cordova-plugin-ionic-webview - custom scheme not working on Android

I am developing (and near to the release) of a Cordova App for iOS and Android.
I am trying to use cordova-plugin-ionic-webview in order to use the latest WebView engines.
I am able to use this plugin on iOS but on Android the App crashes on launch.
MY CONFIG.XML:
<allow-navigation href="cordovaios://*" />
<allow-navigation href="cordovaandroid://*" />
<plugin name="cordova-plugin-ionic-webview" spec="^4.0.0">
<variable name="ANDROID_SUPPORT_ANNOTATIONS_VERSION" value="27.+" />
</plugin>
<preference name="Hostname" value="my-backend-url-to-avoid-CORS.com" />
<preference name="iosScheme" value="cordovaios" />
<preference name="Scheme" value="cordovaandroid" />
<preference name="ScrollEnabled" value="true" />
<preference name="MixedContentMode" value="0" />
<preference name="AllowBackForwardNavigationGestures" value="true" />
<preference name="Allow3DTouchLinkPreview" value="false" />
<preference name="WKSuspendInBackground" value="false" />
<preference name="KeyboardAppearanceDark" value="false" />
LOGS:
5726-5770/mycertificate.enterprise D/SERVER: Handling local request: cordovaandroid://my-backend-url-to-avoid-CORS.com/static/js/10.601e7973.chunk.js

5726-5773/mycertificate.enterprise E/chromium: [ERROR:bad_message.cc(23)] Terminating renderer for bad IPC message, reason 123
NOTE:
This config works fine on iOS. On Android I can't use this plugin due to this Hostname/Origin issue.

That custom scheme does not appear to be supported (just try to find something alike that in the source code). It is also beyond my understanding, for what one even would even need to register a custom protocol handler, while never leaving that WebView? The usual purpose is: to open another application.
<preference name="Scheme" value="https" />
<allow-navigation href="https://my-backend-url-to-avoid-CORS.com/*"/>

Unfortunately there is a lot of mismatching between the Cordova Android Platform version and plugins versions, which lead to some waste of time for nothing. Said so, for similar problemas I had like this I simply fixed them downgrading the version of Cordova or Android or the Plugin (or use the same version of android the plugin is using in their code example).

Cordova Webview and Splashscreen dont work

I installed Cordova plugin:
cordova-plugin-crosswalk-webview
Everything works fine with this plugin, but then I installed
cordova plugin add cordova-plugin-splashscreen
for creating splashscreen. In file config.xml in widget section I put this code:
<preference name="SplashScreen" value="screen" />
<preference name="SplashScreenDelay" value="5000" />
<preference name="AutoHideSplashScreen" value="true" />
<preference name="ShowSplashScreenSpinner" value="false" />
Build was successful. After start application it shows splashscreen (for 5 second), but when splashscreen is disappear, it shows just white page instead my app. After I remove webview plugin - everyting works fine. How can I fix that problem?

splash screen is not showing on android

i have really searched about the problem but didn't find the correct solution that's why again here..
i have a Ionic+ Cordova project i want to show Splash Screen on android. project include a
res folder and inside that a drawable folder where i have placed my screen.png which i want to show.
but the problem is the file is not showing .
what is the problem how to show
i have include below line of code in config.xml which is inside of root folder
<preference name="SplashScreen" value="screen" />
<preference name="SplashScreenDelay" value="20000" />
<preference name="auto-hide-splash-screen" value="false" />
and my splash screen is here
platforms/android/res/drawable/screen.png
before app load a black than white backgound shows..

You need to install the splashscreen plugin in order to use it.
You can write the preferences in the config.xml, but I would recommand to do use the platform tag. Also make sure that you provide a splashscreen for each resolution in the drawables folder
<platform name="android">
<preference name="SplashScreen" value="screen" />
<preference name="SplashScreenDelay" value="1500" />
</platform>

Did you add the SplashScreen to AndroidManifest.xml ?

Limiting Android minsdk to 4x & up using Intel XDK development environment

I'm wanting to limit the android users (on google play store, etc.) to android 4.x & up.
I'm using the Intel XDK environment to develop an android app. It's being built with the cordova 3.x build process (in XDK) and I've setup the intelxdk.config.xml file as follows below.
The min sdk version is:
<preference name="android-minSdkVersion" value="14" />
However when I set it up in the Google Play Store it says that it will be compatible with android 1.6 & up?
I'm wondering if I'm missing something?
Any advice would be appreciated.
Thanks. The full android config is below:
<!-- Android specific configuration -->
<preference name="DisallowOverscroll" value="false"/>
<preference name="BackgroundColor" value="0xffffffff"/>
<preference name="SplashScreen" value="splash" />
<preference name="SplashScreenDelay" value="5000" />
<preference name="android-minSdkVersion" value="14" />
<preference name="android-targetSdkVersion" value="19" />
<preference name="android-permission" value="GET_TASKS" />
<preference name="android-permission" value="VIBRATE" />
<preference name="android-signed" value="true" />
<!--
<preference name="android-installLocation" value="<LOCATION>" />
<preference name="android-windowSoftInputMode" value="<INPUTMODE>" />
-->

I just got a message from the Intel XDK group -- they suggest upgrading to the latest (build 1199) version of XDK where the build doesn't require manually creating the intelxdk.config.xml file. I don't understand exactly what that fixed, but it resolved it ;)

How to really exit a cordova application?

I put this code in a cordova (3.4.0) app:
<preference name="exit-on-suspend" value="true" />
<preference name="keepRunning" value="false" />
but when I push my home button for quit, and push it again, I can see the app keep running in the list ! so, what is the good param?
