Add android X support

[vtrifonov]

Add androidX support.
In order to turn it on you need to add in the app.gradle file:

project.ext.useAndroidX = true

You can setandroidx.legacy:legacy-support-v4 (replaces com.android.support:support-v4) , androidx.appcompat:appcompat (eplaces com.android.support:appcompat-v7) and com.google.android.material:material (replaces com.android.support:design) versions setting the following variables:

project.ext.androidXLegacy = "1.0.0"
project.ext.androidXAppCompat = "1.1.0-alpha01"
project.ext.androidXMaterial = "1.1.0-alpha01"

Have in mind that in order to make the application work with android X you'll need to have a version of tns-core-modules and all the plugins you use which works with android X

@vtrifonov there are some missing pieces. In here
this:

codeTuples.add(new Tuple2<String, String>('android\\.support\\.multidex\\.MultiDex', 'androidx.multidex.MultiDex'))

        codeTuples.each { tuple ->
            ant.replaceregexp(match: tuple.first, replace: tuple.second, flags: 'g', byline: true) {
                fileset(dir: "$projectDir/src/main/java/com/tns/", includes: '*.java')
            }
        }

is needed to also update this file.

I successfully build using that change

Thanks for your feedback! We’ve added the update from above.

I try to use Material DateTime Picker library (it worked fine until lib version 3.6.4)

dependencies {
    implementation "com.wdullaer:materialdatetimepicker:4.1.2"
}

But looks like it use AndroidX, so build failed with error:

/path_to_project/platforms/android/app/src/main/AndroidManifest.xml:22:18-91 Error:
        Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91
        is also present at [androidx.core:core:1.1.0-alpha01] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
        Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:21:2-44:16 to override.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91

        Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:21:2-44:16 to override.

I've tried to add such lines to app.gradle, but build still failed:

project.ext {
  useAndroidX = true
}

Suggestion: add 'tools:replace="android:appComponentFactory"'... don't work too.
I have NS5.2.0
How should I configure my project to work with this lib?

@webleaf currently the tns-core-modules doesn't support AndroidX, so you won't be able to use it in a NativeScript application. The support in the modules would come in one of our next releases.
