settings: fix loading disableCallIntegration

Samsung devices (of course) seem to stick with the earpiece if we first select
Bluetooth but then set speaker to false. Reverse the order to make everyone
happy.

This only applies to the generic and legacy handlers.

-## Building the sources
+## Development
 
-Node.js >= 8 and npm >= 6 are required.
-
-On Debian/Ubuntu systems, the required packages can be installed with:
-```
-sudo apt-get install npm nodejs
-cd jitsi-meet
-npm install
-```
-
-To build the Jitsi Meet application, just type
-```
-make
-```
-
-### 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/

 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`
 
-In source code form, the Android SDK dependencies are locked/pinned by package.json and package-lock.json of the Jitsi Meet project. To obtain the data, execute NPM in the parent directory:
+In source code form, the Android SDK dependencies are locked/pinned by package.json and package-lock.json of the Jitsi Meet project. To obtain the data, execute NPM in the jitsi-meet project directory:
 
-    $ (cd ..; npm install)
+    npm install
 
 This will pull in the dependencies in either binary format, or in source code format, somewhere under /node_modules/
 
-At the time of writing, there are two packages pulled in in binary format.
+Third-party React Native _modules_, which Jitsi Meet SDK for Android depends on, are download by NPM in source code 
+or binary form. These need to be assembled into Maven artifacts, and then published to your local Maven repository.
+A script is provided to facilitate this. From the root of the jitsi-meet project repository, run:
 
-To copy React Native to your local Maven repository, you can simply copy part of the directory structure that was pulled in by NPM:
+    ./android/scripts/release-sdk.sh /tmp/repo
 
-    $ cp -r ../node_modules/react-native/android/com /tmp/repo/
-
-In the same way, copy the JavaScriptCore dependency:
-
-    $ cp -r ../node_modules/jsc-android/dist/org /tmp/repo/
-
-Alternatively, you can use the scripts located in the android/scripts directory to publish these dependencies to your Maven repo.
-
-Third-party React Native _modules_, which Jitsi Meet SDK for Android depends on, are download by NPM in source code form. These need to be assembled into Maven artifacts, and then published to your local Maven repository. The SDK project facilitates this.
-
-To prepare, Configure the Maven repositories in which you are going to publish the SDK artifacts/binaries. In `android/sdk/build.gradle` as well as in `android/build.gradle` modify the lines that contain:
-
-    "file:${rootProject.projectDir}/../../jitsi-maven-repository/releases"
-
-Change this value (which represents the Maven repository location used internally by the Jitsi Developers) to the location of the repository that you'd like to use:
-
-    "file:/tmp/repo"
-
-Make sure to do this in both files! Each file should require one line to be changed.
-
-To create the release assembly for any _specific_ third-party React Native module that you need, you can execture the following commands, replace the module name in the examples below.
-
-    $ ./gradlew :react-native-webrtc:assembleRelease
-    $ ./gradlew :react-native-webrtc:publish
-
-You build and publish the SDK itself in the same way:
-
-    $ ./gradlew :sdk:assembleRelease
-    $ ./gradlew :sdk:publish
-
-Alternatively, you can assemble and publish _all_ subprojects, which include the react-native modules, but also the SDK itself, with a single command:

-    $ ./gradlew assembleRelease publish
+This will build and publish the SDK, and all of its dependencies to the specified Maven repository (`/tmp/repo`) in

-This class encapsulates a high level API in the form of an Android `Activity`
-which displays a single `JitsiMeetView`.
+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.
 
 ### 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.
 
-#### setPictureInPictureEnabled(boolean)
+### JitsiMeetConferenceOptions
 
-Sets whether Picture-in-Picture is enabled. If not set, Jitsi Meet SDK
-automatically enables/disables Picture-in-Picture based on native platform
-support.
+This object encapsulates all the options that can be tweaked when joining
+a conference.
 
-NOTE: Must be called (if at all) before `loadURL`/`loadURLString` for it to take
-effect.
+Example:
 
-#### setWelcomePageEnabled(boolean)
+```java
+JitsiMeetConferenceOptions options = new JitsiMeetConferenceOptions.Builder()
+    .setServerURL(new URL("https://meet.jit.si"))
+    .setRoom("test123")
+    .setAudioMuted(false)
+    .setVideoMuted(false)
+    .setAudioOnly(false)
+    .setWelcomePageEnabled(false)
+    .build();
+```
 
-Sets whether the Welcome page is enabled. See `isWelcomePageEnabled` for more
-information.
+See the `JitsiMeetConferenceOptions` implementation for all available options.
 
-NOTE: Must be called (if at all) before `loadURL`/`loadURLString` for it to take
-effect.
