fix(device-selection): use device kind when getting current devices (#4059)

Devices of different kinds can have the same id, such as speaker
and mic both being default. Using id only can then lead to
incorrectly setting device descriptions in the current devices
object.

-## Build
+## Build your own, or use a pre-build SDK artifacts/binaries
 
-1. Install all required [dependencies](https://github.com/jitsi/jitsi-meet/blob/master/doc/mobile.md).
+Jitsi conveniently provides a pre-build SDK artifacts/binaries in its Maven repository. When you do not require any
+modification to the SDK itself or any of its dependencies, it's suggested to use the pre-build SDK. This avoids the
+complexity of building and installing your own SDK artifacts/binaries.
 
-2. ```bash
-   cd android/
-   ./gradlew :sdk:assembleRelease
-   ```
+### Use pre-build SDK artifacts/binaries
 
-3. Configure the Maven repositories in which you are going to publish the
-   artifacts/binaries during step 4. Modify
-   `"file:${rootProject.projectDir}/../../../jitsi/jitsi-maven-repository/releases"`
-   in adroid/sdk/build.gradle for Jitsi Meet SDK for Android and/or
-   `"file:${rootProject.projectDir}/../../../jitsi/jitsi-maven-repository/releases"`
-   in android/build.gradle for the third-party react-native modules which Jitsi
-   Meet SDK for Android depends on and are not publicly available in Maven
-   repositories. Generally, if you are modifying the JavaScript code of Jitsi
-   Meet SDK for Android only, you will very likely need to consider the former
-   only.
-
-4. Publish the Maven artifact/binary of Jitsi Meet SDK for Android in the Maven
-   repository configured in step 3:
-
-   ```bash
-   ./gradlew :sdk:publish
-   cd ../
-   ```
-
-   If you would like to publish a third-party react-native module which Jitsi
-   Meet SDK for Android depends on and is not publicly available in Maven
-   repositories, replace `sdk` with the name of the react-native module. For
-   example, to publish react-native-webrtc:
-
-   ```bash
-   ./gradlew :react-native-webrtc:publish
-   ```
-
-## Install
-
-Add the Maven repository
+In your project, add the Maven repository
 `https://github.com/jitsi/jitsi-maven-repository/raw/master/releases` and the
-dependency `org.jitsi.react:jitsi-meet-sdk:1.9.0` into your `build.gradle`.
+dependency `org.jitsi.react:jitsi-meet-sdk` into your `build.gradle` files.
 
-## API
+The repository typically goes into the `build.gradle` file in the root of your project:
+
+```gradle
+allprojects {
+    repositories {
+        google()
+        jcenter()
+        maven {
+            url "https://github.com/jitsi/jitsi-maven-repository/raw/master/releases"
+        }
+    }
+}
+```
+
+Dependency definitions belong in the individual module `build.gradle` files:
+
+```gradle
+dependencies {
+    // (other dependencies)
+    implementation ('org.jitsi.react:jitsi-meet-sdk:2.+') { transitive = true }
+}
+```
+
+### Build and use your own SDK artifacts/binaries
+
+<details>
+<summary>Show building instructions</summary>
+
+Start by making sure that your development environment [is set up correctly](https://github.com/jitsi/jitsi-meet/blob/master/doc/mobile.md).
+
+A note on dependencies: Apart from the SDK, Jitsi also publishes a binary Maven artifact for some of the SDK dependencies (that are not otherwise publicly available) to the Jitsi Maven repository. When you're planning to use a SDK that is built from source, you'll likely use a version of the source code that is newer (or at least _different_) than the version of the source that was used to create the binary SDK artifact. As a consequence, the dependencies that your project will need, might also be different from those that are published in the Jitsi Maven repository. This might lead to build problems, caused by dependencies that are unavailable.
+
+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 jitsi-meet project directory:
+
+    npm install
+
+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 
+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:
+
+    ./android/scripts/release-sdk.sh /tmp/repo
+
+This will build and publish the SDK, and all of its dependencies to the specified Maven repository (`/tmp/repo`) in
+this example.
+
+You're now ready to use the artifacts. In _your_ project, add the Maven repository that you used above (`/tmp/repo`) into your top-level `build.gradle` file:
+
+    allprojects {
+        repositories {
+            maven { url "file:/tmp/repo" }
+            google()
+            jcenter()
+        }
+    }
+
+You can use your local repository to replace the Jitsi repository (`maven { url "https://github.com/jitsi/jitsi-maven-repository/raw/master/releases" }`) when you published _all_ subprojects. If you didn't do that, you'll have to add both repositories. Make sure your local repository is listed first!
+
+Then, define the dependency `org.jitsi.react:jitsi-meet-sdk` into the `build.gradle` file of your module:
+
+    implementation ('org.jitsi.react:jitsi-meet-sdk:+') { transitive = true }
+
+Note that there should not be a need to explicitly add the other dependencies, as they will be pulled in as transitive
+dependencies of `jitsi-meet-sdk`.

+
+## Using the API
 
 Jitsi Meet SDK is an Android library which embodies the whole Jitsi Meet
 experience and makes it reusable by third-party apps.
 
+First, add Java 1.8 compatibility support to your project by adding the
+following lines into your `build.gradle` file:
+
+```
+compileOptions {
+    sourceCompatibility JavaVersion.VERSION_1_8
+    targetCompatibility JavaVersion.VERSION_1_8
+}
+```
+
 To get started, extends your `android.app.Activity` from
 `org.jitsi.meet.sdk.JitsiMeetActivity`:
 
@@ -61,25 +110,42 @@ public class MainActivity extends JitsiMeetActivity {
 ```
 
 Alternatively, you can use the `org.jitsi.meet.sdk.JitsiMeetView` class which
-extends `android.view.View`:
+extends `android.view.View`.
+
+Note that this should only be needed when `JitsiMeetActivity` cannot be used for
+some reason. Extending `JitsiMeetView` requires manual wiring of the view to
+the activity, using a lot of boilerplate code. Using the Activity instead of the
+View is strongly recommended.

+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.
 
-#### getPictureInPictureEnabled()
-
-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.
-
-#### getWelcomePageEnabled()
-
-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 `getWelcomePageEnabled` 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.
+### JitsiMeetActivityDelegate
