android: workaround for building

Somehow the bundle doesn't get included in the APK when I build this branch on
one laptop, but works on another, go figure. All of this has changed with the RN
0.59 update, so this is just a band-aid for 19.0 builds.

+## Building the sources
 
-You can also sign up for our open beta testing here:
+Node.js >= 8 and npm >= 6 are required.
 
-* [Android](https://play.google.com/apps/testing/org.jitsi.meet)
-* [iOS](https://testflight.apple.com/join/isy6ja7S)
+On Debian/Ubuntu systems, the required packages can be installed with:
+```
+sudo apt-get install npm nodejs
+cd jitsi-meet
+npm install
+```
 
-## Development
+To build the Jitsi Meet application, just type
+```
+make
+```
 
-For web development see [here](doc/development.md), and for mobile see [here](doc/mobile.md).
+### Working with the library sources (lib-jitsi-meet)
+
+By default the library is build from its git repository sources. The default dependency path in package.json is :
+```json
+"lib-jitsi-meet": "jitsi/lib-jitsi-meet",
+```
+
+To work with local copy you must change the path to:
+```json
+"lib-jitsi-meet": "file:///Users/name/local-lib-jitsi-meet-copy",
+```
+
+To make the project you must force it to take the sources as 'npm update' will not do it.
+```
+npm install lib-jitsi-meet --force && make
+```
+
+Or if you are making only changes to the library:
+```
+npm install lib-jitsi-meet --force && make deploy-lib-jitsi-meet
+```
+
+Alternative way is to use [npm link](https://docs.npmjs.com/cli/link).
+It allows to link `lib-jitsi-meet` dependency to local source in few steps:
+
+```bash
+cd lib-jitsi-meet
+
+#### create global symlink for lib-jitsi-meet package
+npm link
+
+cd ../jitsi-meet
+
+#### create symlink from the local node_modules folder to the global lib-jitsi-meet symlink
+npm link lib-jitsi-meet
+```
+
+So now after changes in local `lib-jitsi-meet` repository you can rebuild it with `npm run install` and your `jitsi-meet` repository will use that modified library.
+Note: when using node version 4.x, the make file of jitsi-meet do npm update which will delete the link, no longer the case with version 6.x.
+
+If you do not want to use local repository anymore you should run
+```bash
+cd jitsi-meet
+npm unlink lib-jitsi-meet
+npm install
+```
+### Running with webpack-dev-server for development
+
+Use it at the CLI, type
+```
+make dev
+```
+
+By default the backend deployment used is `beta.meet.jit.si`, you can point the Jitsi-Meet app at a different backend by using a proxy server. To do this set the WEBPACK_DEV_SERVER_PROXY_TARGET variable:
+```
+export WEBPACK_DEV_SERVER_PROXY_TARGET=https://your-example-server.com
+make dev
+```
+
+The app should be running at https://localhost:8080/

 ## Security
+WebRTC today does not provide a way of conducting multiparty conversations with
+end-to-end encryption. As a matter of fact, unless you consistently vocally
+compare DTLS fingerprints with your peers, the same goes for one-to-one calls.
+As a result when using a Jitsi Meet instance, your stream is encrypted on the
+network but decrypted on the machine that hosts the bridge.
 
-The security section here was starting to feel a bit too succinct for the complexity of the topic, so we created a post that covers the topic much more broadly here: https://jitsi.org/security
+The Jitsi Meet architecture allows you to deploy your own version, including
+all server components, and in that case your security guarantees will be roughly
+equivalent to these of a direct one-to-one WebRTC call. This is what's unique to
+Jitsi Meet in terms of security.

 If you want to use a SDK that is built from source, you will likely benefit from composing a local Maven repository that contains these dependencies. The text below describes how you create a repository that includes both the SDK as well as these dependencies. For illustration purposes, we'll define the location of this local Maven repository as `/tmp/repo`

 This will pull in the dependencies in either binary format, or in source code format, somewhere under /node_modules/
 
-Third-party React Native _modules_, which Jitsi Meet SDK for Android depends on, are download by NPM in source code

+To copy React Native to your local Maven repository, you can simply copy part of the directory structure that was pulled in by NPM:
 
-This will build and publish the SDK, and all of its dependencies to the specified Maven repository (`/tmp/repo`) in
-this example.

+
+In the same way, copy the JavaScriptCore dependency:
+

+Starting with SDK version 1.22, a Glide module must be provided by the host app.
+This makes it possible to use the Glide image processing library from both the
+SDK and the host app itself.

