Add Toggle for Android Immersive FullScreen Layout

Note:
- this package is Android only, and Immersive Full-Screen Mode is first introduced since [Android 4.4 (API Level 19)][l:immersive]
- check [release][l:release] for ChangeLog
- `v2.0.0` and above will build with `gradle@>=3`
- `v1.0.0` and above should be used with `react-native@>=0.47`
- `v0.0.5` should be used with `react-native@<=0.46`

## Installation Process

Download from npm: `npm i react-native-immersive`

Run `react-native link` to automatically link the library.

#### manual link process

Edit `android/settings.gradle`:

```diff
+ include ':react-native-immersive'
+ project(':react-native-immersive').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-immersive/android')
```

Edit `android/app/build.gradle`: (for versions before `v2.0.0`, use `compile` instead of `implementation` for `gradle@<=2`)

```diff
dependencies {
implementation fileTree(dir: "libs", include: ["*.jar"])
implementation "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"
implementation "com.facebook.react:react-native:+" // From node_modules
+ implementation project(':react-native-immersive')
}
```

Edit `android/app/src/main/java/.../MainApplication.java`:

```diff
+ import com.rnimmersive.RNImmersivePackage;

...

@Override
protected List getPackages() {
return Arrays.asList(
new MainReactPackage()
+ , new RNImmersivePackage()
);
}
```

## Basic Usage

```js
import { Immersive } from 'react-native-immersive'

// methods (Android only, will throw Error on iOS in __DEV__ mode)
Immersive.on()
Immersive.setImmersive(true)

Immersive.off()
Immersive.setImmersive(false)
```

## Restore Immersive State

The Immersive State do not last forever (SYSTEM_UI_FLAG_IMMERSIVE_STICKY is not sticky enough).
The Immersive State will get reset when:

- coming back to active AppState
- after Keyboard opening
- after Alert opening
- after Modal opening

To restore the Immersive State, add an additional listener.

```js
// listener for Immersive State recover
const restoreImmersive = () => {
__DEV__ && console.warn('Immersive State Changed!')
Immersive.on()
}
Immersive.addImmersiveListener(restoreImmersive)
Immersive.removeImmersiveListener(restoreImmersive)
```

The Native Module itself will cover some basic Immersive State change (but not something like Modal + Alert).
To get all Immersive State change, edit `android/app/src/main/java/.../MainActivity.java`:

```diff
+ import com.rnimmersive.RNImmersiveModule;
...

public class MainActivity extends ReactActivity {
...
+ @Override
+ public void onWindowFocusChanged(boolean hasFocus) {
+ super.onWindowFocusChanged(hasFocus);
+
+ if (hasFocus && RNImmersiveModule.getInstance() != null) {
+ RNImmersiveModule.getInstance().emitImmersiveStateChangeEvent();
+ }
+ }
}
```

## Sample Component

Change the code of `index.js` for testing:
[example/index.sample.js](example/index.sample.js)

## Common Problem

#### Unified Compile Version
###### solution from SudoPlz [react-native-keychain#68][l:issue68]

When compile ReactNative android,
different package may set different compileSdkVersion and buildToolsVersion.

To force all the submodules to use the specified compileSdkVersion and buildToolsVersion,
add the following code to `android/build.gradle`:

```
subprojects {
afterEvaluate {project ->
if (project.hasProperty("android")) {
android {
compileSdkVersion 27
buildToolsVersion "27.0.3"
}
}
}
}
```

#### Packages missing from JCenter
###### solution from kerwin1 [react-native-vector-icons#605][l:issue605]

Around 2018/12/10,
JCenter received a request from Google, to remove several binaries from their repository.
But some repos were removed by mistake,
causing error like: `Could not resolve com.android.tools.build:gradle:2.3.+.`.

As google removed `gradle v2.2.*` from `JCenter`, so many plugins not work.
To patch repositories for specific submodules,
add the following code to `android/build.gradle`:

```
buildscript { ... }
allprojects { ... }
subprojects {
if (project.name.contains('react-native-immersive')) {
buildscript {
repositories {
jcenter()
maven { url "https://dl.bintray.com/android/android-tools/" }
}
}
}
}
```
