

AndroidSplash ScreenApp Startup

Android Problem Overview

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.

Solution 1 - Android

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>

Solution 2 - Android

Just mention the transparent theme to the starting activity in the AndroidManifest.xml file.

Like:

<activity
        android:name="first Activity Name"
        android:theme="@android:style/Theme.Translucent.NoTitleBar" >
 <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

and extend that screen with Activity class in place of AppCompatActivity.

like :

public class SplashScreenActivity extends Activity{

  ----YOUR CODE GOES HERE----
}

Solution 3 - Android

enter image description 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.

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:drawable="@color/gray"/>

    <item>
        <bitmap
            android:gravity="center"
            android:src="@mipmap/ic_launcher"/>
    </item>

</layer-list>

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

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
    </style>

    <style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
        <item name="android:windowBackground">@drawable/background_splash</item>
    </style>

</resources>

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:

<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>

UPDATE:

The layer-list can be even simpler like this (which also accepts vector drawables for the centered logo, unlike the <bitmap> tag):

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
	<!-- Background color -->
	<item android:drawable="@color/gray"/>

	<!-- Logo at the center of the screen -->
	<item
		android:drawable="@mipmap/ic_launcher"
		android:gravity="center"/>
</layer-list>

Solution 4 - Android

Make a style in you style.xml as follows :

<style name="Theme.Transparent" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowActionBar">false</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowIsTranslucent">true</item>
</style>

and use it with your activity in AndroidManifest as:

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

You should read this great post by Cyril Mottier: Android App launching made gorgeous

You need to customise your Theme in style.xml and avoid to customise in your onCreate as ActionBar.setIcon/setTitle/etc.

Solution 6 - Android

This is my AppTheme on an example app:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="android:windowIsTranslucent">true</item>
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

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.

Solution 7 - Android

Both properties works use any one of them.

    <style name="AppBaseThemeDark" parent="@style/Theme.AppCompat">
            <!--your other properties -->
            <!--<item name="android:windowDisablePreview">true</item>-->
            <item name="android:windowBackground">@null</item>
            <!--your other properties -->
    </style>

Solution 8 - Android

The user543 answer is perfect

<activity
        android:name="first Activity Name"
        android:theme="@android:style/Theme.Translucent.NoTitleBar" >
 <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

But:

You'r LAUNCHER Activity must extands Activity, not AppCompatActivity as it came by default!

Solution 9 - Android

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.

Solution 10 - Android

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

<?xml version=”1.0" encoding=”utf-8"?>
 <layer-list xmlns:android=”http://schemas.android.com/apk/res/android">
 
 <item android:drawable=”@color/colorPrimary” />
 
 <item>
 <bitmap
 android:gravity=”center”
 android:src=”@mipmap/ic_launcher” />
 </item>
 
</layer-list>

Add below styles

<!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>
    <!-- Splash Screen theme. -->
    <style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
        <item name="android:windowBackground">@drawable/splash_background</item>
    </style>

In Manifest set theme as shown below

<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>

Solution 11 - Android

i also had the same problem in one of my project. I resolved it by adding some following parameters in the theme provided to the splash screen.

<item name="android:windowFullscreen">true</item>
<item name="android:windowContentOverlay">@null</item>
<item name="android:windowIsTranslucent">true</item>

You can find the reason and resolution in this blog post written by me. Hope it helps.

Solution 12 - Android

It can be fixed by setting the theme in your manifest as

<activity
        android:name=".MySplashActivityName"
        android:theme="@android:style/Theme.Translucent.NoTitleBar" >
 <intent-filter>
     <action android:name="android.intent.action.MAIN" />
     <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

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!

Solution 13 - Android

you should disable Instant Run android studio Settings.

File>Settings>Build,Execution, Deployment>Instant Run unCheck all options shown there.

Note: White screen Issue due to Instant Run is only for Debug builds,this Issue will not appear on release builds.

Solution 14 - Android

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.

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

Solution 15 - Android

This solved the problem :

Edit your styles.xml file :

Paste the code below :

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="android:windowFullscreen">true</item>
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:windowIsTranslucent">true</item>
    </style>

</resources>

And don't forget to make the modifications in the AndroidManifest.xml file. (theme's name)

Be careful about the declaration order of the activities in this file.

Solution 16 - Android

I encountered a similar problem and to overcome it, I implemented the code below in styles, i.e res->values->styles->resource tag 
<item name="android:windowDisablePreview">true</item>

Here is the whole code:

<style name="SplashTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowDisablePreview">true</item>
</style>

Solution 17 - Android

Try the following code:

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowActionBar">false</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowIsTranslucent">true</item>
</style>

This code works for me and will work on all Android devices.

Solution 18 - Android

Its Solution is very Simple!

There are Three Basic Reasons for This problem

  1. You are doing Heavy / Long running / Complex task in onCreateVeiw Function.
  2. If your are using Thread. Then Thread Sleep time may be very large.
  3. If You are using any Third Party library. Which is initialize at app start up time it may leads this problem.

Solutions:

Solution 1:

  Remove the Heavy Task from onCreateView() function and place it some where appropriate place.

Solution 2:

  Reduce the Thread Sleep time.

Solution 3:

  Remove the Third party library at app initialize at implement them with some good strategy.

> In my Case i am using Sugar ORM which leads this problem.
