Manol Donev cf034dd04d feat(android): migrate to support library apis (#6129) 
Switch Activity / Fragment / FragmentManager implementation from native framework to support library APIs

BREAKING CHANGE:


NativeScript core framework now extends support library APIs versus native framework classes as per Google's latest guidelines:
- NativeScript activities now extend `android.support.v7.app.AppCompatActivity` (vs android.app.Activity)
- NativeScript fragments now extend `android.support.v4.app.Fragment` (vs android.app.Fragment)
- NativeScript now works internally with `android.support.v4.app.FragmentManager` (vs android.app.FragmentManager) 

The implications of these changes should be mostly transparent to the developer except for the fact that the support library Fragment / FragmentManager work with Animation APIs versus Animator APIs.

For Android API Levels lower than 28 the new Fragment API uses a different fragment enter animation by default. You can customise the transition per navigation entry or globally via the [navigation transitions API](https://docs.nativescript.org/core-concepts/navigation#navigation-transitions)
Before:
Default fragment enter animation was fade animation

After:
Default fragment enter animation for API levels lower than 28 is now a fast "push fade" animation; default fragment enter animation for API levels equal to or greater than 28 remains fade animation

Before:
AndroidFragmentCallbacks interface exposed the following `onCreateAnimator(...)` method
``` ts
export interface AndroidFragmentCallbacks {
    onCreateAnimator(fragment: any, transit: number, enter: boolean, nextAnim: number, superFunc: Function): any;
    // ...
}
```

After:
AndroidFragmentCallbacks interface now exposes the following `onCreateAnimation(...)` method instead (and `onCreateAnimator(...)` is now removed)
``` ts
export interface AndroidFragmentCallbacks {
    onCreateAnimation(fragment: any, transit: number, enter: boolean, nextAnim: number, superFunc: Function): any;
    // ...
}
```

Before:
Transition class exposed the following abstract `createAndroidAnimator(...)` method
``` ts
export class Transition {
    public createAndroidAnimator(transitionType: string): any;
    // ...
}
```

After:
Transition class now exposes the following abstract `createAndroidAnimation(...)` method instead (and `createAndroidAnimation(...) is now removed)
``` ts
export class Transition {
    public createAndroidAnimation(transitionType: string): any;
    // ...
}
```

To migrate the code of your custom transitions follow the example below:

Before:
``` ts
import * as transition from "tns-core-modules/ui/transition";

export class CustomTransition extends transition.Transition {
    constructor(duration: number, curve: any) {
        super(duration, curve);
    }

    public createAndroidAnimator(transitionType: string): android.animation.Animator {
        var scaleValues = Array.create("float", 2);
        switch (transitionType) {
            case transition.AndroidTransitionType.enter:
            case transition.AndroidTransitionType.popEnter:
                scaleValues[0] = 0;
                scaleValues[1] = 1;
                break;
            case transition.AndroidTransitionType.exit:
            case transition.AndroidTransitionType.popExit:
                scaleValues[0] = 1;
                scaleValues[1] = 0;
                break;
        }
        var objectAnimators = Array.create(android.animation.Animator, 2);
        objectAnimators[0] = android.animation.ObjectAnimator.ofFloat(null, "scaleX", scaleValues);
        objectAnimators[1] = android.animation.ObjectAnimator.ofFloat(null, "scaleY", scaleValues);
        var animatorSet = new android.animation.AnimatorSet();
        animatorSet.playTogether(objectAnimators);

        var duration = this.getDuration();
        if (duration !== undefined) {
            animatorSet.setDuration(duration);
        }
        animatorSet.setInterpolator(this.getCurve());

        return animatorSet;
    }
}
```

After:
``` ts
import * as transition from "tns-core-modules/ui/transition";

export class CustomTransition extends transition.Transition {
    constructor(duration: number, curve: any) {
        super(duration, curve);
    }

    public createAndroidAnimation(transitionType: string): android.view.animation.Animation {
        const scaleValues = [];

        switch (transitionType) {
            case transition.AndroidTransitionType.enter:
            case transition.AndroidTransitionType.popEnter:
                scaleValues[0] = 0;
                scaleValues[1] = 1;
                break;
            case transition.AndroidTransitionType.exit:
            case transition.AndroidTransitionType.popExit:
                scaleValues[0] = 1;
                scaleValues[1] = 0;
                break;
        }
            
        const animationSet = new android.view.animation.AnimationSet(false);
        const duration = this.getDuration();
        if (duration !== undefined) {
            animationSet.setDuration(duration);
        }

        animationSet.setInterpolator(this.getCurve());
        animationSet.addAnimation(
            new android.view.animation.ScaleAnimation(
                scaleValues[0], 
                scaleValues[1], 
                scaleValues[0], 
                scaleValues[1]
            ));

        return animationSet;
    }
}
```
