Cordova - white screen after splash, no exceptions in console

I've been away from my Cordova app for a bit, but just did a fresh clone yesterday and noticed that it's got the "white screen of death" symptoms -- the splash screen displays, the program loads... and then I just get a blank screen. Some more details:

Has Cordova / PhoneGap done something recently that might be causing this? Any ideas on how to isolate this one? I'm really stumped.

Not really an answer, but I'll add it to the list of potential experiments here - I never worked out how this was happening, but it was resolved by deleting the entire platforms folder and node_modules, then re-adding the platform.

I have this situation and solved it.

In my case it was something similar to this code:

$scope.images.push({ id: i, src: "http://placehold.it/50x50" , pstb, trno});

The above code run well on android 7.0 but only white screen after splash on android 4.4.4

Changed to this:

$scope.images.push({ id: i, src: "http://placehold.it/50x50", pstb: pstb, trno: trno});

Run on all devices (at least all my devices)

I added these lines in config.xml

<preference name="SplashScreen" value="screen" />
<preference name="SplashScreenDelay" value="6000" />

I also have a black screen when I give screendelay as 3000.so I changed to 6000.I think cordova take some time to load your js,css and image files.

A missing <meta http-equiv="Content-Security-Policy"> tag on the head caused a white-screen in my case.

My problem was with ES6, it runs perfectly on iPhone and Android 6, but it doesn't work with Android 4 and 5.

The only fix that worked for me was found here: http://www.codingandclimbing.co.uk/blog/ionic-2-fix-splash-screen-white-screen-issue-14

basically edit your config.xml file. The splashscreen setup should look like this:

<preference name="ShowSplashScreen" value="true"/>
<preference name="SplashScreen" value="screen"/>
<preference name="SplashScreenDelay" value="30000"/>
<preference name="AutoHideSplashScreen" value="false"/>
<preference name="SplashShowOnlyFirstTime" value="false"/>
<preference name="FadeSplashScreen" value="false"/>
<feature name="SplashScreen">
    <param name="android-package" value="org.apache.cordova.splashscreen.SplashScreen"/>
</feature>

In my case, I accidentally commented the state definition in app.js.

Well that was ugly. It turned out that there was an exception being thrown, it was just being thrown too early for the browser dev tools to pick it up (Safari, Chrome for iOS and Android, respectively). The exception did show up when I ran things through the browser target (cordova platform add browser, etc.) So that browser platform is useful for something I guess. :-)

In my case, the cordova-sqlite-storage plugin had made a breaking API change that broke the code when I updated everything. The solution was to pin the plugin to an earlier version in the config.xml file.

So, lessons learned:

  • If you suspect there's an exception being thrown during startup, you can use the browser platform to track it down.
  • Pin your plugins to a specific version using the spec parameter in the config.xml. This will save you some heartache in the future.
  • [another option from @jcesarmobile, below] hitting refresh in the browser dev tools will also kick out the exception. Nice!

I'll be going back in to the config.xml and pinning the other items -- and doing some cleanup as suggested above. Thanks again, everyone.

I manged to run your app this are the steps I followed.

1) First you need to declare Splash screen preference along with splash screen plugin location in your config.xml. This is what I think you are missing

<preference
    name="SplashScreen"
    value="screen" />
<preference
    name="AutoHideSplashScreen"
    value="true" />
<preference
    name="SplashScreenDelay"
    value="5000" />

<feature name="SplashScreen" >
    <param
        name="android-package"
        value="org.apache.cordova.splashscreen.SplashScreen" />

    <param
        name="onload"
        value="true" />
</feature>

2) Declare your splash screens images in config.xml ,which you have already done.

I suggest you to keep images in default density folders of android project (ldpi,mdpi,hdpi,xhdpi etc) instead of screen/android folder as it will simplifiy your project structure.

    <!-- you can use any density that exists in the Android project -->
    <splash
        density="land-hdpi"
        src="res/drawable-land-hdpi/splash.png" />
    <splash
        density="land-ldpi"
        src="res/drawable-land-ldpi/splash.png" />
    <splash
        density="land-mdpi"
        src="res/drawable-land-mdpi/splash.png" />
    <splash
        density="land-xhdpi"
        src="res/drawable-land-xhdpi/splash.png" />
    <splash
        density="port-hdpi"
        src="res/drawable-hdpi/splash.png" />
    <splash
        density="port-ldpi"
        src="res/drawable-ldpi/splash.png" />
    <splash
        density="port-mdpi"
        src="res/drawable-mdpi/splash.png" />
    <splash
        density="port-xhdpi"
        src="res/drawable-xhdpi/splash.png" />
</platform>

3) Add Splash screen plugin class into your android project structure under org.apache.cordova.splashscreen package or install splash screen Cordova plugin

https://cordova.apache.org/docs/en/3.1.0/cordova/splashscreen/splashscreen.html

4) Final and most important step you must have cordova.js in your www folder

Cordova.js in assets

And after that I was able to run your web app

enter image description here

I am android developer I guess something similar you might need to do for iOS

You should install the splash-screen plugin for both iOS and Android to work properly if you are adding splash in config.xml. or else without splash-screen plugin what you could try to do is making an splash screen with HTML, divide your body in 2 parts: content and login. Then you set the content style display: none. When the app is done loading you just set loading screen display: none and content screen display: block or whatever you want

And you missing below preferences in your config.xml

<preference name="SplashScreenDelay" value="3000" />
<preference name="SplashMaintainAspectRatio" value="true|false" />
<preference name="SplashShowOnlyFirstTime" value="true|false" />

Try adding this preference to your config.xml, maybe this is the problem

<preference name="AutoHideSplashScreen" value="true"/>

I had a similar problem while using cordova with ember.js. It was about the url change strategy of my application.

Have a look on this answer, it maybe related with your problem.
