[RN] Add initial Jitsi Meet SDK for Android

Dames en heren, welcome to Jitsi Meet SDK for Android, the Jitsi Meet library
for Android.

The Jitsi Meet SDK encapsulates React Native and all the dependencies Jitsi
Meet has so other aopplications can integrate it easily.

Unlike iOS, creating "fat" libraries is not allways (if at all) possible on
Android, however, effort was put into making the integration as easy as
possible.

While React Native can be embedded in native applications, I don't think it was
designed to be embedded as part of an Android library, hidden away from the
application using it. This surfaced as a number of issues which had to be
addressed specifically due to our use-case:

- Activity lifecycle methods must be linked with the React Native engine, so the
  library provides wrapper methods.
- Custom fonts have to be manually added as assets, since the provided gradle
  script doesn't work properly in a library target.
- The RN packager has to be manually triggered since the gradle script will no
  longer do it for us.

At this stage, the Jitsi Meet application is just a small single activity
application which uses the Jitsi Meet SDK to create a single activity which
represents the entire application. Events and external conference handling are
forthcoming.

PS: Yours truly would like to add that it was a lot more fun to work on the iOS
side of things.

+# Jitsi Meet for Android
+
+This directory contains the source code for Jitsi Meet for Android (the
+application) and the Jitsi Meet SDK for Android.
+
+## Jitsi Meet SDK
+
+Jitsi Meet SDK is an Android library which embodies the Jitsi Meet experience,
+gift-wrapped so other applications can use it. Example use:
+
+```java
+package org.jitsi.example;
+
+import android.support.v7.app.AppCompatActivity;
+import android.os.Bundle;
+
+import org.jitsi.meet.sdk.*;
+
+
+public class CustomActivity extends AppCompatActivity {
+    private JitsiMeetView jitsiMeetView;
+
+    @Override
+    public void onBackPressed() {
+        if (!JitsiMeetView.onBackPressed()) {
+            // Invoke the default handler if it wasn't handled by React.
+            super.onBackPressed();
+        }
+    }
+
+    @Override
+    protected void onCreate(Bundle savedInstanceState) {
+        super.onCreate(savedInstanceState);
+
+        jitsiMeetView = new JitsiMeetView(this);
+        jitsiMeetView.loadURL(null);
+
+        setContentView(jitsiMeetView);
+    }
+
+    @Override
+    public void onNewIntent(Intent intent) {
+        JitsiMeetView.onNewIntent(intent);
+    }
+
+    @Override
+    protected void onDestroy() {
+        super.onDestroy();
+        JitsiMeetView.onHostDestroy(this);
+    }
+
+    @Override
+    protected void onPause() {
+        super.onPause();
+        JitsiMeetView.onHostPause(this);
+    }
+
+    @Override
+    protected void onResume() {
+        super.onResume();
+        JitsiMeetView.onHostResume(this);
+    }
+
+}
+```
+
+Alternatively, you can use the `JitsiMeetBaseActivity` class, which already has
+all activity lifecycle methods hooked up:
+
+```java
+package org.jitsi.example;
+
+import org.jitsi.meet.sdk.*;
+
+
+public class MainActivity extends JitsiMeetBaseActivity {
+}
+
+```
+
+### JitsiMeetBaseActivity
+
+This class encapsulates a high level API in the form of an Android activity
+which displays a single `JitsiMeetView` views.
+
+#### loadURL(url)
+
+See JitsiMeetView.loadURL.
+
+
+### JitsiMeetView
+
+The `JitsiMeetView` class is the core of Jitsi Meet SDK. It's designed to
+display a Jitsi Meet conference view (or a welcome page).
+
+#### loadURL(url)
+
+Loads the given URL and joins the conference which is being pointed to. If null,
+it will load the welcome page.
+
+#### onBackPressed()
+
+Helper method which should be called from the activity's `onBackPressed` method.
+If this function returns `true` it means the action was handled and thus no
+extra processing is required, otherwise the application should call the parent's
+`onBackPressed` method.
+
+This is a static method.
+
+#### onHostDestroy(activity)
+
+Helper method which should be called from the activity's `onDestroy` method.
+
+This is a static method.
+
+#### onHostPause(activity)
+
+Helper method which should be called from the activity's `onPause` method.
+
+This is a static method.
+
+#### onHostResume(activity)
+
+Helper method which should be called from the activity's `onResume` method.
+
+This is a static method.
+
+#### onNewIntent(intent)
+
+Helper method for integrating the *deep linking* functionality. If your
+application's activity is launched in "singleTask" mode this method should
+be called from the activity's `onNewIntent` method.
+
+This is a static method.
