* fix: crash on Android Tab-View NativeScript#6466
This fix has been tested in production with no new issues occurring.
Long-term solution would be one of the following, though:
1. reintroduce overrides for `saveState`/`restoreState` in the current PagerAdapter implementation (removed on this commit NativeScript@ac04ede#diff-f1459d509d1432b432c29bcd30e462fbL97)
2. use FragmentPagerAdapter
3. use FragmentStatePagerAdapter
Both 2 and 3 manage the save/restore cycles. The main difference between 2 and 3 is that 2 uses more memory, but allows for quicker switching between Fragments than 3. Since tabs should usually be limited to 5 or less, this may be the best choice to maintain performance, which is important for top level navigation tabs.
When I have more time I may experiment with these options myself to see what the difference to performance and memory consumption is for each.

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;
}
}

* feat(tabview): add tab text font size property
* chore(tabview): set tab font size default value
* chore(tabview): move font implementation to widget
* chore(tabview): fix font size get return type
Expose method on View class onBackPressed(). Third party controls
like RadSideDrawer can use this method to override the default Android
back button handling. By default the app closes.
Rework the frame api to support working with multiple Frames.
* frameModule.topmost() - now returns the last navigated Frame or
the currently selected tab item's Frame if the tab item's view is a
Frame.
* frameModule.getFrameById(id: string) - returns a navigated Frame by id.
* args.object.page.frame - can be used in page elements event handlers.
Returns the Frame of the current element's page.
* chore: Update madge-android npm script path
We want webpack's uglification to mangle function and class names
but that's what the current implementation of the CSS in {N} relys on
to get the CSS type for each view when targeted by CSS type selectors.
The implementation is changed a little so now the CSS type can be set
directly on the prototype of each View class or for TS, through decorator.
BREAKING CHANGES:
Extending classes requires marking the derived class with @CSSType
The root classes are not marked with CSSType and classes derived from ViewBase and View
will continue to work as expected. More concrete view classes (Button, Label, etc.) are
marked with @CSSType now and store their cssType on the prototype suppressing the previous
implementation that looked up the class function name. So clien classes that derive from one of
our @CSSType decorated classes will now have to be marked with @CSSType.
Fix image-source test for API 27
setupAsRootView now makes the component styleScope
set css, addCss & addCssFile makes view to be styleScopeHost which cannot be overriden later from parent
Android modals now call setupAsRootView
Small fixes on ios layouts
launch event fired in andriod too
Moved some requestLayout calls to ios files where they belongs
Fixed broken unit-tests
ios layout now run only for the innermost viewcontoller
ios layout for viewcontrollers now implemented with constraints
Added ios11 safeAreas layout support
onMeasure back for frame and tab-view so that they won't throw exception if measure is called on them
Page parents layout updated after page is layout so that inner layout flags are correct
Revert code that set currentEntry in fragment.transitions.android
Update tests & apps runtime version
Fix broken import in frame-tests
Revert TabView to fire loaded for all TabViewItems
iOS layout positioning now respects native properties like automaticallyAdjustsScrollViewInsets, edgesForExtendedLayout, extendedLayoutIncludesOpaqueBars, navigationBar.translucent, tabBar.translucent
Removed frame-tests.ios.ts - those tests are now invalid
Added new layout tests inside page-tests.ios.ts
Commented few asserts in scroll-view-tests
View now expose ios namespace with layoutView method and UILayoutViewController used by page, tab-view and application module
ViewBase now expose viewController property that should be set from all widgets that are using viewcontrollers internally (like Page, Frame, TabView)
ViewBase now sets ios property to either the view returned from createNativeView or to nativeViewProptected
fragment.transitions now use animation/transition start to add fragments to waitingQueue. Before we did it manually in navigate/goBack. This way we can reuse the fragment.transition when calling showDialog. Also when animation/transition ends we check the animation/transition to see if this fragment should be set as current.
Frame expose new loadViewFromEntry method (to load a view from URI)
Frame navigation happens once frame is loaded
Frame now supports Page as a child in XML
Fixed GridLayout row, rowSpan, column, columnSpan properties type
Fixed bug in GridLayout where add/remove of columns/rows won't update the internal state of the grid (backport from android when GridLayout is recycled)
ListView will no longer invalidate layout when cell is removed
Fixed bug in ScrollView ios where effectiveMinWidth/Height was multiplied to density (it is already on device pixels so no need to multiply)
TabView android now calls loaded only on the selected child (not all)
Core refactoring
recycleNativeView filed now accepts: "always" | "never" | "auto". Always will recycle the nativeView no matter if its nativeView or android proprties are accessed. Never will disable recycling. Auto will recycle it only if nativeView and android properties are not accessed.