+You can use the code in `JitsiGlideModule.java` and adjust the package name.
+When building, add the following code in your `app/build.gradle` file, adjusting
+the Glide version to match the one in https://github.com/jitsi/jitsi-meet/blob/master/android/build.gradle

 ### JitsiMeetActivity
 
-This class encapsulates a high level API in the form of an Android `FragmentActivity`
-which displays a single `JitsiMeetView`. You can pass a URL as a `ACTION_VIEW`
-on the Intent when starting it and it will join the conference, and will be
-automatically terminated (finish() will be called on the activity) when the
-conference ends or fails.
+This class encapsulates a high level API in the form of an Android `Activity`
+which displays a single `JitsiMeetView`.
 
 ### JitsiMeetView
 
 The `JitsiMeetView` class is the core of Jitsi Meet SDK. It's designed to
 display a Jitsi Meet conference (or a welcome page).
 
-#### join(options)
-
-Joins the conference specified by the given `JitsiMeetConferenceOptions`.
-
-#### leave()
-
-Leaves the currently active conference. If the welcome page is enabled it will
-go back to it, otherwise a black window will be shown.
-
 #### dispose()
 
 Releases all resources associated with this view. This method MUST be called
 when the Activity holding this view is going to be destroyed, usually in the
 `onDestroy()` method.
 
+#### getDefaultURL()
+
+Returns the default base URL used to join a conference when a partial URL (e.g.
+a room name only) is specified to `loadURLString`/`loadURLObject`. If not set or
+if set to `null`, the default built in JavaScript is used: https://meet.jit.si.
+
 #### getListener()
 
 Returns the `JitsiMeetViewListener` instance attached to the view.
 
+#### isPictureInPictureEnabled()
+
+Returns `true` if Picture-in-Picture is enabled; `false`, otherwise. If not
+explicitly set (by a preceding `setPictureInPictureEnabled` call), defaults to
+`true` if the platform supports Picture-in-Picture natively; `false`, otherwise.
+
+#### isWelcomePageEnabled()
+
+Returns true if the Welcome page is enabled; otherwise, false. If false, a black
+empty view will be rendered when not in a conference. Defaults to false.
+
+#### loadURL(URL)
+
+Loads a specific URL which may identify a conference to join. If the specified
+URL is null and the Welcome page is enabled, the Welcome page is displayed
+instead.
+
+#### loadURLString(String)
+
+Loads a specific URL which may identify a conference to join. If the specified
+URL is null and the Welcome page is enabled, the Welcome page is displayed
+instead.
+
+#### loadURLObject(Bundle)
+
+Loads a specific URL which may identify a conference to join. The URL is
+specified in the form of a Bundle of properties which (1) internally are
+sufficient to construct a URL (string) while (2) abstracting the specifics of
+constructing the URL away from API clients/consumers. If the specified URL is
+null and the Welcome page is enabled, the Welcome page is displayed instead.
+
+Example:
+
+```java
+Bundle config = new Bundle();
+config.putBoolean("startWithAudioMuted", true);
+config.putBoolean("startWithVideoMuted", false);
+Bundle urlObject = new Bundle();
+urlObject.putBundle("config", config);
+urlObject.putString("url", "https://meet.jit.si/Test123");
+view.loadURLObject(urlObject);
+```
+
+#### setDefaultURL(URL)
+
+Sets the default URL. See `getDefaultURL` for more information.
+
+NOTE: Must be called before (if at all) `loadURL`/`loadURLString` for it to take
+effect.
+
 #### setListener(listener)
 
 Sets the given listener (class implementing the `JitsiMeetViewListener`
 interface) on the view.
 
-### JitsiMeetConferenceOptions
+#### setPictureInPictureEnabled(boolean)
 
-This object encapsulates all the options that can be tweaked when joining
-a conference.
+Sets whether Picture-in-Picture is enabled. If not set, Jitsi Meet SDK
+automatically enables/disables Picture-in-Picture based on native platform
+support.
 
-Example:
+NOTE: Must be called (if at all) before `loadURL`/`loadURLString` for it to take
+effect.
 
-```java
-JitsiMeetConferenceOptions options = new JitsiMeetConferenceOptions.Builder()
-    .setServerURL(new URL("https://meet.jit.si"))
-    .setRoom("test123")
-    .setAudioMuted(false)
-    .setVideoMuted(false)
-    .setAudioOnly(false)
-    .setWelcomePageEnabled(false)
-    .build();
-```
+#### setWelcomePageEnabled(boolean)
 
-See the `JitsiMeetConferenceOptions` implementation for all available options.
+Sets whether the Welcome page is enabled. See `isWelcomePageEnabled` for more
+information.
