Our Android SDK is hosted as a GitHub package here: https://github.com/hotmic-wp/android-sdk

Make sure when installing that you follow this guide:

In the build.gradle (root), add the following repositories

• For the personal access token, granting the read: packages permission should be enough
• In the build.gradle(app), include the following dependency: `implementation 'io.hotmic.player:hotmic-android-sdk:1.4.1'`
• Minimum SDK version of the player SDK is 21
• Compile / Target SDK version of the player SDK is 30

The player screen in the SDK is implemented as a fragment:

• Single Activity: If you have a single activity app, then the player fragment can be launched in the desired layout container.
• Separate Activity: In case you want to launch the player in its own separate activity then you can create the activity in your app and then load the fragment into it

You will need an API_KEY that has been generated specifically for your application. In case you do not have this, please contact the HotMic team.

For fetching all streams to be listed to the user, call the below code:

The data will be returned as a list of HMStreamBasic Objects:

When the user taps on any of the listed stream, the app can then show the stream player using the following code:

• setStreamId - Mandatory – Sets the stream id (stream.id of the listing the user chose)
• setUICallback – Mandatory – Provide the callback interface that the SDk will use for fetching certain information, for notifying certain events, or to complete flows that only your app code can handle
• credential – Mandatory – Provide the api-key
• setAnalyticHandler – Optional – Provide the analytic callback interface which will be called by SDK whenever an analytic event occurs. The app code can then log the event as necessary
• show – Starts the player screen. Provide the layout container resource id, where the player fragment needs to be launched into

If the app wants to close the player, then call:

• reason - Analytic reason for the player closure, probable values will be USER_CLOSED, SIGNOUT

Once the player is closed, the SDK will make a call back on PlayerCallback.onPlayerClosed().

The SDK also might trigger a player closure. This may be in response to events like stream getting over, error in fetching the stream or the user leaving the stream from the player. Once the player is closed, the SDK will make a call back to PlayerCallback.onPlayerClosed().

If the user taps the device back key, and if the player is open, then the app should call:

HotMicPlayer.handleBackKeyPress(activity): Boolean

If the player consumes the key press (say for dismissing an overlay/dialog), then it will return true. The app should not handle the back press in this scenario. Else this will return false, and the app can handle the back press as it wants to.

The app can check if the player is open in multiple ways. It can check with the sdk by calling:

HotMicPlayer.isPlayerOpen(activity)

Or it can check whether a fragment is loaded in the ui player container:

supportFragmentManager.findFragmentById(R.id.<player_fragment_container>)

Picture in Picture Mode can be of two types:

1. For a single activity app, showing the player fragment in a PIP when navigating to other fragments in the app. This is achieved by reducing the player fragment layout container to the desired size and moving it to the required location.
2. Placing the app in the background by tapping the device Home button or by navigating to some other app

In both the cases the player has to resize itself so that in the PIP mode, the player displays just the video.

Also if the user taps on the PIP to get back to the expanded mode, the player will have to again change its UI to show all the layouts and controls.

To change the UI, manually (for scenario 1):

• enable: Set it to true for the player to show the PIP mode UI, false if the player is coming out of PIP and being expanded
• Returns true if the operation was success, false if the player is not open

For scenario 2 (android PIP mode), the player will change the UI itself, triggered by the android PIP callback. Note: this assumes that the activity has been enabled for PIP in the manifest. Refer https://developer.android.com/guide/topics/ui/picture-in-picture for more.

Also, for scenario 2, if the user closes the pip and at a later point of time returns to the app, then the app should show the UI with the player closed. To ensure this, add the below line in the activity onStart:

HotMicPlayer.checkPlayerStateOnStart(activity)

For displaying an ad, you can pass the view holding the ad (like the Google AdView) to the Player, using the following api:

It is assumed that the click interaction will be implemented in the view that is passed. The SDK is going to display the ad-banner with the passed view. The Ad will be displayed with an initial delay of 0 seconds, i.e., immediate, but this can be changed by passing a displayAfter value (in milliseconds). The Ad will be displayed for 10 seconds by default, this duration can also be changed by passing the right ttl value in the above function (in milliseconds)

If the ad is to be dismissed, before its auto removed, then the below api can be invoked

dismissHotMicAd(activity: FragmentActivity)

The below table lists the TextAppearance styles used in the app. The SDK does not have any fonts packaged with it, and hence the lack of font definitions in the below styles. You can change the appearance by defining the style with the same name in your app theme/style xml file

The table below lists the colors used in the app, for both day and night modes. You can change the colors by defining colors with the same name in your colors xml file(s)

fun getPlatformToken(): String

The platform token is required by the SDK to authenticate any requests with the HotMic Server. The SDK expects the app to return the platform token through this callback. Note that the HotMic Server expects the token to be constructed in a certain format, please contact the HotMic team to learn more.

Params: None

Returns: Platform Token

fun onRequestBugReport()

(OPTIONAL) User has requested to capture bug report. If the app is using any sort of bug capturing (like shake/instabug/etc), then trigger it

Params: None

fun onPlayerClosed()

(OPTIONAL) Called after the player is closed. Player closure can be triggered by the sdk on certain events like stream over, error. Or it can be triggered by the app by calling HotMicPlayer.closePlayer

Returns: Observable with the message string

fun isFollowing(uid: String): Boolean?

(OPTIONAL) If your application has feature to follow a user, then return true if the logged in user is following the user identified by the passed uid, return false if the user is not being followed. Default implementation is to return null, indicating that the follow feature is not available

Returns: true if you are following the user, false if not following, null if the feature is not present

fun getFollowData(uid: String): Observable<HMFollowData>?
